Question Cell Coverage Terrible - Samsung Galaxy Z Fold3

Came from Unlocked Note20 Ultra which I had zero issues with cellular reception on Verizon.
Bought the Unlocked Z Fold3 and have terrible cellular reception in nearly all places I never had issues on the Note20 Ultra.
Are the antenna bands different?
Is the new metal back or frame drastically reducing range?

You got a bad phone. No issues on mine, same as S21ULTRA, and note 20

Try to change your SIM. It helped me.

I also changed the N20U to the FZ3 and I did not notice anything like that. I think the FZ3 has an even better coverage than the Note.
The only difference is that it switches more often from LTE to 3G, thus VoLTE turns off. But it's generally very good.
BTW WiFi coverage is much better.

I'm having the same type of issues. T-mobile here in areas where I had solid 5G or LTE I either have no service or it flips to edge/lte/5g. Probably going to send it back at this point.

Im tmobile and all is the same or better then my notw 10 plus was.
I did get a new sim card for 5g

I used the new sim card from Samsung as well R15. I had T-Mobile do a reset from their end and I did a factor reset and didn't use smart switch this time. I'm going to be traveling today so we'll see if it happens again. Fingers crossed.

T-Mobile in north Texas. I'm getting the same results as my Note 10+ did, using the same sim. 5G data is very fast. May be an issue with yours.

Can we say either way about the cellular performance?
Has anyone seen a video comparing F2 vs F3 cellular performance?

Don't use SmartSwitch if migrating to a different device or OS version... its not that smart.
Probably ok for migrating just your contacts though.
Next reload on my 10+ I'll test it same to same and see how it does. Definitely don't use it to back up critical data though... remember Kies?

AT&T in N Texas, from N20U to ZF3...Same. I get some network issues occasionally.
You might need a new sim, I'm thinking about doing that myself.
My fold is also the unlocked from Sammy.

New sim, install yourself, handle it like a stick of ram.
ESD can damage it; very little built in out of circuit protection. Most phone store salespeople handle them extremely carelessly... you pay the price when it fails sometimes even months, years latter. Most sim cards fail because of previous ESD exposure just like ram sticks.

Oh, I'm familiar. Build computers before, always upgrade my RAM myself, and have 3 Pi's running 3D printers. But that info is always helpful to someone.

I've noticed this too in low coverage areas. My oneplus 7t

Why not? I used smart switch with no issues at all. Transferred everything from my oneplus 7t to the z fold 3. All it does is transfer general data and install the apk files that were on your previous data partition. It doesn't transfer any device specific apps or files.
Please back up your comments with reason and/or experience so you don't have people questioning things that they then have to spend ample time looking up

Lots of needlessly destroyed ram sticks out there...
Sims may have some input protection but you see how small they are.

I've seen it screw up myself with contacts.
Seen it's predecessor Kies screw up.
If it works, fine, but don't rely on it.
It can save home settings, themes, etc and that can cause issues especially between devices.
Don't kill the messenger... others here have had trouble with it as well

It is not clear to me whether all problem are with 5G reception, 4G, or switching between the two.

I'm having terrible reception issues with my Z3. My network keeps shutting off and on. USA Verizon.

I have to undo what I wrote early. The Z3 has serious coverage problem. Very often, the signal goes missing, or the 3G-4G-5G networks switch like crazy

Broken record poster asks if this is a VZW problem in the US, or a bigger problem?
Also, there are problems with the phone folded or open?

[Q] Note 8 LTE

There isn't a forum for the lte version so I'm asking the question here. Does anyone know if the AT&T version will use the same sim as the note2? I want to switch the sim between devices when I drive. A portable inet enabled nav system for my car.
Yes, it takes a micro sim. Same as the note II. Will come with a "warm sim" installed to support session based (prepaid) pricing as well.
update: I just swapped mine out and it won't latch in place... not sim related, as none of my sims snap in. Silly spring loaded sim slots......

Weird. Do you think no microsim will fit? If it did, do you think you could use it as a giant phone on your car dash? It would be perfect as an internet connected car navigation replacement.
They fit perfectly. I just have one unit where the latch mechanism is messed up.
As far as the usage described... the AT&T variant does not function as a phone as configured. It is considered a connected tablet and no voice services are included in the stock software. That said, it makes a hell of a navi. You just wont be making standard cellular calls from it as well.

That's too bad. I was hoping I wouldn't have to tether my gs4 to the tablet and use Skype and google voice with it maybe ill just wait for that Sony Xperia z ultra as my next phone. The note2 wasn't big enough to use effectively from my dash.

You would be able to use skype if you have a data plan active on the Note 8.0. It is LTE and working great for me for 3 days now. Of course it would need its own data plan, or if you are on a Mobile Share plan it is only 10 bux to add to your existing data bucket. Not bad imho.

What service provider are you using for your LTE?
Interesting. I had the HK LTE version, and its SIM slot failed - not a latching problem - just started telling me the SIM card wasn't there after a couple of days.

As for same size (micro) yes. As for functioning...NO!! The Note 8 LTE will only function on data based sim cards. Such as a mobile Wi-Fi hot spot sim card.
Has anybody found any ROM's for the AT&T version yet?

Are you sure a regular voice/data SIM won't just work for data only in the device? I really makes me angry that AT&T has all the phone stuff taken out. I want a tablet that I can use as a phone also. I may just buy the international version and not worry about LTE.

Nope. You can't even root it yet. No one has bothered to find an exploit since so few people actually own an AT&T version right now. haha Even if it achieves wider adoption, let's be honest...tablets with cell connections are usually frowned upon by the XDA and other dev-friendly communities. They'll always be treated as second-class citizens around here because they have no hipster cred 'round these parts. If we were with the in crowd, we'd buy a WiFI-only model and just tether it to our phones. :silly: A lot of people in these communities just see absolutely no point to, and thus thumb their nose at, a tablet with an LTE connection. You can give them reason after reason why they're useful, but it falls on deaf ears more times than not.
Don't expect ROMs or root for the AT&T model until there are more people that actually own one.

If you want it from the horse's mouth call AT&T store. As for me I went with the 5100 international version.

The rep at my store said that I could change the sim over to a voice plan any time I want but it will cost more per month. $10 for the data only plan compared to $25 for the voice/data plan (like any other device). I don't see a point in spending the money until somebody figures out how to get calls working. He also said that the sim would still work in the tab after changing to a voice plan. The question is: is the hardware capable of supporting voice calls? If so, then I'm confident that somebody will figure out how fairly quickly.

No. The AT&T SGH-I467 model does not have the phone hardware and therefore is incapable of making calls. Look at a picture of the international 3G model and compare it to a picture of the AT&T model. You'll notice the AT&T model doesn't have an earpiece at the top like the international model does. You can use the AT&T model to make calls via VoIP services like Skype, but if you want to make calls over a cell network, you're out of luck. If that's a feature that you really, really need, then you'll have to buy an international unlocked 3G model.
As a side note, the official Samsung flip cover for the Note 8.0 is designed to fit all models worldwide. This means it has a cutout in the top for the earpiece that you find on the international 3G model. It looks a little hokey when you put it on the AT&T or WiFi-only models since there's nothing there to plug that hole.

Sorry, I wasn't very clear. By hardware I meant the radio side of things. I agree that the microphone and speaker are definately not configured for calls. Are you saying that you have reason to beleive that it is impossible to develop a way to place calls via bluetooth headset?

Yes, people have tried to place calls and send native text messages. It appears that there is no usable radio hardware inside the device other than that which is required for data.
Now, it's possible that the hardware IS there but the baseband firmware simply disables it, but there's no proof of that. Unless we could hack the radio firmware somehow (not likely) or do a teardown of the tablet, we'll never know for 100% sure. But, as things sit right now, you will neither be able to make phone calls of any kind, nor be able to send native text messages to or from the tablet, at all with an SGH-I467 AT&T model because either there's no radio hardware or the I467UAMDF radio software has disabled the phone hardware entirely.

s4 mini duos network problems

Hello,
I appeal to all the users that have samsung galaxy s4 mini duos (i9192) to give me a honest opinion on their experience usage about this issue
I want to buy the phone because i have 2 sims, work and home and need both always on but i've been read that this phone has major problems with network signal such as:
"Poor network performance. I'm forced to restart 4 to 5 times per day to regain the network access. I checked from my service providers, no issues on their part. Dual Sim a failure. Apart from network issues, the design, ram performance are average. I'll recommend not to buy this instrument unless the dual-sim network problem is rectified."
Like this, there are many more in samsung phone forum.
Anyone can give me their opinion?
False. I'm using it without problems with two sims work/private. Signal strength may be lower, but it's not so bad. Device is very fast, in antutu it has more points than 4 core htc one x+ or galaxy s3.
Software is bit buggy, but nothing serious.

Seems that the phone in bad coverage areas lost signal and don't regain signal unless you restart the phone or the network. Have you already been in bad coverage areas?
It will regain signal. For example yesterday - I was in underground parking lot and signal was very poor to none, but somehow I've got the incoming call when moving to other spot.
Maybe it's firmware related. I've updated manually to amh2 version through odin. Mine new csc is ser - Russia

Anyone else that has not experienced this problems?
I would like to know this also, I'm considering buying it solely because of the "Dual Sim" but I keep reading lots of people complaining about the signal issues.
I dont have any problems with my I9192 been in my hands for 2 months by now the network problem you describe it's very rare just couple of times since I've been using it but I've turn on and off airplane mode
for me it's a really good phone

Same problem
I also have the duos version. Once the signal is lost/falls in the dead spot region, it doesn't come back a automatically. Fed up with this.. after buying such a high end phone, restarting all the time to get network! What is the use of fast processor and all stuff if we can't make a phone call with it? And after reading the comments on the below page, it is clear that this is a known issue of the model:
gsmarena.com/samsung_i9190_galaxy_s4_mini-reviews-5375.php
Any solution for this? The handset has turned out to be useless.
I have not had a problem like this with mine, it works perfect. I live in a bad signal area and if I go down stairs in my house the phone will lose the signal , when I go back up stairs the phone always regains the signal with no problems.
I can't fault this phone, it's ten times better than my last one, HTC Desire V

Only the fact that you mentioned you have to do airplane mode 2 times is just severe enough, because in a phone with this price range that's a problem that should NEVER occur, and you can be the lucky guy that just has good coverage signal all of the time.
I came to the conclusion that it happens with much moore models than the ones that not happen.
I'm going to order the phone even with this feedback hoping that i have a flash of luck and my phone doesn't have the problems, because i've been waiting months for a dual sim phone with top performance and this seems to be the ideal phone to me.
I will post my experience here, if anything goes wrong i will try to sell it.

Same Issue with Samsung GT-I9192
Hi All,
I am facing the same issue with my Samsung GT-I9192, which I purchased on 1st Sep.
I am using 2 simcards, one being Vodafone and the other Idea, India region.
Surprisingly the issue is only with Vodafone, where the signal after dropping (very frequently) does not refresh.
In case of Idea simcard, the signal refresh is working fine.
I am not able to understand if the problem is with the service provider, sim card, hardware or the software.
I used my vodafone simcard with Galaxy Core (another dual sim phones), and they seem to work fine,
which gets me all the more confused.
The only difference that I notice is in the Mobile Network Type.
Its EDGE:2 for Vodafone and UMTS:3 for Idea, wonder if this has got anything to do with the network issues.
I did the default available 2 firmware upgrades since purchase, they seem to have worsened the problems.
Let me know if you are facing the same issue, with the same service provider.
Need to keep a close watch on the solution, as it seems to be affecting more people than expected, surprisingly couldn't find any issues a month back during the time of purchase....
Regards,
Varun

In my case, it's Vodafone also, but is in Western Europe.
My concern is that i have exactily the same problem in my present phone (Sony Tipo Dual) and it's the main reason (along side the big improve of speed and etc) for buying this phone. At the present, people call to me and they say that phone answers occupied (no network signal) and i look to the phone and it shows top signal strenght. I'm beginning to think that dual sim phones with android have some limitations (maybe antenna limitations).

thats true it should never occur, i think its implementation problem, android its not mean to be for dual sim phones the solution for dual sim on android its a samsung workarround, it should not be buggy but has some problems it does not make the phone unusable for me, I don't get coverage all the time, I travel from city to city and get poor coverage all the way so i think its not a big issue since it happen just a few times.

Hi Sriram,
My problem is very similar, Vodafone on either sim slots gives network problems, and Idea on either sim slots works fine. That makes me think that the problem must be hardware / software related to Network type. Its EDGE2 for vodafone and GPRS1 for Idea. What is the network type of your sim cards?

Surprisingly the issue is only with Vodafone, where the signal after dropping (very frequently) does not refresh.
In case of Idea simcard, the signal refresh is working fine.
I am not able to understand if the problem is with the service provider, sim card, hardware or the software.

Hi Sriram,
My problem is very similar, Vodafone on either sim slots gives network problems, and Idea on either sim slots works fine. That makes me think that the problem must be hardware / software related to Network type. Its EDGE2 for vodafone and GPRS1 for Idea

I use idea in the first slot and BSNL in the second slot. The trouble occurs with BOTH SIM. Earlier I used idea -Vodafone pair, the problem was still there. I live in am area where all operators have weak/varying coverage. Airtel and aircel have already been reported as showing same problem. All the users are affected with this issue, so it is clear that this has nothing to do with the operator, it is a fault of the phone either hardware or software. I think you have idea Sim working fine only means idea network is better in your area and may not need frequent network cell changeover. (?) And another fact we can see from the reports is, that, almost ALL THE COMPLAINTS have been reported from INDIA where the model released is the duos.
S4 Mini Network issues.
I too have a S4 Mini for less than a month and I am also facing network issues. One thing to notice is that the sim with internet doesn't have issues. Irrespective of which slot it is in. Currently I have Vodafone IN on Sim 1 and Airtel on 2 (with 3G). Airtel works fine and Voda has issues.
I did speak to Samsung care, they were very nice, however the problem wasn't solved, I have been adviced to go to Samsung service center and get the S/w reimaged.
I still haven't done that, however what I did was to reset the phone and while I was browsing on the play store I got a software called "Where is my Signal" by Grey Boy. For some reason I feel it is working fine now. I have not had any issue from last evening, baring one time when I was on a long conf call for around 150 mins today. else it has been working fine and receiving calls on both sims too.
I had used this software to refresh the network once, it has helped me, not sure if this is going to sustain but for now it is good.
If some one else also has this software installed and is finding this to solve the issues kindly post the same on the forum and may be helpful.
Will repost tomorrow again with the status.
BTW I agree to many opinions in this thread that Samsung should have done some testing or atleast after many of these issues coming up needed to provide a patch upgrade.

Will factory reset work?

I had tried three apps of that kind: where is my signal, network booster(marcstealth), and network refresher lite. None of them could overcome the strange problem of this phone though at first they seemed to be working. Another question is, how do we know when to refresh network? If we know the signal is lost, we can restart or do something like that. Then there is one more issue: sometimes it shows good/full signal strength, but when try to make a call, will realize that it was false! I made to run the network booster app run when signal is low, using tasker app -but we are not supposed to live such a life using this celebrated costly handset.
But one thing in your post is of much importance. DID THAT RESET WORK? You haven't said much about that.

The reason for reset was to ensure that none of the softwares I had installed were causing the issue. The reset didn't change much compared to the way it was earlier.
Some observations of when the problem actually happens (again this is my observation and doesn't need to be the same in your case)
> When I am on a long incoming call on the sim which has Internet.
> Noticed that short calls don't impact the network.
> If there is a call drop imm after you receive a call.
I am planning to get the phone firmware re-imaged from the service center however I will need atleast 10 more days to do it as I am currently in a different city and I am not carrying the invoice copy.
BTW Rajesh, did u get any response from the CEOs office?

On Verizon, will it work and any links for this specific version?

Hi guys. I've been a member of XDA for some time through many phones rooting, ROMing, etc., and customizing many phones. But I haven't done anything for awhile, still rocking the Note 4, and am by far no expert. I am really looking to get my hands on the Xiaomi Mi Max 4GB 128GB dark grey version. I've never bought a phone that wasn't compatible or made for my carrier, so I need some help.
1. Does anyone know if they will get these back in stock, or am I stuck purchasing a gold one?
2. I am on Verizon. From my understanding, it will work except LTE. Do you still get 4G but not LTE? Is it a huge deal really? Can you still stream on Netflix etc, without a huge lag? I've read from some users online it wasn't a huge difference.
3. Which version do I look for, International?
4. Would it work better on AT&T? Because I am willing to switch for the phone I want. If it's the same as Verizon, no LTE, then I'll just stay with Verizon.
Thanks for any help guys. I really want this phone. I was disappointed the Note 7 is still so small. The Note 4 easily fits in my pockets, so I can't see why they won't go bigger with all the use of media and internet these days. I know some people wear skinny jeans and already have an issue with the size, but that's why they have other options like the S7.
Also looking into the Asus Zenfone 3 Ultra. Will that work any better on a US network?
I'll pay you $1,000,000 if you can get Verizon to activate this phone on their network. They would never let you use any of these phones on their network.

They block it from accessing their network. They limit what's allowed to run on their network. I even tried my friends Verizon sim in my Mediapad X2 and Mate 8 and nope, if it's not in their whitelist it won't work. That's one of the main reasons I left Verizon a while back.
Ok, few important things to share with you.
Consider the 32gb, 3 gig ram version because it has the most development, global ROM, and possibly lower cost. I'm seduced by bigger specs models but frustrated to no end by lack of global ROM, I've got the 64 gig.
Secondly I ditched Verizon for this very reason. Lack of open network and hassles getting devices to work.
Thirdly, look at network coverage in your area, pick the better of AT&T or T-Mobile. I've gone with T-Mobile and not looked back. Speeds are good enough at H+.
Finally, Lenovo Phab Tango device with US LTE bands is about to hit the market, so research that also. ?

THANK YOU so much!!! That was awesome information. Lenovo Phab 2 Pro, seems to be the only fairly current phone over 6.3" fully compatible in the US right? I've had so many cell phones over the last 15+ years, more than 15. I've never cracked a screen. But with having such a larger screen, it concerns me a little I have not seen anything about it being Gorilla glass. Other than that I'm sold. Not that there are many choices in that size compatible in the US, but it has pretty good specs overall. I only wish for a little bigger battery and Gorilla glass. But you sold me sir. I'll be waiting for this. Guess I'll be switching to AT&T soon. Thanks!
I have the data and sms/mms working on Verizon currently. Did all the troubleshooting with them and on my own. Not your typical customer, 32 years in technology network engineering. Been fighting with them to have it added to their system. Finally someone submitted the form for me waiting to see. As for now I have my Verizon number forwarded to my Google Voice.

Mi max 3 losing LTE on tmobile

I've been using the mi max 3 on tmobile since the beginning of September. Have loved it, big screen, huge battery, good camera. But in the past week I've noticed at work my LTE randomly dropping while at work. I've been using it with strong signal just fine up to this point but now while in my pocket the LTE dies and I'm on what seem to be edge speeds.
I factory reset the phone, and within a day the problem reappeared with only a half dozen apps installed. I was able to restore LTE intermittently by toggling airplane mode on for a half minute then off, but now even this doesn't work. I know there's band 4 coverage where I work. Does anyone have any troubleshooting ideas?

Do you have Prefer LTE selected on your Preferred Network Type in your sim settings for your current sim?
I do. I've tried swapping from the default apn (the one displayed in one of the accompanying pictures) to another and back, which also sometimes fixes the issue. Finally I've tried deselecting select networks automatically which makes it reaqcuire LTE randomly. However all of these fixes fail to provide reliable results, and often I find when I take my phone out on a break after it being in my pocket for awhile I'm looking at no LTE.
Edit: I've tried the one more straightforward fix by switching from sim slot 2 (with an SD card in the hybrid slot 1) to no SD card with the sim in slot 1. I can't see this being relevant but grasping at straws to keep from going back to my mi mix. Love that phone and all but this battery is too good to pass up if I can help it.

Try enabling volte. Not sure if it might help, but try anyway. Dial *#*#86583#*#* in your dialer.
Also already enabled. I'm not sure if it's because I have the Chinese rom but it displays as "HD" above the cellular bars, rather than volte, even though my mix on miui 10 just displays volte.
Try checking cellmaper ( https://www.cellmapper.net/Index ) to see if the T Mobile tower near your office has been moved. It's very common for the big carriers to rent space on suitable structures for their equipment rather than owning the towers outright. When leasing arrangements are up for renewal, a carrier may choose to move to a competing tower owner. That happened to me on AT&T. They had equipment on one tower to serve 2 small communities and chose to relocate farther away from both communities. There was no notice, just a very weak or non-existent cell signal. Customer service seemed to take a back seat to reducing costs, even though those costs were a valid business expense and tax deductible. US businesses just don't see value in customer goodwill in this era of courts only protecting stockholders.

I suppose this is an outcome I might have to accept. It's frustrating, because I went around with my prior phone double checking what the dominant LTE band in use was in my area, but there's little to be done for it. I wish the US had better selections for domestic offerings.

Question Returning due to connectivity issues. Past return window too.

I already had to have a defective screen replaced but now I more times than not have no signal. My OnePlus 7t has full signal strength. I'm missing calls and it's unacceptable. I'm never purchasing another Google phone again. I should have learned my lesson with the Nexus 6p. They will be emailing me with return instructions within the next day. I demanded a remedy or a full refund and they obviously have zero remedies as it's apparent the cheap Samsung modem they used is likely the cause. I tried all the potential from fixes but nothing works and I shouldn't have to disable 2g or downgrade to lte. So disappointed with Google. Think I'll stick with my 7T until something better comes out. Maybe I'll go with the M11 Ultra.

Sorry for your bad experience. My P6P has about 15% better reception and 20% better DL speeds than my Note 20 Ultra so I can't imagine it would be the modem since they are probably the same.

Glad you aren't experiencing this issue but it seems to be a mass issue and Google has been completely silent. I don't trust them after what I went through with the Nexus 6p which resulted in a class action suit settlement. I sense this phone will follow the same path too.

TMobile. In the Phoenix metro area. Going to a TMobile store now to get a new sim card. Doubt it will help but we'll see.
I just returned from TMobile. New sim card. No change. They didn't charge me since it made no improvement. Sorry, phone is junk. Never getting another Google phone again. Never.

@Starzboy77 - yikes! i had a similar problem with an AT&T P6P, when using an eSim and nano Sim (tried 4 eSims). the phone wouldn't hold a signal so i returned it to the store. the one thing i didn't try was forcing the phone to use a 4G/LTE signal (supposedly fixes some connection issues). thanks for taking time to respond to my questions.
Yea, on VZ in the Cleveland area I am dropping signal also. Never dropped with my 3XL or my Note 20.
Driving across the turnpike going to Michigan it dropped multiple times. The turnpike is rocl solid coverage. They added towers years ago to be sure it was solid end to end.
This phone is going to be a nightmare to use when the snow is gone and I start traveling on my motorcycle. I suspect I will replace it before then unless there is a software fix. This modem is junk.

No. The 6p had a bad mic issue and a bad battery issue that would lead to shutdowns while still reading at 40% power. It also had bootloop issues that were related to the board I believe. It was plagued with problems which the Pixel 6 Pro seems to be matching. Connectivity, overheating, Bluetooth, battery to name a few and my first one came with a screen defect that required a screen replacement.

I can only guess that those problems are imaginary or due to some weird garbage you installed. I took mine off the charger on Friday morning. Currently at 25%. Battery life and obviously heat are non-issues. Bluetooth works perfectly.

My issue with the 6p was the bad battery. Mic was fine.
Connectivity was the worst for me with TMobile, download speed of less than 1mbps, calls and texts were bad, after a decade of loyalty i ditched them, went to at&t and all good, only problem i have with this phone is the screen not responding to touch for a few seconds a few times a day
I sent mine back to be repaired mic didn't work at all. I sure hope they send me a new phone and not split it open
I have been hesitant to say there's connectivity issues on the P6P. However, my experience hasn't been great. Compared to my P4a5g, signals are similarly weird but I get more bars consistently on the P4a5g.
Disclaimer: I straddle weak 5g and LTE signals in almost dead center of SF.
Even turning off 5g to eliminate the terrible handoff to LTE, I bounce between LTE bands on each end of our flat.
I have to be right in the middle of a strong signal area to get full bars with the P6P; consistent 5g is elusive.
Maybe it is time to look at other carriers? I have been with TMo since 1999. Seriously.
Would love to hear from anyone in SF on their carrier experiences. Have always avoided Verizon and AT&T. What about Google Fi?
My sim card is ~4-5 years old. I should get a new one. Is eSim better for signal?

I mean I think we're pretty lucky in North America because we get to choose from 3 providers instead of one (the more the better for sure). I'm not in SF but I know that sometimes, changing cell providers can make a world of difference. even in cities. different towers from different companies use different bands. it can make such a difference. a good start is a new SIM card for sure. I suggest people get a new one every 5 years.
some providers might also give you a 2 day trial, maybe look at that option? (they do in CA).
@Alekos thank you for the feedback.
Since the P6P supports eSim, testing other providers should be easy, right? I am guessing that using eSim doesn't make a difference in network connectivity performance. If you understand otherwise, please let me know.
And yes. I will definitely get a new sim. Can't hurt; might help.
Thanks again.

The same thing was happening to me about 2 months ago on both of my Poco F3's right before I got the 6 Pro. It ended up being something with T-Mobile as the problem stopped about a week and a half later.
