[Q] Strange icon in notification area...

I have an unlocked at&t phone on tmobile's network. just got it today. it's completely stock except for the fact that it's unlocked. and i'm fully aware that this is an at&t forum, but the phone for all intents and purposes is built by/for at&t.
there's an icon in my notification area that says "t-mobile" (pictured). anyone know why this occurs?? when i pull down the notification area, there is nothing that corresponds to this icon. it's taking up too much space for absolutely no (discernible) reason.

Why does it say "edge" beside T-Mobile with little data bars, if you're connected to WiFi?

It's telling you which network you're logged into. With an AT&T sim in, it would say AT&T up there. This is not terribly useful when you're on your home network but indispensable when you're roaming abroad. Many networks have roaming partners, so, if you were in Italy for example, you may find that being on WIND was about 10% of the price than being on VODAFONE. Also, if you're near a border area, you really don't want it roaming onto a foreign network when it could be using your local one.
The stock touchwiz roms have this up on the top left. CM based roms tend to just have it on the lock screen (from what I can tell).
TMobile has a different 3g frequency setup than AT&T which is why your phone is using Edge (2g+). I saw a way on the these forums to unlock the AWS band which may be worth looking at.

this is all outstanding information. thank you! i was definitely getting annoyed that it was edging instead of 3ging when im not directly in 4g spaces. and knowing that this is part of touchwiz, i intend to CM it so it should hopefully go away.
i'll defnitely look into unlocking the band. didn't know this would be an issue when i got the phone. awesome info!!

Awful LTE signal after update

I have an unlocked 10 running on T-Mobile US. I previously had no problems at home with a 4G LTE connection. But after updating to 1.53.617.5 this week, my LTE signal at home has completely disappeared on me. What's worse, the phone shows full bars, and won't drop to a slower connection. I have to manually switch to 4G/WCDMA (Auto) and use the slower 4G connection, which I presume is HSDPA.
Is anyone else experiencing the same problem? I even did a factory reset, but it didn't help whatsoever.
Between this and the weak Wi-Fi, I'm starting to have second thoughts about this phone.

My LTE and wifi signal are slightly weaker on the 10 than what I'm used to seeing. Also on Tmo US. My LTE drops when I'm not upstairs lol. I took the ota when I first started up the phone so I can't speak for the other version.

Does it stay on LTE even though you have no reception? Mine does, and it also shows full bars.

Maybe try wiping the cache partition? Check the "weak Wi-Fi signal" thread for directions on how to perform it. Just a suggestion.

I just tried wiping the cache partition. No dice.
I installed the OpenSignal app to see what's going on. It seems that the phone is locking onto a cell tower that's many miles away (in the middle of a river!), instead of many LTE cell towers that are only a block away from me. This makes no sense. It also indicates full reception.
The latest update definitely messed something up. Perhaps it's related to the "Wi-Fi stability enhancements".

I have this problem as well, spoke to T-Mobile and of course they tried to blame it on the phone saying that they cannot guarantee that an unlocked phone will work with their network. I proceeded to tell them that the phone was listed as fully compatible with T-Mobile's LTE network they had no answer. I know it's not a solution at all but I'm on T-Mobile's prepaid service so at the beginning of next month just before I need to make a payment I'm switching to AT&T to see if that is any better
I'm somewhat disappointed and I really don't know if I should return the phone or not

While I do think the 10 doesn't get a signal as strongly as other phones do (my S6 was great), I think the latest firmware (1.53) has impacted reception for the worse.

I shouldn't have to flash the phone to get it to work. Also, the purpose of getting the unlocked version was to have a carrier-free phone.
The more I use this phone, the more I notice that LTE connectivity is screwed up. It likes to lock onto the wrong cell towers that offer no reception (but still display full bars).
What's interesting is that when I turn on Wi-Fi, the phone locks onto the correct cell towers.
Forget the camera; HTC needs to resolve all these radio connectivity issues!

I agree the purpose of getting the unlocked phone was to not have to have a carrier branded device. I noticed that as well with the phone connecting to be incorrect tower. It really is frustrating because I've already started paying for my phone so I don't want to have to return it, I like all aspects of it physically but something has to be done about this reception. I used to get 4 to 5 bars and now I'm lucky if I get two

This is really ridiculous, I've only had my phone off the charger for just over an hour and I've used 10% of battery. I don't keep Wi-Fi on all the time I only had to turn it on to use Wi-Fi calling because my signal is so bad, HTC really needs to do something with the radios in this phone because the poor cell signal is just killing my battery life. Is anybody experiencing this same problem?

Root your phone and then install better battery stats or gsam or any other utility that can show you specific wakelock stats and info. From there you can use that info to track down the specific wakelock.

Anyone has VoLTE on EE or Three UK?

Live in Edinburgh and just got my OP3. After put Three and EE sim cards into phone, I can't find "enhanced LTE" option in the setting menu. Does it means that VoLTE is not supported on EE and Three?

Yes, I can confirm that VoLTE and WiFi calling doesn't work on EE.
On Three you can probably use their app for VoLTE and WiFi calling (if you are not rooted).

Hi there. I can connect to the 800MHz LTE on the Three network, however there is no option for me to use native VoLTE or VoLTE via their InTouch app at all.
I doubt we'll see VoLTE natively on this device, but there may be a chance that a future update to inTouch would let it work there, but damn I hate their app.

Or use the dialer and use *#*#4636#*#* to view additional signal information.
It's somewhat of a guessing game also. I only get LTE signal here if its 800MHz as they recently rolled it out.

I have LTE on Three, but not VoLTE.
I also hate their awful app.

I'm trying to get VoLTE working with 3 on my OP3 too. From what I can tell, we need the APN settings for the 3 IMS APN. Damned if I can find these listed anywhere though. If somebody has an official 3 phone with working VoLTE then we can copy it off there.
I'm wondering if the Enhanced 4G voice option will show in settings when a compatible APN is detected? Other people seem to have VoLTE working on their OP3 (looking at posts on xda), but I'm not sure if they're using the stock rom or not.

The issue is that EE/Three really have no incentive to support the OP3 because they don't sell it.

Same goes for all UK networks none of them will enable VoLTE on the OnePlus 3

Just want to bump this thread as 3G coverage is rubbish around my home area. For some reason I only get 4G and am not able to get 3G. I have to use the Three In touch app to even receive calls

I'm interested too. My wife and I are both on three UK. She gets VoLTE on her Xiaomi Mi5 Pro but I don't see any options at all on my OP3

How do you get VoLTE on that? According to gsmarena it doesn't support band 20, and as far as I know Three only has VoLTE on band 20? It would be interesting if you could let me know if a) Three are now running VoLTE on band 3 too, or b) It actually does support band 20. Here's the gsmarena page: http://www.gsmarena.com/xiaomi_mi_5-6948.php
Thanks!

I've no idea. We were just sat in a pub and she asked me what the VoLTE in the status bar meant. Sure enough the icon was there and she gets it quite often

If you're on EE you probably won't get VoLTE; they're having trouble supporting the S7 so the OnePlus 3 is pretty much a lost cause. I know that kinda sucks for you guys on the better performing network
Three are more likely to; they support a lot more phones on VoLTE and are generally a lot more Android friendly than EE (EE always release Android updates very late, and everything is given to iPhones first).
But I'm obviously just guessing here, until VoLTE is more mature in the UK it's likely VoLTE support will be the complete mess it is now with only major phones getting it.
Hope that helped

why would you want 3g if you can get 4g ?

Last time I checked with Three they told me that only some phones approved/sold by them support VoLTE.
A few months ago they whitelisted the Oneplus 2 to use VoLTE though their app. The Oneplus 3 is not supported yet (not sure if it will be in the future).

Sorry. If you don't know voLTE (on the three network) only works on 800mhz, which only works on 3 carrier bought phones. 3G is the only way you can call apart from that, and as I already said, my area does not have 3G coverage.

4g calling now works on 3.5.2 on EE

I've tried that. Seems to me like a problem with default band settings.
In the build.prop it's set to:
ro.telephony.default_network=20,20
Which is asia lte/td-scdma; if i knew how to change it to ro.telephony.default_network=9
i think that would fix it.
For now i'm just waiting for someone to release some baseband versions to flash.

That's not good hopefully get mine in a few days and i'll report back. I had previous phone like Zuk Z2 that had similar bands but work with both LTE and calling/sms no issues.

I and a friend have noticed these same issues it must be android one issue.
I did post in another thread about poor signal on different networks and how it compared to redmi note 2 which doesn't even support a lot of the bands this phone does yet that has far better signal.
My friend doesn't even get signal in his house on o2/ee with this phone it keeps showing up as emergency services only but with redmi note 2 he gets max with o2 on 2g/3g and ee it hops about with half bar for 2g/3g and quater to 0 on 4g in the house.

Seems to work fine for me. I have 4G on and calls come through just fine. Might be a location issue but I'm on Tmobile and in SoCal

Yeah LTE data works great but no calls go through , and there are no GSM antennas near by.

Same issue with my Mi A2 on T-Mobile in the US. I even contacted TMobile about the issue because it seems like a network issue too. It's like it's having issues switching to 3G to accept the call as there is no voLTE. I'm hoping an update to the modem will fix the issue.

AT&T tech support said my OP7T not LTE Compatible

It's HD1907 T-MOBILE. What I need is HD1905. He sent me the wrong one.
I only realized a few hours ago I had no mobile data. I had got calls and texts to work this morning.
After spending 45 minutes on the phone with AT&T they concluded my phone is not recognized as LTE compatible. WTF? It's not even connecting to 3g.lb
I've been buying unlocked phones for years. My last phone was OP5T. I've never experienced anything like this.
I'll probably take it to the corporate store tomorrow but doubt it'll help. Has anyone had problems with AT&T and this phone?
I'm just putting it out there, hoping somebody has an idea...

AT&T worked for me, excellent data speeds, and great signal. But at times it would go from 4 bars to absolutely no signal or data, and lots of dropped calls. After that I went to Verizon, not as good of signal, slower data, but no dropped phone calls or mysterious total loss of signal in an area where it should have been 4 bars.

I'll bet if you look in the settings your model is HD1905 or the global model, not sure the number.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

Anyway it's BS. If the carrier supports the phone, and the phone is capable of VOLT!/WIFI CALLING, it should work.

Yes Verizon. I have heard hear many times on this site, that phones are blocked from wifi calling by the IMEI, I or they could be wrong.
Vowifi works on the unlocked Pixel, but are they going to butt heads with Google? Volte works fine, I got a network extender, and I can use google voice to make calls over wifi if I really need to.
If vowifi is a must, get an approved phone, that is all you can do.

I worked at AT&T until a few months ago. I can tell you confidently that their tech support is a bunch of dummies. Employees have their own tech support line to call and that one is just as bad. They would routinely tell customers they needed to go to a store to have something done. Then they'd get to the store to find out we literally cannot do that at the store. Stuff like that was super common. One of them even bet me $1,000 that iPhones DON'T reboot when they update, which we all know is all the way wrong.
I halfway think support tells people that stuff on purpose to try to get them to buy something from AT&T. God, I could rant about that place for hours lol

Maybe you can answer this for me. Just because a T-MOBILE locked phone is able to make calls and texts on AT&T, does that automatically mean it should be able to connect to mobile data?
I was able to get it to make calls after a refresh signal was sent out, but it could not connect to mobile data . My sim is fine. I even popped it my son's Pixel 3a and LTE started immediately.
The seller is saying the fact that it was able to make calls means it is able to connect to mobile data. And I should take it to AT&T before returning it. I don't think he's scamming. He says he has the same phone on AT&T. And he's sold Hundreds of them. That kinda checks out based on reviews and some of those people do report it works with AT&T.
These phones are hd1907 T-Mobile but supposedly OnePlus unlocks them before sending them out to some sellers. I sort of believe the guy but is it true? If it were locked to T-Mobile could I get it to make phone calls?
Obviously I'm not talking about a hack. Because I thought locked was locked. Is it possible for a locked T-Mobile phone to make calls on the AT&T network?
Also I got AT&T to make it work but once I removed the sim/reinsert it, the thing displays weird behavior. Wifi goes in and out. It forgets the apn settings that were set prior.

I worked at AT&T until a few months ago. I can tell you confidently that their tech support is a bunch of dummies. Employees have their own tech support line to call and that one is just as bad. They would routinely tell customers they needed to go to a store to have something done. Then they'd get to the store to find out we literally cannot do that at the store. Stuff like that was super common. One of them even bet me $1,000 that iPhones DON'T reboot when they update, which we all know is all the way wrong.
I halfway think support tells people that stuff on purpose to try to get them to buy something from AT&T. God, I could rant about that place for hours lol

I agree, ATT was the most horrible experience I ever had. Tracfone may have even had a better customer support.
Verizon CDMA service may be antiquated, but their customer service and tech support is 2nd to none.

Maybe you can answer this for me. Just because a T-MOBILE locked phone is able to make calls and texts on AT&T, does that automatically mean it should be able to connect to mobile data?

It should have no trouble using data BUT you'll have to change the phone's APN settings to match your carrier before you can. You can google it and find them. It's not hard at all to change. Somewhere under the "network" settings.
Someone correct me if I'm wrong, but as I've understood it the phone will keep trying to access the previous carrier's data network, which is why you didn't have data. But as said above the APN settings should fix that.

If I told you the whole story, which started on Friday morning and in the end involved 7 AT&T employees, 6 on the phone and 1 in the store, it'd probably be removed because it's spam. Too long of a story.
But in the end it didn't get to connect to mobile data..at least not consistently. I took it to the store. The guy removed the Sim reset it, turned it off and boom! - LTE, calls and texts. His theory was it takes a little while for it to unlock and get set so when I tried it the other night it wasn't working.
I was happy because it literally took 5 minutes. I ran some errands and was out for like another 2 hours. Everything was working. Some point between the store and my driveway, the signal was gone. I never got it back. Of course I tried reset, remove Sim, reboot, change apn settings.
I called AT&T... the first woman didn't even know what CDMA and GSM was. I politely got her to transfer me to the guy who 'knows his stuff'. He got it to make calls again, but in the end concluded this device can't work on this network. I didn't wanna argue anymore. He had a BS answer for everything including 'If it doesn't work, why DID it work just a half hour ago?'
He said I could try getting a new sim. They have no idea. My son's sim won't work on this phone but pop it in my old phone and it works. And my sim works in his phone. It's not the sim. I know it.

It's HD1907 T-MOBILE. What I need is HD1905. He sent me the wrong one.
I only realized a few hours ago I had no mobile data. I had got calls and texts to work this morning.
After spending 45 minutes on the phone with AT&T they concluded my phone is not recognized as LTE compatible. WTF? It's not even connecting to 3g.lb
I've been buying unlocked phones for years. My last phone was OP5T. I've never experienced anything like this.
I'll probably take it to the corporate store tomorrow but doubt it'll help. Has anyone had problems with AT&T and this phone?
I'm just putting it out there, hoping somebody has an idea...

I took it back to AT&T yesterday. There was someone in front of me so I sat down, removed the sim from my working phone, popped it in the op7t... instant lte, calls & texts. The same thing happened the day before I went to at&t. It worked perfectly well there in the store and even 2 towns away but not m my neighborhood which DOES connect to LTE, has for years on every phone we've had.
The tech (if you can really call him that) updated the sim. That got it done. I've had a working phone for 24 hours. BUT no LTE. It only connects to H+.
I haven't had time to call or go back to the store, but I'm hoping it's an easy fix. This has been the weirdest week I've ever had dealing with a phone. I've learned that AT&T doesn't know what they're doing. I still can't believe I needed to explain what GSM and CDMA was to one of the people on the call.
I'm gonna try a few things tonight after work.

Thanks for sharing, but I've never really needed to mess around with the settings as far as mobile data goes. It either works out of the box, or at most I'll need to put the apn in manually on some custom roms, but even that's rare.
How does the info you provided apply to my problem. I know the phone can connect to lte. It was connecting briefly on Monday afternoon and while I was at At&T yesterday, it connected before they updated the sim.
Is there something I can do with this? It's a sincere question. I'm not sure if I can apply it somehow. Thanks

I think his point was to show that the OP7T does in fact work on all AT&T bands. Normally you don't need to do anything with this if the SIM is provisioned correctly.
What are the chances that you are on the edge of the local AT&T LTE signal so it drops to H+ because that's a stronger connection? At the AT&T store the LTE signal is stronger so the phone is favoring that one. Some phones are more sensitive to signals than others (or more aggressive at switching to a stronger band).
Try using a program like "LTE Discovery" and see what bands you actually are connecting to. It can also let you know what is going on in your area with tower location.

I'll try that. Thanks.
That's what I said but the guy at the store said it's really not a stronger signal at the store. Plus I know I can get LTE at my house and in the store because all our other phones connect, even this one, briefly at the at&t store.
The seller have me a code to input into the dialer but I'm waiting for tomorrow to put it in. It's my day off. If something goes wrong it won't be a huge deal. I will look into what you sent at some point though.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

Your posts are bouncing between VoLTE & VoWiFi.
LTE bands and VoLTE work fine on Verizon's network.
Verizon allows VoWiFi on the OP 8's that they sell. They will not activate VoWiFi on the OP 7 series, the claim is that the phone did not go through their security testing. IIRC VZW doesn't allow VoWiFi on any outside phone.
