For me, a similar problem
Setting the network mode to auto or just wdcma makes the phone unusable.
Although the extent of the phone grabs. Nay, sometimes even 5 bars but the state does not tra large than 5 (sometimes 10) minutes and reach lost. Often with good coverage, I can not make calls and the internet does not work. Redials the phone ends in the subscriber information out of reach (the phone shows that he has range)
Switching the phone on GSM ONLY mode causes that everything starts to work as it should (only the net so slow)
The problem started a week ago
The problem occurs in various parts of the city, regardless of whether I use the transmitter Play network or roaming.
Factory reset did not help. I suspect the SIM card but the more I'm bending your point defect (eg antenna) since the last few months everything worked
EDIT:
1h watched by telephone yesterday, and what I noticed.
The problem is when a weak signal mode UMTS.
The signal strength of -90,-95dBm causes the phone to have problems. If the signal is below-100dBm the phone is able to maintain a dial-up connection to the Internet are no longer problems. Often there are also decreases above 100dBm signal which usually end up losing the connection of both GSM as well as internet and phone needs a few dozen seconds to reconnect.
If you set the mode to GSM only signal strength is-55dBm and the problems do not occur.

it's your network providers problem not our's. you can obviously not get 3G all around your city
Can't do speedtest (Network Communication Issues--TRY AGAIN)
Can't browse the internet (Unable to connect)
Can't play internet games ( Dragonplay poker,etc...)
Ok, this happens every now and then even when I have 4g with all my bars mainly when I get to work and starts back working maybe 1hr or 2hrs later (when I'm home I mostly use wifi but my mobile/gps works). I try to test it by trying to see my speed on the speedtest app but does nothing. Even tried the "faster fix" method and it doesn't work. Tried the S3 method with tightening the screws but they were already tight. Cleared AGPS and updated AGPS, loads up 20 something in use and finds GPS but still not working.
My area doesn't have LTE yet but the surrounding areas (mainly 2 hrs away has it). Call Tmo but hell they don't know if there doing any work in my area or not. Just kind of strange..I been here at work for 3 hrs now and haven't start up yet but still showing 4g with 2 bars now. Yesterday it took about 1hr maybe, then boom starts working (playing games, browsing, speedtest). Just trying to see has anyone else came across this issue and fixed it. I also read other users returning the phone to get another and only to find out it happens on it the new one too. Not sure if its a hardware issue or software cause verzion, att, and sprint also has this issue
Phone is rooted and have Alpha 5 with baseband MDL. APN seems to be like every other TMO US LTE (fast.t-mobile.com and other settings). Network Mode: LTE/GSM/WCDMA (auto connect) selected..GPS on Mobile on...
I was originally a Verizon user so I'm not used to this kind of weak connection.
I had my phone replaced already due to another issue a few weeks ago
so I don't want to get another replacement because of this. it is really annoying!
Instead I will ask here and see if anyone could help !
**This has nothing to do with WiFi (because WiFi works great!)**
**And nothing to do with calls because call quality and connection showed no problems**
**Not exactly sure this problem started, just started getting annoyed with it recently**
\- What my phone is doing (when I'm at home) -/
1. Slow transition from WiFi connection
- When I turn Wifi off, I don't get an immediate data reception. Instead it takes about 10 seconds and then I barely start to get 3g..... not lte .... (It's not like this in every place)
2. Not much LTE
- It happens really rarely, most of the time at home the connection is on 3g
3. Lose data connection even while in use
- It's just sometimes unstable. When I'm browsing the web (while in 3g) it would sometimes go down to no bars at all and lose internet connectivity, then the 3g and I have to wait again until it comes back.
- Data roaming automatically turns on saying that I lost connection -_-
4. 3g is sometimes really unresponsive
- Just like when it is when turning off Wifi
- 3g would stay idle for sometime, even when I open apps that require internet
- Sometimes the 3g just disappears and decides not to comeback for a while
5. Bars up and down (drains battery?)
- I see this too often, like in every hour. While in 3g, the bars get suddenly full, then in an instant it drops to 1, then to 2. Then sometimes to no bars at all.
* in LTE it never gets like this, just constantly 1 bar
6. Maybe it's where I live?
- Possibly, but it's quite an urban and Sprint should have no problem covering this area in my opinion
- Verizon wasn't like this (although not perfect)
7. This is annoying
-Because it is draining the battery -_-
-Because my sister's iPhone 6 performs better (always has 2~3 bars) & my brother's S6 (though relatively weaker than her's) does not seem to lose connection compared mine at home (We're all Sprint users)
\- What I've done to confront this problem -/
1) Called Sprint, but didn't help at all. They told me to just take it to the store and have them take a look -__- Agent hardly knew anything...
2) Flashed Stock ROM and hard reset the phone (so annoying since you have to set things up again)
3) Made sure I set mobile data Network Mode to 'AUTOMATIC'
4) Made sure I have the latest Software version and have the PRL and Profile updated
But still no result at this point.
***Could this be a hardware issue? Or a software issue that is fixable?***
Can anyone give me some advice on how to fix this?
I mean it's just that the data reception is too weak an unreliable to think this is okay.
Right now my phone is pretty empty, barely any apps because of the reset.
I really don't want to believe it's due to a faulty hardware!
P.S. Possibly symptom?
The first day I got this phone as a replacement out of the store, I was unable to connect to the internet using data, even though calling was working.
What it was doing was, constantly switching from 3g - lte - inactive 3g - nothing - 3g - so on in a 20 second cycle.
By the end of that day towards midnight it was connecting to the internet.
Welcome to Sprint -_____- my GF has 4G LTE on Verizon where I live and I don't even have 3G, I roam on Verizon actually lol. Sprint literally has ZERO coverage while Verizon has LTE.. It's just Sprint dude lol.
I'm hoping someone has seen this and knows the solution.
I have a Pixel 3XL, bought Nov.`18. Unit has a case, never dropped outside, it's in immaculate condition.
A few weeks ago, I noticed the LTE Connection would restart every 8 to 12 seconds (going from LTE - LTE+, back to LTE)
I did a ton of things (restarted device, safe mode, Factory Reset with stock setup (no backup) and even did a Factory Image restore of Android 10 from September)
Nothing has resolved this issue. The case has been removed, a different SIM Card was purchased.
Even when changing the connection to 3G, it changes from HSPA - to 3G every 10-15 seconds. I've disabled VoLTE and even used the phone after factory image restore, with a new google account (to make sure no settings were copied over from previous install). Checked APN settings, all good there. I've had every PIXEL phone on my carrier (Rogers, in Toronto) without any issues like this.
At this point, I am thinking hardware.,
Does anyone have any insight into why this would just start randomly in November?

Mine and now my pixel 4 have a similar issue. But it seems to randomly drop to 3G and get stuck until I put it in airplane mode and take it out...

Take a SIM Card from a different Carrier, see what happens. That will show if its Hardware, if it keeps happening.
Mine had the LTE connection reset every 10 seconds no matter what SIM Card I used from different carriers.
I got a replacement Pixel3XL today, and the new unit is working perfectly - so it was hardware 100% on my end.
Just curious if anyone else has had any issues with WiFi calling on their S20 variants. I have a stock S20 Ultra on Verizon. I recently noticed my wifi calling would simply just not connect at all. It was also failing on sending some text messages, problems that I surmised might have been a recent wonky app installed. I then factory-refreshed the phone from scratch, and installed from scratch, manually picking and choosing my apps to avoid the same fate. But even so, my WiFI calling is sporadic at best. Incoming calls will ring in mostly, but if I answer the call, I get no sound at all and no one can hear me. Outgoing almost never works, unless I restart the phone, then toggle wifi calling off, wait a minute, turn it back on, and then wait for the icon to display as WiFi Calling able. Then I can get one call out. I can immediately hang up and try again, any number, and it'll just sit there waiting to connect. I have only been able to test it while on my home network. I did also recently upgrade to 50m Fiber internet, though everything is routed through a Google OnHub router for wireless so I can monitor devices in the home. I'm still connecting to the same band that I was prior, and that my other phones (my S105G and S9+) have had no issues connecting and calling from. I do not have a strong enough signal inside the house for calls to connect over the network, so that's out. All other data on the phone works fine from wifi. Texts work more reliably but still suffer from the occasional Sending Error where it times out and I have to resend. Or it'll take an extra 20-30 seconds before it sends. I get the same results if I connect directly to the modem's Instead.
Are there any other suggestions on settings or checks I can look at between phone and network that anyone can think of? This only seemed to happen within the last couple months, too. When the phone was brand new, everything seemed fine.
Edit: Workaround / half solution found, post #6.
Howdy. I just got the S20+ 5G from Verizon. I noticed my mobile data connection going in and out fairly often and texts getting stuck sending. I also noticed wifi calling draining the battery. I've disabled wifi calling for now. I'm a little peeved a $1200 phone has an issue like this.
I know it's been a bunch of months, but I just wanted to follow-up with this. I haven't found a solution but I've all but ruled out the phone as the culprit. As it turns out, all the other phones suffer from the same issues. I even bought a Verizon LTE Network Extender, which has at least solved my text issue - they work reliably now. But voice calling is still a one-way street. Calls can come in, I can hear the other person all day long but nothing can be said back. Since it happens the same way on all the phones, and since it happens even with the network extender, I can only assume the issue lies somewhere either in the modem settings somewhere that I haven't found, or in the ISP backbone itself. Sadly, they're pretty worthless when it comes to tech support (and I should know - I work for them...). I've tried most things I can think of in the modem/router itself, took out my Google OnHub altogether, and still nothing. I've heard ports opened up being a common issue but for some reason, the ports that most people suggest are already showing in use and unable to be set aside. I revisit the issue every few months, but if I ever do find a solution for my case, I'll post back then.

From what you've shared the connection issues would point to your ISP. If you haven't already done so request Verizon do a reset on the fiber connection or switch to DSL if they offer it. At times a COLO, the actual distribution point closest to your home isn't properly maintained or the equipment is in need of upgrades or repair. The only other consideration might be a firmware defect. If your S20 Ultra is operating on Unlocked FW you might want to flash Verizon's latest FW to your device. ATT/Verizon are notorious for compatibility issues with non-native FW.
I actually just came back to add more confusion to my post, but I'll answer above as best as I can:
I don't have Verizon for home service, but Verizon Wireless for my cell. My S20 Ultra was purchased directly through the store, with all Verizon updates installed and current. My home internet is new 50/50 Fiber internet, which was just deployed to the area about 8-9 months ago. I was the first person on the loop to be installed, and it runs fine. I could up the speed if I wanted, but have no need for more. It's new cable from the unit in the field, up to the road, and new drop to the house and new equipment. From that standpoint, everything has been rock solid and works fine. I certainly am not letting them off the hook (or, wasn't until five minutes ago) for what might be a setting somewhere between points.
However, during some more testing, someone mentioned they had an issue with WiFi calling not working. So I did more testing with my S20 Ultra. Turns out, WiFi calling isn't even working at all on my device. I can place it in airplane mode (so it doesn't see my Network Extender), enable wifi, and no matter what I try to do, it will not recognize WiFi for calling purposes. I can enable it fine, it shows enabled, I can restart and toggle all day long. But the moment I try to make a call that way, it tells me I must turn off Airplane mode to make a call. This is in spite of the phone having wifi calling enabled, with WiFi set as the preferred call type in it's settings. This is full wifi from within feet of the router. On a whim though, I took out my SIM card and put it back in my S10 5G sitting in it's box. Calling works perfectly, on both wifi calling, and the network extender. So all that did was confuse me more.
I have an S9+ that doesn't work. I have an iPhone 11 Max that doesn't work. I have an S20 Ultra that doesn't work. But an S10 5G that does. It's the only phone I've found in the house so far that I can make or receive calls from/to, and be heard on the other end. All the other phones, connected to the same wifi and the same network extender all suffer from the same thing. At this point, I've basically hit a wall and am ready to throw in the towel. I was ready to spend another evening messing with the modem until my S10 worked perfectly. It worked on the extender fine. I put it to Airplane mode, enabled wifi calling, and within twenty seconds it registered an outgoing call to my house as a wifi call, completed, and could hear fine. A bunch of coincidences all at once. My fiber internet came with a new modem, though the same model that my regular DSL used prior - when everything worked fine. This new one is configured exactly the same, I kept the wifi configuration exactly the same as before to eliminate having to set a dozen devices back up. So I thought that change still somehow did the phones in, as it was shortly after that I realized that they weren't working right. But then the S10 connected just fine, using the same new modem and everything.
Pretty sure I just live in the bermuda triangle of befuddlement here. I'm just going to abandon trying to figure it out, and go back to just calling back anyone that tries calling, from my home phone instead.
A workaround /semi-solution has presented itself:
The reason my S10 worked was because it was connecting to the 2.4GHz radio instead of the 5GHz one (my router is set up with both configured through what is called "Total Control Wireless" where it configures both under one umbrella with the same SSID, security and password and then lets the devices pull whichever it prefers). But my S10 still had my 2.4 guest wifi in it, and connected to that without me realizing it.
By switching my S20 to Airplane mode, and connecting to my 2.4GHz guest wifi, it works. It does NOT work though, if I don't enable airplane mode. I believe this is due in part to some others I've seen posted where the Samsung phones will automatically attempt to use cellular signal regardless of wifi calling enabled or set as preferred. Noting that the preferred call type is under 'roaming' and likely not subjected to just always using it. So it sees a signal at all, be it from the extender or from even a small signal seeping through the wall, and I guess it tries to use that instead of the wifi. Airplane mode on, 2.4Ghz radio, and I can make and receive calls all day, with no issues with voice.
I still have some more to play with, like disabling the 5GHz band altogether, and so on, but for now at least, I seem to have narrowed it down. Even though this router is set up exactly as before, my guess is something in there isn't liking it. I even set up the 5GHz guest radio, which did nothing either. But for now, I at least have a workaround, even if it means having to remember to disable airplane mode when I leave the house. I think there's rules I can make for that somewhere...
Last follow-up. I don't know if this is really a solution, but for future reference:
I disabled the 5GHz radio in my modem/router. For records, it's an Arris NVG448BQ. I'm not sure what would've changed from the old modem to the new, but I guess it's possible that I didn't have both bands enabled on that one.
However, changing to strictly a 2.4 GHz radio has eliminated the issues altogether with my S20. I will be able to test the other phones later but I suspect the same thing. I don't think it's so much the phones as much as it is something somewhere in the 5 GHz side of the router, despite being unable to find any difference in the way they were set up. I even left it enabled as a separate SSID, and still nothing.
I also was able to disconnect my Network Extender (glad I spent money on that...) and thus eliminate the need to toggle airplane mode on and off. I was worried that the phone would still see a trace amount of cellular signal and prevent things from working, but I made a 30 minute test call on wi-fi calling (which now shows enabled reliably and available, no funky restarting or toggling needed), and repeated testing with sending and receiving text and SMS messages are all working as they should once again.
As far as phone-related though, I'm calling this one solved finally. I do suspect that with a better router and advanced band filtering, I could make things work somehow, but I really don't have any need to do so at this time.
Case closed.
Confirm carrier setting. Or re install carrier setting.
Go to setting / general / about.
Network must be Verizon 4G LTE. Network is good all the time.
HD Voice is activated/
Charlz0_2000 gives 2.4 GHz setting is the best solution here available.
As a follow-up to my last follow-up, and I promise after this one, I'm done. The ultimate cause of all this, was a faulty modem - which I half-suspected at times anyway as there should be no reason an S20 shouldn't be able to use the 5GHz band for Wifi calling. My Modem started completely rebooting at random a week ago, and I finally was able to get a replacement today from my ISP. As soon as I had it installed and configured, I connected to the 5GHz band with my phone and was able to make and receive calls over WiFi with no issues at all. I will keep the bands separate as I do have some smart devices that have a hard time with the "smart" umbrella that the modem defaulted to.
But just for future trouble-shooting for others with WiFi calling issues, it's worth a shot to try one band or the other specifically as a work-around.
Cheers all.
