Have a Pixel 7 with Stock ROM. I have massive connection problems. There is a Telekom SIM inside and an O2 E-SIM, it constantly happens that my phone has no network connection, no matter what network, that the Internet offline, etc.
Especially when switching WLAN to the 5G network.
Does anyone know these problems and have maybe a solution?

There seems to be an ongoing problem with T-mobile and MVNOs. I don't know much about it except that 5G and Pixels are involved. Until the problem gets sorted out a temporary fix may be to set 'Preferred network type' to LTE/4G for one or both SIMs. Also try disabling 'Mobile data always active' in Developer options.

I'm not rooted, and have stock ROM. It's a SIM-Free HTC One. Connected to EE network in UK.
I've got a fairly new issue that I just noticed in the last week. My HTC One is my second phone so I don't use it as much, but I'm at a point where I want to get rid of it due to the following issues:
I can't make calls, it would sometimes connect but i can't hear anything. This doesn't seem to be a network issue as a user with an iPhone5 seems unaffected.
I can connect to my 5Ghz WiFi network, but not the 2.4Ghz one, it just saves the password but won't connect. I've also noticed if i disconnect from the 5Ghz network, restart phone, i can make calls and hear the other side.
Using Data network, it doesn't seem to want to load anything, it shows 5 bars HSDPA and either goes incredibly slowly or just doesn't load at all.
General performance issues, everything would become incredibly slow, stuttery and incredibly annoying to use. yesterday the device crashed and restarted.
Any ideas what I should do? Try a full reset (ugh...) or is the device faulty in some way and I should contact HTC Support?
go to the dialer and type
*#*#4636#*#*
choose phone info, scroll down to the only dropdown box and select the correct setting for your provider ( wcdma preferred if you don't have a 4G contract)
and then back button about 4 times and try it again
It seems to be the way it should be: GSM/WCDMA/LTE Auto. I was in France a week ago and it had serious issues roaming and data roaming, i had to change it to GSM/WCDMA auto or WCDMA only to make it work. and now back in UK, i set it to the same setting it used to be before I left.
On a side note, I have realised that EE is having data network issues in my area. I tried the SIM in another Galaxy S3 and it had difficulties loading websites, but, it COULD make calls without problems.
Also, no crashes as of today on the One, I still can't connect to my 2.4Ghz wifi router. Could the fact that I was using 5Ghz somehow messed something up inside the One?
Hello,
My I9000 has a peculiar problem: While both mobile internet and Wi-Fi work fine, switching to 2G when 3G/UMTS/HSDPA coverage is bad does not. It ends up losing network connectivity completely in areas where other phones have no problem staying connected by switching to GPRS/EDGE. (3G coverage is spotty here at times, so this matters quite a lot.)
This problem has first appeared rather spontaneously when it was running its stock 2.1 firmware and has persisted through upgrades to stock 2.3 and CyanogenMod 10 through 11. I've attempted to switch modem firmware to mitigate it to no avail. (Modems XXJVT and ZFJPG/BVJJPG were tried, no difference was noticed - I am rather wary of messing with modems further, as this is my only phone and I'd rather it still could call at the end of the day.)
Moreover, if network mode is switched to GPRS/EDGE manually, it can't be switched back to 3G (either manually or automatically) without a reboot. (The 'set preferred network type' field in *#*#4636#*#* starts resetting itself to 'Unknown' spontaneously at this point.)
Unfortunately, I don't know many details of the incident that caused the appearance of the problem, as I was not the owner of the phone at the time - I only know that it was roaming nationally (within the same country) at the time. (The network type should have been the same, and it's not like it's stuck in roaming in any way.)
Has anybody encountered such a problem before? Is this likely to be a hardware problem, or could there be a software fix?
Thank you in advance for your thoughts.

you need to try fiddling with its network settings (read this for info only) you can use service codes on i9000 to set your network settings . Sometimes it may be due to network settings not set to Auto and set to preferred and at other times it could be antenna connection inside the phone having poor contacts.

Thank you for the hint. I have tried setting the "Select radio band" setting in *#*#4636#*#* > Phone information to European bands manually, and this appears to have mitigated the problem at least partly (phone has switched to 2G and back a few times during the day). I've noticed that it would sometimes just turn mobile data off despite having a good signal, not sure if this is related. It also sometimes seems to prefer another operator's 3G network to its own 2G ("emergency calls only", network mode is UMTS/HSDPA), but this is only guesswork since I have no way to actually confirm that the areas where this occurs have 2G coverage (it just seems really unlikely that they wouldn't). Maybe the fact preferred network type is "WCDMA preferred" factors into this.
TL;DR: Forcing radio bands seems to have helped, other radio weirdnesses remain but aren't nearly as bad.
Hi
I am in Kolkata India and recently switched from a 2G to a 3G plan with Vodafone Kolkata. Ever since then, my problem is that I am unable to connect to 3G using WCDMA. Neither voice nor data works. If I revert to GSM only, then voice and 2G works fine. Wifi has been fine and my saviour at home.
Phone details: Sony Xperia SP C5302 running Android 4.3 build 12.1.A.1.205.
I have confirmed with network service that it is not a SIM card issue, by carrying out the foll. tests already
1- Signal strength in the area of use : At the time when I am unable to connect to 3G, my colleague sitting in the next desk and using a Motorola phone is consistently able to connect to the same 3G network from his phone. So the network strength must be fine.
2- SIM damaged or dirty - I have obtained a new SIM card as replacement, after this problem started, from my service provider yesterday. But the problem is not resolved.
3- Manual network search and connection - I have tried this many times, using WCDMA only or WCDMA(Preferred) options. In either case, only on rare occasions, the phone was able to connect to a network. However, 3G data connection (H+ icon) did not show and then the phone disconnects from network. On most occasions, when I manually attempt to connect to the 3G network, I get the message "Could not register to the selected network. Make sure SIM is inserted."
3- Trying different SIM/Handset - I have tried out both options of switching SIM and handset.
- My SIM on Motorola handset - connects to H+
- Another SIM on my Sony - momentarily connects, then disconnects and then does not connect to network.
Please let me know if anyone has faced similar issues and found any resolution. Thank you in advance.

I think that there's an option to use 2G instead of 3G in the settings menu, have you checked to see if that is enabled?

That is the WCDMA option I've mentioned about, there was no other setting for this.
Anyways, it turned out to be a hardware problem. Got the "mother-board" replaced for free as it was under warranty & now working fine!

Good to see that you've sorted out the problem!
Hi guys!
Around 2 months ago I started having some issues when connected to the 3G network. Most of the times, it didn't transfer at all and my network icon was with the "!" sign.. I was on PAC LP and I blamed it (or some software-related cause). However, if I marked "Use only 2G networks", it did work...
I flashed the phone yesterday. A clean, fresh and quite deep install (wipes, .228 FTF, new kernel, new ROM -eXistenZ-, etc etc). The surprise was that I still have it... If I try to connect to 3G networks I might get a couple of seconds of connection, but then it just disconnects and stays like that until I change back to 2G networks... Just in case I reflashed again, same procedure, and it's still there, even on stock .228...
I bought the phone 2 years ago (in Europe, that's why I can't use LTE here), and never had a problem like this. Of course, I'm at the same place with 3G coverage (other phones do work), I've already tried different APNs, providers, etc, so I hope not, but I'm starting to think this could be related to a hardware issue...
Does anyone have an idea? Is there any software part that is not changed during a flash and could be responsible? Or maybe how to rule out hardware or software issues? This happened while I was on PAC LP, stock .228 and eXistenZ...
Thanks in advance!
It could be many factors involved - one of them could be that the operator you are currently connected (ex. Vodafone, At&t) maybe changed all their antennas in your area from 3g to 4g, and that would result in your lack of connecting to 3g.
I once changed my operator because it had better offer and then I regretted it since the connectivity was worse with the second operator and would constantly switch from 2g to 3g to 4g, all this with a major impact on battery life.
It could be also hardware related, but I wouldn't bet on it. Try checking with another phone with the same sim in the same areas to get an idea what it might be.

Hi aaronkatrini.
Thanks for your answer! However, it's not my operator's fault:
- All other phones in the same area do work.
- Other operators (other SIM cards) in my phone have the same issue, so I guess it's related to my phone, software or hardware...
I haven't checked yet another phone with my SIM card, I could try that to rule completely out the SIM card/operator's fault.
Thanks again!
Long story short: My P5 is stuck in CDMA mode for mobile voice network and will not go into 5G mode. My wife's P5, is fine. I have been getting dropped calls like crazy, in areas where reception is usually fine. So I am trying to figure out what's wrong with my phone.
I tried swapping sim cards between the two and that's when it got strange... My sim card in her phone worked fine and immediately got on 5G and LTE for voice network, and her sim card in my phone did just the same. When I swapped them back, then my phone went back to no 5G and CDMA voice network and her phone was just fine again.
So, why does my phone not like my sim card? What could I check on my phone settings that may produce this behaviour? Obviously it's not a hardware thing or my phone would have done the same thing with my wifes sim in it, so I am baffled.
Any ideas would be helpful. I would love to avoid a full wipe...
Thanks
Do you have Adaptive connectivity enabled? Maybe try disabling it? Settings -> Network & Internet -> Adaptive connectivity.

Thanks for this. I believe I had already done this. But following up in general, I did a reset of mobile, wifi, bluetooth, and my connectivity to 5G returned and my mobile voice network began acting normally again. I need to see how my call quality is this afternoon when I can test it out.
