Non-ATT Pixel 4a suddenly unstable network connection (voice and data) following June 2022 pixel update

I have a Pixel 4a bought from Amazon (unlocked) which has worked flawlessly on ATT's network since I bought it 13 months ago (1 month past warranty). Following a trip abroad where I used a foreign SIM for 3 weeks and during which time the June 2022 Pixel update was installed, when I reinstalled my ATT SIM the network reliability has been horribly shaky - wildly fluctuating connectivity to ATT network. Data speeds have been very inconsistent (ranging from fine/normal to almost unusably slow), but just as frustrating, in certain areas of town (I live in metro Atlanta), people cannot hear my audio (or it's so choppy they can't understand me) on phone calls, while I can hear them perfectly. It's not the mic hardware, because when connected to wifi and using Skype or FB Messenger, people hear me perfectly. I can always hear the other end of the phone, but they usually cannot hear me unless I"m in a magic area where the reception is perfect (even if it shows 4 full bars of ATT service.)

Here's what I've done to troubleshoot thus far:

  1. performed network reset
  2. installed new SIM card from ATT store
  3. performed factory reset (via Google tech's suggestion)
  4. cleaned microphone at local UBreakIFix store
  5. manually created 2 new nxtgenphone APN entries and let them populate for over 48 hours each
  6. Restarted via countless 'processes' that ATT tech support has pushed to my phone during 7-8 phone support sessions
  7. Ensured I have the most recent Android 12 update

ATT claims they've done all they can and that everything is fine on their end. Google says the phone hardware looks good. It's almost definitely a network-related issue, almost like the radio is having issues sending an outgoing signal (data or voice), but incoming is largely fine. And it only happens in certain pockets (most of Atlanta, as it turns out).

I've heard that since ATT has been decommissioning their 3G towers, non-ATT devices have sometimes struggled with network issues. This seems to be something like that, but no one seems to be able to identify a fix. Any suggestions welcome, as this is approaching the point where my 1-year old phone is becoming an unusable relic. Thanks.

I should add that the issue persists as described above even when connected to other devices (car, Google Buds), on speaker, and using just the headset.

Hello @vanuva, we understand the importance of staying connected. 

 

We have shut down our 3G network to bring you faster speeds and new features. It’s important to check the device model numbers to make sure it’s still supported since the 3G network shutdown. This includes iPads, tablets, and wearables. Check out our list of unlocked devices that have been tested and approved to use on our Network. 

  • Keep in mind: Models listed here are not guaranteed to work on the AT&T network. AT&T cannot guarantee the capabilities or performance of any individual device that was not purchased directly from AT&T or an authorized retailer of AT&T.

Talk and data services will only work for AT&T Wireless phones and devices that support at least 4G LTE and HD Voice.Your phone will work if the HD Voice feature is turned on. If you can’t make or receive calls, or you’re having trouble accessing data, check the VoLTE or LTE status of your phone. Here’s how:

  • Go to Settings and then Connection. Choose Mobile networks and then Enhanced LTE services and select On.

Since we shut down the 3G network, there won't be data or voice service for devices that don’t have at least have 4G capabilities. This means that while some device features might still work, you won’t be able to access our network unless you upgrade to a newer device. We're here if you have any questions. Thank you for contacting AT&T Community Forums.

@ATTHelp, thanks for the reply. Do you have an updated list of devices that should work after the 3G shutdown? This list was dated in 2020, but my phone (and many other modern phones) are not listed because they didn't exist at the time. I have a Google Pixel 4a, and it should definitely still work.

Another update: I took the device to the Google Authorized repair shop (UBreakIFix), who performed 4 hours of diagnostic tests and declared the device working properly. So there's definitely some type of network connection issue with my phone that is not hardware-related, but again, only in one direction (I hear people fine, they can't hear me when I'm in an area with unstable connection.) Any other ideas?

Thank you for reaching back out @vanuva.

 

We recommend using Wi-Fi Calling that lets you talk and text over an active Wi-Fi connection. You can turn Wi-Fi Calling on or off in your phone’s settings. Wi-Fi Calling is used when a cellular signal is weak or unavailable or when you have an unstable connection. 

 

To view the locations AT&T voice and data service can be used, see the AT&T Network coverage map.

 

Sometimes, your wireless device or its settings can cause connectivity issues. Make sure you have your device handy and try this:

  1. Go to our troubleshooting tool.
  2. Select your phone brand and model.
  3. Choose the option in Connections that's giving you trouble (for example: Internet or Phone calls).
  4. Follow the prompts to fix your issue.

Let us know if you have any questions. Thank you for utilizing the AT&T Community Forums.

Yes, I've been using wifi calling when connected to wifi at home, but obviously I need the phone to connect to the network when not connected to wifi as well. I've chatted with several phone reps, the latest of which discovered that my phone was only connecting to some towers in our area that are apparently undergoing repairs, and when he tried to manually move my phone to some other good towers (which the other ATT phones on my account in my house are already connected to), the phone wouldn't connect. He didn't know why that was happening, but said he would call me back in 24-48 hours (48 hours will be tonight) in the hopes that the towers would be fixed. Not optimistic, and it still remains that my phone will not connect to the right connections automatically following my return home (and following the installation of a brand new ATT sim card.) Thoughts?

Hello, @vanuva! We want to help with getting your device connected to the network!

 

Let's meet in a Direct Message to further discuss how to get the device connected to the AT&T network. Please check your Direct Message Inbox (it's the chat icon next to the bell icon in the upper right corner of the Forums). 

 

In the meantime, make sure the make and model is on the list of supported devices on the AT&T network.

 

Look forward to chatting with you soon.

 

Thank you for reaching out to AT&T Community Forums!

It's been 3 days since the last of several 'escalations', and still the issue is as bad as ever. I've been with ATT for nearly 20 years, but this is forcing me to consider switching our whole family to another carrier. Either fix the issue with my barely 1-year old supported Pixel 4a phone, or get me a new phone that works. What is going on???

Were you able to get your issue resolved? Unfortunately I just bought a pixel 4a that has not yet arrived. Concerned it may not work.

No, it has almost no cell (phone) connectivity.  ATT gave up and said it's not their problem (awesome) and Google said since it's a couple months past warranty they won't do anything to help. It worked great for a year though, so hopefully you'll get lucky.
