Samsung Galaxy s22 ultra not connecting to network?

It's not really enough information. Did you purchase this phone from AT&T or directly from Samsung as an unlocked device? Or elsewhere?

Hello, @Jmiceli63. Thanks for reaching out to us about your connection to the network. We know it can be frustrating when your device won't connect. We can help!

Thank you @formerlyknownas for always responding with helpful insight and questions! We appreciate you!

Let's try these troubleshooting steps:

• First let's reset your network settings. To do this, go to Settings > General management > Reset > Reset network settings.
• Make sure your software’s up to date: Go to att.com/softwareupdates.
• Confirm you have wireless service. Make sure you have a signal. Check our network coverage map.
• Check your SIM card. You may have to take it out and put it back in if your phone displays Insert SIM or Emergency Call Only.
• Get device support.

Let us know if this helps!

I started having the same issue. ATT had me replace the sim card and it seemed to work briefly, he said it could take up to 24 hours. Now I am not even getting calls when connected to wifi. So the issue seems worse. I got my phone in February, preordered it through ATT when the phone first came out. I have to be connected to wifi calling in order to use any features.

Hello, @afrancois1! We understand how frustrating it can be for your device to only have service when connected to Wi-Fi!

Based on the information you have provided, let's meet in a Direct Message to further investigate the device not having service. 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, check to ensure your device has the latest software update.

We look forward to chatting with you soon!

I have been having the same connection issues for over 2 months now with my S22 Ultra and absolutely no one has been able to help me with my issue. I have reset my network connections multiple times & installed a new SIM card with absolutely no change in service connection outside of Wi-Fi.

I am beyond frustrated & have been looking into other options for mobile service in my area.

Hi @HWatson, we know how inconvenient it is when you can only call when connected to Wi-Fi.

We're here to help you get connected again. Have you already tried the all the troubleshooting steps in this thread? If not, then let's start with:

• Troubleshooting your calls by double checking if your phone is on airplane mode, along with power cycling your device by turning it off and back on.
• Make sure there's wireless service in your area, as coverage is subject to change without notice.
• Use our device support page to see detailed troubleshooting steps in the Calling & contacts, Connectivity, and System topics for getting your phone connected again.
• See if your phone needs a software update.

Also, since you bought a new SIM card, please make sure it's been activated as well. If it isn't, you'll be able to use that page to activate it yourself.

Please share the results with us here.

Dylan, AT&T Community Specialist

I have completed the troubleshooting multiple times prior to and after receiving the new SIM card. Spoke with a representative after receiving the new SIM to ensure that it was activated properly.

I have powered up my S20 Ultra and will be putting my SIM card in it to see if the poor connection is device related.

Thank you for keeping us updated, @HWatson.

In addition to swapping the SIM card out, please let us know what happens specifically when you make a call. Are you getting an error message, or is the call just dropped? This will help us narrow down what's going on.

Please let us know how that goes.

Dylan, AT&T Community Specialist

The call does not go through, or when it does, it drops. I am also unable to send texts or use mobile data the majority of time that I am off of WI-FI.

I have used less than 2G of mobile data this month (far below my past monthly average)

We appreciate this information, @HWatson.

Please share what happened when you swapped the SIM card in your S20 Ultra, this way we can continue looking into our options for getting you connected outside of Wi-Fi again. Also, let us know if the S22 works using the old SIM card from the other device as well. That'll help us narrow this down too.

Please let us know if it helps.
