How to update an unlocked samsung to be compatible with wifi calling?

I have a model an unlocked Galaxy S20+ 5G (G986U1), which according to this(https://www.att.com/idpassets/images/support/wireless/Service-Capabilities-Unlocked-Devices-ATT-Network.pdf), is capable of using wifi calling when unlocked if it has a software update. The wifi calling option is simply not available. It's not not working--it's not there. It's not in the connections section nor is it in call settings.My software is update to date as it'll let me on the software update section of my phone. It's G986U1ES3GWA1. If not via the software update section, how would I update my phone to have wifi calling?

Hello mangogodatabey, we're here to help you get the update to use your device.


If your device is compatible but is not connecting, the following may resolve the issues:

  • Program the data settings for your non-AT&T device
  • Get a 4G SIM for your 4G device or a 5G SIM for your 5G device
  • Download the latest software – If you are an AT&T Customer, software downloads are automatic. If you have a non-branded device, you will need to go directly to the manufacturer.
  • Make sure 4G is enabled on your device. Some customers disable 4G.

Samsung devices will have an update available via Samsung as late as June 2022. So if you brought your own device, please visit Samsung Support for update information


Feel free to reach back out if you have any other questions or concerns.
