Lumia 521

What’s today? Today is the 20th of May, which means if you’re rocking a Nokia Lumia 521 on T-Mobile you should be getting a killer update. A killer update that adds Wi-Fi calling. Users on Reddit are seeing the update now. Ready to update? Details below.

About a week and a half ago we learned that the Lumia 521 would be supporting Wi-Fi calling on T-Mobile with a future update. Today is the day that the update will begin rolling out to users. If you’re impatient and want to try and manually check for the update just:

  • Go to settings
  • Scroll down to phone update
  • Click on check for updates

If your phone finds the update on the servers it will begin updating. But a word of caution about this particular update to version 1020.6409.1316.0016. It’s going to require a master reset to complete. That means your progress in any games will be lost and you’ll want to make sure you backup everything else.

Update: Reader of the site JKjeeper posts below on how to get this Wi-Fi calling to work:

"You should contact Tmobile and have your Sim Card provisioned for WiFi calling (you might need a new Sim Card) after this just connect to WiFi and open the WiFi calling tile and your will have 3 options "WiFI Preferred, Cellular Preferred and WiFi only" also when you are connected to WiFi calling MMS wil not work"
