wifi calling

T-Mobile has begun informing affected customers that on May 31st devices using WiFi Calling version 1.0 will no longer be allowed to make WiFi calls.

The news comes via a post on Reddit where a user received a text containing a link to this page on the T-Mobile website. It states that a select number of older devices will no longer be able to make WiFi calls after May 31st.

The affected devices are as follows:

  • Alcatel One Touch Pop Astro
  • Alcatel Fierce 2
  • LG Optimus L70
  • LG Optimus L90
  • Microsoft Lumia 640
  • Google Nexus 6
  • Samsung Galaxy Note 4
  • Samsung Galaxy S5
  • Samsung Galaxy S4
  • Samsung Galaxy S III LTE
  • Samsung Galaxy Exhibit
  • Samsung Galaxy Avant
  • ZTE Obsidian

Customers using these devices will still be able to make calls over the T-Mobile cellular network as well as use data over WiFi. The change affects customers on T-Mobile, T-Mobile Prepaid, and Metro by T-Mobile accounts.

T-Mobile says the changes are due to ongoing technological improvements in WiFi Calling. Version 1.0 is being “decommissioned” due to it now being obsolete.

Affected customers can either opt to upgrade their device or accept the change. Calls made after May 31st will default to on-network calling rather than via WiFi.
