Select T-Mobile customers in Orlando and Tampa have been getting text messages from T-Mobile over the past several days, inviting them to T-Mobile’s new “Preferred Wi-Fi Network Trial.” The purpose of the trial is to experiment with partnering with WiFi providers in these areas to offload some of T-Mobile’s network traffic onto WiFi networks, thus easing congestion for other customers, while providing a seamless experience for those customers who are on the WiFi networks.

For now, customers in the trial have to have a Passpoint enabled device, which includes:

  • Apple iPhone 5
  • Apple iPhone 5S
  • Apple iPhone 6
  • Apple iPhone 6 Plus
  • HTC Desire
  • HTC One M8
  • HTC One M9
  • LG G3
  • LG Leon LTE
  • LG G Stylo
  • LG G4
  • Samsung Galaxy S 5
  • Samsung Galaxy S 6
  • Samsung Galaxy S 6 Edge
  • Samsung Galaxy Note 4
  • Samsung Galaxy Note 4 Edge
  • Sony Xperia Z3
  • Sony Xperia Z1s

Passpoint is a feature on these devices that allows these customers to seamlessly connect calls, messages, and data through T-Mobile’s “Preferred Wi-Fi” access points, without having to manually connect to these WiFi networks. For now, this includes Bright House Networks WiFi hotspots.

T-Mobile warns that customers should have VoLTE enabled to receive the best experience – otherwise, calls will not transition seamlessly from WiFi to mobile, and could drop.
