FAQs

Why am I losing this call functionality?

There have been updates to the technology used to make voice calls over Wi-Fi that have made the original 1.0 version obsolete. To continue to improve the network experience for customers and stay on the cutting edge of voice technology we need to decommission the 1.0 technology.

Can I get it back somehow?

No, but you are able to upgrade to a new device that includes the newer technologies needed to make calls over Wi-Fi.

Will I still be able to make calls?

Yes, however it will default to the T-Mobile Network instead of over Wi-Fi.

Does this mean my phone doesn’t have Wi-Fi at all?
