    Default cae82650

    I have a Samsung Galaxy S3 phone that I switched from T-Mobile to Straight Talk. I can't get connected to Wi-Fi. It says invalid sim. Sim card needs to be updated for Wi-Fi calling.

    I am not sure myself, but I can bring on someone who has more experience with this.

    My understanding is that wifi calling is not available for Tmobile's mvno's. You have to use t-mobile directly, either postpaid or prepaid.

    Dpham is correct. You're on a MVNO since you're on Straight Talk. This means you're using T-Mobile's network but from a 3rd party instead of directly from them. The wifi calling feature only works for people who setup their accounts directly with T-Mobile.

    Doesn't matter what settings you use, T-Mobile knows that you are on a mvno, and disallows wifi calling.

    My friend is on family mobile (also tmobile mvno) with a Tmobile Note 3 and cannot get 4glte, regardless of setting.

    Certain features are reserved for tmobile only, and features can vary depending on the mvno agreement with tmobile. But Afaik, no tmobile mvno has wifi calling.

    Does it say 4g or 4GLTE in the notification bar? On family mobile, it only supports 4g (hspa+), not 4glte.
