Thanks behold_this
The Behold II 1.5 t-mobile is unlocked from t-mobile.
The phone is used from my daughter in Germany with a pre-paid card from e-plus everything works fine except she is receiving about 10 to 20 text (SMS) per day (no cost) from
“+491770702810 Die SMS konnte nicht zugestellt warden, da entweder die eingebene Nummer nicht gueltig ist oder das Guthaben der Karte nicht ausreichend ist”
I get the following answer, this is because the phone is branded to t-mobile and the phone tries to get updated from a t-mobile server.
Is there a ROM to solve this problem??? (fib need to work)
