Hi folks,

About a week ago my LTE data stopped working on my iPhone X. It is an unlocked GSM phone. Voice, text and Wi-Fi work fine. I have had the phone for about 3 years and have been with Straight Talk that whole time. I am in the US.

I spent about 4 hours total with ST tech support with nothing getting resolved. I took the phone to the Apple store and all hardware tests passed. The Apple tech tested my SIM card in another phone and the LTE didn't work there. She then put her personal sim in my phone and LTE worked. So I am pretty sure it is not the phone.

I even ordered another SIM card from ST and still the problem persists.

I would really appreciate and help or pointers. Thanks in advance.
