HTC one X unlocked international Version

Welcome aboard. Sorry to hear that - hopefully if there is a solution to fix this, I'm sure you'll find it here on Android Forums.

Best of luck.

 

cherine - you may be best heading to http://androidforums.com/htc-one-x/

Did you get the phone from your carrier or elsewhere?

 

from another forum, get another micro sim card from t-mobile...it needs to have the number 50.01 on it...the one they gave me when i had my unlocked phone was a 50.05. i went back and they told me they gave me the non-GBA card, but now looking it too was a 50.05

tomorrow i go back and call trying to find the right card with a hard identifying marker of the 50.01 on it...the number on the card (next to the pink 'T' on the card)...on another forum a poster verified this worked for him.

good luck...i'll verify this...this whole episode has been very frustrating
