I have an HTC One S that I am trying to use Straight Talk on. It's a t-mobile branded phone so the Straight Talk sim is their t-mobile one. The problem is the apn settings are locked to T-Mobile. I can set an apn for Straight Talk and then choose the button for that apn. But as soon as I leave the settings screen, the apn reverts back to the T-Mobile setting which has a padlock by it. The phone is unlocked but that doesn't solve the problem. I have talked to Straight Talk, HTC, and T-Mobile and they all tell me that the other company needs to fix it. Finally a tech at T-Mobile said I need a puc code or sim subsidy code but I would have to get it from Straight Talk. ST says they don't have the code.
Can anyone help?
