My sister was messing around with my phone and now it wont let me do anything without a PUK code and I called the support line and they said that my phone does not have a sim card but I double and triple checked and there IS a sim card under the battery CLEARLY labeled SIM.
Later I found out that if i turn off the phone and put the sim card in backwards then it will work fine, just no calling or texting and no internet without wifi. If someone knows how I can find the PUK code please tell me.
I have a HTC EVO design 4G running android 2.3.4.
It may be that a setting was changed in your Roaming settings. Check by going to Home - Menu - Settings - Wireless and Networks - Mobile Networks - Roaming - Preferred Network. If it's anything other than CDMA only, change it back to this setting. Otherwise you can contact our world wide care department.
The "PUK" code is for a SIM card for international service. Please call the Sprint World Wide Care group.
