Last night I was texting my BFF in Oregon, light came on said needed to charge battery. I plugged in the charger and immediately got message that said only could make emergency calls and data card was invalid. Let it stay on charger over night. Phone had full charge but still had the same message. Being it was Christmas Day and Sunday, no way to contact ATT Repair. I finally decided to remove battery and simm card and put them back in. This worked and phone has been fine all day. My question is do I need to turn phone off before plugging it in to charge battery. I tried to find answer in manual but it didn't say anything about that. DH thinks that because I didn't turn it off that may have confused it.
Its still under warranty its an Impulse 4G Smart Phone.
