Our phones are NOT "hacked", jailbroken, or unlocked. We just have turbosim hardware unlock. As I said, we can make calls and send outgoing text messages, but the phones never ring or indicate anything about incoming calls. Text messages arrive in a flood when we make an outgoing call. 3G was working fine until a few days ago, when it abruptly stopped. We have open-plan accounts, not prepay. We have OS 2.2.1 modem firmware 02.30.03. Any help would be appreciated! Thank you!
