I currently have an iPhone 3G, unlocked, and my phone can find service. It says T-Mobile on the top left corner. But, why can't my iPhone make or receive calls? I can only make and receive calls if I reset the iPhone network settings, or when I reinsert the SIM card, which is very annoying and inconvenient.
Any suggestions?
(By the way, sometimes, my iPhone can't find service at all out of nowhere, like in a park or movie theater. Is it because of my SIM card, iPhone, or the place?)
