can you put a pay as you go sim in a bill pay phone?

I bought my brothers iphone and while he was a bill pay customer iam a pay as you go customer with the same carrier. so i thought i could just but my sim in his phone and use it. Im now having trouble sending and recieving calls. I can sometimes make a call but nobody can call me. I can send and recieve text messages fine. I have a good signal and the phone says its connected to the carrier. Can any one tell me if the problem im having is because the phone was a bill pay phone or is it that the phone is just broke. Also i would just like to include that the phone seemed fine for the first few days i only started having this problem when the battery went completly dead during the night and turned off and when i charged it back up i started having problems. Ive tried reseting the phone setting it back up as new phone but still i have this problem. Any help on this would be greatly appreciated. see below for the error i get when i make a phone call. Means nothing to me but maybe someone on here will understand it
