My husband's phone won't even get any service. He's not very happy he spent $50 and he can't even make a call.

Welcome to Android Central. I can give you 2 options. 1) Take the phone to your carrier and have them make sure it is provisioned correctly, and, if necessary, provide a new SIM card. 2) Reach out to your carrier's tech support using a different phone and let them troubleshoot the device.

The carrier may need to help with that. Has another SIM card been tried? If it has and it worked, then the carrier needs to be involved.

Hello, this problem causes when sim card slot doesn't registered in Network, my advice is call your network administration for sim card registration.
You should register sim slot by that IMEI code in your network operator.
