My IPhone 3GS won't send or receive calls or text messages. Why?

[Designsbybeth87]

My phone won't send or receive calls or text messages, but it will let me get online and check my email and even play games. My mom and I have a plan together and live in the same house. Her phone is doing the same thing, but she doesn't have an IPhone. She has an lg slider. What is going on with our service?!

If both phones are experiencing service related issues, there could very well be a service outage in your area. I would consider calling customer service and inquiring if they know anything about an outage in your area. If not, you can then report it.
