Hi, I am new to the forum, so please bare with me.....I bought a brand new unlocked Blackberry Curve 8310 on eBay (to work with AT&T prepaid). I inserted my sim card and I can make calls and receive text but I cannot send a sms.

I called AT&T and they tried adding a Service Center Number and the Network to Send over to CS but it will not let me save the changes.

Any help would be greatly appreciated, I really love my new phone. Also I do not use the internet, just text and call, not sure if that matters.
