I'm sorry it has taken so long to get back with everyone, my daughter came into town from out of state unexpectedly and we had a family get together, not to mention having 6 children here at ome keeps me pretty busy. Also, trying to do some canning from the garden along with the normal household chores, blah,blah,blah....
Phone does not have a keyboard, it's touch screen. Meaning when you start a text a touch screen keyboard comes up. It has a pull out antenna, and a great camera! I had a red verison of this phone and I LOVED IT!!! I wish I had the extra 48 credits to big on it. Its a very good phone, I'm not the seller, and do not know the seller, but I'm letting you guys know, this is a great phone! It's worth the credits I promise!
I really don't know, I think that you can use any AT&T phone if you own it and get a plan or use a prepaid plan, you could call their customer service and find out.
