If you have a text plan that is $10 or more, they are mobile to mobile messages (read free), the $5 text will deduct from your 250 allotted messages. If you already have Unlimited text, then this was a pointless post.... Text away!!!
Alltel customers will only fit into the mobile-to-mobile criteria if they're NOT in a divested area. When in doubt, go to http://www.verizonwireless.com/ and click on Mobile To Mobile on the main page. You'll be able to input your friends' numbers to see if they're mobile-to-mobile. Not all Alltel customers are making the transition, so it's very important to check.
I did what you said to do about typing in the number since its alltel and it says its the mobile to mobile thing. But when i text the alltel number it counts in my 500 non verizon texts. Whats up with this?
