Ace 2 is unable to send msgs

Posted by hxsa
Got my first Samsung Ace 2 this October but kept freezing and draining battery horrible. Soon Had the store sent me a replacement, brand new. Battery life problem fixed as I pop in an 5000mah battery out of mpj, but lost all apps I installed, and what's worse is text messages. All it says are"failed"!! Any one tell what causing msg failures and how to fix it please?
Thanks!
