It is a restriction on making international texts. It drives me crazy, because I can't initiate a call with my mother-in-law in England. But if texts me, it will let me respond. I've gotten around this problem by just keeping one of her text in my phone. Then I just use it to "respond" with my new text.
On Tracfone.com they give you a special 1800 number just for international calls and when you call it it will give you instructions to call wherever
How could I eliminate restriction 45 to my tracfone ell phone
