Hello there Katheylee31. Sorry about that. Sometimes that may happened, specially with iPhone devices. Please do the following: Make sure that you have at least two or three bars. If you have an Android please turn off your WiFi and Mobile Data on.
On you dial pad, enter ##72786#. When prompt say Yes or OK to all you see there. If you have an iPhone: 1. On your dial pad enter ##873283# and press call. 2. When Service Update appears, say OK to start the programming. 3.When Service Update Complete, again agree and press OK. Please let me know if that worked out.
