anyone else having this problem? i have a razr.. and ehm where i live sprint doesn't work very well so our phones are always on roaming.. and it use to always work.. but now that i try to send texts it gives me that error code.. but if i get somewhere that i actually have sprint service... it sends it.. but this is a problem cuz thats rarely anywhere.. i just was wondering if anyone else has heard of this problem or is having this problem. thank you.
