I had rogers and used to receive all txt etc and even voicemail icon showed up on iphone.(unlocked)1.1.1
however, with the fido sim card,i decided to switch to fido,I can check the voicemail since fido gave me the number to program for voicemail

but i cant get sms text to be sent or to be received.

fido gave me a number 15149931123 but im not sure where to enter it for sms in the iphone.
any advice
