I purchased & R-SIM, so I could use my iPhone 4S on the T-Mobile Network. I have iOS 5.1 & everything worked fine. I rebooting my iPhone & now the R-SIM is not working. Has anyone else had this problem? I'm without a phone now & I need to find out how I can get my iPhone up & running again. Thanks.
Hey not to steal your thread, but have you gotten imessage to work with your sim card? I can only get my email address to show up and not my phone number.
Al it's saying is either Invalid SIM or No SIM Installed. My phone number isn't showing up, but I am able to get email via Wifi.
is the phone AT&T? and which r-sim do you have?
Its the AT&T iPhone. Its the 5.1 GPP Turbo iPhone 4S 4GS Unlock Ultra Card SIM Rebel.
