I have bought R-SIM 9 pro cards from ****** and all of them have the same issue iphone activates shows carrier but i can't make calls. I have tested on 4 different devices from different countries: iphone 5 uk and ireland iphone 4 france and uk. So my question is it possible downgrade or upgrade R-SIM 9 pro inner software?

p.s. i have checked cards serial number and it is genuine

I've got the same problem, iphone 4s runninng on iOS 7.1.1. Sim activation was fine, but I cannot make any calls.

I checked on internet that I cannot downgrade iOS from 7.1.1 to 7.0.6.

How can you upgrade R-SIM 9 pro (by) software? I'm much interested.

If your iOS is too new R-SIM 9 Pro won't work anymore.

And no, it's not possible to update the software of that card. Updates are possible with e.g. MINI2, though.
