I followed the instructions by Sassha and finally got it working. All worked: call in/out and sms in/out. but after a while I got "No Service". I tried to restore and update and then reactivate. no help. My supersim works in my old phone perfectly but in iphone I get "No Service."

Anyone had the same problem?
Any Suggestion?

Thanks,
Hamed

...maybe it's the loose connection of the sim to the phone, silver sim when punched out from the card sometimes has rough edges on the sides, i got no service 3-4 times today, removed the sim, put it back and restart the iphone...
...i did file the rough edges with the nail file, don't file too much that it will make it very loose....
....i'll try to post again if it still happens...

I noticed that my phone only see one tower, the one that I first registered iphone with it. Anywhere else I get "No Service". I have heard that in Iran people should send their IMEI to the provider to register the phone in the network. I did so and waiting for the result.

But it is strange that my iphone works without any problem in my office and does not see my network any other place.

Hypersim, Turbosim and supersim? What are these and what is the difference between them?

"1.1.2 has been changed to recheck the SIM every time you switch towers so it doesn't work very well if you're moving ".

just replace the lockdownd file.

Replace the lockdownd file with what? And where can I get this lockdownd file? Also what does the lockdownd file exactly do? Cuz I'v been having this problem? Will this file stop the refreshing of the SIM when switching from tower to tower?
