after unlocking by anySim 1.02 all the iPhone functions are working fine except recieving the phone call. it says the connection error on the callers screen. any idea how to fix it?

you need to do a virgin restore (search the forum ) and then unlock again

Thanks for reply. Just to update the situation the incoming call is working fine with the other operators (2 of them) and just my existing provider says that it is not working because of the not sufficient unlocking.

Should i still try to re-unlock it?

if some sims work do not bother using the virgin restore method, it is most likelly a telco issue with the network and cannot be solved by you I suggest you start using one of the working sims as your everday network

This is not anysim problem or whatever. This is problem with your provider that has problems with iPhone! Many providers did have those in Europe. Siemens issued a patch for GSM centrals other companies also...

It was same with my provider until they applied the patch by Siemens!
