This is a Russian carrier and my sim is about 7 years old.

You need to switch off your iPhone BEFORE removing the sim. then place it in another phone, make a call and again switch off BEFORE you place your sim back to your (switched off!) iPhone. Only then reboot your iPhone. This should hopefully do the trick!

For me this work around is consistently working fine. Here is the only solution / workround to the no Service problem, Switch IPHONE OFF, remove sim and place in a working phone, boot up and place a call to any number eg answer phone, switch off phone place in Iphone boot it back up and within 30 seconds full signal and service provider, warning this needs to be done everytime you switch off, I know it is no ideal but until a fix is issued this will get you working.
