I observed one weired problem with Lumia 800. Lumia 800 looses its signal for few secs once you end a call or Incoming call Ends.  If any one tries to call u during that time they are receiving message that you are out of coverage Area(But Actually you are incoverage). If person try to call you again then they will able to reach you.

I come to know about this problem when person telling me that they tried earlier but got a message that you are out of coverage and in next try they are able to reach me. This was reported in good coverage Areas. After that i observed in my phone when i end a Call coverage shows in single bar and within few sec it comes up as full bars.

Sounds like a sim card problem try getting a new one and see if it improves.
