Have you updated device recently as mention "phone updation" in title? Have you tried another SIM card?
This issue could be result of either a software issue or SIM card holder itself becoming detached from motherboard.
Can be worth re-flashing device software although be aware that talk.maemo.org having to relocate servers at the moment;http://discussions.nokia.com/t5/Maemo-and-MeeGo-De
It may be worth trying the"packing trick" to improve contact of SIM to holder contacts and also press soldered joints down onto motherboard:http://talk.maemo.org/showthread.php?p=1147506 and http://talk.maemo.org/showthread.php?t=82583&page=
