Unwanted signal vanish

My docomo on is 9529705352

i have ported my no before some days. Since porting, when i restart my phone it will not get signals for 2 to 3 min. After some time a message appears saying that 'sim updating' and all the singal vanish.

Signals will come back after 2 to 3 min.

My phone gets hang after this process.
