Help My s2 fail to detect sim card at times!!

[wengyew90]

There are some times when i find that my s2 fail to detect my sim card especially after the battery die on its own. When i connect the charger and power it on, there is no prompt for my sim pin.

I try to reboot my phone, which usually works, but it may take up to 3 times (worse case) before it is able to detect it. At other times, it may suddenly prompt me for the sim pin if i press the home key.

Anyone could provide me with an assistance to overcome the issue (other than keep rebooting) ?

Thanks
