Invalid sim

If your phone displays the 'invalid sim' then your phone is currently locked to particular network. You need to unlock to use it with other network.
There can be many ways to Unlock your phone. As far as i know unlocking by codes is the simple and safe way. I will suggest the website which is doing good service and they were recommended highly in the cell phone forums.
I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.
