Question about Samsung Cell Phones
I think it is the problem with SIM card. Please try to insert the SIM card in another phone and you may be getting same error or messages like 'SIM card not valid'. If this is the case rquest a SIM replacement from your provider

SOURCE: I brought Samsung GT S-5230
If your phone displays the 'Insert correct simcard' 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 Unlock-zone.com 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.
