SOURCE: phone showing invalid sim
Is it a new handset? If so it will be locked into the network it was intended for, and if you are trying to use your old sim from another network/operator in this new phone, it will not work until you get the phone unlocked.
If you are saying the sim that came with the phone is saying "invalid", then you need to speak to the mobile provider about this.
If you have used the phone successfuly before & this has just started happenning, the only thing I can suggest is to take out the card, make sure the metal contacts on the card & inside the phone are clean, replace it & try again. If still no joy you may have been disconnected by your network.

make sure that its in correctly and wipe of the golden contacts off the sim and on the phone, if it still doesnt work you may need a new sim card
