Question about Nokia 6300 Cell Phone
Posted by Anonymous on
If your Nokia 6300 phone displays an error message saying "Invalid Sim (or) Sim Registration failed" then your phone is probably network locked.
You can unlock it easily by using an unlock code.You can get this code at reasonable cost from TheUnlockArena.com with easy step by step unlocking instructions and unlock it.Then you can use freely any GSM network Sim card.

There are two things causing this problem,either your phone is not registered to the Sim card's network or your Sim card is corrupt
To find out where the problem has come from,you should try another Sim with your phone, if the Sim does not work then the phone is registered to a particular network and no other Sim card will work on it.
If you try another Sim card and it works then your Sim card is corrupt and you should replace it.but to be double sure,test the Sim card on another phone to see if it works,if it does then your phone is not compatible with the Sim card's network but if it does not work then your Sim has to be changed
