Sim card not valid on nokia 6680

If your Nokia C7 phone displays an error message saying "Insert Sim (or) Sim card not valid" then your phone is probably network locked.
To unlock it,visit the site OnlineGSMunlock.com here they are providing the unlock code at reasonable cost with easy step by step unlocking instructions and unlock it.Then you can use freely any GSM network Sim card.

Have you tried through Online sites???

Hi I'm a mobile phone Tech.

If your mobile phone is on a contract with a service provider, most of the times it will be locked in with them for the duration of the contract,
So if you try to insert a sim card from a different service provider, it may say "sim card not valid'
Try to insert your original sim card and see if that works.

Otherwise if this IS your original sim card and all of a sudden this message "sim card not valid" has appeared, then the sim card has gone faulty and you need to get a new sim card from your service provider eg... Vodafone.

Hope this is helpful

Hello

This error usually occurs when you attempt to use a SIM card from a network other than the network from which the phone originated (e.g. your Nokia mobile phone originated from Orange UK and displays the 'Sim Card Not Valid' error when you attempt to use a T-Mobile UK SIM card). The 'Sim Card Not Valid' error usually means the phone has been restricted for use on one specific network and you would need to unlock the phone before alternative network SIM cards can be used.

could You test the new SIM on another phone? Could be the housing of SIM damage on phone - hardware problem - Nokia Service.

in any case you need to find out which network and ask them for the unlock code.

Only the original network to which it is locked can provide this code.

sim not valid

HI,
ERROR:The sim card is not valid.
SOLUTION:
1.Check the sim card with another mobile.
2.Else,the sim card is not registered(which displays the message "sim is not valid") and we have to call customer care and tell them to register your sim card.

Plese help me with my N71, its sometimes show "insert SIM card" or "SIM card not valid". If you have ay answer please send me

Hi if it says that then the chances are that the simcard is blocked or not accepted on that phone so either try another sim card in the phone and also do you know what network the phone is on cus if you put different netwrok in it wont recognise the simcard
