'sim card not valid' when i do insert my sim card.what might be the problem ?


Hi,
Your phone may be locked to its Network, that's why it shows "sim card not valid". In order to use other Networks, you need to unlock your phone. You can unlock your Nokia N70 using code.You can either get the unlock code from your service provider or from reliable online site. Superunlockcodes.com is where i unlocked my phone, they offered codes at affordable price, with simple unlocking instructions.

If the phone displays the message "PHONE FREEZE. SIM UNAVAILABLE PLEASE CONTACT YOUR SERVICE PROVIDER" then your phone has got hard locked. You need to unfreeze the phone to get unlocked. You can get the unfreeze code, unlock code through online..........give your IMEI number and get the unlock code for ur mobile.... i will suggest the website TheUnlockSpot.com which is doing good service .....you can approach this website.

My nokia 7230 shows a restricted code when m using any sim card .. how can i use my phone?


nokia 7230 it will say "sim card registration failed" no signal. cant make any calls. take the battery and sim card out and put it back in and the error message is GONE and works again. signal is back and can make calls. thought it might be something wrong with the sim card. did a sim swap. still does it. EVERYTIME i get that message and take the sim card and battery out and put it back in it works FINE. something wrong with the phone right? bought it in may this year.

My sim card is blocked


Hi
Any sim card has a pin code(4 digits). Sometimes it is activated some times not. If you put in the pin code 3 times wrong, your simcard willl be locked. To unlock it you will need a PUK code which is a 13 digit number. You usually get it at the same time with your sim card. If you put in the PUK code wrong 10 times then you won't be able to use it anymore and have to contact your Net provider to get a new Sim card.
