Yar sim card rejected


There may be various reasons for it.
1) Your SIM card might be damaged. Check inserting the SIM card in any other active unlocked phone.
2) The SIM port on the cell phone might be damaged. Check inserting any other active SIM card to your phone.
3) The cell phone might be network restricted. Try inserting any other network's active SIM card to it. If the device reject that too, then you need to unlock the phone. You can unlock a Nokia C1-01 safer and easier using unlock code. You can get the accurate unlock code for a Nokia C1-01 from TheUnlockArena.com at affordable cost. Good luck.

Sim card not valid


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.

I put the sim card in and it says insert sim card


Hi, when a phone says insert Sim,is either the Sim card or the Sim seater that allows the Sim to work is bad.

First try the Sim card on another phone and see if it will display insert Sim again.If it display that means the Sim card is damaged. But if no display,that means the Sim tray of your phone is damaged and will need to be replaced.

Contact a skill prsonnel.
Take care.

INSERT SIM


If the display says "Insert SIM," it means that the phone has no contact with your subscription card (SIM card) that is inserted in the phone. We recommend that you remove the battery and the SIM card, and clean the connectors on the SIM card and the phone with a soft brush, cloth or Q-tip moistened with any type of unflavored colorless alcohol.
At the same time, check that the card is not damaged or worn in any way, in that case, the connector may not align with the connector in the phone. Please contact your operator / carrier for a new SIM card.
