My phone stopped recognizing my sim card.How do I get my phone to recognize my sim card again?


You can try doing a system reset. Shut off the phone. Remove the battery, & the SIM card. Press any buttons on it around 5 times to discharge any remaining voltage in the phone. Allow the phone to sit for 5-10 minutes to allow any traces of power left to drain. Place the card & the battery back in, & turn on the phone. If the phone is undamaged, it will restart & re-initiate itself without losing any of your files.

My pantech is brand new. it worked fine when i first got it but out of no where it keeps saying insert sim. my sim card is already in it. what do i do? this is the secound time this has happened.


Try removing the SIM card and clean the contacts on the SIM card and the cell phone with ethyl alcohol, then replace the SIM card. This will make sure the SIM card makes proper electrical contact.
If this does not work the the SIM card may be faulty, you need to contact your cell phone provider for a replacement SIM card.

Pantech C520 is a very temperamental phone and without the handset in front of me I can only give you a few things to try.

Pull out the SIM card and clean the contacts on both the card and phone. Lightly rub the contacts using a pencil eraser. Replace the Sim card and battery, try to make a phone call. If that did not work place the SIM card into an unlocked phone. Working in this phone then either your handset need to be reset (master) or is broken. Not working in the unlocked phone means your Sim card is bad and need to be replaced.

My pantech matrix cell phone says insert sim card


This problem arises sometimes because the mobile is unable to read the SIM. May be you should fold a small piece of paper in the same size of the SIM and keep it on top of the SIM and then insert the Battery. I think this will solve your problem.

My sellphone get block and now said insetrt sim but the card is there an dstill said the same thing?


First, make sure you have the SIM inserted in the phone correctly. If you do - and the phone still doesn't recognize the SIM card - you may need to replace the SIM card.

This is a common problem with some phones especially when the SIM has been transferred from one phone to another.

Just about the only way to correct it is to replace the SIM card with a new one.

You can purchase one on eBay for a few dollars instead of paying $25 at a retail outlet. Once you receive it, carefully pop it out of the card it is attached to and correctly insert it into your phone.

Put in your battery and turn your phone ON. You should see a 'No Service' message on the screen. If you do, then your phone can now recognize the new SIM card.

Look on the larger card you removed the SIM from and get the SIM number from the card. Then call your service provider and inform them you have replaced a defective SIM card with a new one in your phone. Give them the new SIM card number and in less than 1-minute your phone will be working again.

When it does, the message on the screen will change from 'No Service' to the name of your cellular provider.
