Sim card error on different phone - Cell Phones

You guys may not have the same cell phone provider, each company has a different sim card code.

Hi, have you tried using different Sim Card to check if the issue is related to Sim Card.? These issues happen due to Sim Card chip has damaged inside. If the same error displayed even after using working Sim Card, try to insert properly or the Phone's Sim Card Slot pins have not conducting properly to the Sim Card, in this case Service might be required to the Cellphone.

Chances are that the sim is corrupted. Get in touch with your service provider. You cal also try inserting a different sim to detect if its a sim error or phone error.

it is either your sim card or the phone try your sim in a different phone and if you get the same error then its the sim but if not and it works in a different phone then its your phone and it will need to be replaced

it turned out to be the sim card. I went to my nearest vodafone shop and got given a new sim card

Hi I'm afraid you can't. Pana A100 is very old model and was discontinued in 2004. It had support for 2G SIM cards (3.5V) meanwhile most new SIMs are 3G and/or with different voltage (1.8V).

Hi thee, I list here the possible reasons for "Sim card not valid"

1 - The phone is locked to a different network. In this case the phone usually accept the sim card the same , and has no network, but sometimes it may return the error message. Unlock the phone at a local shop.

2 - the SIM card is faulty. Test the card on a different phone to find out.

3 - The phone is faulty. Test the phone with different Sim cards, if the Phone returns same error on all cards, then the phone is faulty.

Your sim card is crashing you will need to replace sim card

have to get the phone unlocked, imeicheck.com
