Hello sir. my micromax X225 invalid sim problem. so please help me sir


You need a SIM from the carrier that owns the phone. Usually they are on contract and locked to that carrier.

Also when someone tries 3 times to unlock a phone unsuccessfully, the SIM becomes locked. If you try 10 times with the wrong code, the SIM becomes invalid and must be replaced with a new one. This is particular help when a phone is stolen or lost. Only the carrier can unlock the SIM or replace it. Phone your cellphone carrier/provider.

INVALID SIM


This may be because of your damaged SIM. Try the following:
1. Check whether your SIM is rejected by just putting the same SIM in another phone. Also, check if your SIM is a valid GSM compatible SIM.
2. Check if that your phones SIM slot is fully operational.
3. Check if you have correctly inserted the SIM.

Hope this may help you. Happy New Year to you too.

If the Phone says Invalid Sim means it locked to Network ,You need to Unlock it...get the Unlock code from the site Superunlockcodes.com and get the Free unlocking instructions at here Mobileunlockguide.com/nokia-5130 and Unlock it step by step....That is Nokia 5130 not S5130,there is not model like that in Nokia.

PUK stands for Personal Unblocking Key. This is a uniqueeight-digit code specific to your SIM card. This is required when the PINnumber to unlock your mobile phone is entered incorrectly 3 times. You are thengiven 10 attempts to enter your PUK code. If an incorrect PUK code is enteredafter the 10th attempt, you will block your SIM card permanently and willrequire a new SIM card from your mobile phone provider.
PUK codes can be obtained through the following ways -The PUK code is in your SIM card documentation Starter Pack.If you do not have this then -Please contact your phone service provider.
Your cell phone service provider can give you the PUK code once you give themyour account details and they have confirmed your identity.For details to obtain the PUK code for the SIM card, pleaseclick on this link and follow my instructions.
