Insert correct sim card

Hi,
Please check the SIM card if it is correctly inserted or if you put in the SIM card the wrong way. But if you put in the SIM card correctly, you need to check your mobile phone if it is open to the network of the SIM card. If your mobile phone is unlock for all networks available in your country there is a problem on the SIM card. Please contact the network provider.
I hope I answered your question.
Thanks a lot!

go to a company store that your phone works with and tell them you would like an unlock code so you can use the phone abroad they should help you without a problem

the simply is u must go to ur nerest mobile care center and tell him to reset full factory setting by ufs box,infinity box or et box.

this erroe happens because the phone may be locked 
r else the gsm may not be supporting 
indian gsm and us gsm varies a lot check the gsm

MY FRND,
Don’t forget that which ever mobile you have purchase from the Outside of the India having the Network LOCK ….

So you have to remove the network lock by the mobile repairer…
