Am I liable for the mobile service contract signed by my friend who used my ID?
My friend used my civil ID to order a mobile phone from a mobile company. It is payable for six months.
She paid 2 months but the mobile got broken and she asked replacement from the company. The company took the phone but did not give any replacement thus my friend did not pay her outstanding balance.
Now they are calling me asking me to pay the balance and penalty. Why am I going to pay penalty and balance where in fact the mobile is in their possession?
Am I getting sued for letting my friend use my ID? Note that I didn't sign any papers from the company. They are threatening me that if I will not pay they will send police to arrest me.

Based on the documents, you own the mobile and you have to pay the delayed payments.
I don't understand what do you mean by penalty, if it's written in the contract which your friend signed with your civil ID, then you have to pay it.
You have to get the mobile back since you are paying/going to pay the late payments.
Even if you didn't sign, but based on the papers they have & your civil ID, to them - you signed.
Your friend may get sued and you too since you know that he/she is taking this action.
I recommend you to pay and get your mobile back and NEVER EVER let anyone use your civil ID.
