Hi! This is urgent and extremely important. I have an acquaintance whom I met last Wed afternoon in Delhi . We got our SIMs from Delhi. Problem is I did not save his phone number correctly. Instead of saving his cell phone number, I saved his SIM SERIAL NUMBER thinking that was his cell phone number.
I even spoke to SMART Communications but nothing happened. Apparently they do not keep info on prepaid customers.
Is there any way I could find my contact's cell phone number from the SIM SERIAL NUMBER?
Is this a lost cause? :(
This is really important! I do not have any other form of communication with him. He is originally from the US.
Any help would be appreciated.
Thanks.
