Can't Activiate my new iphone 5S (SIM IS NOT VAILD)

Hello,



I have recently purchased a new iPhone 5s from a Company here in UAE ! and sent the iphone new as it's to as a gift outside the UAE ! when they tried to activate their iphone for the first time ! it gives them the error that SIM is not valid !



I contacted the company they said they can't do anything about it ! and Honestly they hardly understood the problem !



Is there anyway to activate the iphone without bringing it back to UAE ? and if I find an SIM card for the same carrier there will it help to activate the iphone ?

or is there anyway that can bypass it without affecting the originality of the iphone ?





Thanks
