My 5S cannot make or recieve phone call
I have a 5S, about 2 years old and I cannot make or receive phone calls. I have asked my operator in Sweden and Thailand and I´ve been in a Apple store in Thailand. The best they can offered is to change my IPhone to a new for a cost of 17000 bath, 4000 SEK. I am not interested in pay this kind of money but can pay for reparations if it´s not this kind of costs.
Please help
