With deep respect, I am a regular customer of Samsung phones. Been using this phone for 10 years now without any problem, but now there is a problem - after changing the ownership of a sim now the handset is showing network problem. "Access point names are not available for this user" appears. The SIM is being used in other mobile phones, but I want to use it in this phone. Request your help to solve my problem.
As per your query, we want to inform you that this is the concept of the devices, However, kindly contact your network service provider they will provide you with the exact information regarding this.
