Triple play service provider’s ( Worldcall,Nayatel,Wateen & Mobilink infinity) mostly Phone Numbers are not recognize or identified when someone call from PTCL & Vfone Network to these other network( disconnect tone or number not in use message ).

Some of my friends also inform me the local call charged by PTCL & Vfone as NWD Peak-time call even they are in same city (less than 25Km Distant) when ever they call on others networks from PTCL.
