Operators has started the process of implementing simplified dialing pattern that allow both STD and local numbers be dialed without any prefix. Many operators have implemented this .
One of the main technical problem of full MNP was STD dialing pattern. At present, STD numbers can only be dialed by adding either ‘0’ or ‘+91? as the prefix. But post full MNP STD and local numbers cannot be differentiated and should have same dialing pattern. These changes require configuration modifications in each of the operator nodes and operators had sorted more time to implement this before full MNP. DoT had recently given two months extension for operators to implement full MNP on grounds of these technical issues.
As per the latest deadline set by DoT, full MNP will be implemented in the country by July. A full MNP will allow the subscribers to move from one mobile networks to other in any telecom circles in the country. So customer can retain his mobile number in any part of the country without paying for roaming charges.
