The backbone of the horizontal approach is a standalone Number Portability Gateway (NPG), a central database which carries the Local Routing Number (LRN) of all mobile subscribers in the country. The LRN is a 4-digit unique number which represents a particular network. For example if the LRN of Mumbai MTNL is 1234, all mobile subscribers of it will have the LRN 1234, irrespective of the porting status of the number. In other words, if a mobile number gets ported, the call routing is accomplished by changing it's LRN to that of the recipient operator.
I will illustrate this with an example. Let's consider a random fictional guy: plumber Mukesh Ambany with the mobile number 9999100100. He is using Reliance GSM network in Mumbai which let's say it has the LRN 5678. Now he wants to change his subscription to MTNL (LRN=1234) because of any of the reasons I cited above, or may be because he has some differences with his brother in allowing mutual competition and selling of shares before offering to each other, whatever that means. Anyway currently whenever another random guy called Anil make calls to him (or anybody for that matter), the call is diverted from the
Scope of MNP in
I will do a point-wise approach in this section.
The fors:
1. The subscriber gets to change his operator without changing his number, which may be important to him.
2. There is scope for more even competition at the market, because operators will have to satisfy the subscribers so that they won't leak out. The statistical figures of MNP may have to be made public, which will expose the operators whom the subscribers are deserting and that won't be a good advertisement.
3. A trivial one. MNP is implemented in a large number of countries and
The againsts:
1. MNP implementation and testing are very cumbersome exercises, especially in
2. Its not possible to port a number to a operator in another circle. While that decision makes sense, because that would complicate call routing and billing, for people changing their numbers when they travel to other cities for long duration, MNP is totally useless.
3. MNP's impact has been minimal in most of the countries. According to a report in Voice n Data, "Around the world, MNP has been a mixed bag of success and failure... While it has worked in markets like Hong Kong and
4. I would analyse the key causes of MNP failure as found by Analysys: The high charges involved with transferring numbers, long delays in the process, and a sheer lack of awareness that MNP is available.
a. High charges: In
b. Delays: The porting delay is expected to be at most 84 hours in India, as per the directive, which itself is too much of time, considering the porting time in other countries: 2 hours only in USA, as low as 20 minutes in the Republic of Ireland, 3 minutes in Australia and even a matter of seconds in New Zealand.
c. Lack of awareness: As per a survey by Nielsen India, 18% of Indian mobile customers said that they would change their operator if they have the ability to retain their number. A quarter of Reliance and Tata said they would change their operator post-MNP. That’s huge.
The important fact however is that 17% of all Indian mobile customers were planning to change their operator pre-MNP itself. (Refer to the comparison chart) That means an increased interest of just 1%. The 17% people would very well throw away their current SIM and get another one of their preference, like they have been doing before MNP rollout. This is another factor. How many people love their number so much that they would prefer to go through the lengthy porting procedure instead of getting a new SIM and letting others know of the new number by SMS or something? As far as publicity is concerned, MNP has been in news for quite some time due to the lengthy and often postponed rollout procedure; so many people already should have heard of it. Idea has already started airing ads on MNP asking people to "switch to Idea", making it to look like a service they are offering. BSNL went one step ahead by offering stuff like free talktime to people porting in. Good strategy, I'd say. But speaking of the MNP scenario in the USA, Analysys states that "most top tier carriers hopped on the MNP advertising bandwagon when the concept was first introduced in 2003 but hopped back off almost as quickly. Since advertising the MNP option didn't make a major impact on consumers' decisions to port their numbers most carriers decided they would rather spend their budget advertising new phones and price plans." That is exactly what is going to happen in
Obviously the cons outweigh the pros. I have been working closely with an operator for MNP implementation and testing, and I have to say that the time, money and manpower spent on MNP is not worth it. TRAI should have done enough feasibility studies to understand the massive effort the whole rollout would require in a unique case like India with about 300 operators spread in 23 circles and the possible impact of the service. I'd like to wind this up with a quote by Colonel (retd), S. N. Aggarwal, a Delhibased consumer activist. "MNP is going to be a mess. There is absolutely no coordination between TRAI and the operators."
