Facts about MNP:
MNP is always a government regulated body that implements the solution and keep track and record of port-in and port-out numbers among operators. A centralized MNP server and "Centralized database" is maintained by MNP body and accessible to all operators.
There is always one "Donner" (subscriber port-out) and "Acceptor"(subscriber port-in) operator in MNP topology Tehnically speaking IMSI and MSISDN are network dependent and can not be cross-mapped.
Therefore if any MSISDN port-out to other operator, recepient operator assigns new IMSI, MSISDN, ICC-ID, that is new SIM card is allocated to subsciber with similar MSISDN but with IMSI ICC-ID of new operator.
All operator update the MNP database againt this subscriber and also update the routing table in MSC with " LRN". LRN is alpha numeric prefix appended before the MSISDN and is specific to each operator and plays key role in MNP.
Number Portability Clearinghouse makes it easy for mobile operators anywhere to comply with number portability mandates. It serves as a centralized system for porting all number types(CDMA/GSM).
In the number portability the major roll is of STP (signaling Transfer Point). STP will have the local database server of the operator and it will in sync with the central database handled by the DOT and TRAI in india.
In INDIA, MNP is controlled(Nothing but Number Portability ClearingHouse) in joint venture with TELCORDIA (Number Portability - Telcordia - Number Portability Clearinghouse)
Whenever any subscriber want to change the operator he will buy on SIM card and acceptor operator will route(map) the IMSI with the subscriber MDN and same will be updated in the central database. Local database server of accepter and donar network will take the update from the central database.
Once the subscriber will moved from one operator to other operator he has to stay with the new operator for minimum of 3 months(90Days) as per the MNP guidelines provided by the TRAI.
How Mobile Operators SUCKING BLOOD while PORT-OUT their subscribers:
1) When you send a MNP request to get UPC by sending SMS to 1900, then immdtly your Existing operator's retention team calls you & tries to convince you with new (hidden) tariff plans which is especially made for MNP Switchers.
2) If you didn't convinced by retention team's offers & you still want to PORT-OUT, then your existing operator try to REJECT your MNP request by giving any S.H.I.T.T.Y reasons.
VALID REASONS:
i) Number is less than 90 days old.
ii) PORTing code(UPC) mis-match
iii) Requested no.'s service provider is NOT within the same service area.
iV) Un-Paid dues in case of Postpaid & negative Balance incase of pre-paid.
v) Subscriber's name mis-match
INVALID REASONS:
i) Subscribers under LifeTime validity.
ii) NOT enough positive balance(incase of prepaid).
iii) If your number is FANCY one, then they might ask you for PREMIUM NUMBER allotment charge while approving your PORT-OUT(I personally experienced this issue with my Fancy number).
POST PAID SUBSCRIBERS, BEWARE OF THIS:
Even if you clear out all your dues(generated bills), still operator's billing system shows your account is with DUEs. Its because of your unbilled amount.
So, its your duty to call your existing operator & ask for your unbilled amount & add next 10days approximate usage amount to it & Pay the same before you submitting your PORT-IN request to NEW operator. Else your PORT-OUT request will be REJECTED by your existing operator with VALID REASON. DONT TRY TO SETTLE THE UNBILLED AMOUNT WITH YOUR DEPOSIT AMOUNT(if any) with your existing operator. Because once you PORTED-OUT Successfully, you have the rights to ask your OLD operator to REFUND your DEPOSIT. So DONT mess with DEPOSITED AMOUNT while PORTING-OUT.
PRE-PAID SUBSCRIBERS, BEWARE OF THIS:
Cancel all VAS like Caller Tunes, SMS Subscription Packages(NEWS, Jokes..etc..). Try to maintain your pre-paid balance above Rs.20 till you receive the confirmation SMS from your existing operator regarding successfull approval of PORT-OUT request. Else some of VAS subscriptions may consume amount on regular basis from your existing balance & your operator may REJECT your PORT-OUT request by giving reason as 'Negative/Low Balance'.
FOLLOW THESE STEPS TO MAKE YOUR MNP SWITCHING SMOOTH:
1) Follow the TIPS given above separately for PostPaid & Pre-Paid users.
2) Dont mess with "Retention" calls from your existing operator. Handle them smoothly & reject their offers even more smoothly. If still retention team gives you more tention, then just tell them that "My mom & dad/bro/sis got 2 more your connections with postpaid & if you people didnt stop your retention calls & didnt approved my PORT-OUT request, then I will ask my mom/dad/bro/sis too apply for PORT-OUT from you".
3) Once you submitted your PORT-IN request to new operator along with all necessary documents, just relax for 3 days. On 4th day, call to existing operator & as well as new operator's customer care & ask for MNP status for your number.
4) On 5th, 6th & 7th day, Call & write an email to your existing operator's NODAL Officer & request them to PORT-OUT your number & also tell them that 'customer care people are NOT helping you much, so you writing to them'.
5) On Day7, get in touch with new operator & keep on asking for the status of your PORT-IN request.
DONT GET PANIC IF YOUR MNP REQUEST GOT REJECTED BY YOUR EXISTING OPERATOR, STILL YOU CAN RE-REQUEST FOR MNP AFTER 15days from the date of UPC Generation.
