Hlo friends do u know u can change ur company of sim without changing phone number .So lets start:-
1: Send a message as PORT <space> Mobile Number to 1900 Eg: PORT 7777777777 and send this message to 1900. You will receive a UPC Code in message. Note it down. The UPC is valid for 15 days (30 days in case of J&K, NE & Assam Service Areas).
2: Now goto the nearest Customer service centre or the retailer of the operator you want to shift to and fill the Form and pay Rs. 19. In the form you have to mention UPC Code ( From Step 1). Submit your Identity, Address Proof and Photograph. For Corporate/Company connections a NOC is required for MNP, duly signed and stamped on the company letter head by the authorized signatory of the company along with the other documents.
3: The customer centre will give a empty sim, after your payment and document submission. With in 1 day you will receive an acceptance message to confirm the porting.
4: Change over takes place on the 7th working day (15th working day in case of Jammu & Kashmir, Assam and North East service areas). You will get an SMS from the operator with the date and time for porting. The service disruption time shall be around 2 hrs during night time of the date/time of porting.
5: Insert the new sim in your phone, Now you are in the new network with old number.
Once you ported to new operator, the minimum time to stay with the new operator is 3 months. So in this 3 months time you cannot port your number once again. Also MNP currently is possible only within your telecom circle Eg- MH circle number cannot be ported to KA circle, It can be ported from say Vodafone-MH to TATA-MH only.
I have gone through this process for both prepaid as well as postpaid connections and in my experience porting a prepaid sim card is the fastest and more easier than post paid.
