If you want to change your telecom operator, but don’t want to change your current number, then Mobile Number Portability (MNP) is the best option for you.

How to make the switch?

1. First you need to choose your new mobile operator to which you want to switch. You should consider following things when choosing:

  • Network strength in your locality/city.
  • Types of available data and tariff plans.
  • Recharge denominations available.
  • Customer support.

2. Once you have decided your new operator, you are required to obtain a Unique Porting Code (UPC) for your number.

UPC is an alphanumeric code allotted by your mobile operator to all its subscribers, so that they can port their number whenever they want. For getting the code, you need to SMS PORT <Your 10 Digit Mobile Number> to 1900 – Normal SMS charge may apply.

3. One the message has been successfully delivered, you will receive your eight digit alphanumeric porting code along with its expiry date (in MM/DD/YYYY format) and time (in HH:MM:SS AM/PM format) from 1901.

After the expiry date and time, your porting code will become invalid and you have to request a new one.

4. Suppose you’d like to switch from AirTel (Donor Operator) to Vodafone (Recipient Operator), then you need to go your nearest Vodafone showroom/outlet and ask them to provide you with Customer Acquisition Form (CAF) and Porting Form.

Note: Don’t go to any normal recharge shop of your area, as they don’t have any authority to port your number. You should always go to authorized showroom of a mobile operator.

5. Fill in the porting form with following details:

  • Current mobile number.
  • Name of current operator.
  • UPC code.

You are also required to submit your passport size photograph, address proof and photo identity proof like driving licence, aadhaar card, voter ID card, PAN card, electricity bill, telephone bill etc. If you don’t submit correct documents, then your number will not be ported or will get deactivated after sometime.

Note: If you are a postpaid user, then you need to submit a PAID copy of last bill with the porting form and CAF.

6. The new service provider will charge you 19 INR as porting charge and will also provide you with a brand new SIM card.

7. If the information provided by you in the form and the documents are correct, your new operator will send a SMS to your Old SIM card number, intimating you about the Date and Time of Porting. This Date and Time indicates when your New SIM card will be activated and you can stop using your Old SIM Card.

Note: For all Indian states, a number is generally ported on the seventh working day after submitting the documents. But for some states like Jammu and Kashmir, Assam and North East, the number is ported on the 15th (fifteenth) working day.

8. There will be a No Service Period of 2 to 4 hours, which will begin immediately after the Porting Time given in Step 7.

No Service Period generally begins in-between 12 Midnight and 5 AM. Keep in mind during this period, all services will be deactivated on both SIM Cards.

9. Once No Service Period is over, you can replace your new SIM card with the old one.

10. You are now ready to enjoy services from your new mobile operator.

Important Notes:

  • A new number which is less than 90 days old will not be ported.
  • Under MNP, you can also switch from a CDMA operator to a GSM operator and vice versa.
  • The first digit in UPC denotes the operator, while the second digit denotes the circle.
  • Don’t share your UPC with anyone except with the agent at POS.
  • You can’t port a number from one state to another.
  • You have to again apply for DND (Do Not Disturb) after porting.
  • Any left over prepaid balance in your old SIM card will NOT be transferred to the new one.
  • You may also receive a call from your old mobile operator asking you to confirm the porting of number.
  • If your porting request is rejected, then you should ask your new operator the reason for rejection and then apply again after 15 days. New UPC can be generated once after every 15 days.
  • If you are a postpaid customer, then you have to pay the last bill amount to your old operator. If you don’t pay the amount, then your old operator will halt the porting process.
  • If you don’t receive your UPC or if you face any problem while porting the number, then you should contact your old/new mobile operator and ask them to sort out the issue.
