If you are an Aircel subscriber and wish to port to Vodafone, here's what you should do:
1. Send an SMS to 1900 with PORT xxxxxxxxxx, where xxxxxxxxxx is your mobile number. You will get a message with a Unique Porting Code (UPC).
2. Visit a Vodafone outlet or dealer with the necessary documents like address and ID proofs and a passport sized photograph. You may also have to submit your Aadhaar.
3. You will be given a new SIM card, which will be activated only after the porting is completed.
4. The porting code you have received is valid for 15 days. The porting should happen within a week. At the most you it may take 10 days.
Once you lose the Aircel signal, insert the new SIM from Vodafone. Usually, the SIM pack has all the types of SIMS - normal, micro and nano. You will have to follow the instructions in the SIM card pack.
Alternatively, after getting the UPC (porting code) you can go to the Vodafone site here and give a request for porting. You will be contacted by Vodafone about the documents and photograph. You will get the SIM once you give the required documents.
