If you are having Aircel network problems and would like to port to Airtel, follow these steps:
Send an SMS to 1900 with the word Port. It must followed by your mobile number. It will be like this: PORT xxxxxxxxxx. You will get a confirmation from Aircel with a Unique Porting Code (UPC)
Visit the Airtel office or dealer near your location. Submit documents like address and ID proof with a photograph. You may also have to submit your Aadhaar.
You will get a new SIM card from Airtel, which you must insert only after the porting is complete.
The code you would have received from Aircel is valid for 15 days. The porting should happen within a week. At the most you it may take 10 days.
If you are already not getting the Aircel signal , insert the new Airtel SIM in your mobile and keep checking for network.
If you are lucky enough to be one of the few to be still getting the signal from Aircel, you will have to wait till you lose the network signal.
Once you lose the signal, remove the Aircel SIM and insert the Airtel SIM. The single SIM will have all types of SIMs - Nano, micro and full SIM. Snap out the SIM that fits your phone and insert it in your mobile.
You will have to dial a particular number to activate the connection. The executive may ask the details you have given in your porting request - like your address.
