To convert your existing Aircel Postpaid SIM to prepaid,
- Pay the bill due in advance before one week. For example if your billing cycle ends in 31 st of this month, then pay this month bill before one week around 23rd or 24 th of the month. Otherwise Aircel executive will tell you that you have bill dues, so you cannot change your plan to postpaid to prepaid.
- Now with an id/address proof xerox , a passport size photo , visit nearest Aircel show room. The showroom should be inside the circle where the SIM card was bought. For example, if you bought the SIM in Tamil Nadu circle, then you have to visit Aircel show room in TN circle only, Chennai circle showroom will not help you.
- The representative will accept your request and collect the proof and photo.
- Your application request will be verified and your existing Aircel Prepaid number will be converted into Postpaid number within 24 hours.
If you have Aadhar number, then the process is simple and you can verify your identity using bio-metric sensor. Photo, address proof are not needed for Aadhaar verification.
