Switching from Airtel Prepaid to Airtel Postpaid has become easier than ever. Airtel now offers doorstep KYC, free SIM delivery, faster activation, and premium postpaid features for users who want uninterrupted service. This guide explains the full Airtel prepaid-to-postpaid migration process in simple language.
In this article, you will learn the step-by-step process, required documents, benefits, plans, FAQs, and expert tips to make your migration smooth and fast.
What is Airtel Prepaid to Postpaid Migration?
Airtel prepaid to postpaid migration means converting your existing Airtel prepaid number into a postpaid connection. It allows you to use the same mobile number while enjoying monthly billing and premium features.
The migration is simple and usually takes only a few hours once KYC is completed. You do not need a new number or a new SIM unless your SIM is old or damaged.
Airtel provides both online and offline options, giving flexibility as per your convenience.
Why Should You Switch from Prepaid to Postpaid?
Airtel offers several premium features exclusively for postpaid users. These include unlimited calls, high-speed data, family plans, and OTT subscriptions. You also get priority customer care and better international roaming options.
Postpaid users enjoy seamless network quality, especially during peak hours. You also avoid the hassle of frequent recharges because billing happens only once a month.
For heavy data users or family connection users, postpaid is often more cost-effective compared to prepaid.
Requirements for Airtel Prepaid to Postpaid Migration
You must meet a few basic requirements for successful migration. These include valid KYC documents and the same Aadhaar details that were used for your prepaid SIM.
Make sure your mobile number is active and working during the verification process. Also, your existing SIM should support 4G or 5G services for faster activation.
If your SIM is too old, the technician may replace it with a new 4G/5G SIM during doorstep delivery.
Documents Needed for the Migration Process
Airtel requires KYC verification before converting your connection. The most commonly accepted document is Aadhaar, as it allows instant verification.
You may also provide Voter ID or Passport if Aadhaar is not available. However, Aadhaar makes the process significantly faster.
Ensure your document details match your current mobile number ownership records to avoid delays.
How to Apply for Airtel Prepaid to Postpaid Migration Online
Airtel provides a convenient online application process through the Airtel website and Airtel Thanks app. The online method is quick and requires only basic details such as your mobile number and address.
Once you submit the request, an Airtel executive will contact you to schedule doorstep KYC. After verification, your postpaid service will be activated within a few hours.
Online migration is ideal for users who prefer hassle-free doorstep service without visiting any store.
Steps to Convert Prepaid to Postpaid from Airtel Website
Visit the official Airtel website and go to the postpaid section. Enter your mobile number and address to place the request. Choose a preferred plan from the available options.
Airtel will assign a technician who visits your location for KYC. The SIM (optional) and plan are activated after verification.
The entire process is safe, secure, and handled professionally by Airtel staff.
Airtel Thanks App Migration Method
Open the Airtel Thanks app and navigate to the “Manage Services” section. Select your prepaid number and tap “Upgrade to Postpaid.” You will see all available postpaid plans.
Choose a plan and confirm your address details. Airtel will send an executive for KYC based on your schedule.
This is the fastest process because your details are already synced with your Airtel account.
Offline Method: Visit the Nearest Airtel Store
If you prefer personal assistance, you can visit any Airtel store. Store representatives will guide you through documentation, plan selection, and KYC.
You need to carry your Aadhaar or other valid ID for verification. The process usually takes 15–20 minutes.
Your number will be migrated to postpaid within a few hours after completion.
Doorstep SIM Delivery and KYC Process Explained
Airtel offers completely free doorstep SIM delivery for users applying online. An Airtel executive visits your home or office for KYC and SIM handover.
The executive uses a biometric device to verify your Aadhaar instantly. Once done, your postpaid SIM is activated and ready to use.
Doorstep delivery is available in most major cities across India.
What Happens to Your Existing Balance and Packs?
If you have an active prepaid balance, it usually lapses during migration. Airtel does not transfer unused balance or data to postpaid.
Make sure you use your prepaid benefits before initiating the migration request. Once the postpaid plan activates, your old packs are automatically removed.
Your billing cycle starts immediately after activation.
How Long Does the Migration Take?
In most cases, Airtel completes prepaid to postpaid migration within 30 minutes to 4 hours. However, if you are in a remote area, it may take up to 24 hours.
The speed also depends on your KYC verification. Aadhaar users get instant activation, while other documents may take longer.
Your number remains active throughout the process.
Benefits of Airtel Postpaid Plans
Airtel postpaid users enjoy premium data speeds, unlimited calls, and special OTT subscriptions like Amazon Prime and Disney+ Hotstar (depending on the plan). Family add-ons help save money for multiple users.
You also get rollover data, which means unused data is carried over to the next month. International roaming benefits are also included in higher plans.
Postpaid users receive priority access to customer care for faster resolution of issues.
Best Airtel Postpaid Plans for 2025
Airtel currently offers multiple postpaid plans based on various user needs. The most popular plan is the ₹499 plan with 75GB data and OTT benefits.
For families, the ₹599 and ₹999 plans are ideal, offering multiple connections under a single bill. Heavy data users can choose higher-tier plans with more data and add-ons.
Choose a plan that fits your calling, internet, and streaming requirements.
Does the Number Remain the Same After Migration?
Yes, your existing mobile number remains unchanged. Airtel only changes your billing type from prepaid to postpaid.
All your contacts, linked accounts, and OTP services continue without any disruption. You do not need to inform banks or apps about the change.
This is one of the major advantages of choosing migration instead of buying a new SIM.
Common Problems During Airtel Migration
Some users face delays due to mismatched documents or old SIM compatibility issues. If Aadhaar details do not match Airtel records, verification may fail.
Network issues can also delay activation in remote locations. Make sure your phone is switched on and receiving signal during the process.
Contact Airtel customer care for any technical or verification-related issues.
