A mobile recharge used to mean a trip to the corner shop for a scratch card. Now it's a few taps in an app: enter the number, pick a plan, pay by UPI or card, done. It's quick enough that people rarely think about it, which is exactly when mistakes happen: a digit typed wrong, a plan with a shorter validity than expected, or a "free recharge" link that turns out to be a scam.
This guide walks through recharging a prepaid number online, from choosing where to recharge to checking it worked, with the rules India's telecom regulator, TRAI, sets for how plans are sold and confirmed.
Prepaid or postpaid?
Recharging applies to prepaid connections: you pay first, then use. A postpaid connection works the other way: you use the service and pay a bill afterwards, so there's nothing to recharge, only a bill to pay. If you're not sure which you have, the SMS your operator sends after any recharge or bill will tell you, and so will its app. Our guide to prepaid vs postpaid explains the differences in detail.
Where you can recharge
You have several options, and they all end at the same place: your operator activating the plan on your number.
| Where | How it works | Worth knowing |
|---|---|---|
| Your operator's own app or website | Log in with your number, choose a plan, pay | Shows your current plan and balance; plans are always current |
| UPI and payment apps | Pick mobile recharge, enter the number, choose a plan, pay | Some route recharges through Bharat Connect (BBPS), which lists mobile prepaid as a bill category |
| Your bank's app or net banking | Use the recharge or bill payment section | Paid straight from your account |
| A shop or agent | Give your number and pay cash or by UPI | Ask for the confirmation SMS before you leave |
Bharat Connect is the name NPCI Bharat BillPay (NBBL) now uses for Bharat BillPay, the platform behind the Bharat Bill Payment System (BBPS), and its list of categories includes mobile prepaid and postpaid alongside electricity, DTH and FASTag. Our explainer on BBPS and Bharat Connect covers how it works.
Step by step
The flow is the same in almost every app:
- Enter the mobile number carefully, or pick it from your contacts. Check every digit before going further.
- Confirm the operator and the circle (the telecom region). Apps often fill these in automatically; correct them if they're wrong.
- Choose a plan. Read the validity, data, calls and SMS benefits, not just the price.
- Pay by UPI, card, net banking or wallet, and approve the payment.
- Wait for confirmation: a success screen in the app and, more importantly, an SMS from your operator.
Reading a plan: TRAI's voucher types
TRAI's consumer protection regulations allow only a few kinds of prepaid voucher, and every plan you see is one of them, whatever the operator calls it:
| Voucher | What it does | Rules worth knowing |
|---|---|---|
| Plan voucher | Moves you onto a tariff plan | Gives no monetary value of its own |
| Top-up voucher | Adds talk-time money (monetary value) to your account | No restriction on its validity or usage; operators must offer at least one ₹10 top-up |
| Special tariff voucher (STV) | Gives benefits such as data, calls or SMS for a set validity | Validity can't exceed 365 days; operators must offer at least one STV for voice and SMS only |
| Combo voucher | Combines benefits with some monetary value | Must show its validity and the monetary value it adds |
Most "recharge plans" on apps are STVs or combo vouchers: a bundle of data, calls and SMS for a number of days. The validity is the most important detail, because when it ends, the benefits end. TRAI amended its rules again in September 2026 to require voice-and-SMS-only vouchers at every validity of 30 days or less that operators offer for data plans, plus a voucher that renews on the same date each month; the change applies 30 days after publication in the Official Gazette.
What confirmation you should get
TRAI's regulations require operators to send you an SMS immediately when a voucher is activated. For a special tariff voucher, it must state the amount charged, the validity and the benefits; for a top-up, the amount charged, any processing fee, taxes, the net value added and your total balance.
That SMS from your operator is the real confirmation. An app's "success" screen tells you the payment went through and the request was accepted; the operator's SMS tells you the plan is actually on your number. If you got the first but not the second, see our guide to recharges that failed or didn't arrive.
Recharging the wrong number
This is the mistake people most want to undo, and the hardest to fix. A recharge is delivered to whatever number you enter. Once the operator has activated it, the benefits sit on that number, and there's no general rule that obliges anyone to move or refund them.
- Contact the app or website you used, and the operator, straight away, with the number, amount, time and transaction reference. If the recharge hasn't been processed yet, it may be possible to stop it.
- If the wrong number belongs to someone you know, they can simply use the plan.
- Prevention is the only reliable fix: pick numbers from your contacts, and read the number and operator on the confirmation screen before you pay.
If the payment fails or the recharge doesn't arrive
Two different things can go wrong, and they follow different rules. If your payment failed after money left your account, your bank must reverse it under RBI's rules on failed transactions: for a UPI payment to a merchant, within five days. If your payment succeeded but the recharge failed, the money is with the app or merchant, and getting it back is a refund, which a payment aggregator must send to your original payment method unless you ask otherwise.
Our guide to mobile recharge failed but money deducted walks through both cases, how to check a recharge's status, and how to complain.
Staying safe
Recharges are a favourite lure for fraudsters, because everyone needs one:
- Recharge only through your operator, your bank, a well-known UPI or payment app, or a shop you trust.
- Ignore messages offering free recharges or huge discounts through a link. They're usually phishing for your card details, UPI PIN or OTP.
- Never share an OTP or your UPI PIN with anyone who calls about a recharge, a SIM upgrade or a KYC update.
- If you pay by UPI, read the payee name before entering your PIN.
Our guide to UPI fraud covers the common scams and what to do if money goes.
Why it pays to keep your number active
If you don't use a prepaid number at all, TRAI's rules let operators deactivate it for non-usage, but not before 90 days, or a longer period the operator sets. If you have more than ₹20 in your account, the operator can't deactivate the number for non-usage; instead it may deduct up to ₹20 to extend the non-usage period by 30 days at a time. Losing a number you've used for years, and every bank and UPI account linked to it, is far more trouble than a small recharge.
Frequently asked questions
How do I know my recharge was successful?
Your operator must send an SMS when the voucher is activated, stating the amount, validity and benefits. The app's success screen alone only confirms the payment.
Can I recharge someone else's number?
Yes. Enter their number and choose their operator and circle. Double-check the number, because a recharge sent to the wrong number generally can't be reversed once it's activated.
What happens if I choose the wrong operator?
The recharge usually fails, because the operator can't apply a plan to a number it doesn't serve. If you were charged, the amount should come back as a failed transaction or a refund.
Can I get a refund for a recharge to the wrong number?
There's no general rule requiring one. Contact the app and the operator immediately with the transaction details; if the recharge hasn't been processed, it may still be stopped.
Is there a minimum recharge to keep my number active?
TRAI's rules say a prepaid number can't be deactivated for non-usage for at least 90 days, and not at all while more than ₹20 sits in your account, though the operator may deduct up to ₹20 to extend the period. Operators' own plans and rules also apply, so check with yours.
