✅ Last verified on-the-ground: 2026-07-22
You landed at Tan Son Nhat or Noi Bai, slotted your shiny new Viettel or Mobifone tourist SIM into your phone, and now, three weeks into the trip, the dreaded “Your data will run out soon” notification has popped up. Do not panic. Recharging a Vietnam SIM as an Indian traveler is far simpler than it looks from the airport kiosk, and the whole process takes about five minutes once you know where to look. This guide covers every practical way to add credit to a Viettel, Mobifone, or Vinaphone tourist SIM in Vietnam, with the real prices, the apps that work, and the common mistakes that cost you data at the worst possible time.

The current exchange rate is roughly 1 INR = 270 VND right now, which is the number you need in your head whenever a shopkeeper quotes you a top-up price. A ₹184 (~50,000 VND or ~$1.91) top-up is about ₹185 (~$1.92), a ₹367 (~100,000 VND or ~$3.81) package is around ₹370 (~$3.84), and the big ₹734 (~200,000 VND or ~$7.62) monthly data bundles sit near ₹740 (~$7.68). None of these are huge numbers, so the trick is knowing which recharge to buy and where to buy it, not pinching the smallest dong.

Buy the Right SIM First, Recharge the Right Way Second
If you have not bought your SIM yet, your recharge decision is partly set by which carrier you walk out of the airport with. The three big tourist-SIM options at Tan Son Nhat, Noi Bai, and Da Nang are Viettel’s Tourist SIM, Mobifone’s Tourist SIM, and Vinaphone’s Tourist SIM. All three come pre-loaded with data, all three run on the same ₹477 (~130,000 VND or ~$4.96) price band for the standard 14-day tourist package, and all three accept the same general recharge methods. The differences show up in app quality and tourist-specific top-up bundles.
The canonical tourist SIM price for a 14-day Viettel or Mobifone package with around 6GB of data sits at ₹477 (~130,000 VND or ~$4.96). You will see the same number at airport counters, licensed SIM shops in District 1 of Ho Chi Minh City, and the official Viettel/Mobifone stores in Hanoi. Airport kiosks sometimes quote higher because of the convenience premium, so if you have time, walking to a carrier store or a hotel that helps with SIM registration is the cheaper path. Travellers report the easiest setups come from buying directly at the carrier’s own retail shop rather than resellers in tourist markets, where the SIM is the same but the seller pressure to add credit is higher.
If you already have your SIM and just need to add data or talk time, skip ahead to the recharge methods below. If you are still deciding, the Vietnam SIM card cost guide for Indian travelers breaks down which carrier wins for which kind of traveller.
The Four Recharge Methods That Work for Indians
There are four ways to recharge a Vietnam SIM as a foreign tourist: cash at a convenience store, scratch card, official carrier app or website, and help from your hotel or hostel. Each has trade-offs in cost, speed, and language barrier.
1. Cash at Circle K, FamilyMart, or 7-Eleven
This is the method most Indian backpackers end up using, because it is the most obvious and requires zero Vietnamese language skill. Walk into any Circle K, FamilyMart, or 7-Eleven, walk up to the counter, hold up your phone showing the screen with your phone number (the one printed on the SIM packaging or visible in your phone settings), and say the magic word: “nap dien thoai” if you want to top up your main balance, or “nap data” if you want a data package. The staff will pull up a recharge card, ask you which carrier (Viettel, Mobifone, Vinaphone) and how much, and ring it up. You hand over cash, they swipe the code, and your phone buzzes with a confirmation SMS within 30 seconds.
Top-up denominations at convenience stores usually start at 10,000 VND for a balance top-up (you then convert that balance into a data package via USSD code, see below) and go up in ₹73 (~20,000 VND or ~$0.76), ₹184 (~50,000 VND or ~$1.91), ₹367 (~100,000 VND or ~$3.81), ₹734 (~200,000 VND or ~$7.62), and ₹1,836 (~500,000 VND or ~$19.06) increments. For a 2-week trip, one 100,000 VND top-up midway through, converted into a 7-day data package, is enough for most backpackers who use WiFi at hostels.
The catch: clerks at non-touristy Circle K branches sometimes struggle with English. Holding your phone screen up and pointing at your carrier logo usually solves it. If you want a specific data package (more on this below), ask your hostel reception to write down the package name and price in Vietnamese before you go to the store.
2. Scratch Cards
Scratch cards are the old-school method and the one every Vietnamese shopkeeper defaults to if you just say “top up.” They are small cardboard cards with a hidden PIN under silver scratch-off. You buy a card for ₹184 (~50,000 VND or ~$1.91) or ₹367 (~100,000 VND or ~$3.81), scratch it, dial a USSD code on your phone, enter the PIN, and the credit lands in your account.
The downside for Indian travelers is that scratch cards do not always include a data package. Many are pure balance top-ups, which means you still have to register a data package separately through USSD codes, which means more Vietnamese-language menus. Travellers report that scratch cards are useful as a backup if you arrive in a small town with no convenient store or if your phone is locked to a specific carrier, but they are not the cleanest method. They are also slightly more expensive than buying the same value through a carrier app because the card has a packaging cost.
If you do end up with a scratch card, the universal USSD code for topping up across all three carriers is 100 followed by the PIN, then the call button. You will get an SMS confirming the credit.
3. Carrier Apps and Websites (The Best Method Once You Have a Card)
This is the single best way for Indian travelers to recharge a Vietnam SIM, and the option most tourists never use because nobody tells them it exists. All three major carriers have English-language apps and websites that accept international Visa and Mastercard cards.
Viettell’s recharge portal lives at viettel.vn and works through any browser. Mobifone runs recharge at mobifone.vn, and Vinaphone at vinaphone.com.vn. All three accept foreign cards, all three display prices in VND, and all three let you pick a specific data package rather than just dumping credit into your main balance. The exchange rate on your card statement will be whatever your bank charges for VND, which is usually within a percent of the market rate.
There is one important caveat: most international cards work fine for the recharge itself, but a few Indian-issued cards (especially some older debit cards) get rejected by Vietnamese payment gateways. If your card declines, the workaround is to top up at a convenience store, which is the whole reason the previous method exists.
If your phone is eSIM-capable and you would rather skip the physical SIM altogether, Get Nomad eSIM lets you buy data plans for Vietnam before you leave India and activate on landing. It is a good backup if you do not want to queue at the airport kiosk.
4. Help From Your Hostel or Hotel
Most hostels in the backpacker districts of Ho Chi Minh City, Hanoi, Da Nang, and Hoi An handle SIM top-ups for guests as a normal service. Front desks in Pham Ngu Lao, the Old Quarter, and An Thuong keep a stack of recharge cards and know which data package is best for a tourist who needs data for maps and Grab. The cost is the same as a convenience store, and the language barrier goes away.
This is the easiest path if you are tired after a bus ride, do not want to figure out Circle K at 11 PM, and trust your hostel’s recommendation. Travellers report that some hostels in District 1 and the Old Quarter will recharge a ₹367 (~100,000 VND or ~$3.81) package for a small tip of ₹37-₹73 (~10,000-20,000 VND or ~$0.38-$0.76) on top of the recharge value.
How to Pick the Right Data Package
Recharging your main balance is only step one. The bigger decision is which data package to register on top of that balance, because raw credit in your account does not buy data directly. You need to subscribe to a package, and the package determines how many GB you get, how long it lasts, and whether it includes 4G/5G speeds or throttles to 3G.
For Viettel tourist SIMs, the most popular data packages are:
- ST30K: ₹110 (~30,000 VND or ~$1.14) for 7 days, around 2GB to 4GB depending on current promo
- ST70K: ₹257 (~70,000 VND or ~$2.67) for 7 days, around 5GB
- ST150K: ₹551 (~150,000 VND or ~$5.72) for 30 days, around 12GB to 15GB
For Mobifone, the equivalent tourist-friendly packages are:
- MXH50: ₹184 (~50,000 VND or ~$1.91) for 7 days, around 3GB
- MXH100: ₹367 (~100,000 VND or ~$3.81) for 30 days, around 8GB
- M90: ₹330 (~90,000 VND or ~$3.43) for 30 days, around 5GB
For Vinaphone, the main tourist packages sit at similar price points, with MY and BIG data bundles running ₹184-₹734 (~50,000-200,000 VND or ~$1.91-$7.62).
Registering a package is done by dialing a USSD code, sending an SMS, or tapping through the carrier app. The exact codes change every few months as carriers run promotions, so the safest move is to either check the carrier’s app for the current menu or ask the convenience store clerk to register the package when you buy the recharge. Almost all Circle K staff will do this for free if you tell them the package code.
The Five-Step Recharge Flow for First-Timers
If this is your first time recharging a Vietnam SIM and you want the no-stress checklist, here is the exact sequence:
- Find your phone number. It is on the SIM packaging and in Settings → About Phone on your handset. Viettel numbers start with 09x or 03x, Mobifone with 09x, Vinaphone with 09x or 08x. Write it down or screenshot it.
- Pick a top-up amount. For a 2-week trip, ₹367 (~100,000 VND or ~$3.81) is the sweet spot. For a 1-month trip with heavy Google Maps and Grab usage, ₹734 (~200,000 VND or ~$7.62).
- Choose your method. Convenience store for cash-only travelers, app/website for card holders, hostel reception if you do not want to leave.
- Buy the recharge. Cash, scratch card, or card payment. Keep the receipt until the confirmation SMS arrives.
- Register a data package. Either through the carrier app or by USSD code. The data package is what gives you GB. Skipping this step leaves you with credit in your main balance but no internet.
Common Mistakes Indian Travelers Make With Vietnam SIM Recharges
The same handful of errors trip up most first-time visitors, and they all cost data or money.
Mistake 1: Recharging the main balance and assuming the data will flow. Raw balance does not buy data. You have to register a data package, which is a separate step. If you loaded ₹367 (~100,000 VND or ~$3.81) into your account and your data is still showing zero, dial the carrier’s data package USSD code (Viettel: *098# plus option for ST packages; Mobifone: *090# plus option for MXH; Vinaphone: *888#) and pick a package.
Mistake 2: Buying the cheapest ₹37 (~10,000 VND or ~$0.38) top-up and expecting it to last. A ₹37 (~10,000 VND or ~$0.38) recharge is fine for a few days of light use, but most backpackers burn through it in 24 hours if they are using Grab and Google Maps heavily. The mid-tier ₹184-₹367 (~50,000-100,000 VND or ~$1.91-$3.81) packages are the right answer for almost everyone.
Mistake 3: Paying double at the airport because you forgot your recharge plan. Airport SIM counters quote tourist packages at ₹477-₹734 (~130,000-200,000 VND or ~$4.96-$7.62). The same package in a city-center Viettel store is the lower end of that range. The premium is small but real, and it adds up if you also top up at the airport counter.
Mistake 4: Forgetting which carrier you are on. Sounds silly, but if you buy three scratch cards in three different small shops, the carrier name on your SIM card is what matters, not the brand on the shop sign. Screenshot the carrier logo from your settings screen before heading out.
Mistake 5: Using roaming or international top-up apps that mark up the price. Some Indian travel apps offer “international SIM top-up” services that charge 15 to 25 percent above the carrier’s own price. The carrier’s own website or a Circle K counter is always cheaper.
What Happens When Your SIM Expires
The 14-day tourist SIM has a 14-day validity from activation, not from purchase. After 14 days, the data stops working even if you still have credit in your account. To extend it, you can:
- Buy a fresh 14-day tourist SIM at any carrier store for the standard ₹477 (~130,000 VND or ~$4.96). This is the cleanest option and what most Indian backpackers do on month-long trips.
- Convert your tourist SIM to a longer-term plan at a carrier store. You will need your passport and 30 to 60 minutes of patience. This is more cost-efficient if you stay in Vietnam for 60+ days.

Safety, Scams, and What to Watch Out For
Recharging a SIM in Vietnam is generally safe, but the usual tourist hustle applies. The two specific scams worth knowing:
The “wrong carrier” recharge. A clerk sells you a Vinaphone recharge when your SIM is Viettel, and the credit disappears into thin air. Always confirm your carrier name before paying.
The “extra fee” convenience store trick. A clerk adds a ₹73-₹184 (~20,000-50,000 VND or ~$0.76-$1.91) “service fee” on top of the recharge value, which is not standard. The standard markup is zero at Circle K, FamilyMart, and 7-Eleven. If someone quotes you a fee, walk out and try the next store.

FAQ
How long does a Vietnam SIM recharge take to activate?
Cash recharges at convenience stores and scratch card top-ups activate within 30 seconds to 2 minutes. App and website top-ups are usually instant but can take up to 15 minutes during peak hours.
Can I recharge my Vietnam SIM with an Indian debit or credit card?
Yes, on Viettel, Mobifone, and Vinaphone websites and apps. Most Visa and Mastercard cards issued in India work. Some HDFC and older SBI debit cards get declined, in which case use a credit card or fall back to a convenience store cash top-up.
What is the cheapest way to recharge a Vietnam SIM?
Cash at a Circle K or FamilyMart for ₹37 (~10,000 VND or ~$0.38) and up is the cheapest per transaction. The cheapest per GB is buying a 30-day package directly through the carrier app, which costs around 8-12 VND per MB versus 25-50 VND per MB on small top-ups.
Can I recharge a Vietnam SIM online before arriving in Vietnam?
No. You need a Vietnamese phone number to register on the recharge portal, and the number is only issued when the SIM is activated in-country. The exception is eSIM services like Nomad, which let you buy a data plan before departure and activate on landing.
How do I know which carrier my SIM is?
Check Settings → About Phone → Network on your phone, or look at the SIM card itself (each carrier prints its name on the plastic). Viettel numbers start with 09x, Mobifone with 09x or 07x, Vinaphone with 09x or 08x.
Will my Vietnam SIM work in Cambodia, Thailand, and Laos?
Vietnam tourist SIMs do not include roaming by default. Some carriers sell regional add-ons for an extra ₹184-₹367 (~50,000-100,000 VND or ~$1.91-$3.81), but it is usually cheaper to buy a local SIM at each border than to add roaming. If you are crossing multiple borders, the how to top up your Vietnam SIM card in 2026 guide has a comparison.
What happens if I lose my Vietnam SIM?
Report the loss at any carrier store with your passport. The carrier will issue a replacement with the same number, usually for a ₹92-₹184 (~25,000-50,000 VND or ~$0.95-$1.91) fee. Any remaining credit transfers to the new SIM.
Subodh’s Take
Recharging a Vietnam SIM as an Indian traveler is the easiest technical task of the whole trip. The convenience store method works for everyone, the apps work for anyone with a foreign card, and the prices are so low that picking the wrong package costs you at most ₹184 (~50,000 VND or ~$1.91). The actual mistake most people make is overthinking it and ending up at the airport counter paying double for a package they could have bought at any Circle K for less. Buy the SIM at a real carrier shop on day one, screenshot your phone number and carrier name, and then treat recharge as a 5-minute errand rather than a research project. Done right, your phone keeps working for the entire trip for under ₹1,500 (~$15.57) in total spend.
