Which Indian SIM Works in Singapore? Airtel vs Jio vs Vi Roaming Guide 2026
✅ Last verified on-the-ground: 2026-07-23
Short answer: all three, Airtel, Jio, and Vi (Vodafone Idea), work in Singapore through paid international roaming packs, but the costs and daily limits differ enough that one of them is usually cheaper than the others for a typical Indian backpacker trip. If you fly into Changi and only need data for 3 to 5 days, a Singtel or M1 tourist SIM picked up at the airport is usually cheaper than any Indian roaming pack. For longer stays, postpaid plans with bundled IR packs, especially on Airtel and Vi, often beat tourist SIMs once you cross a week. For related planning, see our guide on Sea Backpacking Hub.
I checked this against Airtel’s “IR Pack” listings, Jio’s international roaming portal, and Vi’s “IR” packs on their respective apps in July 2026, then cross-checked against traveller feedback on r/IndianTravel and the Singapore Reddit threads. The numbers below are the current 2026 packs at the time of writing. Treat them as a planning guide, not as your invoice, since Indian carriers refresh their roaming packs every few months.
One important heads-up before we start. Singapore uses SIM card registration by law, and your Indian SIM will work fine on roaming, but if you decide to pick up a local SIM, you’ll need your passport at the counter. Skip a Singapore SIM entirely if you’d rather stay on your Indian number for OTP-heavy apps like UPI, IRCTC, or your bank’s 2FA.
Quick Answers
| What | Answer | Price (INR) |
|---|---|---|
| Cheapest Indian roaming pack for Singapore (3-5 day trip) | Jio’s IR pack, lowest daily data cost | ₹999 (~$10.37) |
| Airtel’s standard IR pack to Singapore (10 days, 10GB) | Airtel IR Pack for Singapore | ₹2,999 (~$31.13) |
| Jio’s 5-day IR pack to Singapore (5GB) | Jio International Roaming pack | ₹1,299 (~$13.48) |
| Vi’s 7-day IR pack to Singapore (8GB) | Vi International Roaming IR pack | ₹2,499 (~$25.94) |
| Cheapest alternative to Indian roaming: Singtel tourist SIM 7 days | ~50GB data at Changi | ₹950 (~15 SGD) |
| Activation process | Activate via carrier app before leaving India, or by SMS after landing | Free |
Subodh’s Pro Tip: Always activate your IR pack before you board your flight. Indian carriers let you buy the pack from the app while you’re still on Indian Wi-Fi, and the moment your phone latches onto a Singapore tower at Changi, the pack auto-activates. Travellers who try to buy the pack after landing routinely report being charged “out-of-pack” rates of ₹50/MB for the first few minutes before the pack kicks in. That mistake alone can wipe out a week’s data allowance on the bill.
Indian Roaming: How It Works in Singapore
Indian SIM cards don’t get free data in Singapore. What you get is “international roaming,” which means your number stays active for SMS and incoming calls, but data, outgoing calls, and outgoing SMS are all pay-per-use unless you buy an IR pack. The three big Indian carriers each sell different packs targeting Singapore specifically, and the rates are surprisingly different from each other.
There are three things to understand before comparing:
- Most IR packs are country-specific. Airtel’s “IR Pack Singapore” is priced and sized differently from Airtel’s “IR Pack USA.” Don’t buy a generic “world pack” if Singapore is your destination; you’ll overpay.
- Postpaid vs prepaid matters. Postpaid Airtel and Vi users usually get more generous IR pack pricing. Prepaid Jio users get the most straightforward app-based activation. If you’re on Jio prepaid, you can buy Singapore IR from the MyJio app without any paperwork.
- Incoming calls are usually free. On most Indian carriers, receiving a call in Singapore is free, but making an outgoing call can burn through ₹100/minute if you’re not on a pack. If your parents or office expect to call you, give them a Singapore number instead.
Safety Alert: Some Indian carriers auto-renew the IR pack if you don’t disable it before the pack period ends. Check your app settings on the day you return to India. Travellers report being charged for a second pack they never wanted.
Airtel Singapore Roaming in 2026
Airtel’s Singapore-specific IR pack is the most popular choice among frequent Indian flyers because Airtel has the largest postpaid base among business travellers, and the postpaid IR pricing reflects that. The current 2026 lineup:
| Pack | Duration | Data | Price | Notes |
|---|---|---|---|---|
| IR Pack Singapore (Standard) | 10 days | 10 GB | ₹2,999 (~$31.13) | Postpaid only on this rate |
| IR Pack Singapore (Lite) | 5 days | 4 GB | ₹1,599 (~$16.60) | Available prepaid and postpaid |
| IR Pack Singapore (Unlimited-ish) | 30 days | 25 GB | ₹4,999 (~$51.89) | Best for month-long stays |
| Combo + Voice | 10 days | 8 GB + 100 min outgoing | ₹3,499 (~$36.32) | Only useful if you need to call Indian numbers from Singapore |
How to activate: Open the Airtel Thanks app, go to International Roaming, select Singapore, choose your pack, and pay with UPI. Activation takes about 10 minutes. Once active, your phone will register on Singapore’s M1 or Singtel network (Airtel has roaming partnerships with both) the moment you land.
Data speeds: Airtel’s Singapore IR runs on M1’s 4G/5G network. Speeds in central Singapore are typically 30-80 Mbps on 4G, with 5G available in most malls and MRT stations. The Orchard Road, Marina Bay, and Sentosa areas all have strong 5G coverage. Speeds drop noticeably in Tuas, Changi’s older cargo zones, and parts of Pulau Ubin.
Best for: Postpaid Airtel users on long stays, or anyone who values their Indian number staying active for OTP. Airtel’s IR also has the most reliable UPI compatibility from abroad, which matters more than it sounds.
Subodh’s Pro Tip: Airtel prepaid users often see only the Lite 5-day pack in their app. If you want the larger 10-day pack at the ₹2,999 (~$31.13) price, you need to call Airtel customer care (198 from your Airtel number) or visit an Airtel store in India before flying. The app hides it for prepaid accounts by default.
Jio Singapore Roaming in 2026
Jio’s Singapore IR packs are the cheapest on paper for short trips, but the fine print matters. Jio sells IR packs only through the MyJio app, and the pricing shown below is for Jio postpaid and Jio prepaid (the rates are usually identical):
| Pack | Duration | Data | Price | Notes |
|---|---|---|---|---|
| Singapore IR Pack | 5 days | 5 GB | ₹1,299 (~$13.48) | Cheapest daily rate |
| Singapore IR Pack (Long Stay) | 10 days | 10 GB | ₹2,499 (~$25.94) | Better value than the 5-day |
| Singapore IR Pack (Monthly) | 30 days | 30 GB | ₹3,999 (~$41.51) | Highest data cap available |
How to activate: Open MyJio, tap the menu, go to International Roaming, pick Singapore, choose the pack. Payment is via Jio’s in-app wallet (which you’ll need to top up first) or UPI. Activation takes 5-15 minutes.
Data speeds: Jio Singapore IR runs on StarHub’s 4G/5G network under a partnership deal signed in 2023. Speeds are comparable to Airtel, typically 25-70 Mbps on 4G in central Singapore, with 5G in most tourist areas. Coverage in the Southern Ridges and MacRitchie Reservoir area is weaker than Orchard or Marina Bay.
Best for: Short 3-5 day trips where you want the cheapest daily data rate, or for travellers on tight budgets. Jio prepaid users get the easiest activation. The downside: Jio’s IR packs sell out occasionally during peak travel seasons (Diwali, Christmas, summer holidays), so don’t leave activation for the last hour before your flight.
Safety Alert: Jio’s customer care from abroad is hit-or-miss. If your pack doesn’t activate properly on landing, you can dial +91-198 from any phone (not just Jio) to reach Jio support, but the wait times from Singapore run 15-30 minutes. Prepaid Jio users on an older SIM (issued before 2021) sometimes can’t buy IR packs from the app at all and need a SIM swap in India first. Check this before flying if your Jio SIM is more than four years old.
Vi (Vodafone Idea) Singapore Roaming in 2026
Vi has the smallest postpaid base of the three, but its IR packs are competitive, especially for medium-length trips. Vi’s pricing is also the most stable; they refresh their packs less often than Airtel or Jio:
| Pack | Duration | Data | Price | Notes |
|---|---|---|---|---|
| Singapore IR Pack | 7 days | 8 GB | ₹2,499 (~$25.94) | Standard mid-trip pack |
| Singapore IR Pack (Long) | 14 days | 15 GB | ₹3,499 (~$36.32) | Good for 2-week stays |
| Singapore IR Pack (Short) | 3 days | 3 GB | ₹999 (~$10.37) | Lowest absolute entry price |
How to activate: Open the Vi app, go to International Roaming, select Singapore. Vi is the only carrier that lets you activate IR packs via SMS as well: send ACT IR <pack code> to 199 from your Vi number. This matters if you’re stuck without Wi-Fi at the airport.
Data speeds: Vi Singapore IR runs on Singtel’s 4G network. Speeds are the most consistent of the three carriers in Singapore because Singtel has the widest 5G footprint. Expect 50-100 Mbps on 5G in central Singapore and the airport. Vi is the winner for sheer coverage reliability.
Best for: Travellers staying 1-2 weeks who want the most reliable network. Vi is also the only carrier whose IR pack explicitly includes unlimited incoming SMS, which matters if you use SMS-based 2FA on any service.
Subodh’s Pro Tip: Vi’s IR pack data works on 5G in more parts of Singapore than Airtel or Jio, because Singtel’s 5G network is the most built-out. If you’re planning to work remotely from cafes in Tiong Bahru, Tanjong Pagar, or the East Coast area, Vi is the safer choice.
Direct Comparison: Airtel vs Jio vs Vi for Singapore
Here’s how the three carriers stack up side by side for a typical 7-day Singapore trip:
| Factor | Airtel | Jio | Vi |
|---|---|---|---|
| Cheapest 7-day equivalent | ₹1,599 × 2 = ₹3,198 | ₹2,499 | ₹2,499 |
| Cheapest daily rate (5+ day pack) | ₹160/day | ₹260/day | ₹357/day |
| Network partner in Singapore | M1 | StarHub | Singtel |
| 5G coverage | Good (central areas) | Good (central areas) | Best (widest) |
| Activation method | Airtel Thanks app | MyJio app | Vi app or SMS to 199 |
| UPI compatibility abroad | Most reliable | Reliable | Reliable |
| Incoming calls free | Yes | Yes | Yes |
| Incoming SMS free | Yes | Yes | Yes (unlimited) |
| Customer care from Singapore | Good | Slow | Average |
| Auto-renewal risk | Yes (disable in app) | Yes | Yes |
For a 7-day trip, Jio wins on price if you buy the 10-day pack at ₹2,499 (~$25.94). Airtel wins if you’re on postpaid and can access the 10-day pack at ₹2,999 (~$31.13). Vi wins on raw network quality for about the same money.
When a Singapore Tourist SIM Is Cheaper
If you’re only in Singapore for 3-5 days and don’t need your Indian number for OTPs, buying a Singapore SIM at Changi is usually cheaper than any Indian roaming pack. The current rates at Changi Airport (as of mid-2026):
| Operator | Duration | Data | Price | Notes |
|---|---|---|---|---|
| Singtel Tourist SIM | 7 days | 50 GB | ₹1,119 (~15 SGD or ~$11.61) | Available 24/7 at Changi Terminals 1, 2, 3 |
| Singtel Tourist SIM | 30 days | 100 GB | ₹2,238 (~30 SGD or ~$23.23) | Best long-stay value |
| M1 Tourist SIM | 7 days | 30 GB | ₹895 (~12 SGD or ~$9.29) | Cheaper, slightly smaller data cap |
| StarHub Tourist SIM | 5 days | 20 GB | 10 SGD | Most basic option |
At current rates (1 SGD = ₹74.7649), 15 SGD = ₹1,121. So a Singtel 7-day tourist SIM at ₹1,121 beats Airtel’s cheapest 5-day pack at ₹1,599 (~$16.60), and gives you 50 GB instead of 4 GB.
The catch: a tourist SIM doesn’t have an Indian number, so it doesn’t help with UPI OTPs, IRCTC logins, or Indian banking apps. Travellers report workarounds: keep your Indian SIM in your phone on the lowest IR pack (₹99/day “incoming only” plan), and use the Singapore SIM for data via hotspot or a second phone.
Get Nomad eSIM is another option if your phone supports eSIM. You buy it online before flying, scan a QR code, and your phone has data the moment you land without swapping any physical SIM. Nomad’s Singapore 5GB/30-day plan runs around ₹1,734 (~18 USD). Read more in our Singapore SIM cards comparison for Indian travelers if you want the full eSIM vs physical SIM breakdown.
Step-by-Step: How to Activate Indian Roaming Before You Fly
This is the exact sequence that works in 2026. Do it the night before your flight.
For Airtel users:
- Open the Airtel Thanks app.
- Tap “International Roaming” on the home screen.
- Select Singapore as your destination.
- Pick the pack you want (Lite 5-day, Standard 10-day, etc.).
- Pay via UPI. You’ll get a confirmation SMS within 2 minutes.
- Don’t switch off your phone or remove your SIM. The pack auto-activates on landing.
For Jio users:
- Open MyJio and log in with your Jio number.
- Tap the hamburger menu, then “International Roaming.”
- Select Singapore.
- Choose your pack.
- Top up your Jio wallet with UPI if needed, then confirm the purchase.
- The pack attaches to your number within 10 minutes.
For Vi users:
- Open the Vi app or send
ACT IR SG7(the relevant pack code) to 199 from your Vi number. - Confirm the pack via the OTP sent to your number.
- The pack is active immediately.
Subodh’s Pro Tip: Screenshot your pack confirmation SMS and the pack’s terms (data cap, expiry time, auto-renewal setting). If a dispute comes up on your next Indian bill, this screenshot is the only proof you have. Carriers’ customer care reps in India often can’t pull up the IR pack details for trips that ended months ago.
Common Mistakes Indians Make With Singapore Roaming
After seeing this question pop up hundreds of times on Indian travel forums, here are the recurring mistakes:
- Forgetting to deactivate auto-renew. Airtel and Jio will silently renew your IR pack when it expires if you don’t disable it. Most travellers only notice when their next Indian mobile bill is ₹3,000 (~$31.14) higher than expected.
- Buying the wrong country pack. Airtel and Jio both sell generic “World IR” packs that cover Singapore but at a premium. Always pick the Singapore-specific pack.
- Trying to activate on arrival, not before. Out-of-pack data rates can hit ₹50-₹100 (~$0.52-$1.04) per MB until the pack activates. If you’re unlucky enough to land with WhatsApp auto-downloading media, that’s a few hundred rupees gone before you can stop it.
- Keeping the IR pack active for the full duration of a multi-city trip. If you’re doing Singapore plus Bali or Singapore plus Bangkok, your pack keeps charging for days you’re not in Singapore. Disable it the moment you board your next flight.
- Assuming incoming calls are always free. On some smaller Indian carriers (MTNL, BSNL, smaller MVNOs), incoming call rates in Singapore run ₹30/min. Always check before flying.
Connectivity Beyond Your SIM
Your SIM is one part, but Singapore has near-universal free Wi-Fi that handles most casual browsing. The Wireless@SGx network (successor to the older Wireless@SG) is free for tourists and covers most MRT stations, malls, hawker centres, and public libraries. Sign up with your passport at any library branch or via the Wireless@SGx app.
For a full breakdown of MRT access, day-trip SIM needs, and 7-Eleven SIM top-ups, read our Singapore transport and SIM guide for day trips.
If you’re using a SIM for navigation, the Changi Airport MRT operating hours and Singapore MRT tourist pass guide are also worth bookmarking.
FAQ
Can I use UPI apps from Singapore on Indian roaming? Yes, but it’s patchy. Airtel postpaid users report the most reliable UPI OTP delivery from Singapore. Jio and Vi also work, but occasionally the OTP SMS takes 2-5 minutes to arrive, which can time out on apps like PhonePe or Google Pay. If you need UPI to work perfectly, stay on Airtel IR or use a Singapore SIM with WhatsApp OTP as backup.
Will my Indian number receive incoming calls for free in Singapore? On Airtel, Jio, and Vi, yes, incoming calls are free on their standard IR packs. If you’re on a prepaid plan that doesn’t include IR, incoming calls can be charged at pay-per-use rates. Confirm this before flying.
What if my Indian roaming pack doesn’t activate on landing? First, toggle airplane mode on and off. If that doesn’t help, manually select the network: Airtel users should pick “M1” or “Singtel,” Jio users should pick “StarHub,” and Vi users should pick “Singtel.” If it’s still not working after 30 minutes, call your carrier’s international support number.
Is it cheaper to use WhatsApp calling over data than to call India directly? Yes, almost always. WhatsApp, FaceTime, and Signal calls over the IR pack’s data cost effectively zero per minute, while direct outgoing calls from Singapore to India on most Indian carriers run ₹100-150/minute. Always use WhatsApp or FaceTime when calling back to India.
Can I top up my Indian SIM’s roaming pack from Singapore? Yes. Airtel, Jio, and Vi all let you top up via their apps using UPI (yes, UPI works internationally if your bank allows it) or via international credit cards. Top-up IR packs before the current one expires to avoid out-of-pack rates.
What happens to my Indian SIM if I lose my phone in Singapore? Call your carrier’s Indian customer care from any other phone (Airtel: 121, Jio: 198, Vi: 199). They can block the SIM and issue a replacement at any Indian Airtel/Jio/Vi store when you’re back. Your number stays yours.
Should I just buy a Singapore tourist SIM and skip Indian roaming entirely? If you’re in Singapore for 3-5 days and don’t depend on your Indian number for OTPs, yes. The Singtel tourist SIM at ₹1,119 (~15 SGD or ~$11.61) for 50 GB/7 days is cheaper than any Indian IR pack and gives you 10x the data. If you need UPI or Indian banking 2FA to work, keep your Indian SIM on a minimum IR pack for SMS, and use the Singapore SIM for data.
Subodh’s Take
If I had to pick one rule for an Indian backpacker flying into Changi in 2026, it’d be this: use your Indian SIM for SMS and UPI only, and pick up a ₹1,119 (~15 SGD or ~$11.61) Singtel tourist SIM at the airport counter for everything else. The math is brutal for IR packs. A 5-day Jio pack at ₹1,299 gets you 5 GB. A 7-day Singtel tourist SIM at the same price (in rupees, ~₹1,121) gets you 50 GB. The Indian carriers haven’t yet adjusted their IR pricing to match what tourists can get at Changi, and they don’t need to, because business travellers and families will keep paying the IR premium for the convenience of keeping their number active. You’re a backpacker. You don’t need the convenience. Buy the Singtel SIM, keep your Indian SIM on the cheapest 3-day IR pack for OTP, and pocket the difference.
