Best eSIM for Thailand from India vs Jio and Airtel Roaming Packs: GB per Rupee, OTPs and Calls (2026)

Last verified: 8 November 2026. Carrier prices were checked on jio.com, airtel.in and the carriers' official PDFs on that date. Our prices were read from the simswift store the same day.

Thailand is the first trip many Indian travellers take: Bangkok, Phuket, Pattaya, Krabi. You have three ways to stay online there. You can buy a Jio or Airtel international roaming pack, roam on pay-as-you-go rates, or install a Thailand data eSIM before you fly. This guide compares all three in rupees per GB, using only official Jio and Airtel sources.

Short answer: a Thailand eSIM costs far less per GB than any Airtel pack we could verify. 5 GB for 30 days is about ₹478. Airtel's closest pack is 4 GB for 5 days at ₹998. The packs still make sense if you need lots of normal calls on your Indian number. Keep your Indian SIM switched on either way, so bank OTPs reach you.

Our prices in rupees

Shoppers in India see our prices in rupees and pay in rupees at checkout. The rupee prices below are what our store charged in India on 8 November 2026, rounded to the nearest rupee. They follow the exchange rate, so they move a little from day to day. The US dollar price in brackets is what shoppers outside India pay.

Jio roaming in Thailand: what the official sources show

Jio's IR guide PDF lists East Asia Packs with "2 validity options". They apply only in Thailand, Singapore, Japan, Hong Kong, Macau, South Korea, Malaysia, Sri Lanka, Taiwan and Vietnam. The same guide says prepaid pack validity starts with your first roaming call, SMS or data use abroad.

We could not confirm current Jio Thailand pack prices. The jio.com Thailand roaming page loads its pack list inside the browser, and no prices were readable when we checked on 8 November 2026. News sites quote older launch prices, but we are not repeating them as current. Open MyJio and choose Thailand to see today's packs.

Jio's pay-as-you-go rate card (PDF dated January 2026) does list Thailand:

  • Data: ₹0.02 per 10 KB, about ₹2,000 per GB
  • Local calls and calls to India: ₹2 per minute
  • Calls to other countries: ₹100 per minute
  • Incoming calls: ₹2 per minute
  • Outgoing SMS: ₹2 each

Calls are cheap at these rates, but ₹2,000 per GB adds up quickly once maps and Instagram run in the background.

Airtel roaming in Thailand: what the official sources show

Airtel's international roaming terms PDF (September 2026) lists Thailand among its pack-covered countries. Its partner networks there are AIS, DTAC and AWN. The same PDF sets out the prepaid packs:

  • ₹698 for 1 day: 1 GB, 100 minutes, 10 SMS
  • ₹998 for 5 days: 4 GB, 150 minutes, 20 SMS
  • ₹1,298 for 10 days: 6 GB, 200 minutes, 20 SMS
  • ₹2,998 for 30 days: 10 GB, 300 minutes, 20 SMS

Minutes cover outgoing and incoming calls, local and to India. Incoming SMS is free on every pack. After the pack's minutes run out, calls cost ₹10 per minute and SMS ₹5. A 2 GB data top-up costs ₹699. Airtel's Thailand travel guide on airtel.in (updated 21 May 2026) shows the same four prices.

Two more Airtel options matter:

  • ₹118 roaming activation (prepaid): valid 28 days, with free incoming SMS. Calls, data and outgoing SMS are charged at standard rates. You also need an active Indian prepaid pack for it to work.
  • Free trip pack (new postpaid plans): from 8 October 2026, Airtel's new postpaid plans include one free trip a year. It gives 5 GB, 60 minutes and 25 SMS for 5 days. The press release does not list countries, so confirm Thailand in Airtel Thanks.

Avoid Airtel's standard rates for data. Its standard-charges PDF (dated 2023) lists Thailand data at ₹6.50 per 10 KB, which is several lakh rupees per GB. Postpaid users get a daily cap: once charges pass ₹698 in a day, Airtel switches on its ₹698 day pack automatically.

Our plans are data only, with no Indian or Thai phone number. Airtel's packs bundle minutes and SMS on your own number, so per GB alone flatters the eSIM a little. Even so, the gap in Thailand is wide: 10 GB costs about ₹766 with us against ₹2,998 on Airtel.

How much data you need in Thailand

  • 4 to 5 day Bangkok or Pattaya trip: 2 GB covers Grab, Google Maps and WhatsApp, with hotel Wi-Fi for the rest.
  • One week, Bangkok plus Phuket or Krabi: 3 GB to 5 GB, enough for daily reels, island ferries and hotel bookings on the go.
  • Two weeks, or a family sharing one phone's hotspot: 10 GB.
  • Work trip, video calls or a long stay: 20 GB for 30 days. For six months there is 50 GB valid 180 days at about ₹4,793 ($49.99).

If you would rather not count GB, our Thailand daily plan gives 1 GB a day for about ₹191 a day ($1.99 outside India). After the day's 1 GB, speed drops to 1 Mbps until the next day.

The Thailand eSIM runs on TrueMove H and DTAC, with 5G where available. Hotspot works on most plans, so one phone can cover a parent or partner. Fixed plans can be topped up if you run low.

Pick your Thailand eSIM size: 1 GB, 2 GB, 3 GB, 5 GB, 10 GB or 20 GB, with prices shown in rupees for shoppers in India.

Keep your Indian SIM active for bank and UPI OTPs

Your bank sends OTPs by SMS to your Indian number. If that SIM is off or not registered abroad, you can't approve card payments or log in to net banking from Thailand. The fix is dual SIM: keep your Jio or Airtel physical SIM in the phone and add the eSIM as a second line.

  1. Install the eSIM in India over Wi-Fi. It starts its validity only when it connects to a network in Thailand. You have 180 days from purchase to activate it.
  2. On landing at Suvarnabhumi or Don Mueang, set the eSIM as your mobile data line and turn on data roaming for that line.
  3. Leave the Indian SIM on for calls and SMS, but turn off data roaming on it.
  4. Before you fly, make sure international roaming works on your number. Airtel prepaid users can use the ₹118 activation for free incoming SMS. Jio users should check in MyJio what their connection needs.

WhatsApp stays on your Indian number and works over the eSIM's data, so your chats and groups carry on as normal.

Incoming calls and SMS while roaming

Receiving calls abroad is not free. Jio's pay-as-you-go card charges ₹2 per minute for incoming calls in Thailand. Airtel counts incoming calls against the pack's minutes, then charges ₹10 per minute. Without any Airtel pack, its 2023 standard card lists incoming calls at ₹100 per minute.

Incoming SMS is free on Airtel packs and on the ₹118 activation. To save money, let unknown numbers go to voicemail and ask family to call on WhatsApp instead.

Which phones sold in India support eSIM

Airtel's eSIM page has setup steps for Apple, Google Pixel, Samsung, Motorola, Vivo, OPPO and OnePlus. Support still depends on the exact model:

  • iPhone: XR, XS and every later model.
  • Samsung: recent Galaxy S and Z Fold or Z Flip models. Many Galaxy A and M phones sold in India have no eSIM.
  • Pixel, Motorola, Vivo, OPPO and OnePlus: only some models, so check yours.

The quickest check is to dial *#06#. If an EID number appears, your phone supports eSIM.

Paying from India

Shoppers in India pay in rupees, by card, Apple Pay or Google Pay. We do not accept UPI. We are a UK company, so some banks may still add an international transaction fee, even though you pay in rupees. Check your card's terms. Many Indian cards ship with international online payments switched off, so turn them on in your banking app first.

When a Jio or Airtel pack is the better choice

  • You have a new Airtel postpaid plan and the free 5-day trip pack covers Thailand. Free beats any eSIM.
  • You make a lot of normal calls on your Indian number, for work or family. 150 to 300 bundled minutes have real value.
  • Your phone has no eSIM. A roaming pack is then the simplest option.
  • You want one rupee bill and no foreign card payment at all.

For most data use, the eSIM wins in Thailand, from short Bangkok breaks to month-long stays. Visiting Malaysia or Singapore on the same trip? See the Malaysia, Singapore and Thailand eSIM or our Asia eSIM guide. Flying to Dubai next? Read our Dubai eSIM from India comparison.

Can I pay for the eSIM with UPI?

No. Shoppers in India pay in rupees, by card, Apple Pay or Google Pay. Some banks may add an international transaction fee because we are a UK company, and you may first need to enable international online payments on your card.
