Three networks, very cheap data, and good coverage everywhere except the mountains.
- ๐ฆ๐ฟ eSIM and SIM cards in Azerbaijan
Three networks, decent coverage, and a registration rule that also applies to phones.
- ๐ง๐ญ eSIM and SIM cards in Bahrain
Three networks on an island 50 km long. Coverage is not a problem here.
- ๐ง๐ฉ eSIM and SIM cards in Bangladesh
There is a proper tourist SIM, free, on a passport and visa, and a SIM shop just past customs at Dhaka.
- ๐ฐ๐ญ eSIM and SIM cards in Cambodia
Cambodia has some of the cheapest mobile data anywhere: USD 5 buys 30 GB, and USD 10 buys up to 100 GB. This is one of the few countries where buying at the airport is not a mistake.
- ๐จ๐ณ eSIM and SIM cards in China
The Great Firewall blocks Google, WhatsApp and Instagram on any local SIM or Wi-Fi. An international eSIM such as Saily roams through servers outside mainland China, so those apps work with no VPN - but it has to be installed before you fly, because foreign eSIM profiles cannot be downloaded once you land.
- ๐ฌ๐ช eSIM and SIM cards in Georgia
MagtiCom is the one to buy if you are going into the mountains - it is the only network with reliable signal in Kazbegi and Svaneti, and it works in the Tbilisi metro. Kiosks in the arrivals halls at Tbilisi and Kutaisi sell tourist SIMs.
- ๐ญ๐ฐ eSIM and SIM cards in Hong Kong
A tourist SIM is cheap and sold in every 7-Eleven, and Hong Kong has some of the densest free public wi-fi anywhere. An eSIM saves the errand.
- ๐ฎ๐ณ eSIM and SIM cards in India
An eSIM bought before departure gets you online the moment you land with no paperwork - but gives you no Indian number, and Uber and Ola need one for the OTP. A local SIM is a fraction of the price and needs your passport, visa, an Indian address and a photo taken at the counter, then hours to activate.
- ๐ฎ๐ฉ eSIM and SIM cards in Indonesia
A local SIM is dramatically cheaper here than an international eSIM - XL's tourist eSIM is 30 GB for 70,000 IDR against Saily's 3 GB for USD 8.99 - and both are bought online before you land. Telkomsel has the widest coverage outside the tourist strips. Any local SIM needs your passport.
- ๐ฏ๐ต eSIM and SIM cards in Japan
A data eSIM bought before departure is the default: no passport registration, and it works the moment you land. Saily is 10.99 USD for 5 GB or 17.99 USD for 10 GB over 30 days. Only voice SIMs are legally required to be registered against a passport in Japan - data-only cards are not.
- ๐ฏ๐ด eSIM and SIM cards in Jordan
Zain and Umniah have counters in the arrivals hall and want your passport. About JOD 15 buys a tourist bundle with more data than a fortnight needs; coverage in Wadi Rum is patchier than the brochures suggest.
- ๐ฐ๐ฟ eSIM and SIM cards in Kazakhstan
A local SIM means passport registration in person at the counter and noticeably inflated tourist pricing. A Saily eSIM bought before departure runs on the Beeline network, which has the widest 4G and 5G coverage in the country.
- ๐ฐ๐ผ eSIM and SIM cards in Kuwait
Three networks, fast data, and total coverage across a small and heavily urban country.
- ๐ฐ๐ฌ eSIM and SIM cards in Kyrgyzstan
Cheap, fast data in the valleys and nothing at all in the mountains, which is where you will be.
- ๐ฑ๐ฆ eSIM and SIM cards in Laos
Unitel and Lao Telecom have the densest networks and passport registration is mandatory for both. About USD 4.75 buys Unitel's 35 GB tourist package, which keeps working along the Laos-China railway where the others drop out.
- ๐ฒ๐ด eSIM and SIM cards in Macao
Macao is small enough that free public wi-fi almost covers it, and a Hong Kong tourist SIM often includes Macao data.
- ๐ฒ๐พ eSIM and SIM cards in Malaysia
Every SIM and eSIM sold in Malaysia needs passport registration at the counter. CelcomDigi's tourist passes run RM 15 for 3 days to RM 60 for 30, all unlimited but capped at 18 Mbps, with a RM 60 alternative giving 200 GB at full speed and a RM 5 activation fee on top. Every pass includes roaming in ten ASEAN countries, so a multi-country trip needs no second SIM.
- ๐ฒ๐ป eSIM and SIM cards in Maldives
Dhiraagu and Ooredoo both sell tourist SIMs in the Velana arrivals hall, with passport registration in person: Ooredoo's USD 40 pack is 20 GB over 10 days, and USD 50 buys 30 GB plus 70 GB of social data. Dhiraagu has the better coverage on the outer atolls. Roaming is prohibitively expensive.
- ๐ณ๐ต eSIM and SIM cards in Nepal
A local SIM costs about NPR 500 with a passport and a photo, and Ncell reaches further up the trekking trails than anything else. An eSIM is the expensive option here, not the cheap one.
- ๐ด๐ฒ eSIM and SIM cards in Oman
Two networks, good coverage on the roads that matter, and nothing in the mountains or the Empty Quarter.
- ๐ต๐ฐ eSIM and SIM cards in Pakistan
The SIM is the easy part. Pakistan blocks handsets by IMEI, and a visitor gets 120 days for exactly one device, paired to one number.
- ๐ต๐ญ eSIM and SIM cards in Philippines
Comparison of connectivity options for the Philippines: Globe and Smart tourist eSIMs (โฑ1,750 / โฑ1,599, 30 days), โฑ99 local eSIM starters, DITO, an international Saily eSIM, and home-operator roaming. Includes recommendations by trip length and budget; Globe and Smart offer the best airport availability, and all local SIMs require passport registration.

Two networks, kiosks in the arrivals hall, and a passport required. Coverage is total, prices are not low, and WhatsApp calling works here unlike its neighbour.
- ๐ธ๐ฆ eSIM and SIM cards in Saudi Arabia
Excellent networks, cheap data, and a registration process that is strict about matching your visa.
- ๐ธ๐ฌ eSIM and SIM cards in Singapore
Cheap, fast and completely painless. Buy at Changi or activate an eSIM before you land, and the coverage question does not arise on an island this size.
- ๐ฐ๐ท eSIM and SIM cards in South Korea
Data matters more here than in most countries: Google Maps has no reliable walking directions in Korea because map data cannot be exported, so you need Naver Map or KakaoMap - and both need a live connection. An eSIM bought before departure has you online in the immigration queue.
- ๐ฑ๐ฐ eSIM and SIM cards in Sri Lanka
A Saily eSIM activated before departure avoids airport queues, passport handling and Sri Lanka's IMEI-blocking rule for unregistered phones. Physical tourist SIMs from Dialog, SLT-Mobitel and Hutch cost 821โ1,799 LKR for 15โ30 GB at the 24/7 CMB airport kiosks, with passport registration and a photo taken on the spot.
- ๐น๐ผ eSIM and SIM cards in Taiwan
Chunghwa Telecom's 10-day unlimited 5G tourist pass is the top pick - 580 NTD when pre-ordered via Klook/KKday (vs 800 NTD walk-up at the airport). Registration legally requires a passport plus a second ID at 18+. Counter locations and hours for Taoyuan, Songshan and Kaohsiung airports included.

- ๐น๐ท eSIM and SIM cards in Turkey
Turkey registers the phone, not just the SIM. Use a Turkish SIM and your handset is blocked after 120 days unless you pay a fee of over 54,000 lira.
- ๐ฆ๐ช eSIM and SIM cards in United Arab Emirates
Two networks, free tourist SIMs at the airport, and VoIP calling that is still restricted, so WhatsApp voice and FaceTime may not work.
- ๐บ๐ฟ eSIM and SIM cards in Uzbekistan
All four networks have desks in the Tashkent arrivals hall. Take Ucell or Uzmobile, insist the passport registration is actually done, and expect data to thin out between cities.
- ๐ป๐ณ eSIM and SIM cards in Vietnam
Compares Viettel, the MobiFone Travel eSIM, airport tourist SIMs, the international Saily eSIM and roaming for Vietnam. Viettel from an official store offers the best coverage and value (e.g. 60,000 VND 7-day plans), while an eSIM activated before departure is the easiest option for short trips and the first minutes after landing.
