# eSIM for Bangkok For Bangkok, a Thailand eSIM covers the city and every day trip inside the country. Most visits last about four days, so choose a plan valid for at least that long, with a day or two to spare. Install it at home on Wi-Fi before you fly, then switch it on when you land at Suvarnabhumi or Don Mueang. Plans for Thailand cover the whole country, including Bangkok. > Checkout isn't open yet.

Suvarnabhumi (BKK) is the main international one, east of the centre, and the Airport Rail Link runs from its basement station to Phaya Thai, where you can change to the BTS Skytrain. Don Mueang (DMK) is north of the city and handles many regional and low-cost flights; taxis, airport buses and a rail connection to the main long-distance station run from there. That station is Krung Thep Aphiwat Central Terminal at Bang Sue, which replaced Hualamphong for most intercity trains. Having data when you step off the plane makes the first hour simpler: you can open a map, confirm your hotel address, check which exit the taxi queue uses and message whoever is meeting you. Install the eSIM at home on Wi-Fi by scanning the QR code, and leave it switched off until you land. At the airport, turn the eSIM line on and turn on data roaming for that line. Keep your home line's mobile data off so it does not run up charges. ## Getting around Bangkok's rail network is made of several systems that connect at a handful of stations: the BTS Skytrain over the main roads, the MRT underground lines, and the Airport Rail Link. Each has its own ticket machines, and the BTS and MRT use separate stored-value cards, so ask at the counter what you can use at the gate before you queue. The Chao Phraya Express Boat is the river commuter service, with stops at Sathorn Pier, Tha Tien for Wat Pho and other piers along the old city. For rides on the road, Grab operates in Bangkok and shows the fare before you confirm, and metered taxis are everywhere. Traffic can be heavy, so many visitors combine a train with a short ride at either end. Hotel and tour confirmations, rail maps and translation apps all want a live connection, and an offline map of the city is a useful backup for the walk from a station to a temple gate. ## Where you'll use data Most visitors split their time between the old city (the Grand Palace, Wat Pho, Wat Arun across the river), Chinatown at Yaowarat, and the shopping and dining districts around Siam, Sukhumvit and Silom. Chatuchak Weekend Market, Lumphini Park and the canal boat rides in Thonburi are common additions. Temples and palaces have dress rules and ticket queues, so many people check opening times and book guided tours on their phone the same morning. Day trips from Bangkok stay in Thailand more often than not: Ayutthaya by train, the floating markets west of the city, Kanchanaburi and the bridge over the River Kwai, or Pattaya and the Gulf coast by bus. All of these sit inside the country, so the Thailand plan keeps working. Overland trips to Cambodia, Laos or Malaysia are different: the Thailand plan does not cover those countries, and the other country has its own plan. ## Common questions ### Will the eSIM work as soon as I land at Suvarnabhumi? Yes, if you installed it before the flight. Switch the eSIM line on, turn on data roaming for it, and wait a minute for it to connect. If nothing happens, toggle airplane mode on and off once. ### How much data do I need for four days in Bangkok? About 2.5 GB for normal use: maps, a ride app, messages and some social media. Video calls home or heavy streaming take it to roughly 6 GB. The plan list on this page shows the estimate next to each plan. ### Can I pay for the BTS or MRT with my phone? Rules differ between the BTS, the MRT and the Airport Rail Link, and they change. Check the ticket office or the operator's official site before you travel. Opening a map or ride app on your plan never costs anything extra. ### Does the plan give me a Thai phone number? No. These plans are data only. Make calls and send messages through apps such as WhatsApp, and keep your home line on for texts with its data switched off if your bank sends codes by SMS. ### Does the plan work on a day trip to Ayutthaya or across the border? Ayutthaya, Kanchanaburi and Pattaya are all in Thailand, so the plan covers them. A trip across the border to Cambodia or Laos is not covered, because the Thailand plan does not cover the other country there. - [All Thailand eSIM plans](https://simorago.com/en/esim/thailand.md) - [Full Thailand guide](https://simorago.com/en/esim/thailand/details.md) - [eSIM for Phuket](https://simorago.com/en/esim/thailand/phuket.md) Source: https://simorago.com/en/esim/thailand/bangkok
