Bangkok · Thailand
Staying online in Bangkok
Bangkok is a Grab city. The BTS is excellent on its corridor and irrelevant the moment your dinner is down a soi.
Before you land
Suvarnabhumi and Don Mueang both have public trains and a crowd of unofficial taxis. Install first, then open Grab or the official taxi desk. Do this before you walk outside.
Getting around
BTS and MRT cover the obvious hotels. Grab is the rest, and it needs data at the curb. River boats are a delight and a separate map pin.
Where the data actually goes
The river, Chinatown, and Ari are different cities in practice. A day in Ayutthaya is a train. Malls have wifi; the street where you actually eat often does not.
Which plan to buy
Heat and Grab mean you will use more data than a European walking city. The 10GB or 20GB plan is the one that still works on day six.
Practical notes
SIMs are sold at the airport for cash, which is the hassle an eSIM is supposed to skip. Plugs are type A, B, and C. Carry a little cash for markets.
