One city, one week: sizing the plan
This is the most predictable kind of trip, so the choice can be precise.
En bref
- A single-country plan whose validity covers the whole week including the return day is usually the closest fit.
- Estimate from your own daily usage, then subtract what accommodation Wi-Fi will absorb.

Questions fréquentes
How far ahead should I buy?+
One to two days ahead works well: time to fix any problem on home Wi-Fi, without being so early that you forget to check.
If the accommodation has good Wi-Fi, do I still need a plan?+
Yes, because the moments you need data most are outside: navigating, hailing rides and looking things up on the move.
For a one-week trip, should I buy seven days or ten?+
Count from the hour you land to the hour you leave for the airport. If that stretch exceeds seven full days even by a few hours, take the longer window: being without data on the day you travel home causes more trouble than the price difference.
Do I need an unlimited plan for a single-city trip?+
Usually not, because the heavy use tends to land on the accommodation Wi-Fi. Unlimited plans also carry conditions of their own, such as a speed cap after a certain point, and those differ between plans. Read the condition first, then compare it against the size your own statistics suggest.
What if I get it wrong and run out mid-trip?+
If the plan supports top-ups, add more as soon as it looks low rather than at zero, since topping up needs a connection. If it does not, buy a fresh plan over the accommodation Wi-Fi and select the new profile in your phone's settings.
Should I activate the eSIM in Thailand or wait until I land?+
Install while you are on Wi-Fi, but wait to activate until you arrive if the plan counts validity from first connection. The rule varies between plans, so read the plan page and follow the order it gives.
Can I share a hotspot with the person I am travelling with?+
It depends on the plan: some permit it and some restrict it, so check the plan details before buying and increase the allowance for the devices that will attach. Also consider the day you split up, when the person without a plan has no connection at all.
The accommodation advertises free Wi-Fi. Do I still need a plan?+
Yes, because the moments you need data most are outside: navigating, hailing rides, looking things up on the move. The quality of that Wi-Fi is also unknowable until you arrive, so a right-sized plan is the part you can control.
