How “Unlimited” works: Never cut off — each plan gives a set amount of full-speed data, then a slower speed. The exact allowance and speed are shown on every plan.Read more
Unlimited plans never run out and your eSIM is never disconnected, but every one has a fair-use limit: a set amount of full-speed data, after which the speed is reduced. The amounts differ between plans — most give a daily full-speed allowance that refills every 24 hours from when you first activate the eSIM, while Premium plans give a larger allowance for the whole plan instead. Each plan states its own allowance and the speed after it before you buy. At the reduced speed, messaging, maps, email and light browsing still work; video streaming and video calls may not. If you want every gigabyte at full speed, choose a fixed-GB plan.

Before you buy
What happens if something goes wrong
You are buying data for a trip that has not happened yet, from a company you met a minute ago. Here is where you stand if Cambodia does not go to plan.
Refund if you never install it
Plans change. If you have not installed the eSIM, ask for your money back within 5 days of buying from your Order History page. Once a profile is installed on a phone it cannot be taken back, so that is where the line sits.
A person answers, within 24 hours
Seven days a week, including while you are away. [email protected], or the form on our support page.
Check your phone before you pay
An eSIM needs a phone that supports one and is not carrier-locked. Look yours up in 10 seconds — it is worth doing first.
One payment, no subscription
You buy a plan once. Nothing renews, nothing is stored to charge later, and every fee is shown before you pay. Card, Apple Pay or Google Pay, handled by Stripe — your card details never touch our servers.
Siima plans run on eSIM Go's network of local operator agreements — the same infrastructure behind many travel eSIM brands. Plans are data-only: you get no Cambodia phone number, so keep your home SIM on for calls and texts.
