Before you choose a plan
What is the difference between a Daily plan and Total GB?
A Daily plan renews its daily high-speed allowance at the reset time stated for that product. Total GB is one high-speed data allowance shared across the whole validity period. Treat a Total plan as no longer usable once its high-speed allowance is exhausted. Do not rely on a 128kbps connection for normal internet use.
Does every eSIM start its validity when I reach the destination?
No. Activation rules vary by product. Malaysia CelcomDigi eSIM validity starts being calculated as soon as the eSIM is issued, counting from the following day. Do not buy too early; read the product warning. Roaming plans require data roaming to be switched on at the destination.
How are physical SIM cards delivered?
Physical SIM cards include free nationwide shipping within Malaysia and Thailand. Order early: public holidays, weather and courier delays can affect arrival. Choose a delivery address in one of these two countries and allow time before departure.
Is a local SIM the same as a roaming SIM?
No. Network access, setup and coverage depend on the specific plan. Follow the APN and activation instructions supplied with your order. Turn on data roaming for roaming plans, and check the listed countries and any excluded areas before buying.
Where it works

🌐 Three UK + Europe Travel eSIM — UK's own network + Europe roaming
📶 Three UK is a LOCAL UK network (not roaming while in the UK). 5G/4G, auto network-select. APN: three.co.uk.
📊 HOW THE DATA WORKS — please read:
Each plan is ONE shared pool = your total data. The EU/roaming figure is a CAP on how much of that pool you may use OUTSIDE the UK — NOT extra data.
Example — 40GB plan (EU cap 6GB): after 6GB used in Europe, 34GB remains but is usable only in the UK. In the UK: full speed until the pool runs out.
📞 CALLS & TEXTS — 200 minutes of calls + SMS included:
• UK: data + calls + texts.
• Europe (41 destinations): data + calls + texts — call from any EU country to another EU country, or back to the UK.
• ⚠️ From the UK you CANNOT call Europe (UK numbers only while in the UK).
• Other 28 destinations: DATA ONLY (no calls/texts).
🗺️ SUPPORTED DESTINATIONS:
