Pick the date you arrive in Malaysia when you order.
We email your eSIM QR code about 48 hours before you land (right away if you arrive within 2 days). Add your WhatsApp number (optional) to get it there too.
Install the eSIM on strong Wi-Fi before you fly — do not delete it after installing.
Your plan days start on your arrival date (Malaysia time). Travel dates changed? Use the link in your confirmation email any time before the QR is sent.
Good to know
Your phone must support eSIM and be carrier-unlocked. Dial *#06# — if you see an EID, your phone supports eSIM.
Malaysia + SEA: outside Malaysia, turn on Data Roaming. APN: celcom3g.
For travel data and calls only — it can't be used to register local apps or e-wallets, or to receive verification codes (OTP/TAC).
I haven't received my QR code yet. It is emailed about 48 hours before your arrival date (right away if you arrive within 2 days). Please also check your spam folder.
The QR code won't scan or the installation failed. Your phone must support eSIM and be carrier-unlocked — dial *#06#; if you see an EID, eSIM is supported. Install on strong, stable Wi-Fi. If it still fails, contact us before trying again.
Installed, but no signal or data in Malaysia. Turn on the CelcomDigi line and select it for Mobile Data. Toggle Airplane Mode on and off, or restart your phone. If needed, set the APN to celcom3g (no username or password).
Using it outside Malaysia (Malaysia + SEA plan)? Turn on Data Roaming in your phone settings.
Still not working? Contact us with your order number and a screenshot — WhatsApp (button on this page) or support@happytravelsim.com. ⚠️ Do NOT delete the eSIM: it can only be installed once. If our support team confirms a fault that cannot be fixed, you can request a refund review under our Refund Policy.
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. For the Malaysia CelcomDigi eSIM, choose your arrival date at checkout: we email the QR code about 48 hours before you land, and your plan days start on your arrival date. 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.
