Product photos & plan information
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. 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.

Daily GB · Data per day
Illustrative example
Example: Daily 1GB for 5 days gives you 1GB of high-speed data each day. Tomorrow brings a new 1GB allowance. You cannot use all 5GB on day one. Reset time and speed after the daily allowance depend on your plan.
Delivery & setup
Your eSIM QR code is sent to the email entered at checkout. Check device compatibility before ordering; install with a stable internet connection and do not delete it when troubleshooting.
eSIM: install within 180 days after the QR code is sent. Once installed, it must connect to the network at your destination within 30 days or it expires — your plan days start from that first connection (we suggest installing 1–2 days before you fly).

📊 Plan Types
🚀 Daily (1GB / 2GB) — a fresh batch of high-speed data every day. After the daily allowance, speed drops to 128kbps until the next reset.
⚡ Unlimited 10MBPS — the first 1GB each day at high speed, then unlimited at up to 10Mbps (may drop to 5Mbps) — not full speed. Comfortable for HD video and heavy browsing.
⚡ Unlimited 10MBPS+ — the first 2GB each day at high speed, then unlimited at up to 10Mbps (may drop to 5Mbps) — not full speed.
📦 Total GB (5GB / 8GB / 10GB / 15GB / 20GB / 30GB) — one fixed data pool, use it at your own pace with no daily cap. Runs out → top up.
🔋 Check remaining data or top up Total GB on the Happy Travel SIM website.
📡 Turn ON Data Roaming in your phone settings — without it you will have signal but no data.
📩 How to get it: the eSIM QR code is emailed automatically to the address on your order (check your spam folder if you don't see it).
⚠️ Good to know
• 📱 New Samsung phone? Some models are region-locked: before using an overseas SIM, make a 5-minute regular call (not an app call) with a local SIM from the phone's original sales region. Requirements vary by model — please confirm with Samsung.
• 📍 Thailand: not supported in the 4 deep-south provinces (Yala, Pattani, Narathiwat, Betong) — Hat Yai works.
• ⚠️ Installing the SIM/eSIM and turning on roaming while still in your departure country (e.g. Malaysia, Singapore, Thailand) may start the plan early.
• Data only — no phone number, no calls or SMS.
• eSIM: install within 30 days after the QR code is sent. Once installed, it must connect to the network at your destination within 30 days or it expires — your plan days start from that first connection (we suggest installing 1–2 days before you fly).
• Daily plans renew every 24 hours from the time you activate — not at midnight.
• Unlimited plans are speed-capped, not full speed, and cannot be used as a hotspot.
• Daily and Total GB plans can be used as a mobile hotspot.
