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.
Where it works
China · Hong Kong · Macau
Daily 5GB covers Mainland China and Hong Kong only: Macau is excluded. Other listed plans cover all three. Google, WhatsApp and YouTube work without installing a VPN. This product does not support TikTok or ChatGPT. Unlimited plans do not support hotspot.
Make your data work for your trip
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.
Total GB · Data for the whole trip
Illustrative example
Example: Total 5GB for 5 days gives you 5GB for all 5 days combined, not 5GB each day. Use 2GB today and 3GB remains for the rest of the plan. It does not reset tomorrow. Treat the plan as offline once the high-speed data is used.
Unlimited does not mean unlimited full speed. Check the speed cap and hotspot conditions for the selected 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).
Follow the selected plan's setup instructions above. Roaming services require Data Roaming ON; local-plan exceptions are shown with your selection.
Actual signal and speed vary by location, device and network conditions.
Full product specifications
🌐 China · Hong Kong · Macau Travel eSIM
One eSIM for Mainland China, Hong Kong & Macau — and it works in China WITHOUT a VPN.
🌐 Runs on China Unicom — one of China · Hong Kong · Macau's top local networks, auto-selecting the strongest signal. In Macau it connects through CTM.
🚀 No VPN needed in China — Google, WhatsApp, Instagram, Gmail, YouTube & Xiaohongshu (小红书) all work normally.
📊 Plan Types
🚀 Daily — a fresh batch of high-speed data every day, renewing whether or not you used yesterday's.
📦 Total GB — one fixed data pool, use it anytime at your own pace, no daily cap. Runs out → top up.
💡 How much data? 1GB/day = maps, chat, email. 2–3GB/day = video calls, photos. 5GB/day or more = heavy work use, streaming.
🔋 Check your remaining data anytime on the Happy Travel SIM website — Total GB plans can be topped up there too.
📩 How to get it: your eSIM QR code is emailed automatically to the address you enter at checkout — no need to leave a message. Not in your inbox? Check your spam folder.
⚠️ Please note
• 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).
• eSIM installs once and cannot be moved to another phone.
• 📡 Remember to turn ON Data Roaming when you arrive — otherwise you will have signal but no data.
• ⚡ “Unlimited 5MBPS / Unlimited 10MBPS” are high-allowance DAILY plans — full speed for the first 1GB each day, then 5Mbps / 10Mbps. Not unthrottled unlimited.
• 🇲🇴 The “DAILY 5GB-CN&HK ONLY” plan covers Mainland China & Hong Kong ONLY — it does NOT work in Macau. Every other plan covers all three.
• 📶 Hotspot / tethering works on Daily and Total GB plans — only the Unlimited plans (Unlimited 5MBPS / Unlimited 10MBPS) do NOT support hotspot / sharing.
• Data only — there is no phone number, so no calls or SMS.
• ⚠️ TikTok and ChatGPT do NOT work on this network. If you need them, please choose another product.

Value for Money:Yes
Coverage and speed were up to standard. The only 2 issues when comparing to certain e-sim sold by other seller is that the e-sim can't be installed while in home country where you have the mobile data, and needed to manually switching the network while travelling between the 3 locations, at least for iPhone.

maybe coverage CN unicom not strong at area GuangZhou, signal/internet not so stable, signal of phone is 3G and phone will auto enable 5G when plug in this eSim. after asking seller suggest change to LTE to get a bit better connection. overall should acceptable , but next time will select CN Mobile.
