Compare 43 eSIM options currently listed for Greater China, starting at $4.39 USD. Choose a validity period that covers your whole trip, then compare the data allowance and the conditions of the plan you want to buy.
Available validity periods: 3 days, 5 days, 7 days, 10 days, 15 days, 30 days. These are plan validity periods; check when the validity starts before installing or activating your chosen eSIM.
How much data do you need in Greater China?
Start with what you use away from Wi-Fi: maps, translation and messages need less data than video, video calls or a laptop hotspot. Check your phoneโs recent data usage for a useful baseline and leave room for travel days.
Daily-data plans: compare the high-speed allowance for each day and read what happens after it is used. A reduced-speed connection and a high-speed connection are different allowances.
Total-data plans: the allowance is shared across the validity period. This can suit uneven use, but a heavy day can leave less data for the rest of the trip.
Confirm the activation rule and expiry date for the selected plan. Installation does not have the same effect on every providerโs plan.
If you need a laptop connection, check hotspot support on the selected plan.
For a regional plan, confirm that every country on your route is included in its coverage list.
Questions about your Greater China eSIM
Can I keep my existing phone number?
On a compatible dual-SIM phone, you can use the travel eSIM for data alongside your home SIM. Keep data roaming off on the home SIM unless you intend to use it, and check your home carrierโs charges for calls and SMS abroad.
When should I install and activate the eSIM?
Read the instructions supplied with your selected plan before installing it. Use a reliable internet connection for installation, and check whether the validity starts at installation or when the eSIM connects to a supported network.
Can I order a physical SIM instead?
Physical SIM delivery is available within Vietnam. If you will not be in Vietnam before your trip, choose an eSIM for a compatible phone or contact support before ordering.
