Frequently Asked Questions
Before You Buy
Will the eSIM work on my phone?
Your phone must support eSIM and must not be carrier-locked. iPhone XS, XS
Max, XR and later, most iPad Pro / Air / mini models, and recent Samsung
and Google Pixel phones are supported. iPhones and iPads sold in Mainland
China, Hong Kong SAR and Macao SAR generally do not support eSIM. Still
unsure? Check our compatible device list.
How fast is the network?
Most destinations run on 4G /5G. Available speeds vary by country and
local operator, and are shown on each plan page.
Do I need to turn on data roaming?
Yes. Turn on data roaming in your settings after installing the eSIM
(Settings > Cellular > Data Roaming), and switch it off when you get
home. This is what lets the eSIM connect to a local network abroad.
Ordering & Delivery
How soon will I get my eSIM?
We email your eSIM QR code to the address you used at checkout. Order on
the day you travel and it arrives within 5-10 minutes. Order more than two days
ahead and we send it the day before you depart.
I haven't received my QR code. What should I do?
Check your spam folder first. If it still hasn't arrived, contact us with
your order number and we will resend it to your email address.
Can I scan the same QR code on more than one phone?
No. The eSIM is bound to the first phone that scans it, and it can only be
downloaded a limited number of times. If you delete the eSIM from your
phone, it cannot be reinstalled.
Do I need to register my ID?
Yes — but only if you will use your eSIM in Hong Kong (China) or Taiwan (China). Local regulations require every SIM card to be registered under the user's own name before service can be activated in these two regions, so please complete the registration before you start using your plan. If your trip does not include Hong Kong (China) or Taiwan (China), there is nothing you need to do — Macao does not currently require ID registration.

We recommend completing it before you depart. If you have already arrived, connect to any Wi-Fi and finish it on the spot — it only takes a few minutes.
What you will need:
- Your passport — a clear photo of the full information page, including the barcode at the bottom. Lay it flat, keep it unobstructed, and avoid glare and shadows.
- Your eSIM ICCID — the serial number that starts with 8985234. It is listed in the QR code email we sent you. If you cannot find it, email us at cs@uhuibao.com and we will send it to you.
A few things to note:
- You must be 16 or older to register.
- Document photos are verified automatically. If a photo does not meet the requirements, the registration will be rejected and you will be notified by SMS and email — you can simply upload a new photo and try again.
- Your information is used only for identity verification.
Setup
How do I install it on an iPhone or iPad?
Open Settings > Cellular > Add Cellular Plan, then scan the QR code
with a phone connected to Wi-Fi or mobile data. Step-by-step instructions
are on our setup page.
How do I install it on a Samsung or Android phone?
Open Settings > Connections > SIM Card Manager > Add Mobile Plan,
then scan the QR code. Full instructions are on our setup page.
Using Your Plan
Can I make calls or send SMS?
No. Our plans are data-only. To make calls, use apps such as WhatsApp,
WeChat or Zoom over your eSIM data connection.
Can I check how much data I have left?
Not at the moment — a usage meter is not yet available for our eSIM plans.
We are working on it.
Can I install the same eSIM on a second phone?
No. Each eSIM can be activated on one handset only. If you need coverage
for two phones, please buy a second plan.
Refunds
Can I get a refund?
Yes. You can request a full refund at any time before your QR code has
been emailed to you. Once the QR code has been sent, the order can no
longer be refunded — even if you haven't installed it yet.
