Frequently Asked Questions
Can I buy an Asia eSIM in the UK before my trip?
Yes. Order it online from the UK, add it to your phone a day or two before departure while you have home broadband, and turn the line on once the plane touches down at your first stop, be it Bangkok, Tokyo or Singapore. Your UK SIM can stay in the phone for calls and bank texts. The phone must be unlocked: on an iPhone, Settings > General > About shows 'No SIM Restrictions' next to Carrier Lock if it is.

Is there one eSIM for China, Japan and Southeast Asia?
Yes, the wider Asia plans cover mainland China, Japan, South Korea and Southeast Asian countries such as Thailand, Vietnam and Malaysia on a single eSIM. Smaller regional plans skip some of them: a few cover only Singapore, Malaysia and Thailand, others leave Japan or China out. Mainland China, Hong Kong, Macau and Taiwan are separate entries in a plan's country list, so tick off every stop on your route.

What is the cheapest eSIM for Asia?
The cheapest Asia eSIM on MobiMatter costs $3.49 for 3 GB, valid for 7 days. Prices come live from 5 vetted providers and change often; the price on this page is the current one.
Is it worth getting an eSIM for Asia?
For most tourists and business travellers, yes, if your phone supports eSIM. Asia plans start at $3.49 for 3 GB, and you install the eSIM before you fly, so you have data when you land, without queuing for a tourist SIM at the airport. If your home plan already covers Asia at no extra cost, you may not need one.
Which eSIM is best for Asia?
Our best plan for Asia right now is 30 GB for 30 days at $14.99 from Three Hong Kong. We rank plans on quality and value for money, and this one comes first in the list.
How much data do I need for a week in Asia?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB
- Messaging and browsing: 50–150 MB
The cheapest Asia plan with at least 5 GB for a week or longer is 5 GB for 15 days at $4.99.
Do Asia eSIMs support 5G and hotspot?
5G is available on 42 plans for Asia, where the local network has 5G coverage; the others use 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Asia eSIM come with a phone number?
Most travel eSIMs, including most Asia plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Asia eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Asia eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

Mentions AsiaI’ve been travelling around SE Asia for the last 7 months, covering 6 different countries, and this app has been amazing throughout when needing to change eSIM. Very easy set-up when buying one and if you in fact are having some troubles, contacting the support team and talking through email takes no time at all. I was having some difficulty with an eSIM in Vietnam since my phone was not finding a signal no matter what I did - their support team helped me and guided me on different ways to fix it. Thank you!!

"Before every trip, my internet solution is definitely Mobimatter. It has never let me down. I once found myself without internet in the middle of a trip with another brand. Now, I don't take any chances; I stick to what I know."

In Turkey and Georgia in the summer of 2025, I used the app, and everything worked perfectly! The prices are cheaper than buying a SIM card at the airport.
