One eSIM, 51 Asian Countries
esimbloom's regional Asia plans give you prepaid mobile data across 51 countries including China, Japan, India, Thailand, the UAE, Singapore, and South Korea. The plan connects you to local networks in each country you visit, so you have data the moment you land. No need to swap SIMs at the airport or hunt for Wi-Fi.
Every plan is data-only. You can use messaging apps, maps, ride-hailing, and email, but there is no local phone number for voice calls or SMS. The eSIM works on 4G/LTE and 5G where the underlying network and your device support it, and you can top up or extend your plan if you need more data or days.
How to Set Up Your Asia eSIM
Check that your phone supports eSIM—most iPhones from XS onward and recent Samsung, Google Pixel, and other flagship Android devices do. Buy your plan on esimbloom, and you will receive a QR code by email within minutes. Scan the code in your phone's settings to install the eSIM before you travel.
Activate the plan when you arrive in your first Asian country by turning on the eSIM data line. Your phone will connect to a local network automatically. Keep your home SIM active if you need to receive verification codes, and switch your data to the eSIM. Installation takes a few minutes; activation is instant.
Staying Connected Across Asia
Asia's cities—Tokyo, Seoul, Bangkok, Dubai, Mumbai, Hong Kong—have strong mobile coverage and you will stay connected on metro systems, in hotels, and across business districts. Many travellers move between countries on the same trip, and a regional plan means uninterrupted data whether you are crossing from Thailand to Vietnam or flying from Singapore to Bali.
Rural and mountainous areas vary. Expect reliable coverage along major highways and in popular tourist regions like Bali's Ubud, Japan's Kyoto, or India's Rajasthan circuit. Remote trekking routes in Nepal or the Himalayas, desert interiors in Oman, and offshore islands may have limited signal. For typical travel—navigation, translation apps, accommodation check-ins, and ride bookings—a multi-day data plan handles daily use without running out mid-trip.
Frequently asked questions
Does the Asia eSIM work in China?
Yes, esimbloom's Asia regional plan covers China. You will have mobile data without needing a VPN to install the eSIM, though access to some services may depend on local regulations and the network in use.
Can I use the same eSIM in multiple Asian countries?
Yes. The regional plan covers 51 countries and switches networks automatically when you cross borders. You do not need to buy separate plans for each country or manually change settings.
Will I get a local phone number with my Asia eSIM?
No. esimbloom plans are data-only, so you will not have a local number for calls or SMS. Use WhatsApp, FaceTime, or other internet-based apps for communication instead.
When should I activate my Asia eSIM?
Activate the plan when you land in your first Asian country and need mobile data. The validity period starts from activation, not from purchase, so install the eSIM at home but turn it on only when you arrive.
How much data do I need for a two-week trip across Asia?
For maps, messaging, and occasional photo uploads, most travellers use one to three gigabytes per week. Streaming video or uploading large files will use more. Choose a plan that covers your expected use and duration.
