Which plan should you choose?

1 GB / 7 days (€2.99): Ideal for a short trip to one or two countries. Covers navigation, messaging, and light social media.
5 GB / 10 days (€19.99): The best choice for a multi-country itinerary of 1–2 weeks. Handles maps, social media, video calls, and moderate streaming.
10 GB / 30 days (€39.99): Best for extended travel across multiple countries, island-hopping, or travellers who use their phone as a hotspot for a laptop.

China with VPN Included

China is one of the 16 covered destinations — and UPeSIM's Asia plan includes a built-in VPN for China. This means you can access Google, WhatsApp, Instagram, YouTube, and all other services that are normally restricted in China, without setting up a separate VPN app.

This is one of UPeSIM's most competitive features. Most eSIM providers either do not cover China or cover it without VPN access. With UPeSIM, China connectivity works exactly as you would expect — open internet, no restrictions.

How the Multi-Country eSIM Works

You do not need to buy a separate eSIM for each country. Here is how it works:

Buy one Asia plan before departure on upesim.com or in the UPeSIM app.
Receive your QR code instantly by email or in the app.
Install on your iPhone or Android — scan the QR code in Settings → Mobile Service → Add eSIM.
Travel freely — when you cross into a new country, your eSIM automatically connects to the local network.
China: enable VPN in the UPeSIM app before entering China to access all websites freely.

Your data balance is shared across all countries. There is no per-country allocation — you use your GB wherever you need them.

Mobile Hotspot Across All Countries

All UPeSIM Asia plans include mobile hotspot (tethering). You can share your data connection with a laptop, tablet, or travel companions in any of the 16 covered countries at no extra cost.
