Why a regional eSIM?
Crossing borders shouldn't mean swapping SIMs or buying a new plan in every country. One QR, all of Asia.
🌍
18 countries, 1 plan
Crosses every border in Asia. No new SIM at the airport. No setup at the next hotel.
📡
Auto-network handover
64 carrier partners. The eSIM picks the strongest local signal — automatically.
💸
No roaming fees
Pay once before you fly. The price you see is the price you pay — no surprises.
🔄
Top-up across borders
Running low in one country, finishing the trip in another? Top up once, works everywhere.
📱
Keep your home SIM
Data-only plan. Your home number stays active for calls and SMS in the second slot.
⚡
Instant activation
Install on Wi-Fi at home, connect the moment you land in any of the 18 countries.
How it works
From buy to bars across 18 countries.
No physical SIM, no border-crossing setup, no carrier hunt. One QR, the whole region.
01
Pick a regional bundle
Choose data-based or unlimited. Most Asia travelers pick 10 GB / 30 days.
02
Receive your QR
Instant email delivery. Saved to your account too — no need to print.
03
Install before you fly
Scan once on Wi-Fi. The eSIM downloads but stays dormant until you arrive in the region.
04
Land & connect — anywhere
Toggle data roaming on the eFlexsim line. Works the same way in all 18 countries.
05
Cross borders, stay connected
Networks switch automatically. No SMS prompts, no extra setup, no roaming surprises.
Regional vs single-country — which to pick?
If you're staying in one country the whole trip, a single-country plan is cheaper. If you'll cross 2+ borders, regional pays for itself.
