How to Install and Activate Your eSIM

Follow these simple steps to get connected before your trip

1

Check Device Compatibility

Make sure your phone supports eSIM. Compatible devices include iPhone XR/XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Your phone must also be carrier-unlocked - if you bought it on a contract, check with your carrier before you travel.
2

Purchase Your Plan

Browse eSIM plans by destination on aviaesim.com and pick the one that fits your trip. The moment payment clears, your QR code arrives by email and shows up in your account dashboard.
3

Scan the QR Code

On iPhone: Settings → Cellular → Add Cellular Plan → Use QR Code. On Samsung: Settings → Connections → SIM Manager → Add eSIM. On Google Pixel: Settings → Network & Internet → SIMs → Add eSIM. Point your camera at the QR code and follow the on-screen prompts.
4

Label and Configure Your Plan

Give your new eSIM a clear label like 'Travel Europe' or 'Thailand Trip'. Keep your physical SIM as the default line for calls and SMS, and set the new eSIM as the default for mobile data - your apps will use travel data while you're abroad.
5

Switch It On at Your Destination

Once you land, open your eSIM settings and turn on the eSIM line. Switch on Data Roaming if prompted. The eSIM connects to a local network automatically within a few minutes - no store visit, no SIM swap.

💡 Pro tip: install your eSIM on home Wi-Fi days before you fly. The plan only starts counting down once you first connect to a local network at your destination - so there's no rush to activate.

What Our Customers Say

Spent three weeks traveling between Thailand and South Korea and the aviaesim regional plan covered both countries without any extra cost. In Bangkok the speeds were impressive - I had no trouble with video calls or uploading photos. The whole experience was seamless from purchase to connection.

Japan trip with a group of friends - everyone bought their eSIM from aviaesim and we were all online before leaving the airport. In Tokyo the connection was 4G the whole time, even on the bullet train between cities. Saved a huge amount compared to what our carrier quoted us for roaming.

I was skeptical at first because I had never used an eSIM before, but installing it on my Samsung Galaxy S21 took about three minutes. Traveled to Singapore and Malaysia and the signal never dropped. The customer support team answered my question on WhatsApp within ten minutes. Great service.

One Asia eSIM for the whole region — Tokyo to Bangkok to Bali

A travel eSIM for Asia replaces the country-by-country SIM hunt with a single QR code that works from Japan to Indonesia. Roaming on a US, EU or Australian carrier across Asia runs $10–15/day per country — for a Southeast Asia loop hitting Thailand, Vietnam, Malaysia, Singapore, that's $200+ in a week. Buying local SIMs means a passport scan and a 7-Eleven visit at every airport. An Asia eSIM card connects on the same NTT Docomo, KDDI, AIS, dtac, Viettel, Singtel and Telkomsel networks the locals use — same towers, same speed — but activates from your hotel WiFi before you board your next flight. Pick 5GB for a one-country trip, 10–20GB for a multi-country itinerary, or unlimited Asia eSIM coverage for backpackers on a 30-day RTW.

Asia eSIM vs local SIM cards vs roaming

Three options for staying online across Asia. Local SIMs are cheap per country but eat hours at airport kiosks; carrier roaming is fast but ruinous over multiple countries; an Asia eSIM combines coverage with the price of a single prepaid SIM.

More questions about Asia eSIM

Which Asian countries does the eSIM cover?

Most Asia eSIMs cover 30+ countries: Japan, South Korea, Taiwan, Hong Kong, Macau, China (with VPN-friendly routing on some plans), Singapore, Malaysia, Thailand, Vietnam, Indonesia, Philippines, Cambodia, Laos, Myanmar, Sri Lanka, India, Nepal, Bangladesh, Pakistan, Maldives, Bhutan, plus Central Asia (Kazakhstan, Uzbekistan, Kyrgyzstan).

Will an Asia eSIM bypass China's firewall?

Some Asia eSIM plans route through Hong Kong or Singapore networks, which means Google, WhatsApp, Instagram and Gmail work without a VPN inside mainland China. Always check the plan description for "China-friendly" or "international routing" — standard local-SIM coverage will still hit the GFW.

Is unlimited Asia eSIM truly unlimited?

Unlimited Asia eSIMs run at full 4G/5G with a 3 GB/day fair-use cap, then throttle to 1 Mbps until midnight UTC. That covers normal travel use (maps, messaging, social, video calls). Streaming 4K Netflix all day will hit the cap; everything else is fine.

Best eSIM for Southeast Asia specifically — Thailand, Vietnam, Cambodia, Laos?

A regional Southeast Asia eSIM covers all four plus Malaysia, Singapore, Indonesia, Philippines and Myanmar at the price of one country's SIM. Particularly useful on the Banana Pancake Trail (BKK → Siem Reap → Vientiane → Hanoi) where local SIMs reset every border.
