I'm planning a three-week backpacking trip through Thailand, Vietnam, and Cambodia starting next month. I'll mostly use my phone for maps, messaging, and booking hostels, with maybe some social media. I want to know if there's one regional plan that covers all three countries well or if I should get separate ones.

I did a similar trip last year and used the Asia Pacific plan from eSIM TopUp. It worked great in all three countries and I didn't have to switch anything. Just make sure your phone is unlocked before you go.

For a three-week trip covering Thailand, Vietnam, and Cambodia, our Asia Pacific regional plan is the best fit. It covers all three countries with a single data package, and you can top up in the app if you run low.

I found that coverage in rural areas of Cambodia was a bit spotty, but in cities it was fine. If you're sticking to main backpacker routes, the regional plan should be plenty.

Don't forget that some local SIMs are cheaper if you're staying in one country for a while, but for multi-country the eSIM is way more convenient. I used about 2GB per week with heavy maps and messaging.

I'd recommend the 10GB plan for three weeks. I streamed music and used maps constantly and still had data left. You can always top up if needed.

If you're a heavy data user, consider our 20GB Asia Pacific plan. It's valid for 30 days, so it covers your whole trip. Just install the eSIM before you fly and it'll activate when you connect in Asia.

I loved that I could keep my WhatsApp number active for hostel bookings while using the eSIM for data. No issues at all in Thailand and Vietnam.

Check if your phone supports eSIM before buying. My older phone didn't, so I had to use a physical SIM. Otherwise, the regional plan is the way to go.
