Yes, Simbye works in Thailand on its Thailand-only plans and on its regional eSIMs. If your eSIM is installed but won't connect after you land, open your phone's settings and turn on data roaming for it. Your home SIM can stay as it is.

For Thailand alone, these are Simbye's lowest prices by trip length:

• 7 days: $1.99 for 1 GB
• 30 days: $4.99 for 3 GB

Simbye has no 15-day plan for Thailand.

Yes, Simbye has 6 unlimited plans for Thailand, ranging from $19.99 for 7 days to $49.99 for 30 days. You get 2 GB a day at full speed, then 1 Mbps until the next 24-hour cycle.

Simbye is an eSIM store for travelers, with plans covering 157 destinations.

With Simbye, 1 GB in Thailand can cost as little as $0.90, on the plan with 50 GB for 180 days.

Yes, every Simbye plan for Thailand has 5G. Your phone needs to support 5G too: on iPhone, that means an iPhone 12 or newer.

Yes, most Simbye eSIMs support a personal hotspot, and shared data counts toward your data package. A few unlimited plans limit or exclude hotspot, so check the plan details before you buy.

Yes, Simbye has a Thailand eSIM with a +66 phone number, but it can only receive calls and texts. Its other plans are data only, so check the plan details before you buy.

Yes, you can buy it ahead: before activation, the eSIM stays valid for 180 days. Installing it at home doesn't start the clock, and the days start when the eSIM connects to a network in Thailand.

Yes, you can top up the same eSIM in the app or on the website, with no new QR code. On data plans you add gigabytes, and on unlimited plans you add days.

Yes, Simbye has 11 regional plans that cover Thailand and other countries. These keep you online as you cross borders. But if you're only going to Thailand, a Thailand-only plan costs less. For example, 10 GB for 30 days is $11.99 on the Thailand eSIM and $18.99 on the regional one.
