1. Purchasing Your USIMSA Thailand eSIM

My spontaneous trip to Chiang Mai meant I needed a reliable eSIM for Thailand. Naturally, I turned to USIMSA, my go-to provider!
When you search for Thailand, various options pop up. Since I was only visiting Thailand, I chose a Thailand-specific plan. However, if you're backpacking or exploring multiple Southeast Asian countries, it's smarter to pick a plan that covers all your destinations.
What really impressed me lately is the availability of unlimited data eSIM plans. More and more travelers are using VPNs abroad to stream their favorite shows and movies, which naturally consumes a lot of data.
Thailand now offers unlimited plans too! You typically choose between a 'roaming network' plan and a 'local network' plan. I opted for the local network.
The roaming network had the perk of free Google Maps usage, while the local network was dubbed 'bullet-speed local network.' It was a tough choice, but I decided to give the local network a shot.
2. Activating Thailand's Bullet Local Network eSIM Domestically
My 'bullet local network' eSIM stated it couldn't be installed domestically. I usually prefer pre-installing before I leave to avoid any airport hassle, so I was a bit flustered at first.
However, I realized I could install it at home and just avoid activating roaming until I arrived. So, I scanned the QR code to set it up. Be warned: your plan's validity starts the moment you scan the QR code! Definitely install it once you're in Thailand! I recommend using the airport's Wi-Fi briefly for the setup.
Despite my attempts, it just kept saying 'activating' and never fully connected. So, I just scanned the QR to get the eSIM recognized, but kept the line turned off.
3. Using USIMSA eSIM in Chiang Mai, Thailand
As soon as I landed at the airport, I turned on the line and activated roaming. It connected instantly! With cellular data set to use the USIMSA eSIM, I was good to go.
Arriving safely at the airport and hailing a taxi was a breeze. It's truly a nightmare when your data doesn't work right after landing in a new country. Thankfully, I've never had an issue with USIMSA eSIMs activating immediately upon arrival, which always puts my mind at ease.
Even on my tour from Chiang Mai to Chiang Rai, the data connection was flawless. I even streamed videos via VPN without any interruptions during the journey.
I even ran a data speed test. Uploading videos to social media was completely seamless. It really confirmed that this 'bullet local network' lives up to its name!
My USIMSA eSIM for Chiang Mai, Thailand, worked perfectly throughout my trip! Whether I was paying with GLN at the night markets or using Grab for taxis, everything was quick and smooth.

Thailand Mueang Chiang Mai District, Chiang Mai
According to the article, the USIMSA Thailand 'Bullet Local Network' eSIM cannot be installed in Korea. Since the service period begins the moment the QR code is scanned, it must be installed locally in Thailand. We recommend using the local airport Wi-Fi briefly for installation.
The article mentions that the 'Roaming Network' has the advantage of allowing free use of Google Maps. On the other hand, the 'Local Network' is called the 'Bullet Local Network' and is characterized by its high speed. You can choose based on your usage purpose.
According to the article, data worked well even after arriving at Chiang Mai Airport for catching a taxi or during a tour to Chiang Rai. It was also convenient for making payments with GLN at night markets or using GrabTaxi. Watching videos via VPN and uploading SNS videos were also smooth.
