The connection is easy and fast, and you can extend your usage without installation. The internet signal is very good, better than hotel Wi-Fi. I'll continue using this service.★

Once the slightly tricky verification is complete the service is mostly excellent. I had a few low reception spots but overall great.★

Setting up the eSIM was super easy — no physical SIM, just scan the QR code and it installs directly on my phone. TrueMove even supports multiple numbers per device, which is handy if you switch plans or travel often
Great 5G coverage in Bangkok, Phuket, and Chiang Mai, and worked smoothly for streaming, maps & social apps★

The SIM card worked perfectly, with easy-to-follow activation instructions. Significant savings compared to roaming costs. I used the SIM card in Borneo and Kuala Lumpur.★

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.
