Thank you, everything works, the modem is distributing data. Keep in mind that you won't get an Indraif number unless you register for one. It's only for the internet, unless you get a great price.

Reviews: Thailand AIS | 5G eSIM | Total Package | 7 Days | Real-Name Authentication Required | Supports Tiktok & ChatGPT | Natural Day Billing | QR code
Guest User2025-11-14
Good afternoon, my husband and I bought two e-SIM cards. We installed them, and everything works perfectly. The only problem we had was the installation: it wasn't immediately clear where the QR code came from, which numbers needed to be entered where, and where to find them. After opening the QR document and reading the full instructions, everything became clear. I'd like to see some minor adjustments to the setup instructions in the purchase description. You say you need to confirm authentication first, then purchase. In reality, you need to purchase first, wait for the reservation to be confirmed, and only then open the document (which also doesn't display) and create the SIM card.

Reviews: Mainland China 5G eSIM | Day Pass/Total Data Package | ChatGPT Available | 24-Hour Billing | 1-365 Days | QR Code

Before using this, I activated roaming on my phone from a network in Thailand, but when I arrived in China, I encountered problems that they couldn't resolve. However, after buying this eSIM, not only did it solve my internet problems, but it also allowed me to use the internet in China very quickly and cheaply. I think it's incredibly worthwhile, much better than roaming, and the internet is super fast.

Gone to Thailand for few days and needed a sim card that works. This worked well without any issues. Signal was very good! Will use it again next time.

It's inexpensive and easy to set up. While China has restrictions on using foreign apps, this eSIM comes with a VPN pre-configured, so you can safely browse foreign websites.
