First, three points. I purchased an eSIM with a local phone number from AIS. This requires identity verification and a 13-digit SIM card number. This can be done by entering the last 13 digits of the CCID sent from KKday. Second, the promotional offer of 15GB to 35GB over 7 days will be communicated via SNS once you arrive in Thailand and connect to the network. Third, the price. It would cost 399 baht to get a contract at the airport, but this was only about 800 yen, so it was a good deal. I'm also able to communicate using AIS's 5G network.
I have an iPhone, and after connecting to the airport Wi-Fi, it activated with just one touch, which was very easy to understand and use. It worked smoothly at my destination, except for occasional slowdowns. The price was also reasonable, and I would definitely use it again!
The setup was so easy that I almost accidentally set it up before arriving at my destination, so that's something to be careful about...
I had some trouble with the setup, but the quick response was very helpful.
I used it in three countries this time, and I was able to use it without any problems in every country.
This was my first time purchasing an eSIM from here. The setup was instantaneous, and I've been using it without any problems since arriving in Bangkok. The price is reasonable, and all you need is your smartphone, making it very convenient and comfortable to use. I will definitely buy from you again.
Easy to install and reasonably priced. I used it for five days in Bali. Except for the unstable signal on Nusa Penida, the internet speed was mostly acceptable in other areas. I would repurchase it if I have the chance.
