I activated the eSIM on the day I left the country. The eSIM setup was very convenient, and I didn't encounter any problems. The network was smooth, and the navigation didn't lag. I've used it many times; it's an essential for independent travel.
No Singapore domain is required; you can install it in Taiwan first! Since this SIM card can roam in Taiwan, you can test the installation by enabling data roaming while in Taiwan!
Follow the instructions on the website to select the start date, and you'll receive the eSIM in your email.
I installed it on the day I left the country, on my way to the airport. After clicking "register eSIM" in the email, I was redirected to the Singtel website. Scanning my passport and face completed the verification process! It took less than a minute! (No need to fill out any forms.)
Next, to install the eSIM, make sure you're in a Wi-Fi environment (you can use a family member's or friend's mobile hotspot). Then click "install eSIM" on the webpage. The rest is the standard eSIM installation process on your phone.
No special Singtel app is needed; a regular browser will suffice.
I was initially hesitant because of the low ratings, but since I had previously bought a physical Singtel SIM card at the airport, I decided to give it a try. I used the 10-day 4G plan, and I didn't encounter any lag issues; it was quite smooth! The price was also very affordable! You can give it a try!
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.
1. All-inclusive from market to table: Silom Cooking School takes you to a local market to learn about spices, how to make curry paste and stir-fry rice noodles by hand, and finally, to enjoy a table full of Thai food you've prepared – a truly satisfying experience.
2. Easy for beginners: Our humorous and patient instructors speak fluent English. Small class sizes allow even those with no experience to make authentic Tom Yum soup, green curry, and mango sticky rice.
3. Great value and a fantastic experience: Conveniently located, you can bring the taste of Bangkok home in just half a day – a must-do Bangkok experience that I recommend to everyone.
I bought KKDay's eSIM during my trip to Thailand. It's super convenient – buy and use immediately! The price is also great. It works perfectly and is fast. I'll definitely buy KKDay products from now on.
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.
Used during a trip to Seoul.
I installed it before the trip, and once I arrived, I was able to use it immediately just by turning on data roaming.
It connected without any problems even in busy areas, and since it's so affordable, I would like to use it 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.
The package is very convenient, ready to use, and cheap, in the distance has seen the three-headed elephant god, very shocking, the museum is pink as the main color, very beautiful and eye-catching, I built near the entrance side rented Thai stock, photography is more beautiful, and the weather is beautiful, no rain, and not very hot.
