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!
Before going, I hadn't done any research and thought it was just a jellyfish exhibit. Turns out, it also has other fish, including three large tanks showcasing deep-sea species.
The star attraction is three manta rays. They often play together, constantly circling and spinning in the tank—so cute! Definitely worth seeing, super awesome!
I must mention their popcorn; it's incredibly delicious! I spent two to three hours in the exhibit, bought some to try, and it was surprisingly good!
It was easy to organize transportation to USS, entry was smooth and water world was the highlight of the day
