As we drove up the mountain side, it started to rain heavily several times and we got quite wet, so I wish we had brought raincoats. The guide was very good at taking photos, so it was a great memory!
Overall, the experience using the US eSIM was great. Installation was simple; just scan the QR code to activate it immediately, no physical SIM card needed. Internet speeds in the US were stable, and daily use of Google Maps, LINE, and WhatsApp was smooth with no lag. Unlimited data in the US is incredibly convenient, eliminating worries about extra charges. Voice calling was also very useful, working seamlessly whether making local calls or returning to Taiwan. The only thing to note is to ensure your phone supports eSIM during initial setup. Overall, the price is reasonable, and I highly recommend it for long-distance travelers!
