Wasn't able to connect in China. Not sure what the reason was. Also it requires connecting to activate in the desired country.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!

User friendly and stable connection! Road trip in West Australia and only experience a short period of poor connection while travelling in Cervantes.

Guest User2025-09-08

Overall, Trip.com's eSIM is very convenient to use in Gladstone, especially for short-term travelers who don't want to swap physical SIM cards. If you're traveling to the rural areas surrounding Gladstone, it's recommended to check coverage along your route or choose a carrier with wider coverage like Telstra. I'll definitely use Trip.com again for my next trip; it saves both time and effort!
