Used it in HK, Japan (transit), USA, Mexico, and Canada and never had a problem with it. Only 4G but the speed was sufficient for my browsing needs which mostly consisted of google maps, messaging apps, tiktok, and google search. The free 15 minute call credit was also super useful. Will definitely repurchase in my next trip!
