Hi,
I am just wondering about U.S roaming data booster service.
Am I able to use data in Hawaii if I added on U.S roaming data booster in my phone?
It worked in Seattle trip last year but I am not sure I can still use it in Hawaii or it is better to buy USIM card in Hawaii instead?
any advice will be helpful.
+4US roaming boosters will work in Hawaii. You might experience issues due to the shutdown of 3G service in the US if you don't have an LTE phone or VoLTE is not enabled on your account though.
