Getting online in Hawaii
Hawaii is a US state: if your phone plan is American, it already works here and you don't need a travel eSIM. Visiting from Australia, Canada, the UK or New Zealand? Hawaii is covered by our United States eSIM. Install it at home and you're online when you land in Honolulu, then on Maui, the Big Island and Kauai.

Honolulu, Oahu
Your eSIM connects
As soon as your phone finds a local network. Set the eSIM as your data line and turn on data roaming for it.
