eSIM Travel Tips for Honolulu
Honolulu is a popular Pacific stopover for Australians
Honolulu is a natural Pacific stopover for Australians on the way to the US mainland or visiting Hawaii as a standalone destination.

The crater summit trail has outdoor signal on the approach but can be patchier in rocky sections near the top.
Mountain trails can lose signal
Popular Oahu hikes including the Koko Head Crater Trail, Makapu'u Lighthouse Trail, and the Lanikai Pillbox Trail can have inconsistent signal in valleys and behind ridgelines. Download offline trail maps before starting any hike.
Neighbour island trips use the same eSIM

HelloRoam eSIM vs Telstra and Optus roaming in Honolulu
Cost comparison for Australians visiting Honolulu.
| Category | HelloRoam eSIM Recommended | US SIM card | Telco roaming (Telstra, Optus) |
|---|---|---|---|
| Typical cost | From A$4.07 total | — | $5–$10/day |
| Details | Plans start at A$4.07 for the US. Covers all of Oahu, all Hawaiian Islands, and the US mainland. Activate at home and arrive at HNL already connected. | Prepaid SIMs from T-Mobile or AT&T at Honolulu Airport cost USD$30 to USD$60 and require ID. An eSIM needs no ID and activates instantly from Australia without any in-store registration. | Telstra's International Day Pass adds a fee for every day you roam in the US.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
