 United States | Verizon | 5G |
Good to know

- Plans start when you first connect; install within 180 days
- Your data routes through United Kingdom or Norway, so some sites may show that country
Which networks does the Australia, UK & US eSIM use?
Three countries, one eSIM, and 5G in all three. Your phone switches to the local network by itself when you land, so there's nothing to swap at the border.

Your eSIM joins these networks in busy places like New York City, Los Angeles, London, Manchester, Sydney, Melbourne and Perth. Cities and main roads are well covered, but signal can thin out in the Outback, the Scottish Highlands and US national parks.
Your data reaches the internet through the United Kingdom or Norway, a normal setup for travel eSIMs. Read how IP addresses work abroad.
