Flexiroam

A year-long posting abroad doesn't fit neatly into the 7 or 30-day validity windows most travel eSIMs are built around, and Flexiroam is one of the few providers that explicitly addresses that with plans running up to 365 days. Operating since 2011 and listed on the Australian Securities Exchange since 2015, it also brings a level of financial transparency, audited results, quarterly filings, that a smaller nomad-focused reseller can't match, worth something if you're trusting a company to keep your connectivity working for a full year.

Its hybrid product pairs a physical SIM with an eSIM profile, useful for someone who wants a backup that doesn't depend entirely on their phone's eSIM slot working correctly. Unlimited plans carry a disclosed fair-use cap of 2 to 3GB of full-speed data per day, and both data-only and separate voice-and-text plans are available depending on whether you need to be reachable on a real number. Refunds carry a 5% admin fee and often come back as wallet credit rather than cash. It's a strong fit for a long-stay expat or remote worker settling into a single country for months rather than weeks.
