Simify

Simify started life as SimsDirect, a company that shipped physical prepaid SIM cards to travelers before eSIM adoption took off, and has since rebranded and moved to an eSIM-only model out of its Australian base. Coverage runs to roughly 128 countries on its Global plan, with tighter regional packs like Europe and the UK at 51 countries and Southeast Asia at 11.

Pricing is day-based rather than per-gigabyte, generally $1.16 to $2.61 a day depending on the plan, with validity stretching up to 180 days on some options, longer than most short-trip competitors bother offering. Its "unlimited" plans exist but run on an undisclosed fair-use cap, so treat the label with the same caution you'd apply anywhere else in this category. Everything here is data-only, and there's no in-app top-up yet, you'll need to buy a new eSIM if you run out. A genuine 100% money-back guarantee applies for an incompatible device, a cancelled trip, or a real coverage failure, though not for issues caused by misconfiguring the eSIM yourself. It's a good option for backpackers and simple day-rate budgeting, especially for anyone traveling to or from Australia.
