eSIM.net

eSIM.net was founded in London in July 2019 by a team that says it has roots in the GSMA working group that helped standardize eSIM technology, and its product reflects that carrier-side background more than most apps in this category. Rather than being purely data-only, eSIM.net sells full plans with voice minutes and SMS on top of data, built through partnerships with recognizable UK and European operators including O2, Vodafone, Three, EE, Orange, and Bouygues.

Its 76-plus country coverage skews toward the UK and Europe, and pricing includes both date-bounded travel eSIMs from roughly £6 to £32.50 and a rolling monthly UK plan starting at £6, aimed at people who want an ongoing UK number rather than a one-trip package. A USA plan with 30 days of "unlimited" data runs about £20.50, though eSIM.net doesn't publish the throttling terms, so treat that label with the usual caution. There's no credit check or ID requirement to sign up. Refund experiences reported by customers have been inconsistent, so it's worth reading the current terms before buying. It suits UK-based travelers heading around Europe and anyone who specifically wants real calling and texting rather than a data-only eSIM.
