Rated 5 out of 5 stars

Simple and straightforward

I travel often, so I've used PrimaSIM for a while. It's straightforward, the 2GB for £7 is fair, and adding more data is simple. If you don't activate the plan, the money stays in your account for later. The only downsides: you need an eSIM-ready phone and a little tech patience. Data-only, but WhatsApp and Messenger work fine as long as both people have the app.

Simple activation and good price

PrimaSIM has worked well for me in Canada, Switzerland, Austria, Belgium and even Iceland. Clear instructions, simple activation, and the 3 GB package for £10 was perfect

Never switched since discovering

Our son showed us Primasim a few years ago, and we've never switched. It's easy even for retired seniors. We keep recommending it to our travel group and family.
