My reason for buying one was to 'road test' an eSIM in the EU (where I would normally get free roaming woth my mobile provider in the UK) prior to a long trip to Canada later in the year where I will be 100% dependant on one. Easy purchase and delivery of the QR code was very quick. Installation onto my phone was straightforward. However, what are you supposed to do if you don't have a second device with a screen on to view the email? I was OK on this occasion as did the install before leaving home via another computer screen. My eSIM installation (on an Androd phone) allows you to skip past the scanning function and install via a code supplied by the operator either starting 1$ or LPA:1$ However neither of these are supplied by easySim. So this may be worth looking into. Going through the activation of the eSIM and setting your physical SIM to no longer be the default was a bit fiddly. Finally got it to work and after that, it was uninterupted data roaming - often at 5G and moving from one EU country to another was seemless. Got a couple of notications from easySim to say I has half of my quota used and nearly used up the data. So overall an good experience.
