Rated Great 4.2 / 5 · verified reviews
The eSIM was easy to install. It gave plenty of data and cost a reasonable amount. From Keflavik to Hofn I basically did not lose service once.
Easy to use and great coverage in Canada & USA for the price.
The internet quality of the eSIM was impressive, just as I had expected, and the setup process was extremely straightforward.
eSIM stands for “embedded SIM”, because everything you need is digitally built into your smartphone or tablet. Think of it as the evolution of the SIM card - it’s just like your old SIM, but better! Now there are no tiny holes or bits of plastic to deal with, so you never have to think about swapping out SIM cards again. Wave goodbye to the old and say hello to the future of mobile connectivity!
You can’t make regular network calls or send SMS with your eSIM, but you can keep your existing SIM active if you still want access to these services. Just make sure you confirm any charges with your network provider before you travel. And remember, while breeze eSIM plans are designed just for data, you can still use messaging and voice apps like WhatsApp, Messenger, iMessage and more. These apps all work great with the data connection your breeze eSIM provides.
Setting up your eSIM is easy, and we’ll send a step by step guide after purchase. Or, you can head to our eSIM installation guide here.
First, you need to make sure you’ve got a reliable internet connection, so make sure you’re connected to Wi-Fi. Go to Settings > Mobile Data > Add Data Plan. This can vary depending on your model, so if you can’t see this option, find your steps here.
We’ll send you regular updates and you can check the data used on your eSIM in the My Account area of your breeze login.
