First, check here if your device is already equipped with a Ubigi eSIM. If yes, the only thing you have to do is to connect your device to the Ubigi network and create your Ubigi account.
If there is no Ubigi eSIM profile preinstalled on your laptop or tablet, or if you have deleted it by mistake, you can automatically install/reinstall a new one for free by following instructions here.
You’ll be connected to the internet within minutes!
If your mobile device is SIM locked by your operator, you won’t be able to install Ubigi.
