An eSIM, or embedded SIM, is a digital SIM that allows you to activate a cellular plan without needing a physical SIM card. In Spain, eSIMs can be used with compatible devices to connect to local networks, enabling you to access mobile data and make calls.
Easy to activate and connection is great so far.
Since this is a top-up product, you should not send an email asking the user to activate the eSIM again. Instead, simply send a message letting them know that new data has been added to the existing account. Your current process caused me to waste an hour attempting a "new" activation and contacting your support team.
