FAQ
Frequently asked questions
Everything about ordering, installing, using and topping up your Blitz eSIM — organised by topic, short and clear.
What is an eSIM?
An eSIM is a digital SIM card. You install it with a QR code or activation code — no physical SIM swapping, alongside your regular number.
When does my bundle start?
Validity only starts when your eSIM first connects to a network at your destination. Installing at home doesn't cost you any days.
Can I keep my WhatsApp number?
Yes. You use mobile data via the eSIM while WhatsApp stays linked to your existing phone number.
Should I install the eSIM before I leave?
We recommend it: install it at home over Wi-Fi and only enable the eSIM's data roaming on arrival. You'll be online right away.
Is my phone compatible?
Most devices from recent years support eSIM (iPhone XS or newer, recent Samsung Galaxy and Google Pixel). Check your settings under 'Add SIM'.
