Question 1

What is an eSIM and how is it different?

Accepted Answer

An eSIM is a digital SIM built into your phone. Instead of swapping a plastic card, you scan a QR code and a new data plan installs in seconds — your physical SIM stays in for calls and texts on your normal number.

Question 2

When should I install my eSIM?

Accepted Answer

Install it before you fly while you still have Wi-Fi. It won’t start counting data until you arrive and switch it on, so there’s no rush to activate — just install early and toggle it on when you land.

Question 3

Will I keep my phone number?

Accepted Answer

Yes. Zwitchy eSIMs are data-only, so your primary number stays active for calls and texts. Use the eSIM for internet and keep using iMessage, WhatsApp and your bank’s SMS codes as normal.

Question 4

What happens if I run out of data?

Accepted Answer

You’ll get a notification at 80% and 100%. Topping up takes two taps in the app and applies instantly — no need to install anything new.

Question 5

Can I use one plan in multiple countries?

Accepted Answer

Yes — our regional and global plans cover groups of countries on a single eSIM, so you don’t reinstall at every border. Single-country plans are cheaper if you’re staying put.

Question 6

How do refunds work?

Accepted Answer

If your eSIM won’t activate and our team can’t fix it, we refund unused plans within 30 days. Plans that have already started using data aren’t refundable, but we’ll always try to make it right.
