Czech Republic eSIM — FAQ

How do I get an eSIM for Czech Republic?

Pick a Czech Republic data plan below, pay by card or crypto, and we deliver your eSIM instantly. Scan the QR code and you're connected in minutes — no physical SIM, no store visit.

Will my phone work with a Czech Republic eSIM?

Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3+, and recent Samsung Galaxy S/Z models. Your phone must be carrier-unlocked.

Does the Czech Republic eSIM include 5G?

Yes — our Czech Republic plans connect to 5G where the local network supports it, and fall back to 4G/LTE automatically.

Can I keep my own phone number?

Yes. The eSIM runs as a separate data line, so you keep your main number for calls and texts while using Czech Republic data on the eSIM.

When does my plan start?

Your validity begins when the eSIM first connects to a network in Czech Republic, so you can install it before you travel and it won't start counting down until you arrive.
