eSIM data plans for Czech Republic

Plans for the Czech Republic come in two shapes: a set data allowance that lasts up to 30 days, or an unlimited allowance sold by the day. Both run on O2, and the fixed data plans also run on Vodafone.

Fixed data plans, sized to the trip

The smallest option, 1GB for 7 days, suits a short city break with light map and message use. The 5GB and 10GB plans give more room for maps, browsing, and sharing photos, and the 20GB and 50GB sizes suit longer visits or anyone working from their phone or laptop while away. Every fixed data plan can be used for hotspot and tethering, so a phone plan can share its connection with a laptop or tablet.

Running low mid-trip

If a fixed data plan's data is used up before the trip ends, the plan stops and a top-up on the same eSIM restores the allowance, so the original size is a starting point rather than a hard limit to plan around.

Unlimited by the day

The day plans run on O2 and suit travellers who would rather not track a gigabyte count at all, from a single day layover up to a full month at 30 days. They carry a fair use policy: past a daily amount, speed is reduced for the rest of that day, then returns to normal the next. Hotspot and tethering work on these plans too, which makes the longer day plans, like the 15 or 30 day options, a straightforward choice for someone who wants one flat rate covering both a phone and a laptop for the whole stay.

Buying ahead of the flight

An eSIM for the Czech Republic can be installed any time before departure at no cost, since the plan's validity only begins once it connects to a network in the country. That makes it simple to set everything up in advance and travel with the eSIM already installed and ready to switch on.
