Before you go
Travelling in Czech Republic
How much data do you need in Czech Republic?
Maps, messaging, ride apps and a few photos use about 300 to 500 MB a day, so 1 GB covers a short stay and 3 to 5 GB a week of normal use. The smallest plan is 1 GB · 7 days for $1.57; a longer trip is cheaper per gigabyte on a bigger plan. For video calls, streaming or a hotspot for a laptop, unlimited daily data starts at $1.49 a day. Most plans top up from your order page if you run low.
eSIM or a local SIM card in Czech Republic?
A local SIM card in Czech Republic usually means a shop or an airport counter, a passport for registration and a swap of your home SIM. An eSIM is installed on Wi-Fi before you fly, keeps your home number for calls and texts, and is working as the plane lands.

Need broader coverage?
These multi-country eSIMs include Czech Republic and keep working when you cross a border.
Why an eSIM
Why use an eSIM in Czech Republic?
Landing in Czech Republic with data already working means maps, translation and your ride from the airport are ready before you reach the exit. No kiosk, no passport photocopy, no hunting for Wi-Fi.
Your home SIM stays in the phone for calls and texts. The eSIM handles data on local networks, so you avoid roaming bills without losing your number.
Install on Wi-Fi at home and keep the line switched off until you land. Validity starts the first time it connects abroad, not when you buy.

How much does an eSIM for Czech Republic cost?
Plans start at $1.49; a data plan costs from $1.57 for 1 GB · 7 days. Unlimited daily data costs $1.49 a day (the first 1 GB each day at high speed, then 512 Kbps under the fair use policy). Prices are in US dollars and include everything: no roaming fees, no subscription.
When does my Czech Republic plan start?
On nearly every plan, the first time the eSIM connects to a network abroad, not when you buy or install it. A few plans start on installation; each plan says which. Install within 180 days of purchase.
Do I need to change any settings?
Turn the travel line on, enable data roaming for that line only, and set it as your mobile data line. Keep data roaming off on your home line. Most phones set the APN automatically. If you are connected but have no data, enter the APN shown on your order page or eSIM page (none shown means the phone sets it itself), or reply to your order email and we will help.
How fast is it?
Each Czech Republic plan lists its operators and whether they run 3G, 4G or 5G; each plan card shows its best generation. Daily unlimited plans slow to the fair-use speed shown on the plan once the day's full-speed data is used.
Can I top up or buy again?
Most plans can be topped up from your order page, with more data for the same area or more days. Plans marked non-reloadable cannot; buy a new one and it installs the same way.
Is tethering allowed?
Yes, personal hotspot works on every plan.
