eSim Czechia - From €3.36

Your eSIM connects to Prosím and T-Mobile — that's 2 operators giving you the widest possible coverage across Czechia. Your phone automatically locks onto whichever network has the strongest signal at your location. If 5G is available from any of these operators, your device will use it. Otherwise, you'll get 4G/LTE speeds.

Plans start at $3.36 for 1GB over 7 days. Unlimited data starts at $9.66 for 3 day(s). We have 14 plans total for Czechia, and every price is a one-time prepaid payment — no auto-renewal, no hidden fees, no roaming surcharges. Pay with card, PayPal, Apple Pay, or cryptocurrency (Bitcoin, USDT, ETH) with zero extra charges.

Our most popular plan for Czechia is 20GB for 30 days at $19.20 — it covers most trips with plenty of data for navigation, messaging, social media, and video calls. Traveling for just a few days? The 1GB / 7-day plan at $3.36 keeps costs down. Heavy data user or working remotely? Go unlimited starting at $9.66.

Three steps: (1) Buy your Czechia plan on Bitcall and receive a QR code instantly via email. (2) Scan the QR code in your phone's settings while connected to WiFi — you can do this at home before your trip. (3) When you arrive in Czechia, turn off airplane mode. Your eSIM connects to Prosím and T-Mobile automatically. The data validity period only starts counting from the moment you first connect in Czechia, not from when you buy it.

Yes. The Bitcall eSIM runs alongside your existing SIM using your phone's dual-SIM capability. Your home number stays active for incoming calls, SMS, and two-factor authentication codes. The eSIM handles your mobile data in Czechia through Prosím and T-Mobile. You do not need to remove your physical SIM — both work at the same time.

You can buy a top-up or a new plan directly from the Bitcall dashboard — it takes about 30 seconds and works from anywhere with an internet connection (use WiFi if your data is finished). The new data activates immediately. There is no limit on how many times you can top up. If you think you might run low, consider starting with the 20GB / 30-day plan at $19.20 for a comfortable margin.

If your phone was released after 2018 and supports eSIM, it will work in Czechia. This includes iPhone XS and all later models, Samsung Galaxy S20 and later, Google Pixel 3 and later, and most recent devices from Huawei, Xiaomi, Motorola, and OnePlus. Your phone must also be carrier-unlocked. The Czechia networks (Prosím and T-Mobile) use standard frequencies that work with any unlocked eSIM-compatible phone sold globally.
