Skip SFR roaming in Czech Republic
SFR customers travelling to Czech Republic typically pay around $614/GB on legacy roaming, or $8/day for a roaming pass. Silent eSIM is $1.08/GB — no expiry, no contract, no ID.
How to avoid SFR roaming fees in Czech Republic
- 01 Keep your SFR SIM active for calls and SMS 2FA at home.
- 02 Install Silent eSIM as a second line (every modern iPhone, Pixel, and Galaxy supports dual eSIM).
- 03 Land in Czech Republic, set Silent eSIM as the data line — pay $1.08/GB instead of $614.
- 04 Turn off "Data Roaming" on your SFR line so it never accidentally bills.
What SFR roaming actually costs in Czech Republic
Most SFR customers activate a day pass at $8/day when they land. For a 5-day trip that's $40 — before you've used a single GB. For a 7-day trip, $56.
Silent eSIM charges $1.08/GB with no daily fee and no expiry. A typical traveller uses 2–4 GB per week. At Silent eSIM rates, that's $2.16–$4.32 for the whole trip — compared to $56 on a SFR day pass.
You don't have to cancel SFR
Silent eSIM runs alongside your SFR SIM as a second line. Every modern iPhone (XS and later), Google Pixel (3 and later), and Samsung Galaxy (S20 and later) supports dual SIM. Keep SFR active for calls, SMS, and two-factor authentication. Set Silent eSIM as the data line the moment you land in Czech Republic. Turn off SFR data roaming so it never accidentally bills you.
When you leave Czech Republic, your Silent eSIM balance doesn't disappear — it carries to your next trip to any of 200+ countries. Load it once, use it for years.
