Unlimited‑data eSIM options are available in the Czech Republic. Providers such as Firsty, Yoho Mobile, abesteSIM, Roamify, MicroEsim, Billion Connect, Truely, Yesim and FairPlay all offer plans that do not cap data usage. Many of these plans include tethering and use the 5G network, though a speed limit of 5 Mbps is applied to most of them; Firsty’s plan is the only one with a fixed lower limit of about 256 kbps, and all plans may be subject to throttling during peak usage.

The price range for unlimited data plans varies from free or very low prices (Firsty’s 1‑day plan is listed at $0.00) up to about $30 for longer‑validity offers such as FairPlay’s 3‑ to 30‑day plan at $29.69.

What are the major mobile networks available for a travel eSIM in Czech Republic?

In the Czech Republic, the primary Mobile Network Operators (MNOs) are:

O2 Czech Republic: A major integrated operator providing extensive mobile and fixed-line services, including 2G, 3G, 4G, and 5G networks.
T-Mobile Czech Republic: A subsidiary of Deutsche Telekom, offering comprehensive mobile services with widespread coverage across the country.
Vodafone Czech Republic: Part of the Vodafone Group, delivering a range of mobile services with a significant customer base and network reach.

In addition to these MNOs, the Czech Republic hosts several Mobile Virtual Network Operators (MVNOs) that provide mobile services by leasing access from the major carriers. Notable local MVNOs include SAZKAmobil and Lama mobile, both of which utilize Vodafone's network infrastructure. It's important to note that most travel eSIMs rely on MNO infrastructure rather than MVNOs.

Can I get a travel eSIM with a phone number and SMS for Czech Republic?

Yes, there are travel eSIMs that include a phone number and SMS support for the Czech Republic. The options come from several providers, such as Airalo, SimOptions, GlobaleSIM, Roamify, LinkeSIM, and MoreMins eSIM. Plans that give you a local Czech number use the +420 dialing code and are available through Airalo (O2 – 10 GB) and various SimOptions eSIMs, such as the Go Card and Holiday Zen packages. Other providers offer foreign numbers with dialing codes +1 (United States), +33 (France), and +44 (United Kingdom); for example, many Roamify and LinkeSIM plans use +33, while GlobaleSIM and some Roamify offerings use +1, and MoreMins eSIM supplies a +44 number.

The telephony features are consistent across these plans: voice calls can be both inbound and outbound, and SMS is either inbound only or inbound/outbound depending on the specific package. Prices for these eSIMs start around $4 for a 1 GB, 7‑day GlobaleSIM plan and rise to roughly $120 for larger data packages such as a 500 GB, 90‑day Roamify plan. Validities range from a few days to 180 days, giving travelers flexibility based on the length of their stay.
