Czechia 4G/5G mobile proxies

Which mobile networks can I use in Czechia?

Mobile IPs in Czechia come from SIM cards on T-Mobile, O2, Vodafone. The Czech Republic has three MNOs: T-Mobile, O2 and Vodafone. T-Mobile reported 6.63 million customers in Q1 2026; Vodafone reported 4.18 million for April to June 2026.

Well-known brands and MVNOs that run on these networks include Kaktus, Tesco Mobile, SAZKAmobil. A mobile IP from any of them belongs to the address ranges of its host network.

Why do websites trust mobile IPs?

Mobile networks share a small pool of public IPv4 addresses between many subscribers through carrier-grade NAT (CGNAT, RFC 6598). One mobile IP can therefore carry traffic from many real phones at once.

Websites know this, so they rarely block a mobile IP outright. This is a mechanism, not a guarantee: behaviour that breaks a site's rules still gets flagged. Learn how to check an exit IP in our ASN lookup guide.

What are Czechia mobile proxies used for?

Czech IPs show local results on Google and on Seznam.cz, plus local prices on Alza.cz and Heureka.cz. They also help QA Czech-language apps and ads.

With a mobile IP in Czechia, teams typically:

• test apps and mobile checkouts as customers on T-Mobile, O2 see them;
• verify mobile ads and app-install campaigns shown in Czechia;
• track mobile search results on google.cz;
• manage brand and client social media accounts from a stable local IP.

How do I change the IP of a Czechia mobile port?

Each dedicated port has its own rotation link. Call it and the modem reconnects to the carrier, which usually assigns a new IP within seconds:

Replace {port} with your port number and API_KEY with your key from the client area. You can also set an automatic rotation timer. Connection details for HTTP and SOCKS5 are in the quickstart guide.
