Germany 4G/5G mobile proxies

Which mobile networks can I use in Germany?

Mobile IPs in Germany come from SIM cards on Telekom, Vodafone, O2, 1&1. Germany has four mobile network operators: Telekom, Vodafone, O2 and 1&1. BNetzA counted 225.9 million registered SIM profiles in Q2 2026, M2M included. 1&1 started its own network in December 2023 and had 14.8 million SIMs by Q2 2026.

Well-known brands and MVNOs that run on these networks include congstar (Telekom), Blau (O2), otelo (Vodafone), ALDI TALK, freenet. 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 Germany mobile proxies used for?

Teams use German IPs to check local results on google.de, prices on Amazon.de, Otto and Idealo, and ad placement on German publishers. City-level IPs in Berlin or Munich help test local map and store results.

With a mobile IP in Germany, teams typically:

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

How do I change the IP of a Germany 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.

Is it legal to use mobile proxies in Germany?

Using a proxy is legal in Germany; what matters is what you do through it. For scraping, the GDPR, BDSG and TDDDG apply, supervised by the BfDI and state DPAs; § 202a StGB penalises bypassing access protection.

PontProxy blocks online banking, government portals, payment processors and outgoing email (SMTP ports 25, 465 and 587), and every account follows our Acceptable Use Policy. Mobile ports are not for SMS verification, account farming or ban evasion.
