Luxembourg 4G/5G mobile proxies

Which mobile networks can I use in Luxembourg?

Mobile IPs in Luxembourg come from SIM cards on POST, Tango, Orange. Luxembourg has three main mobile networks: POST, Tango (Proximus Luxembourg) and Orange. ILR counted about 1.02 million mobile SIM cards in 2025. POST held 50.3%, Tango 32.9% and Orange 15.8%.

Well-known brands and MVNOs that run on these networks include the operators above. 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 Luxembourg mobile proxies used for?

Teams use Luxembourg IPs to check google.lu results, delivery and price options shown to Luxembourg addresses, and multilingual ads in French, German and Luxembourgish. Amazon has no Luxembourg store, so Amazon.fr and Amazon.de are often checked.

With a mobile IP in Luxembourg, teams typically:

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

How do I change the IP of a Luxembourg 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 Luxembourg?

Using a proxy is legal in Luxembourg; what matters is what you do through it. Scraping that touches personal data falls under the GDPR and the Law of 1 August 2018, supervised by the CNPD.

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.
