Guernsey 4G/5G mobile proxies

Which mobile networks can I use in Guernsey?

Mobile IPs in Guernsey come from SIM cards on Sure, JT. Guernsey has two mobile network operators: Sure and JT. Sure bought Airtel-Vodafone in November 2024 and moved Airtel accounts to its own systems in September 2025.

Well-known brands and MVNOs that run on these networks include Coop Mobile (Sure). 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 Guernsey mobile proxies used for?

Guernsey is outside the UK VAT area, so UK retailers may treat GY postcodes differently at checkout. Guernsey IPs help verify those local views and ads on publishers such as the Guernsey Press.

With a mobile IP in Guernsey, teams typically:

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

How do I change the IP of a Guernsey 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 Guernsey?

Using a proxy is legal in Guernsey; what matters is what you do through it. Guernsey applies the Data Protection (Bailiwick of Guernsey) Law, 2017, supervised by the Office of the Data Protection Authority.

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.
