O2 on our network
Virgin Media O2, large consumer base
O2 is part of Virgin Media O2, the joint venture of Liberty Global and Telefónica formed in 2021. It has one of the largest consumer subscriber bases in the UK, including many MVNO customers.
O2 is a good choice for consumer-facing tests where you want a mainstream UK mobile profile other than EE.
Network generation
Our O2 modems in the United Kingdom run on 4G (LTE). The address ranges are the same ones O2 subscribers use every day, and the throughput of a dedicated modem comfortably covers browser automation, scraping and QA workloads.
Carrier-grade NAT
Mobile operators have far more subscribers than public IPv4 addresses, so they place handsets behind carrier-grade NAT (CGNAT): hundreds or thousands of devices share each public address. Proxies on O2 exit through the same CGNAT gateways as O2's own subscribers, which is why target sites rarely block them — a block would hit their real customers too.
The flip side is that you do not own the address. Other O2 subscribers can appear behind the same IP at the same time, and the public address is assigned by O2, not by us.
How rotation behaves
Rotating a mobile proxy reconnects the modem's data session, and O2 assigns a new address from its pool. Expect a few seconds of interruption while the session re-establishes; open connections are closed. We enforce 10 seconds between two manual rotations of the same proxy.
Because the carrier chooses the new address, you can occasionally receive one you have seen before, especially after many rotations in a short period. Rotation can be triggered from the dashboard, the API or the rotation link, or scheduled every 2 to 60 minutes.

Are O2 proxies shared with other customers?
No. Each proxy is a dedicated modem with its own O2 SIM, used by you alone for the duration of the plan. The public IP sits behind O2's CGNAT, so ordinary O2 subscribers may share it — that is what makes the traffic look like theirs.
Can I move an existing proxy from O2 to another carrier?
No. The carrier is tied to the modem's SIM. Order a proxy on the other carrier, or choose "any carrier" at checkout when the network does not matter for your use.
How long does a rotation take on O2?
The modem reconnects and receives a new address from O2, usually within a few seconds. Manual rotations are limited to one every 10 seconds per proxy; scheduled rotation runs every 2 to 60 minutes.
Is bandwidth limited on O2 proxies?
No. Mobile proxies have unlimited bandwidth and we apply no traffic cap. Throughput depends on O2's radio conditions at the modem site.
How much does a proxy on O2 cost?
$10 for 24 hours, $43 for 7 days or $115 for 30 days per proxy — the same price for every carrier in the United Kingdom. 30-day plans get a volume discount from 5 proxies.

Start with 24 hours for $10. The carrier stays the same when you extend to 7 or 30 days.
