ISP Reviews by ThreeUKequals RyanAir

Sold a 500Mbps service, very close to tower. Yes, accepted that under normal loads it would probably be half that, which it was, initially.

Until a FIVE DAY complete system outage. The 4G 'fallback' was pointless as this was overloaded. It was just about possible to send/receive text emails. 4G/5G cellular was also down so as we stupidly have Three cellular we had zero comms. This was not in the countryside, but a major urban area.

Next issue was that all remote access to anything requiring SSL authentication stopped working - so no access to NAS, security cameras, UniFi network controllers etc. Could not log in to secure work email. Three had blocked a critical MTPP port rendering any such SSL access broken. This took TWO WEEKS to resolve.

Let's be clear at this point that the Indian call centre support is beyond hopeless: it is simply a Level 1 box-ticking idiot test. Everything ends up at 'factory reset the modem' (which has NOTHING to do with ANY of the issues), and then when they manifestly fail to solve anything, you are referred to "Customer relations" whose ONLY offer is not escalation, but to give you a free contract termination.

Now the 500Mbps service drops EVERY DAY between 5-10pm to around 50Mbps. Either it's been grossly oversold, or possibly yet another technical snafu. No resolution in sight.

I have had endless problems with Three 5G Broadband.

It is cheap but utterly useless, and should you have any issues you have to deal with the most inept, useless, automaton-centric overseas call centre imaginable.

Firstly, we have endured several multi-day complete blackouts due to mast failures, system upgrades that failed and so on. Sadly we have There mobiles o that meant we are 100% cut off completely. This is in a 100,000 person conurbation, in 2025. Well and 2024.

Secondly, endless technical issues . The latest is that all business email has gone down. Secure authentication is no longer possible (so we cannot log in at all even though we are on a mobile device). All remote access to security systems has fallen over - so no camera access, no door entry system access, and no access to NAS. And on top of that our UniFi Console is unreachable from outside or via UniFi cloud.

Three 5G broadband has broken all services, TWELVE phone calls over a week. TEN HOURS onto support - who are mindless script-reading numpties. And no resolution. They various argue that they Not blocking ports, that yes they were but have unblocked, it's IPv6 , no it's turned off, and so it goes on.

Anyone with half a brain can see that they are in fact interfering with OUTBOUND MQTT over port 8883. Two hours with UniFi support confirmed that.
