Why did Three start capping my 5G broadband speed?

[autopilot]

Is there any reason why a few months ago Three started to limit my speed to 120mbps? We use it as our main internet and are relatively heavy users (for a family anyway, sometimes up to 3tb per month). Used to get over 300mbps. I have tested day and night, for weeks, and 120 is the max. 

Confirmed it’s out account, as I have tried other 3 SIM’s and same APN, multiple routers (with cell and band locking). When I used a different thee SIM I get the full speed again.  

Is is because of heavy use, or some other reason? Anyway to get this limit removed?

Hi @autopilot,

You shouldn't be running into limited speeds on Three Broadband, but we did recently identify some users were experiencing a 120mbps limit. In all other cases I'm aware of, a fix was rolled out a couple of weeks ago, and rebooting the router should have resolved this.

In case this is persisting, I've sent you a PM to ask for a bit more info.
