“I've now read on this thread that we are not allowed to tether (Oops). Is this important? We did it without realising that we shouldn't / couldn't. Does it matter? Do they know when you tether? How do they stop it if they don't like it? I never realised that we were not allowed to tether. I'd not given it any thought, beyond seeing that my wife's phone could be set to work as a hotspot for up to 8 devices, and that it's download speed was as good as the Huawei mobile hotspot, so it seemed like a good idea (and I wouldn't be limited to just 5 GB as was the case with the Huawei kit).”
If it worked and let you do it, then I wouldn't lose any sleep over it its not like they can bill you for it on PAYG.
You were lucky that it did work however, normally once they detect it you will get a blocked screen appear with a message about tethering not being allowed and you won't be able to access anything until you go back to handset only, at least that is what I got when I tried it a few years ago.
Some people have randomly reported the same thing in the past, and found that they were able to tether, whilst others have found it blocked but I thought that they were fairly on top of detecting it these days, but clearly not in your case.
If it keeps working then great, but whilst it lasts just consider it a bonus which may disappear at any point in the future, if they do detect it / decide to block it
What type and model of phone was it...just out of interest
