Pay as You Go Sim Card not working with 4G LTE Dongle (Huawei E3372h)

I recently bought an O2 Pay as you go Sim and added an Internet Bundle for £10 where I get 7GB of data for a month. I know this has been activated as I've tested the 4G connection on my phone and it works. However, when I insert the sim into a 4G USB Dongle (the Huawei E3372h - https://www.amazon.co.uk/E3372h-320-Unlocked-network-Genuine-Warranty-White/dp/B085RDTZMP/ref=sr_1_5...) , the light flashes cyan rather than a solid cyan. This means it has established a 4G connection but won't establish an Internet Connection. I know the dongle works fine with other sim cards however, I can't work out why it doesn't work with this one. Do I need to activate something else so the o2 sim card will work inside a USB dongle.

It may not be picking up the settings for the o2 sim card. 

You will need to set the APN in the Control Panel for the Huawei Dongle - mobile.o2.co.uk  or try payandgo.o2.co.uk and then try to connect

You can't use a phone sim in a dongle.

It must be a data only sim.
