Hi I was  wondering if anyone can help, I have a LTE 4G WiFi modem and it will not connect to internet it just says connected no Internet even though I have set up the APN, I have tried factory reseting it and then setting it up again but it still gives the same message, the Sim works fine in my phone, I have tried it in adifferent modem with the same result connected no internet.

@gforan52  Is it definitely a  model compatible with UK networks?

Where did you get it? What make and model is it? An APN isn’t needed when using SMARTY in the UK. You can enter mickeymouse as the APN and data would work just fine!
