Hi @Matthew_78759 & welcome to 3Community. I'm sorry for any confusion caused by your earlier conversations. Maybe I can make it clearer: hotspot is a phone feature and not a network feature. This means we can't promise you that it will work. Once we've confirmed that your mobile data is working, we'd direct you to the manufacturer because we do not have any access to alter phone features.
Are you having issues with your data? Are you able to access your apps or use Google? If you're having trouble this is something we can help with, and I'd be happy to investigate it for you. But if you're not having issues connecting to the internet and the only difficulty you're experiencing is related to your hotspot, I'd have to direct you to the phone manufacturer. If you have any questions, let me know.
If you think of the hotspot as an app on your phone, network operators dont support apps, so if there is an issue with an app its not up to them to resolve it, as its usually down to the phone manufactures to resolve issue
