Hi @Izzo,
Thank you for coming back to me about this and advising about what checks you've completed.
Are you able to use 3G at all?
I was able to look into this issue further for you, and I can see that there has been a fault with the mast in your area. However, this issue was recently resolved, so your services should be back up and running soon.
Please reboot your device and turn your mobile data off and on again to see if this has helped.
Let us know how you get on.
Thank you.
