Mobile data glitchy

[KatCo]

For days I have been having issues with my mobile data. I have turned phone off and on. Reset network settings. And it still keeps happening. Sometimes it works for about 5 mins and then it doesnt work for hours after. I have an iphone 11. I have about 20GB data on there so it's not that. I use my mobile data when I am at uni to hotspot my ipad and I can't do my work or take part in activities because of this and it's annoying me. At one point, it changed my network settings to vodafone !!  Quick to take my money each month though. 

Does anyone know what I can do to get this working again?

Hello KatCo.

Thanks for your post. 
Sorry to hear about the issue with your Mobile connection.

Does this happen indoors and outdoors?

Is it in one location or several locations?

Does a complete reboot help at all?

Hi,

It happens where ever I am. Mostly indoors but goes glitchy outdoors too. Worked perfectly fine up until a few days ago. I have rebooted my phone but it still happens. 

Thanks

I don't have another device to be able to do that.

That's okay KatCo.

Can you please have a look at this handy link to run some tests on your handset.
