Hi,

Check no carrier updates are pending.  Help link https://support.apple.com/en-gb/HT201270

On the iPhone hold down the Sleep/Wake Button and Home button together until the Apple Logo shows. Then On seeing this Apple Logo release both buttons ,and the iPhone will reset , which has been known to clear most glitches.

Try

Settings -> General-> Reset -> Reset All Settings.

To add.

Perhaps swap around SIM cards to see what happens. 

Options......

Contact customer servives on 191 or Live chat from a computer to check the account.

A Vodafone shop can perform a sim swap which moves the number and tariff to a new SIM card. 

A follow up option is ask an  store to check out the iPhone via a https://www.apple.com/uk/retail/geniusbar/ appointment if you have one local.

Can your mum's phone pick up 4G if you swap over your sims?
