iPhone not reconnecting to mobile signal

[Gren]

My wife's just started a new job and her office has no mobile signal unless you're on EE. At the moment she's with Vodafone.

I'd expect when she leaves the office that her iPhone would pick up a data signal as soon as possible. It doesn't and has no data connectivity until she gets home and picks up our wifi. Calls work fine. If she then switches off wifi on her phone it will not reconnect to mobile data. Switching on and off mobile data does not work. Switching on and off airplane mode does not work. The only thing that works is a reboot.

Is there something we're missing in the settings? She's no tech wizard and I've only ever had Android phones. It's an iPhone 8 with whatever the latest version of iOS is.

Will check with data roaming on Tuesday. WiFi calling apparently needs to be applied by Vodafone

Thanks

I have it with Vodafone but can’t remember if it needs enabling.
