Change cellphone number

[Sealights]

Hello, 

I'm a old vodafone customer and I bought a new Iphone that comes with a Esim. How can I change it to my previous vodafone cellphone number?

Thank you

Hi @Sealights,

Within VF it isn't possible to transfer a mobile phone number to an already exist CallYa mobile phone number.
