If you don’t have a mobile phone you can still use Rightmove Plus but you will be limited to using the parts of Rightmove Plus that don’t contain personal data.

If you don't have a work mobile phone but have a personal mobile phone and your own Rightmove Plus account, you can use your own phone to receive your one-time passcodes. It doesn’t cost you anything and your phone number is not used for anything other than security messages.
