Tenants don't have UK phone number for Tenant Referencing check

I want to use openrent tenant referencing to check a tenant from an European country. She got a job offer and will start working in the UK. She does not have a UK phone number which the Openrent Tenant referencing form requires.

What should I do?

Put yours in? If you want rent insurance this could be a problem. I think its only needed to keep them updated via text and to chase them up.

no, they need to live in the uk for 6 months at least for credit check.

I decided to skip the Tenant Referencing and take the risk. The tenant showed me her job offer.
