Can I get a free UK phone number?
Yes, for 14 days. The Free Trial includes one UK geographic (01/02) number allocated at random, with free voicemail-to-email and call divert. Paid plans let you choose your number.
Is the free number a real landline?
It is a virtual landline: a real UK geographic number delivered over the internet, so it works like a landline on any device but needs no copper line or line rental, and it already survives the 2027 PSTN switch-off.
