Never at 2am.The Professional Second Number for UK Property Landlords
A dedicated UK mobile line for private landlords, HMO owners, and property investors. Publish your number on OpenRent, Rightmove, and tenancy agreements without sacrificing your personal evening peace.
Three problems, one line
Tenants calling your personal phone at 2am
A dripping radiator shouldn't interrupt family dinner or sleep. SecondSim lets you set business hours, mute evening calls, and provide automated emergency contractor contacts.
Portal spam from OpenRent & Gumtree ads
Putting your private mobile on public property ads invites cold calls from aggressive agents and marketers. Publish your SecondSim number and keep your personal phone private forever.
Maintenance photos lost in family WhatsApp
Digging through personal messages to find a gas safety cert or boiler photo is chaotic. Connect SecondSim to WhatsApp Business and organize chats neatly by property address.
“I manage four buy-to-let flats in Manchester. Handing tenants my personal number was the worst mistake I made — calls during dinner, texts on holiday. With SecondSim, tenant WhatsApp is separated and muting at 7pm is effortless.”
Live before your next tenancy.
Pick your plan, tap the 1-click install link, add your dedicated landlord line to listings and contracts. Sixty seconds, no contract, cancel anytime.
