Equip your agents.
Protect your clients.
Instant UK business numbers for estate agents and letting managers. Deploy in 60 seconds to existing phones, keep client databases agency-owned, and consolidate all branch lines onto one monthly VAT invoice.
Three problems, one line
Departing agents walking with client lists
When agents leave, taking their personal phone means taking your vendors and buyers with them. Agency-owned SecondSim eSIMs stay with your firm and can be reassigned instantly.
£350 hardware costs per new hire
Stop buying secondary handsets that get dropped, lost, or left in desk drawers. SecondSim runs on your agents' existing smartphones with complete work/life isolation.
Dozens of messy expense claims
Chasing 15 different agents for reimbursable phone bills every month wastes valuable admin time. Consolidate your entire team onto a single monthly corporate invoice.
“When an agent moved to a competitor last year, they took half our vendor pipeline with them on their personal WhatsApp. Now all our negotiators use SecondSim. If anyone leaves, we reassign the number in two minutes.”
Equip your agency in minutes.
Add team members, email 1-click install links, and have your entire agency branch active on official business lines before today's viewings start.

How do I manage billing for multiple estate agents?+
SecondSim provides centralized billing. All your agents' lines are consolidated onto a single monthly corporate invoice with full VAT breakdown, eliminating individual employee expense claims.
What happens to the mobile number if an agent leaves the agency?+
Because your agency owns the numbers, you can instantly revoke the eSIM from a departing agent and reassign the number to a new hire in 60 seconds, keeping your client database and vendor relationships protected.
Do I need to buy secondary work phones for my team?+
No. SecondSim deploys real UK mobile numbers via eSIM directly to your agents' existing iPhones or Androids, creating a fully separate business line with zero hardware expense.
How fast can I onboard a new agent?+
Instantly. Add the team member in your dashboard and they will receive a 1-click installation link via email that activates their new business line in under 60 seconds.
Can agents separate personal calls from property inquiries?+
Yes. Modern iOS and Android devices clearly label incoming calls with the eSIM line name (e.g., 'Agency' or 'Viewings'). Agents can also run WhatsApp Business exclusively on the work number.
