Peace by night.The Professional Second Number for UK Tradespeople
A dedicated business number on the phone you already carry. Hand it out on quotes, Checkatrade and van livery. When you down tools, switch it off — your personal line stays strictly personal.
Three problems, one line
Calls during Sunday dinner
Clients ringing at 9pm for quotes. Set opening hours and automated away replies on WhatsApp Business so enquiries get answered while you eat in peace.
Your personal number on a van
Don't plaster your personal mobile across signwriting, quotes, and Facebook. Put your SecondSim business number everywhere without compromising your family privacy.
Two phones in tool pockets
Stop carrying two bulky handsets on building sites or up ladders. SecondSim runs digitally alongside your personal SIM on one single phone.
“Clients used to call me at 10pm asking for quotes. Now my SecondSim auto-replies with my booking link after 6pm. I finally have my evenings back.”
Live before your next job.
Buy the plan, tap the install link, register WhatsApp Business. Sixty seconds, no paper forms, nothing in the post.

Do I need to buy a second phone to use this?+
No. SecondSim works as an eSIM alongside your existing SIM on your current iPhone or Android phone. Both lines stay active simultaneously, so you never need to carry two phones on building sites or up ladders.
Can I use this number on Checkatrade, MyBuilder, or van graphics?+
Yes. It is a genuine UK mobile number (+44 7...) that looks completely professional on van graphics, quotes, invoices, and trade directories like Checkatrade, TrustATrader, and MyBuilder.
What happens when I am off the clock in the evening?+
You can set opening hours and automated away replies on WhatsApp Business, or mute calls to your SecondSim line after hours, ensuring client enquiries are captured while your family evenings remain undisturbed.
Is this a real mobile number or a VoIP app?+
This is a 100% real, carrier-grade UK mobile number on Vodafone's Tier-1 network. It is NOT a VoIP or virtual number. It reliably sends and receives standard cellular calls and SMS, and passes bank and WhatsApp verifications natively.
Can I manage multiple numbers for apprentices or crew members?+
Yes. You can manage multiple team lines from your SecondSim account dashboard on one consolidated invoice. If a crew member moves on, you retain ownership of the number and can reassign it immediately.
