Virtual number vs a second SIM
// the short answer
A second SIM gives you a separate mobile number but needs a dual-SIM phone or a second handset, and offers no business call handling. A virtual number rings your existing phone, keeps your personal number private, and adds business hours, recording, voicemail-to-email and a receptionist — usually the better choice for a business line.
When you want to separate work calls from personal, the two obvious options are a second SIM or a virtual number. They solve the problem very differently.

Frequently asked questions
Is a virtual number better than a second SIM for business?
For most businesses, yes. A second SIM only gives you another mobile number and needs a dual-SIM phone or second handset. A virtual number rings your existing phone, adds business hours, recording and voicemail-to-email, and can present a professional local, 0800 or 03 number — without carrying two devices.
Can a virtual number keep my personal number private?
Yes. Customers only ever see and dial your virtual number; it forwards to your personal mobile in the background, so your private number is never handed out.
Do I need a special phone for a virtual number?
No. A virtual number works with the phone you already have — calls simply forward to it. There’s no dual-SIM requirement and no second handset to carry.
What can a virtual number do that a second SIM can’t?
Set business opening hours, ring several phones in order or at once, record calls, send voicemail to your email, add a virtual receptionist, and give you a local or freephone number — none of which a plain second SIM offers.
