Why Choose a 03 Magic Number?
A Free Magic Number is a much better starting point than old-style 0845 or 0870 numbers. Here is how they stack up:
Free Starter Number
Get a UK 0845 or 0870 number without paying for the number itself.
Smart Call Routing
Send calls to the app, voicemail, forwarding, Receptionist or AI.
Receptionist Ready
Create greetings, menus and call flows from your phone.
Speech Credits
Use included credits to create voice prompts and welcome messages.
Business Friendly
Use it for enquiries, bookings, support, callbacks or campaigns.
Clear Call Costs
0845 and 0870 caller charges can vary by provider, plan and location.
0845 and 0870 numbers may cost callers more than standard UK 01, 02 or 03 numbers. Caller charges are set by the caller’s phone provider plus the applicable service charge. Reachability outside the UK may vary.
