Can I Keep My Existing Phone Number With an AI Receptionist?
TL;DR
Calls: yes, fully. Your customers dial your existing number as normal. When you're unavailable, calls forward silently to your AI receptionist — no number porting, no disruption.
Texts & WhatsApp: not automatically. Standard call forwarding doesn't carry SMS — text messages stay on your original number. For incoming texts and WhatsApp, you'll use your dedicated Always In number (which we provide). We cover both in detail below.
This is one of the most common questions we get at Always In. And it's a fair one — your business number is your telephone identity. Customers have it saved, it's on your van, your invoices, your Google Business profile. The last thing you want is to change it.
The good news: you don't have to.
How It Actually Works
When we set you up with an AI receptionist, we give you a dedicated Always In number. You don't give this number to your customers. Your customers keep calling your existing number — your mobile, your landline, whatever you've always used.
The forwarding happens silently in the background. Here's the flow:
Customer dials your number
Same number as always — your mobile, 01xxx landline, whatever's on your website and van.
Your phone rings first
If you're available, pick up as normal. The AI receptionist never gets involved.
If you don't answer or you're busy…
The call is forwarded automatically to your Always In number. Your AI receptionist picks up — instantly, every time.
You get a notification
A push notification and text summary lands in your dashboard — who called, what they wanted, whether they booked, and any contact details collected.
Setting Up Call Forwarding
This is a one-time setup on your phone — takes about two minutes. The exact steps depend on whether you're using a mobile or a landline.
On a UK Mobile (EE, O2, Vodafone, Three)
Most UK networks use the same standard codes. You'll typically set up two conditions:
Divert when unanswered (no answer after ~20 seconds):
**61*[Your Always In Number]#
Divert when busy (you're already on a call):
**67*[Your Always In Number]#
Replace [Your Always In Number] with the dedicated number we provide. We'll send this to you in your welcome email.
On a BT or VOIP Landline
BT landlines use a similar "Call Diversion" service. Log into your BT account or call BT to activate "divert on no reply" and "divert on busy." Your engineer during onboarding will walk you through the exact steps for your specific provider.
What About Text Messages?
Here's where it gets a bit more nuanced — and it's worth being upfront about.
Call forwarding works flawlessly for voice calls. SMS (text messages) are a different story. Standard UK mobile forwarding doesn't route text messages — they stay on your original number.
For incoming SMS and WhatsApp enquiries, there are a few approaches:
- Use your Always In number for new customer SMS — add it to your website contact page as a "text or WhatsApp" option. Existing customers who already have your mobile can still text it as normal.
- WhatsApp messages — your dedicated Always In number is WhatsApp-enabled out of the box. Any customer who messages you via WhatsApp comes straight into your unified inbox alongside calls, Facebook, and Instagram messages. No extra setup needed.
- Virtual landline providers — if your existing number is a virtual/VoIP number (commonly used by businesses using services like Vonage or RingCentral), SMS forwarding is often available through your provider's settings.
💡 Pro Tip
The easiest long-term solution: keep your mobile for personal calls, put the Always In number on all future marketing materials (van wrap, website, business cards). Most established customers will still call your mobile — and the AI receptionist catches those when you're busy. New customers go straight to the AI number. Best of both worlds.
Will Customers Know the Difference?
When a call is forwarded to your AI receptionist, the customer experience is seamless. They don't hear a hold tone or a transfer announcement — the AI answers as your business, using your business name and a UK-accented voice.
A typical greeting sounds like: "Hi, thanks for calling [Your Business Name]. I'm the virtual assistant — happy to help. Are you looking to book an appointment, or do you have a question about our services?"
Most callers don't notice a difference, particularly for routine enquiries.
Common Questions
Do I need to change anything on my website or van?
No. Customers call your existing number, just as they always have. The forwarding happens behind the scenes.
What if I want to answer a call myself?
Just pick up. If you answer before the forwarding kicks in (typically after 4–5 rings), the AI never gets involved. If you're mid-job and can't answer, the AI handles it for you.
Can I turn forwarding on and off?
Yes. You can pause call forwarding from your phone's settings at any time — for example, if you're in the office for a week and want to handle all calls personally. Most networks let you toggle this with a quick dial code.
Does call forwarding cost extra with my network?
This varies by network and plan. Most UK business mobile plans include standard call forwarding at no extra cost. Personal SIM-only plans may have forwarding charges — check with your provider. We'll flag this during your onboarding call if it's likely to apply to you.
I have two business numbers — can both forward to the AI?
Yes. If you have multiple numbers (e.g., a mobile and a landline), both can be set to forward to the same Always In number. The AI handles them all from a single dashboard.
