AI Receptionist for Tradesmen: Put It on Your Own Mobile Number

Set your mobile to forward calls to the number your AI receptionist gives you when you are busy, do not answer or have no signal, then test it. Costs start at nothing (Smith.ai's free plan covers 25 calls a month); PN Receptionist is GBP 29 or 39 a month, and dollar-priced plans run from about $29 to $150.

Two things decide whether it works. Your carrier decides which forwarding conditions your phone offers, and the iPhone's own menu may show only "forward all calls", so conditional forwarding can mean dial codes. And your own voicemail must not answer first, or the receptionist never gets the call. The rest is a greeting, a short list of people who skip it, and a handful of test calls.

Four kinds of forwarding and the two or three to switch on

Forwarding is not one setting. Phones offer four, and picking the wrong one is the commonest reason a set-up "does not work".

The three conditional types leave you in charge. The phone still rings first, and you can pick up. The receptionist gets only the calls you would have missed anyway. That is the whole point of putting it on your own number: your customers keep ringing the number on your van, and you decide each day how often to answer.

Setting it on an iPhone or an Android phone

The menus differ by phone and carrier, and the two routes below are the ones one vendor guide describes. Before you start, get the receptionist's number from the service and write it out in full, including any area or dialling code.

1. iPhone: Settings, then Phone, then Call Forwarding. This menu may offer only the unconditional "forward all calls" switch, depending on the carrier. If that is what you see, use the dial codes below instead.
2. Android: open the Phone app, tap the three-dot menu, then Settings, then Calling accounts (on some phones it is Supplementary services), then Call forwarding. Look for separate options labelled When busy, When unanswered and When unreachable, and enter the receptionist's number in each.
3. Dial codes: where the menu does not offer the conditions, the standard GSM codes work on many networks. Type one into the keypad as if it were a phone number, then press call, and wait for the confirmation message.

Two cautions. These are the standard codes, but carriers can differ: some use other prefixes, some network settings do not enable them, and an "invalid MMI code" or "connection problem" message means asking the carrier or your phone's help page. And some networks let you set the delay for the unanswered forward in five-second steps, written like *61*[number]*11*20# for 20 seconds, though some cap it at 30. If one form fails, try the number in international format, or the carrier's own instructions, which win over any guide.

When you are done, ring yourself from another phone three times: once while you are on a call, once leaving it to ring out, and once with flight mode on. If the receptionist answers each time, the forwards are live. The tests near the end cover the awkward cases.

Ring time and voicemail: make the forward win the race

Your carrier's voicemail is the competitor. Both it and the forward want to answer an unanswered call, and whichever fires first wins. One vendor guide says voicemail usually picks up at around 25 to 30 seconds, and suggests forwarding at about 15 seconds. The same guide's example is four rings, roughly 20 seconds.

A quick sum: the guide's figures imply about five seconds a ring, so 15 seconds is three rings, 20 is four, and 25 is five. That leaves you the following choice:

• 15 seconds gives the caller a quick answer and you only a short time to find the phone. Good for a van, where the phone is on a dashboard mount.
• 20 seconds suits most people who work with the phone in a pocket or a toolbag.
• 25 seconds or more risks voicemail answering first on some networks. Avoid it unless you have turned voicemail off.

The safest fix is to make sure voicemail cannot win: ask your carrier to disable voicemail, or to lengthen the time before it answers, so the forward always fires first. Check what the status code returns afterwards (*#61# on many networks shows the number and the delay). If you are not sure, a test is simple: leave a call to ring out, and see who picks up.

Keeping family, regulars and suppliers off the receptionist

A receptionist on your personal mobile will also answer your mother if you miss her call. Three ways to deal with that, in order of effort:

1. A skip list in the tool. Powered Now says specific numbers can be set to skip the PN Receptionist and ring your phone as normal. Ask any other vendor whether known numbers can bypass it before you sign up.
2. A word in the greeting. "If you're a friend, call me back on this number" is cheap but clumsy, and the receptionist still logs the call as a lead.
3. A second number. A business number on an eSIM or dual-SIM phone, if yours supports it, lets you forward everything on that line without touching your personal one.

Tell the people who matter what is happening. A one-person removals firm's regular customers, a landlord who sends work, and the merchant should each know that if you miss the call, an assistant will take a message and you will ring back the same day.

What it costs a one-person removals firm at 15, 30 and 60 calls

As of October 2026, here are the published prices for a one-person removals firm with calls averaging two and a half minutes, which is the one assumption that matters for the minute-based plans. Take 15 calls in a quiet month, 30 in a typical one and 60 in a busy one.

The arithmetic is simple, and the spread is what to notice. On Smith.ai Free the bill is $3 for every call after the 25th: 30 calls is 5 × $3 = $15, and 60 calls is 35 × $3 = $105. Its $150 Pro plan only becomes cheaper once you pass 75 calls a month, because 75 calls on the free plan is also $150. Dialzara's 150 minutes at 60 calls is 90 minutes over its allowance, so $29 + 90 × $0.48 = $72.20. Goodcall and Rosie are flat across the range.

PN Receptionist is priced in GBP only, so I have not converted it. Its product page shows GBP 29 a month for Speech and GBP 39 for Speech + Text, billed monthly with no set-up fee and cancel any time, and it lists unlimited calls on both plans. The pricing page agrees on 29 and 39, but the home page says from GBP 29.99, so confirm the figure at checkout. The pricing page also describes both tiers as add-ons to any Powered Now plan, billed with your subscription, while the product page never mentions needing one, so ask whether you must hold a plan. Powered Now's own plans start at GBP 28 a month billed monthly, or GBP 280 a year (about GBP 23 a month), before tax, and that would add to the true cost if a plan is required. "Unlimited" on a phone product deserves one more question in writing: whether any fair-use limit sits behind it.

ServiceM8 is the other GBP-priced route, and it works differently. Its phone page lists three tiers of ServiceM8 Phone: Connect at GBP 15 a month, Connect Plus at GBP 25 and Unlimited at GBP 119. Connect and Connect Plus include 500 call minutes, then GBP 0.03 a minute; Unlimited has no minute cap. The AI Phone Agent comes only with Connect Plus and Unlimited, and the page describes it in general terms, as an AI assistant that handles your business calls the way you set it up, without saying whether it books jobs, takes messages or transfers calls. Every tier lists call recording and transcription saved to the job card, after-hours routing, a ServiceM8 number and number porting, while forwarding from an existing mobile is not described. That makes it closer to the port-or-new-number route at the end of this tutorial than to a forward from your own phone. Powered Now and ServiceM8 are job apps first, so their phone and receptionist add-ons make most sense if you already use the app for quotes and invoices.

The plan fee is not the whole bill. Four more items belong in the sum:

• Your mobile plan. One vendor guide says forwarded calls likely use plan minutes. At 60 calls and 2.5 minutes each, that is 150 minutes of your allowance, if your plan counts forwarded legs.
• International charges. The same guide warns that forwarding to a number in another country can add up. Make sure the receptionist's number is local to you, not abroad. Dialzara's page, for instance, says its plans include a number from one country and that numbers from other countries are available on request.
• Texting add-ons. Dialzara texting is $19 a month plus $0.05 per AI message and a small carrier fee per text segment; PN's Speech + Text plan costs GBP 10 more than Speech.
• Your time. Roughly an hour for set-up and test calls, then ten minutes a week reading call summaries for the first month.

Whether any of this pays depends on one number: how many enquiries you currently lose. If one extra move a month at an illustrative $400 comes from a call the receptionist caught, every plan in the table above has paid for itself. What an AI receptionist costs tradespeople and when it pays and the cheapest AI receptionist for a one-person business go deeper on the economics.

Check the plan will take a forwarded personal number

This is a question to settle before you pay. Of the pages I read, three said plainly that you keep your existing number and forward calls to the service: Goodcall's, Jobber's (a dedicated number is required, and existing numbers can be forwarded to it) and PN Receptionist's. The pricing pages for Smith.ai, Dialzara and Rosie did not say either way. Dialzara's page links to number porting, which moves your number onto their service rather than forwarding it, and that is a bigger step. They may well accept a forwarded mobile, because forwarding is a standard phone feature, but ask the vendor in writing and run the free trial or free tier first.

Jobber adds one rule that matters on a personal mobile: the escalation contact must be a different number from your business number. If your mobile is the number the account knows as your business line, escalations need to go to a second number, such as a partner's phone or an office line, or you rely on text alerts. Smith.ai AI receptionist set-up, from forwarding to the first test call walks through one concrete case, and an AI answering service for a mobile where you keep your number is the broader version of this section.

A greeting that is honest in 15 seconds

The greeting has four jobs: say whose line it is, explain why a person did not answer, say it is an AI, and tell the caller what happens next. Under about 15 seconds is plenty (roughly 35 words). Three greetings suit a one-person removals firm, and a landscaping version shows how little changes between trades:

SHORT
"Hello, [Name] removals. I'm out on a move, so I'm the AI assistant. Calls
may be recorded. I can take your details for a quote. What's the move?"

WITH AN URGENT ROUTE
"Hello, [Name] removals. I'm on a job, so I'm the AI assistant. Calls may be
recorded. If it's urgent, say 'urgent' and I'll text [Name] straight away.
Otherwise, how can I help?"

LANDSCAPING VERSION
"Hello, [Business] gardens. [Name] is on a job, so I'm the AI assistant. Calls
may be recorded. What's the work, and where is the garden?"

TEXT TO REGULARS BEFORE YOU SWITCH ON
"Hi [first name], from [date], if I can't pick up, an AI assistant on my
usual number will take your details and I'll call you back the same day.
If it's urgent, tell it 'urgent'. Thanks, [Name]."

Notice what the greeting leaves out: a list of services, opening hours and a company history. The receptionist can answer those if asked. And the removals questions it asks next are the ones you would ask on a first call: collection address and delivery address, the date, the number of bedrooms or the size of load, access (stairs, lift, parking) and whether packing is needed. Test two versions for a fortnight and keep the one that gets more usable details.

Recording and telling callers it is an AI

Most receptionist tools record calls and keep a transcript and a summary. Smith.ai's free plan lists recording, transcription and summaries, PN Receptionist shows each call's recording and summary in one place, and Jobber puts a recording and transcript in each conversation's details. I could not find a retention period on the Smith.ai or PN pages, so ask each vendor where recordings are stored and for how long, and whether you can delete them. Goodcall's pricing page shows the kind of answer to get: it keeps call history for 30 days on Starter, 90 days on Growth and without limit on Scale.

The legal side differs by place, and I cannot give legal advice here. In some places only one party needs to know a call is being recorded, in others everyone on the call must agree, and data-protection law may expect you to say what you do with a recording and for how long. Some places also expect callers to be told when they are dealing with an AI system, and saying so in your greeting costs a few words. Jobber's help article encourages owners to tell callers that the phone is answered by AI or that calls may be recorded, though it says neither is required, and it tells owners to check the recording rules that apply to them.

The practical rule is the same everywhere: say it at the start of every call, as the greetings above do, and ask your data-protection adviser before you switch on recording if you are unsure. Numbers, recording and data-protection checks for a small business receptionist covers the topic in more depth.

Seven test calls, including the one that loops

Do all seven before you tell customers, and repeat the first three after any change to your phone plan.

Test five deserves a word. If your mobile forwards unanswered calls to the receptionist, and the receptionist then transfers a call to your mobile while you are busy, your own forward can send that transferred call straight back. The caller ends up back with the receptionist, and you never get the call. It can happen because forwarding rules do not remember that a call has already been through the receptionist. The cures are a transfer target that is not your own mobile (a second number), a text alert in place of a live transfer, or a bypass for the receptionist's number if your carrier allows one.

Reading the first week's summaries on a removals line

Test calls prove the forwards work. The first week of real calls shows whether the receptionist asks what a removals quote needs. Read every summary that week, and the transcript for any that look thin. An illustrative first-week summary:

Call answered by AI assistant, Tuesday 11:42
Caller: [first name], [number]
Reason: quote for a house move
Moving from: two-bedroom flat, second floor
Moving to: [address]
Date: "next Friday, or the one after"
Packing: not discussed
Access: not discussed
Next step: [Name] to call back with a price

Three things need fixing, and none of them is the receptionist's fault. "Next Friday, or the one after" is not a date, so add a rule that it reads a calendar date back ("that's Friday the [date], is that right?") and records the date rather than the phrase. Packing and access were never asked, because the instructions said only "take details for a quote", so make them required questions; on a second-floor flat, whether there is a lift changes the crew size and the price. And check the caller's number: it should be the customer's, not yours. If summaries show your own mobile number instead, the forwarded calls are not passing the caller's number through, and every callback would ring you. Raise that with the vendor and your carrier before you tell a single customer.

Then count three things for the week: calls the receptionist took, calls that reached your voicemail instead, and summaries you had to complete by ringing back for missing details. Calls reaching voicemail mean the ring time is still too long for your network. Ring-backs for missing details mean the question list needs another line. When both are down to one a week or none, the set-up is doing its job and you can move from reading every summary to a weekly skim.

When forwarding stops being the right set-up

Forwarding is the cheapest way to start, and it has limits. Move away from it if you pass 75 to 100 calls a month, because pay-per-call plans stop being cheap. Move away if you want the receptionist to book into a calendar and text customers from a number that is clearly yours. And move away if your carrier cannot do conditional forwarding at all.

The alternatives are to port your mobile number into a cloud phone service, or to give customers a new business number. Quo's page, for example, lists one new or ported number per user on all seat plans (Starter $19 a month monthly, $15 billed annually), with an AI agent whose first 10 calls a month are free, then $25 for 40 calls; call transfers are listed only from the Business seat ($33 a month monthly). Porting changes how your number works for good, so read what it costs to switch business phone systems before you decide. For most one-person trades, a month on the free tier with conditional forwarding tells you whether the calls are worth a plan.

Questions about using your own mobile number

Can I switch the receptionist off when I am free?

With conditional forwarding you rarely need to, because it only fires when you are busy, do not answer or have no signal. If you want it fully off, cancel the forwards with the codes (##004# cancels all conditional forwards on many networks) or use the tool's own controls. Jobber has an on-off toggle for calls and texts on its Receptionist dashboard, and PN Receptionist lets you set weekly hours for when it answers.

Do I need a second SIM or phone?

No. The forwarding runs from your existing SIM. A second number, on an eSIM or dual-SIM phone if yours supports it, becomes worth considering if you want to forward every call without catching family calls, or if you want a separate business line. It is a convenience, not a requirement.

Does it work if my phone is switched off?

On most networks a phone that is switched off or out of coverage counts as unreachable, so the unreachable forward catches it. Set that condition as well as busy and unanswered, then test with flight mode on. A carrier that cannot forward on unreachable is worth knowing about before you rely on it.

Should I tell my existing customers?

Yes, with one short text before you switch on. Regulars who suddenly hear an AI voice may hang up, whereas a heads-up that an assistant will take their details and you will ring back keeps them calling. Sample wording is in the greeting section.
