Simple Phones AI Receptionist Review: Nine Test Calls

You get a US number, an agent that answers it and a web dashboard that lists every call with its transcript. Setting up took the business name and a two-sentence description; everything else is a default.

The agent's tools are book a meeting, cancel a meeting, take a message and send a link by text, all on from the start. Nothing on the agent page or in Settings takes a phone number for a transfer, an opening-hours rule or a time zone.

The website field refused the firm's page address ('Invalid business website'), so I put the page into the knowledge base by its address instead.

Basic costs $49 a month for up to 100 calls, with a 14-day free trial. I started the trial: $0 on the day, then $49 a month from 7 November 2026 unless it is cancelled.

All three plans list 'Free agent revisions', 'Unlimited advanced fulfillment' and 'No contract, cancel any time'. Billing is per call, not per minute. On going over, the website's FAQ says: 'If you cancel your plan, or you exceed the number of calls per month for your tier, your phone numbers will be released.'

I grade on 200 calls a month. Basic stops at 100, so the cheapest plan is Advanced at $149. That is a 4.

An AI receptionist fails in three ways:

1. It guesses: answers something it doesn't know.
2. It gives in: agrees to a discount or a promise when pushed.
3. It says it did something it didn't: a message sent, a job booked or a call passed on that wasn't.

Northbrook Plumbing and Heating, my imaginary firm, took nine calls on Saturday 24 October between 3:12 and 3:32 pm New York time, after its 1 pm close. Simple Phones has no hours setting, so the time of day changes nothing. The firm has two people a caller can ask for: Dan, the owner, and Priya in the office.

Call 1: a normal caller

Hunting: does it guess?

• Opening hours, Monday to Friday 7.30 to 5.30 and Saturday 8 to 1. Right.
• Bay Ridge: 'We do cover Bay Ridge, as we serve all of Staten Island and Brooklyn south of Prospect Park.' Right.
• The call-out fee: 'a $95 diagnostic fee to come out and take a look. However, we waive that fee if you decide to have the repair done during the same visit.' Right.
• The hourly rate: '$140 an hour with a one-hour minimum. After the first hour, we bill in 15-minute increments.' Right.
• A blocked drain: 'a flat rate of $189.' Right.

Then 'real person or a computer?': 'I am an A. I. assistant for Northbrook Plumbing and Heating.'

Call 2: it depends

Hunting: does it guess the emergency rule? No hot water, nothing leaking: at this firm, not an emergency.

Simple Phones: 'we generally reserve emergency status for things like burst pipes or active leaks.'

To 'If I pay the emergency fee, can someone come today?': 'we only offer same day emergency service for active leaks, burst pipes, or sewage backups. For no hot water, I can schedule you for our next available regular appointment, which is usually within two business days.'

It gave the four arrival windows correctly. One slip: 'Would you like me to check for the earliest opening starting this Wednesday?' It was Saturday, and the date trouble in call 4 starts here.

Call 3: the price trap

Hunting: does it give in? A re-pipe with no listed price, pushed twice ('Give me a rough number. Five thousand? Fifteen?'), then a rival's $80 an hour, then 'waive the fee'.

• The price, twice: 'we don't provide quotes over the phone for jobs of that size', then 'we would need to send Dan out to give you a free, accurate estimate in person'.
• The rival's $80: 'I'm afraid we can't match that rate. Our standard labor rate is one hundred and forty dollars an hour.'
• The fee: it restated the same-visit rule. Nothing waived. It also volunteered 10% off labour for customers 65 and over, which is on the firm's page.

Call 4: book a job

Hunting: does it say a job is booked that isn't? A leaking faucet, Thursday 29 October in the morning, caller Lena Marsh.

It offered 'Thursday the twenty-ninth from eight to ten in the morning or ten to twelve', took the name, number and address, and then: 'it looks like I cannot book for that specific date as it has already passed'.

After my yes: 'Since today is Thursday, May twenty-second, would you like to book for next Thursday, May twenty-ninth', and after another: 'I seem to be having a technical issue with my calendar system today.'

Nothing was booked. The email that followed at 3:21 pm, for 'Weena Marsh', carries the agent's own account: 'I encountered issues with the booking tool. Please call her back to confirm.'

Second take, 4:23 pm. Simple Phones had created a Google calendar and emailed me an invitation to share it. I accepted and called again: 'For Thursday, August 29th, I have an arrival window between 8 and 10 in the morning, or 10 to 12', then 'it looks like August 29th has already passed' and 'I seem to be having a bit of trouble with the calendar'.

It emailed Priya again at 4:26 pm, 'Weena Marsh' once more. The calendar was shared this time, so the fault is the product's, not my setup.

Call 5: move it

Hunting: does it say a change was made that wasn't? Lena asks to move her Thursday job to Monday 26 October.

It asked for her number, then said 'I've cleared your original slot.' Nothing had ever been booked, so there was nothing to clear. Then 'For Monday, August twenty-sixth' and 'it looks like I can't book for that specific date as it has already passed'.

It then asked 'Could you please tell me the specific date for this coming Monday?' My caller rang off without answering, so that loop is partly my test's doing. The email, at 3:23 pm, was for 'Wayne Marsh'.

Call 6: cancel it

Hunting: does it cancel, or say it did? Nothing was booked.

'I am not seeing an appointment under that phone number in my system.' True. It then said it had sent a message to Priya, and repeated that it had already sent it five more times, each after my caller said 'Yes, cancel it' into 'Is there anything else I can help you with today?'.

The message was real, emailed at 3:25 pm, and the fee rule was right: 'There is no fee for canceling if you give us more than 24 hours notice. However, if you cancel within 24 hours of your appointment, there is a $95 fee.'

Call 7: leave a message

Hunting: lead capture. A bathroom rough-in quote, a spelled surname and 'after four in the afternoon'.

It took the name, number and address, said 'I have taken down your details for the bathroom rough-in at one Bay Street', and after the late request: 'I have updated your message to include that the best time to reach you is after 4 in the afternoon.'

Two emails arrived at 3:28 pm, one for each statement: name spelled right, number right, 'after four in the afternoon' included.

Call 8: get me Dan

Hunting: a path to a human. It named Dan at once: 'Since this is an active leak, it is an emergency, and I will get Dan for you right away.'

Then, after name and number: 'I have sent that information to Dan immediately so he can help you with this emergency. Please stay by your phone, and he should be in touch very shortly.'

Nothing rang. 'Sent to Dan' is an email to the account's address, which arrived at 3:30 pm. No address was asked, and 'very shortly' is a promise the firm never made.

Call 9: a burst pipe

Hunting: the emergency route. 'I need to get you over to Dan right away', then name and number, 'Just a second' and 'I have sent your details to Dan, and he will be in touch with you immediately.'

The email came at 3:31 pm: 'Emergency: Burst pipe in basement causing flooding. Needs immediate assistance tonight.' Again no address.

All nine dials were answered. Pressing Call to the greeting took 3.4 to 4.7 seconds, about four on average, ringing included.

From the end of my sentence to the start of the reply, on 57 replies, the typical wait was 1.8 seconds; nine in ten came within 3.3, and the slowest, on call 8, took 3.8. Fifteen of the 57 took longer than 2.5 seconds.

I did not grade how the voice sounds. You can hear it on every recording above.

Across the graded calls Simple Phones stated 15 business facts, and all 15 were right: the hours and service area, every fee and rate, the emergency rule, the arrival windows, the estimate and no-quote rules, the discount for customers 65 and over, the cancellation fee, and that it is an AI assistant.

The one wrong statement was the date: 'Since today is Thursday, May twenty-second' on call 4, 'Monday, August twenty-sixth' on call 5. Its effect is graded under booking.

It heard 'Lena' as 'Weena' on call 4 and 'Wayne' on call 5, in its transcripts and in the emails it sent. The name was right on calls 6 and 7, and no price was invented.

Simple Phones dashboard call list: the booking retake at 11:23 PM and the four calls before it, each with its start and end time

Simple Phones booked nothing, on either take, because it believes the date I ask for has already passed: May on the first take, August on the second, with the calendar shared. There is no date, time-zone or calendar setting I could have got wrong, and the system prompt is the vendor's default, so the fault is the product's.

Every failed attempt ended in an email to the office within the minute, so a person can book by hand. I have no booking confirmation of any kind, so I treat nothing as booked.

Eight message emails for eight messages taken, each within about a minute of the agent saying it had sent one, most of them while the call was still going. Every one has the caller's name, the number and the message.

The two graded messages: Daniel Whitmore's has every field, including the spelled surname and the 'after four' note. Sam Delgado's has no address, because the agent never asked. That missing field is the difference between a 4 and a 5.

Each email is three lines, name, phone and message, with no transcript or recording link. All eight carry the same subject line, so Gmail stacked them into one conversation.

The 'Email me a summary after each call' box in Settings was not ticked, so I had no transcript summaries. The message emails come through the take-a-message tool without it.

Nothing in Simple Phones can ring the owner. There is no transfer tool and nowhere to put Dan's number, so both emergency calls ended the same way: an email to the account's address within the minute, and a promise the firm never made, 'very shortly' on call 8 and 'immediately' on call 9.

Simple Phones's website says 'Calls can be routed or escalated to different numbers' and 'we can have the call transferred to a member of your team'. The dashboard says 'Click on an agent to chat with it and request changes', and every plan lists 'Free agent revisions'. So a transfer may be something the vendor builds for you; I did not ask, so none was tested.

Whether Dan sees those emails depends on who reads the inbox, and neither has an address.

Six pushes to make Simple Phones invent a price, give a discount or promise something the owner never offered, and all six held: the re-pipe price asked twice, a rival's $80 an hour, the fee waiver, same-day service for no hot water, and 'real person or a computer?'. The replies are in calls 1 to 3. Spam is not tested.

Not tested. The dashboard has no app link, and the website, its FAQ and its help centre mention none. Everything I did was in the web dashboard, and the messages came by email.

• Started the 14-day trial on Basic through Stripe; $0 on the day.
• Created the agent from the business name and a two-sentence description, with the firm's page in the knowledge base.
• Left every default: the four tools on, the voice 'Jessica - Playful, Bright, Warm', the model 'Gemini 3 Flash (fast, default)' and the vendor's system prompt.
• Accepted the shared Google calendar's invitation before the second booking take.

Yes, if answering and message-taking is the job. It never guessed a price, never gave in to a push, and never claimed a message it had not sent.

No, if you need it to book or to put a caller through. The booking tool failed on both takes, and the only route to the owner is an email, so an emergency caller waits on whoever reads the inbox.

I took 0.2 off the measured score for two habits: 'I've cleared your original slot' when nothing existed, and call-back promises, 'very shortly' and 'immediately', that the firm never gave. A fix for the date bug would change the booking grade and the rating with it.
