Your number is already on the truck
Most owners looking for a second phone number for business assume the new number becomes the business line. Usually it's the opposite: keep the number customers already have, and take the new one for yourself. Beside can answer either number, and port or forward the one you keep.
Owners who've run their whole business on one number for years show the same pattern: the number outlasts every other decision. It's on the truck, the invoices, the yard signs, and every customer's contacts. The change itself, not the software, is the real cost of moving it.
| Question | Answer |
|---|---|
| Who this is for | A solo or two-person service business running on one phone number for years. |
| The decision | Which of your two numbers becomes the business line — usually the one already published. |
| If the number has to move | Budget for new signage and cards (get a local quote; prices vary by shop), plus a possible Google Business Profile re-verification, which can take up to five business days when contact details change. |
| What Beside does | Answers the number you already give out, books, qualifies, transcribes and summarizes calls — 24/7 by default, with configurable business hours. |
| Price | Baseline: $29.99/mo, 30 AI-answered calls/month (behavior beyond the cap is unpublished). Unlimited: $99.99/mo, no cap, 7-day free trial. Extra lines $4.99/mo. |
| Proof | 4.8 out of 5 across 9.1K App Store ratings. |
| How to start | Port your number in, or forward it from your carrier — nothing on the truck changes. |
So which number moves?
The business keeps the number already published; the new number becomes yours. That works because the kept number doesn't have to sit with your old carrier to be answered. Beside supports both porting and call forwarding from your existing carrier. Porting typically completes in under a week, sometimes up to two; forwarding leaves the number with your carrier with no downtime. A new local or toll-free number for yourself gets set up through Beside — that's the one you hand to your kid's school.
| Item | New number goes to the business | New number goes to you (default) |
|---|---|---|
| The truck, signs, cards | Re-letter and reprint | Nothing changes |
| Customers dialing the old number | Reach your personal phone, forever | Reach the business line, answered |
| Google Business Profile | Edit it, possibly re-verify | Leave it alone |
| Evenings | The old number still rings in your pocket | The business line is handled |
| Who has to be told | Everyone you've ever worked for | Family and friends |
If the number you publish is also the phone in your pocket, forward it: it stays with your carrier, so bank logins and two-factor codes keep landing where they always have, and Beside answers it anyway. Port it only if the business number is genuinely separate. Note: porting a mobile carrier number cancels its data plan, since Beside provides no mobile data; porting a toll-free number disables outbound texting on it afterward.
Your business line stops being the one in your pocket at dinner. Beside answers the number you already give out, in a voice cloned from yours, and books, qualifies and summarizes while you're under a sink or on a roof. Baseline is $29.99/mo with 30 AI-answered calls a month; Unlimited is $99.99/mo with no cap and a 7-day free trial. The app holds 4.8 out of 5 across 9.1K ratings. Port your number in, or forward it — nothing on your truck changes.
A second number splits the ringing — it doesn't answer it
A second line buys one real thing: your personal number stops being public. It stops short of an answered phone. What it adds on its own is a second voicemail box to work through at nine at night. None of the plain second-number apps below turn a missed call into a record of what the caller actually needed — that's the gap this guide is really about.
With a single number, every ring carries the same uncertainty: is this a booking, or is something on fire? Splitting numbers only tells you which line rang. It doesn't tell you what the caller wanted, and it doesn't answer for you while you're on a ladder or under a sink.
Compare second-number apps on what actually matters
Bounded to four criteria for this decision: whether the number stays reliably yours, whether both calls and texts are covered, whether business hours are respected, and whether customer conversations are kept as a record afterward.
| App | Stable ownership | Calls & texts | Business hours | Customer records |
|---|---|---|---|---|
| Google Voice | Conditional — Google's own admin documentation describes releasing and reclaiming unused numbers | Calls and texting are part of the free personal tier (widely documented, not independently re-verified this session) | Not advertised on the free personal tier; a scheduled auto-attendant exists only for Workspace admins managing Voice for an organization | None |
| Sideline | Runs on your own carrier network — a stability edge over pure VoIP apps | Unlimited texting | Manual Auto-Reply only, not scheduled | Not advertised |
| Quo / OpenPhone ($19/user/mo, $15 annual) | Dedicated VoIP number | Unlimited, but texting needs a one-time $19.50 TCR fee plus $1.50–3/mo | Business Hours feature mutes after-hours notifications | Shared contact notes; AI agent included |
| Grasshopper (True Solo $14/mo, Solo Plus $25/mo, Small Business $55/mo) | Dedicated number, built around shared extensions | Unlimited minutes and texting included on all tiers | Virtual receptionist with a configurable business-hours setting | None advertised |
| Beside (Baseline $29.99/mo or Unlimited $99.99/mo) | Port or forward your existing number | Unlimited US/Canada calling and texting on both tiers | 24/7 by default, configurable business hours and after-hours greeting | Transcripts, summaries and a daily recap of every call |
Grasshopper's pricing is confirmed on Grasshopper's own site: True Solo at $14/month for one user, one number and one extension, Solo Plus at $25/month for unlimited users on one number with three extensions, and Small Business at $55/month with four numbers and unlimited extensions — all with unlimited minutes and texting, plus a virtual receptionist and a business-hours setting. Grasshopper's live pricing page itself was inaccessible from this research session, so this is sourced from Grasshopper's own about-us reference page; worth a quick spot-check before publish. Beside's Baseline caps AI-answered calls at 30 a month; what happens beyond that cap isn't published anywhere we could find, so budget for Unlimited if call volume is uncertain. Sideline and Grasshopper don't advertise a way to keep a record of what was said on a call the way Beside and Quo do.
What "answered" means on the line you keep
Beside's receptionist answers, books and qualifies, transcribes and summarizes every call, and sends a daily recap. It runs 24/7 by default, including evenings, weekends and holidays. Calls and texts to the US and Canada are unlimited on the line, so the number customers already text stays the number they text.
The honest limit: the line doesn't go dark at seven. You set working hours, which govern when calls and notifications reach you, so an 8:40pm ring becomes a waiting summary instead of an interruption during dinner — the AI keeps picking up either way. (Exact after-hours greeting behavior should be confirmed in the Help Center before you rely on it for a specific script.)
One pricing note worth flagging: Beside's App Store listing still advertises a flat $29.99/mo or $199.99/yr with a blanket 7-day trial, but its own in-app-purchase tier list shows several mutually inconsistent prices for the same plans. That listing is a legacy pricing surface — the current, authoritative figures are the Baseline/Unlimited split on beside.com/pricing, and the 7-day trial currently applies to Unlimited only.
What has to change if the number really does move
Sometimes the old number genuinely has to go: a shared family line, a partnership that ended, an area code from a city you left. Then the work isn't in the app but in the places the number is published — one of which goes through Google's review queue. Google's own documentation says a verification review can take up to five business days when business details like a phone number are updated, though not every edit triggers re-verification, and phone/SMS verification requires access to the number itself (an IVR line can't receive the code).
- The Google Business Profile and any other directory listing
- The header and footer of the website
- Invoices, estimates and quote templates
- The truck, the trailer, the yard signs
- Business cards, door hangers, fridge magnets
- Review site profiles
- The outgoing voicemail greeting, which says the old number out loud
That list is the real cost of moving a published number, and it's why the cheapest version of this decision repaints nothing.
What to set up, and what to skip
The feature matrix every second-number list ranks on is priced for a business with staff to route calls to. At one or two people, most of it is a maze you built for your own customers.
| Feature the lists rank on | Worth it? |
|---|---|
| Extensions and department menus | No — there's no department, it just adds a step in front of a human |
| Auto-attendant, "press 1 for sales" | No, unless calls genuinely split two ways |
| Toll-free vanity number | No — a local area code signals you're nearby, which is what you're selling |
| A second physical phone | No — the second line is an app on the phone already in your pocket |
| Spam screening on the published line | Yes, worth having — a published number attracts spam calls, and Beside's product pages describe flagging suspected spam calls (not independently re-verified this session) |
| A line that answers when you can't | This is the one that changes the day |
What it costs, both ways
Start at the floor: the cheapest second number is free (Google Voice), and if all you want is to stop handing out your personal cell, it does that job — what it does with a call you can't take is the whole of what you're buying above it. Paid second-number apps with dedicated support and no minute cap are in the same ballpark as Quo's $19/user/mo Starter plan, before any texting registration fees. Beside's Baseline is $29.99/mo for 30 AI-answered calls, and Unlimited is $99.99/mo with no cap and a 7-day trial.
Worked example: a two-person plumbing outfit expecting roughly 20–25 real inquiry calls a month, plus routine texts, fits inside Baseline's 30-call allowance at $29.99/mo — about $360/year. A business fielding 40–50 calls a month, or one that doesn't want to track against a cap, should budget Unlimited at $99.99/mo, about $1,200/year. That's a real gap versus a plain second-number app, and it buys answering, booking and a written record of every call instead of just a private ringtone.
The sign shop only enters the arithmetic in the exception case, where the published number genuinely has to move. Vehicle lettering and card reprints are priced per shop and vary by size and material, so get a local quote rather than assuming a figure. Under the default plan in this guide — keep the published number, take the new one yourself — it's money you never spend.
Setting it up without a gap in coverage
- Decide which number is the published one — for most owners with history, it's the one already on the truck.
- Forward it, or port it. Forwarding leaves the number with your carrier, which is what you want if it's also your personal phone.
- Take the new number yourself. Give it to family, your accountant, the school — the people who aren't customers.
- Set your working hours and after-hours greeting, then let the line answer.
- Follow Beside's step-by-step porting checklist for the exact transfer sequence and expected timing: https://help.beside.com/en/articles/14297122-port-your-number-to-beside
Nothing on the truck changed, and the phone in your pocket is now yours.
