Best Business Phone Number for Solo Founders (2026 Prices)

Short answer: For most solo founders in the US or Canada, the best business phone number app is Quo Starter: $15 per user per month billed annually ($19 monthly), one number, and US and Canada calling and texting on your own mobile. If you only need a clean second line at the lowest price, Google Voice Starter at $10 a month is the budget pick, and Grasshopper True Solo suits a classic virtual number with extensions later.

Every price below comes from the vendor's own page, checked on 12 Nov 2026. The recommendations in between are ours and marked as such.

TL;DR#

• Best overall for one person: Quo Starter, $15/mo annual or $19/mo monthly, extra numbers $5/mo (Quo pricing).
• Cheapest serious option: Google Voice Starter, $10 per user per month, sold as Voice only for one user in the US (Google Voice).
• Classic virtual line: Grasshopper True Solo, from $14/mo billed annually, 1 user and 1 extension (Grasshopper pricing).
• Budget for texting compliance: US business texting needs A2P 10DLC registration, around $19.50 one-time plus a small monthly fee (Quo help center).
• Skip team call-center tools until you hire: Aircall needs at least 3 licenses (Aircall pricing).

What a solo founder actually needs from a business line#

You want a number that is not your personal mobile, rings on your mobile anyway, and can be switched off at 6pm. That means one local or toll-free number for your site and invoices, calls and texts from an app plus a desktop app, voicemail transcription, business hours with auto-replies, and room to add a person later without changing the number.

Our read: most bootstrapped software founders get very few calls. The line mostly exists for trust, the odd sales call and texts from customers, so price per seat and texting rules matter more than call-center features.

Comparison table: 11 business phone apps plus Dual SIM#

All prices are USD per user per month unless marked. "Annual" means the price shown when billed yearly.

Notes on the table:

• Dialpad's Standard signup link is set to yearly billing, so treat $15 as the annual rate.
• Nextiva's footnote says annual pricing needs "a paid 12-month or longer minimum term agreement".
• JustCall was running a Black Friday banner when we checked, so the $29 may be promotional.
• Zoom describes this plan as "Phone US & CA Unlimited added to Workplace Basic".

The top picks in more detail#

Quo: best overall for a solo founder#

Quo's site title reads "Quo (formerly OpenPhone)" (Quo). Starter is $19 per user per month, or $15 billed annually at $180 a year. Each user gets "One new or ported phone number (local or toll-free)", and US and Canada calling and messaging are included under a fair use policy. Other countries are charged per minute and per message (Quo pricing).

Business is $33 monthly or $23 annually and adds AI call summaries for all calls. Extra numbers are $5 a month each, which is handy if you want a separate line per product.

Our read: Quo is the closest thing to "a second phone in an app", and if you hire a support person you can share the number instead of handing out your mobile.

Google Voice: cheapest for one person in the US#

Google Voice Starter costs $10 per user per month. For one user it is sold as "Get Voice Only" and is "Available in the US". The 10-user Starter, Standard ($20) and Premier ($30) are add-ons to a Google Workspace plan (Google Voice).

Google also has a free personal Google Voice product; its help page says "If you're in the US, you can choose your own number" (Google Voice help). Our read: a personal account is a poor home for a number printed on your invoices, so pay for Starter.

Grasshopper: a classic virtual number#

Grasshopper's True Solo plan starts at $14 a month billed annually, for 1 user and 1 extension. Solo Plus and Small Business are listed at $25 and $55 in the page's structured data. Extra numbers cost $10 a month on monthly billing or $9 a month on annual billing. Grasshopper offers a 7-day trial with no credit card (Grasshopper pricing).

Our read: Grasshopper suits founders who want an IVR menu ("press 1 for sales") and extensions that forward to different phones. If you need call recording, True Solo does not include it.

RingCentral and Zoom Phone#

RingCentral Core is $20 per user per month paid annually or $30 monthly (RingCentral pricing); Zoom Phone US & CA Unlimited is $18 monthly or $16 annually (Zoom Phone pricing). Our read: good if you already live in Zoom or need desk phones, but more system than a one-person company needs, and RingCentral Core's 25 texts per user a month is thin if customers text you.

Business texting: A2P 10DLC and toll-free verification#

This is the part most founders miss. Twilio's documentation says: "Anyone sending SMS/MMS messages over a 10DLC number from an application to the US must register for A2P 10DLC" (Twilio). Registration runs through The Campaign Registry, which says direct registration by brands "is not available", so your phone app registers you.

What it costs, from the vendors' own pages:

Quo adds a $15 resubmission fee if an application is rejected. It also says "only paid Quo customers can complete carrier registration", so the trial is not enough. Most approvals take 24 to 48 hours, but some have stayed pending for up to 20 days.

Toll-free numbers need separate verification. Twilio says its toll-free numbers can't send SMS messages to the United States and Canada "until you've completed toll-free verification" (Twilio toll-free). Quo says toll-free registration is free and can take 2 to 3 weeks (Quo toll-free registration).

Our read: register on day one, before you launch. Texts that silently fail during your launch week are worse than having no texting at all.

Porting your existing number#

Quo's porting guide says "most ports are completed in 3-7 business days", charges nothing to port in or out, and needs your account number and account PIN from your current carrier. It warns: "Don't cancel your current service until the port is complete" (Quo porting). Verizon's port-out page says the same and asks for a Number Transfer PIN (Verizon).

Our tip: if you port your personal mobile number, get a new mobile number first, because the ported number leaves your carrier plan.

Call recording and consent#

California Penal Code 632 covers anyone who, "intentionally and without the consent of all parties to a confidential communication", records it, with fines of up to $2,500 per violation (Cal. Penal Code 632, via California Public Law; the official leginfo site blocked our request). Rules differ by state, and your callers can be anywhere. In the UK, recordings are personal data, so check the ICO's guidance for organisations first. This is not legal advice.

Our read: if you record, play a short "this call may be recorded" greeting on every call, and only keep recordings you actually use.

AI receptionists: what they cost#

Several apps now sell an AI agent that answers when you cannot:

• Quo Sona: 1,000 free automation credits (10 calls) on every plan, then tiers from $25/mo for 40 calls to $199/mo for 600 calls (Quo pricing).
• RingCentral AI Receptionist: an add-on that "Starts at" $39 (RingCentral pricing).
• Nextiva XBert AI Employee: $99 a month, with packages starting at 100 conversations a month (Nextiva pricing).
• Aircall AI Voice Agents: $99 per month minimum standalone; Essentials includes 50 minutes a month (Aircall pricing).
• JustCall AI Voice Agent: first 100 minutes free, volume discounts down to $0.15 a minute (JustCall pricing).

Our read: start with a good voicemail greeting plus an auto-reply text, and pay for an AI receptionist only once missed calls cost you sales. Our guide on handling support as a solo founder covers how to keep phone support from eating your week.

The no-app option: Dual SIM or eSIM#

Apple's support page suggests you "Use one number for business and another number for personal calls" with Dual SIM (Apple); you pay your carrier for a second plan. Our read: fine on the move, but you lose the desktop app, auto-replies and the ability to hand the number to a hire.

Worked example: year-one cost for one founder#

Illustrative example (our arithmetic, using the prices above): one founder, one US number, texting customers as a sole proprietor.

The difference between the three solo-friendly picks is about $100 a year. The real cost gap is buying a team tool you do not need.

Decision table#

This is our editorial advice, based on the prices above.

How to set it up in an afternoon#

1. Pick the app, start the trial, and choose a local number or port your existing one.
2. Upgrade and register for A2P 10DLC right away so texting works before launch.
3. Set business hours, a voicemail greeting and an auto-reply text for missed calls.
4. Put the number everywhere: site footer, receipts, invoices and your CRM, and log the renewal date alongside your solo SaaS tech stack.

Frequently asked questions#

What is the cheapest business phone number for a solo founder?#

Of the paid business apps we checked, Google Voice Starter at $10 per user per month is the cheapest for one person in the US, sold as Voice only. Vonage's UK Express plan is £10 per user per month excluding VAT, but outbound calls are metered. Quo Starter is $15 per month on annual billing and includes unlimited US and Canada texting under fair use.

Can I use a free Google Voice number for my business?#

Google offers a free personal Google Voice number, and its help page says that if you are in the US you can choose your own number. It is a personal product. For a business line, Google sells Google Voice Starter at $10 per user per month, which is the edition built for business use.

Do I need to register to send business texts in the US?#

Yes. Twilio's documentation says anyone sending SMS or MMS over a 10DLC number from an application to the US must register for A2P 10DLC. Your phone app handles the paperwork. Quo lists a $19.50 one-time fee and $1.50 to $3 per month, and toll-free numbers need separate toll-free verification, which Quo says is free.

Can I move my existing number to a business phone app?#

Usually, yes. Quo says most ports finish in 3 to 7 business days, it charges nothing to port in or out, and you will need your account number and account PIN from your current carrier. Do not cancel your old service until the port is complete, or you risk losing the number.

Is a second SIM or eSIM a good alternative to a business phone app?#

It can be. Apple's support page says Dual SIM lets you have two active numbers and suggests using one number for business and another for personal calls. You lose the shared inbox, desktop app, auto-replies and easy handover a business phone app gives you, so it fits founders who mostly take calls on the move.
