Three clients had my personal cell number. I started losing sleep. Here’s the fix.
At 9:47pm on a Tuesday last November, a client texted me a screenshot of a logo draft and asked if I could “just tweak the kerning” before his investor call at 8am. I was standing in my kitchen in sweatpants, holding a spoonful of peanut butter, and I felt my jaw tighten so hard I almost cracked a molar.
He was not a bad client. He was excited and anxious, and he genuinely forgot that freelancers have evenings. The problem was that he had my personal cell number, which meant there was no buffer between his panic and my living room. Every text came through on the same phone where my mom sends photos of her garden and my best friend sends voice memos about bad dates. Work had colonized the one device I use to decompress.
I bought a virtual business number the next morning. That was seven months ago. I have used four different services since then, and one of them is now so embedded in my workflow that losing it would feel like losing my email address.

The short answer on virtual business numbers
Freelancers who blur work and personal life on one phone number will eventually regret it. The best fix is a dedicated virtual business number. OpenPhone is the best option for most solopreneurs because it separates calls, texts, and voicemails into a clean business profile with auto-replies and shared inboxes. If you only need a basic second number and you are in the US, Google Voice is free and works fine for pure separation.
Why your personal number is a liability
Most freelancers start by giving clients their personal cell number. It feels natural. You already have the phone. The client can reach you instantly. You don’t have to learn a new app. It is the path of least resistance, and it is a slow poison.
Your personal number becomes a public record. It goes on contracts, invoices, business cards, and LinkedIn profiles. Once it is out, you cannot control who has it. Former clients pass it to colleagues. Prospects save it before you have agreed to a scope. Scraper bots pick it up from PDFs you uploaded to portfolio sites. Within a year, your personal phone is a broadcast channel for anyone who found your name on the internet.
The tax implications are annoying too. In some jurisdictions, business-related phone expenses are deductible, but only if you can prove the line was used primarily for business. Mixing personal and business calls on one number makes that bookkeeping messy. A separate number creates a clean boundary that your accountant will appreciate.
And then there is the psychological cost. Every buzz of your phone becomes a potential work intrusion. The boundary between your job and your life is porous, and clients can feel it. The ones with poor impulse control will text you on weekends, on vacation, and during dinner, not because they are evil, but because you gave them a direct line to your pocket and did not build a gate.
What I looked for in a second number
When I started testing virtual phone services, I had a short list of requirements based on my actual daily workflow.
Real SMS and MMS support
Some cheap virtual number services only handle voice calls. Freelancers live in text messages. Clients send screenshots, approvals, and quick questions via SMS. If a service can’t handle both images and group texts, it is dead on arrival for modern client communication.
Professional voicemail and auto-attendant
A virtual number needs to do more than ring your phone. It should greet callers with a professional message, route them to voicemail if you are unavailable, and ideally offer business hours so calls outside your working window go straight to a polite automated response.
Call and message separation
The whole point is separation. A good service keeps business calls, texts, and voicemails in a distinct app or tab, so my personal messages never mingle with client threads. Ideally, the app also supports multiple devices so I can answer from my laptop during work hours and my phone when I am out.
Portability and ownership
I refuse to rent a number I cannot keep. If I decide to switch providers in two years, I want to port that number out like any other phone line. Some budget services lock you in by refusing to release numbers. That is a dealbreaker.
Pricing under $20 per month
A second number is overhead, not revenue. If it costs more than my Spotify subscription, it had better deliver exceptional value. Most freelancers can justify $10 to $15 a month for peace of mind and professionalism. Above that, the ROI gets harder to defend.
Best overall: OpenPhone
OpenPhone is the service I pay for now, and it is the one I recommend to every freelancer who asks about virtual numbers. It costs more than the budget options and it launched later than Skype. Yet it is the only one that actually feels like it was built for people who work alone and talk to clients for a living.
What OpenPhone does well
The app design is genuinely clean. I have used enough clunky business telephony apps to know that most of them look like they were built in 2008 by engineers who hated their users. OpenPhone feels like a modern messaging app. Threads are organized by contact. Voicemails are transcribed automatically. Call recordings are stored with timestamps. I can search through six months of client texts by keyword, which has saved me more than once when a client claimed we had discussed a scope change we never actually agreed to.
Auto-replies are the feature I didn’t know I needed until I had it. I set mine to trigger outside business hours, which I define as 8am to 6pm in my time zone. If a client texts me at 9pm, they immediately receive a polite message: “Hi, thanks for reaching out. I’m currently offline and will respond during business hours tomorrow. If this is urgent, please call.” That single auto-reply prevented at least three boundary violations in my first month.
The shared inbox is useful if you ever grow beyond solo work. I don’t have an assistant yet, but I do collaborate with a subcontractor on large projects. With OpenPhone, I can share specific client threads with her without giving her my personal number or forwarding screenshots. She sees the conversation inside the app and can reply from her own device.
Call quality is solid on both WiFi and cellular. I have taken calls from cafes in Prague, hotel rooms in Mexico City, and a bench outside a laundromat in Lisbon. Audio was clear, latency was low, and I never had a client complain about echo or dropouts.
Pricing starts at $15 per user per month for the Standard plan, which includes one local or toll-free number, unlimited calls and texts in the US and Canada, voicemail transcription, and auto-replies. The Premium plan at $23 adds call recording, analytics, and hub integrations. I am on Standard and it covers everything I need.
Where OpenPhone falls short
OpenPhone currently only supports US and Canadian numbers. If you are based in Europe, Asia, or elsewhere, you cannot get a local number here. The company says international expansion is on the roadmap, but freelancers outside North America need to look elsewhere for now.
The mobile app is reliable but occasionally slow to sync when I open it after a day of not using it. The first time I launched it after a flight, it took about eight seconds to populate my message threads. Not a dealbreaker, but noticeable when a client is waiting.
There is no native desktop calling integration with macOS or Windows contacts. I have to add client numbers manually into OpenPhone, which is fine for my volume but would annoy people with hundreds of contacts.
Non-affiliate alternative: Google Voice remains the best free option in the US. It gives you a real phone number with SMS, voicemail transcription, and call forwarding. The interface is dated, and it has none of the business features that make OpenPhone worth paying for, but as a pure separation tool it is unbeatable at zero dollars.
Best for international freelancers: Skype Number
Skype Number is the service I used when I spent four months in Europe last year and needed a US number that would not trigger roaming fees every time a client called. It worked well enough that I kept it as a backup even after switching to OpenPhone for my primary line.
What Skype Number does well
The biggest advantage is coverage. Skype Number supports numbers in 25 countries, which is far more than OpenPhone. If you need a UK number for local credibility, an Australian number for APAC clients, or a German number for EU contracts, Skype is one of the few affordable options.
Incoming calls ring through the Skype app on any device. I answered client calls on my laptop while working in a co-working space in Berlin, and on my phone while walking to the metro in Lisbon. Because the call travels over data rather than cellular voice, I paid nothing in roaming fees. That alone saved me probably $80 in international charges over four months.
Voicemail is included and messages are stored in the Skype app with playback. You can set up call forwarding to a regular phone number if you want, though that incurs per-minute charges.
Where Skype Number falls short
The interface is unmistakably Microsoft. It is functional, gray, and slightly hostile. Finding a specific past message requires scrolling through a chronological list with no search in the mobile app. On desktop, search exists but is slow.
Skype Number does not support business SMS well. You can send text messages to some mobile numbers, but MMS and group text are unreliable or unsupported depending on the recipient’s carrier. For modern client communication that relies heavily on image sharing and group threads, this is a genuine limitation.
Pricing is pay-as-you-go or subscription. A Skype Number costs roughly $6.50 per month if you commit to a year, plus any calling minutes you use beyond the included inbound. Outbound calls to regular phones cost per minute. For heavy use, the costs can creep past OpenPhone’s flat rate.
Best for solo professionals who want simplicity: MightyCall
MightyCall is the service I tested for two weeks before settling on OpenPhone. It is a solid middle ground between OpenPhone’s slick modernity and Skype’s international breadth, though it never quite clicked for my specific workflow.
What MightyCall does well
The call menu feature is excellent. You can set up a simple auto-attendant that says “Press 1 for new projects, Press 2 for billing, Press 3 for everything else” and route calls accordingly. This makes a solo freelancer sound like a small firm, which is not deception so much as signaling that you have systems.
Voicemail transcription is accurate and fast. I tested it with a thick accent, a fast-talking client, and a call from a construction site with background noise. All three transcripts were readable, though the construction site call had a few errors.
MightyCall includes two numbers on the base plan, which is nice if you want one for general client inquiries and a separate one for billing or a specific service line.
Where MightyCall falls short
The mobile app feels older than it should. Navigation feels clunky, and syncing between devices is slower than OpenPhone. I had one instance where a voicemail showed up on my laptop ten minutes before it appeared on my phone.
At $15 per month for the base plan, MightyCall costs the same as OpenPhone but offers a less polished app and no shared inbox on that tier. The feature set is competitive on paper, but the user experience gap is real.

How I test virtual phone services
My testing protocol is simple and based on real client workflows rather than spec sheets.
First, I port or claim a number and use it as my primary client contact for a minimum of ten days. That includes taking at least five voice calls, sending and receiving text messages with images, and testing the voicemail and auto-reply features. Ten days is long enough to encounter real-world issues like delayed notifications, poor call quality in a cafe, or UI friction.
Second, I test call quality under stress. I take calls on hotel WiFi, on cellular data while walking outdoors, and in busy co-working spaces with dozens of competing wireless signals. Any service that drops calls or creates noticeable latency gets marked down. Freelancers travel, and a virtual number that only works on your home fiber connection is worthless.
Third, I evaluate the boundary features. Does the auto-reply work automatically? Can I set business hours without needing a computer science degree? Does the app distinguish business notifications from personal ones, or do they all look identical in my phone’s notification shade? Boundary protection is the main reason to get a second number, so a service that makes it hard to configure is missing the point.
Finally, I check pricing transparency. I look for hidden setup fees, per-minute overages, and number porting costs. A service that advertises $15 a month but charges $40 to port your number in is not actually $15 a month.
Why I will never go back to one number
The biggest change is mental, not technical. Before I got a virtual number, every buzz of my phone triggered a small spike of dread. Is it a client emergency? Is it a scope creep text? Is it someone asking for free advice? Now I know before I look. If my personal phone buzzes, it is probably family or a friend. If the OpenPhone app buzzes, it is work, and I can choose whether to engage based on the time and my current capacity.
Clients also treat the number differently. They are less casual over a business line. Texts are more likely to include full sentences and clear requests. The auto-reply sets expectations without me having to type “I am offline” manually every evening. It is a small automation that replaces a huge amount of emotional labor.
My accountant is happier too. Business call logs, text records, and voicemail transcripts are all stored in one app. At tax time, I export the records and hand them over. No more scrolling through my personal phone trying to remember which calls were deductible.
Questions freelancers ask about second phone numbers
Can I use a virtual number for business registration and taxes?
Yes, in most jurisdictions a virtual number counts as a valid business contact. For LLC registration, you typically need a physical address too, but the phone number can be virtual. Check with your local tax authority for specific rules.
Will clients know it’s a virtual number?
No. Virtual numbers look identical to regular mobile or landline numbers. They support caller ID, voicemail, and SMS. Clients cannot tell the difference unless you mention it.
Is there a free option that works for freelancers?
Google Voice offers a free virtual number in the US, but it lacks business features like auto-replies, call menus, and team sharing. For serious use, a paid service is worth the small monthly cost.
Can I keep my virtual number if I switch services?
Most paid services support number porting in and out. Google Voice also lets you port out for a small fee. Always confirm porting policies before you commit to a provider.
Who should skip a second number for now
If you are a part-time freelancer with one client and you already communicate exclusively over Slack or email, a business phone number is probably overkill. Add it once you have multiple clients, any client who calls instead of Slacks, or a creeping sense that work is leaking into your evenings.
If you live outside the US and Canada, OpenPhone will not work for you yet, so the upfront choice is between Skype Number and MightyCall, depending on whether you need international coverage or call menus. Weigh the cost against how often clients actually call you. Some freelancers live in email and never need a phone line at all.
Start here
Buy a virtual number before your next client asks for your cell. If you are in the US or Canada, OpenPhone is worth the $15 a month for the auto-replies alone. If you want to test the concept without spending anything, grab a free Google Voice number and route it to your phone for a month. Either way, separate your business voice from your personal life. Your evenings belong to you again.
