Line2 Alternatives for a Business Second Line

Short answer: Line2 gives one person a business number on their own phone from $15.99 per month. If you want something cheaper, look at Google Voice (free Basic or $10 Starter) or Sideline ($14.49 per month). If you want something that grows with a team, look at Grasshopper (per-plan pricing from $14 per month), Quo ($19 per user), Phone.com ($18 per user) or Callata ($99 per month including five users, then $20 per extra user).

Prices are from each vendor's pricing or help page, checked October 1, 2026, and exclude taxes and fees.

What Line2 offers

Line2's business plans are Starter ($15.99 monthly, $13.75 annually), Growth ($20.99, $17.66) and Business ($25.99, $21.83), plus a basic second-number plan at $9.99 ($7.99 annually). Each includes a local or toll-free number, unlimited US and Canada calls and texts (subject to overages in its terms), call blocking, call screening and voicemail. Growth adds an auto-attendant and call scheduler; Business adds call recording, voicemail transcriptions and advanced reporting. Every business plan carries a 30-day money-back guarantee.

Why people look elsewhere

• They want it cheaper. For a personal second number, Line2's paid plans cost more than free or low-cost options.
• They have hired someone. Line2 is one line per person, with no shared inbox or ring group across lines.
• They want AI. Line2's plans center on calls, texts and voicemail, without AI summaries or AI answering.

If none of these apply, Line2 is doing its job and switching will not save you much.

1. Google Voice

Google Voice's individual plans are Basic ($0, requires an existing mobile number), Starter ($10 per month, adding support, recording and desk phone support) and Standard ($20, adding auto attendants and Gemini call notes). Team plans require Google Workspace.

Versus Line2: cheaper, especially the free tier, but the free tier is tied to a personal Google account and lacks support. See Google Voice pricing explained.

2. Sideline

Sideline costs $14.49 per month, $69.99 for six months or $129.99 per year. Calls run over your carrier network, and it includes unlimited messaging, auto-replies to missed calls and spam labeling.

Versus Line2: similar job, with strong texting features and carrier-network calling. See Callata vs Sideline.

3. Grasshopper

Grasshopper True Solo is $14 per month billed annually for one number and extension; Solo Plus ($25) adds three extensions and unlimited users; Small Business ($55) adds four numbers and unlimited extensions.

Versus Line2: the natural step when a second person needs to share the business number. See Grasshopper pricing explained.

4. Quo (formerly OpenPhone)

Quo Starter is $19 per user monthly ($15 annually) with a number per user, shared numbers, calling, texting, voicemail transcripts and the Sona AI agent. Business ($33) adds AI summaries for all calls and phone menus.

Versus Line2: a team-ready app with AI, priced per user. See Quo pricing explained.

5. Phone.com

Phone.com Basic is $18 per user monthly ($15 annually) with unlimited minutes, an auto attendant, video meetings and fax. Plus ($27) adds texting and voicemail transcription.

Versus Line2: more office-phone features per user, including video and fax. See Phone.com pricing explained.

6. Callata

Callata is a team phone system for $99 per month including five users, plus $20 per month for each additional user, with up to three local numbers, unlimited inbound calling and a pooled allowance of 1,500 outbound US and Canada minutes per user per month (then $0.01 per minute), ring groups, extensions, business-hours routing, a shared texting inbox (after a one-time $49 10DLC registration), call recording with AI summaries, voicemail transcription with urgency triage and E911. AI agents answer and place calls at $0.25 per minute.

Versus Line2: costs more than Line2 Starter at every team size on list price ($99 for five users against $79.95 for five Starter lines), but keeps conversations with the business and adds shared numbers, ring groups and AI summaries. Against Line2 Business ($25.99), the plan with recording and transcription, Callata costs less from four users ($99 against $103.96). See Callata vs Line2.

Cost by number of people

People	Line2 Starter (monthly)	Google Voice Starter (individual)	Grasshopper (annual)	Quo Starter (monthly)	Callata
1	$15.99	$10	$14 (True Solo)	$19	$99
2	$31.98	Team plan + Workspace	$25 (Solo Plus)	$38	$99
4	$63.96	Team plan + Workspace	$25 or $55	$76	$99
6	$95.94	Team plan + Workspace	$55 (Small Business)	$114	$119

On list price, Callata is the most expensive option in this table at every team size; what it adds is a shared business number, ring groups, a shared texting inbox, recording with AI summaries and AI answering.

What to look for in a second-line service

1. Who owns the number. If the number should stay with the business when people change, choose a system with shared business numbers.
2. Texting registration. Business texting from US local numbers needs carrier registration on most business-grade services. Check the fee and timeline.
3. Toll-free. If you want a toll-free number, Line2, Grasshopper and Quo offer one; Callata does not.
4. Recording and transcription. On Line2 these are on Business. Check which plan includes them elsewhere.
5. Support. Line2 lists a sales line on weekdays; compare support channels if you will rely on them.

A note on carrier-network vs internet calling

Second-line apps differ in how calls travel. Sideline says it uses your carrier's network, so calls do not depend on Wi-Fi. Line2, Google Voice, Quo and Callata are internet-based (VoIP), so call quality depends on your data or Wi-Fi connection; Callata can also ring your cell phone so you can answer on the device you carry. If you often work in places with weak data coverage, test call quality on your actual routes before committing.

When to stay with Line2

If you are a single professional who wants a private number with call screening and an optional toll-free number, Line2 does that job well, and its 30-day guarantee makes it low-risk.

Switching checklist

• Decide which numbers move, and whether any stay as private lines.
• Confirm your new provider supports your number type (local or toll-free).
• Register for texting where required.
• Port the number and keep Line2 active until the port completes.
