Line2 vs Quo (2026): which should you pick?

Pick Line2 if

• Fits if you want a second number on your phone for work or privacy, without carrying a second handset
• Works for people who need to pick an area code or move a number they already have

Look elsewhere if

• Not for you if you need a team phone system, as the site sends business users to eVoice
• Skip it if you call outside the US and Canada, as service covers those two countries only
• Watch out: business texting in the US needs carrier registration
• Tight if you want to try it free, since there's only a 30-day money-back guarantee

Pick Quo if

• Fits if you want a work number on your own phone, apart from your personal one
• Works for a few people sharing one sales or support line who need the same history

Look elsewhere if

• Tight if you're on Starter and want a phone menu or call transfers, as those need Business
• Not for you if you call abroad a lot, since calls outside the US and Canada are billed per minute
• Pricey if Sona answers lots of calls, as each one past the plan's credits costs $0.45 to $1.00
• Watch out: US texting needs carrier registration, $19.50 once plus $1.50 to $3 a month
• Pricey if you pay monthly, at $19 for Starter and $33 for Business, or need extra numbers at $5 each

Line2

• Line2 now presents itself as a privacy second line; the site sends business users to eVoice, so team features such as queues and call routing are not listed.
• Service covers the US and Canada only.
• Business texting in the US needs carrier registration, and the site links 10DLC and toll-free SMS registration pages.
• The pricing page lists a single plan and no team or multi-user tier.

Quo

• Texting US numbers requires carrier registration (TCR): a one-time $19.50 review fee plus $1.50 to $3 a month.
• On Starter, calls are recorded manually only, and phone menus, transfers and CRM integrations need Business or Scale.
• Each extra number costs $5 a month; calls and texts outside the US and Canada are billed per minute or per message.
• Sona calls beyond the plan's credits cost $0.45 to $1.00 each, depending on the credit tier.

Line2

Second number on your own phone

Calls and texts run over Wi-Fi or mobile data in an app, so the number sits beside your main line without a second handset.

Choose your area code

Pick a US or Canada number in the area code you want, or move a number you already have over to Line2.

Unlimited calls and texts

Calls and SMS/MMS inside the US and Canada are unlimited, subject to overages described in the terms of service.

Voicemail transcription

Voicemails arrive as text, and the number has its own caller ID display and its own contact list separate from your main one.

Call blocking

Block telemarketers, spam callers and other numbers you do not want reaching the Line2 number.

Phone, tablet and desktop apps

Apps for iOS, Android and desktop, with the account also reachable from a desktop browser, so texts and calls stay in sync.

Quo

Shared phone numbers

Several teammates can share one number with a common call and text history, internal threads and shared contacts. Starter allows up to 10 users per shared number.

Calling and texting

Unlimited calls and texts to US and Canadian numbers under a fair use policy, with snippets, scheduled messages, auto-replies and group messages.

Sona AI agent

An AI agent that answers calls at any hour. Every plan includes 1,000 credits a month, enough for 10 calls; credit packs run from $25 to $199 a month.

AI call summaries and transcripts

Business and Scale transcribe and summarize every call. On Starter, summaries cover only calls Sona handles; voicemails are transcribed on all plans.

Phone menus and routing

Business adds phone menus, call transfers, group calls and ring orders that ring teammates in batches, plus business-hours forwarding.

Integrations and API

HubSpot and Salesforce need Business or Scale. Pipedrive, Slack, Zapier, Make, Google Contacts and the Quo API are also listed, plus an MCP server for ChatGPT and Claude.
