Verdict
Verdict: A reliable, genuinely free second number for US/Canada use, best if you can tolerate ads and occasional quirks.
Who is it for
Best for:
- Users needing a separate work/personal line on one device
- People who want free US/Canada calling and texting over Wi‑Fi/data
- Small businesses and side hustles needing a budget-friendly second line
Not ideal for:
- Those who require guaranteed SMS verification with every service (e.g., some apps reject VOIP numbers)
- Users who want zero ads and carrier-grade reliability without a subscription
- Travelers needing consistent international texting/voice without Wi‑Fi/data
Real-world User Experience
Users like it:
Truly free unlimited calls/texts in the US/Canada without credit systems; stable performance for most, with many reporting years of use on the same number; simple setup, pop-up chat heads, voicemail, MMS, and accurate notifications; helpful, responsive support; effective for separating business and personal communications.
Users complain about:
Ads (usually unobtrusive, but present); occasional glitches or call issues if battery saver is on or signal is weak; VOIP numbers sometimes fail for account verification on certain services; free numbers can expire after inactivity unless you pay to reserve; premium price (~$9.99/month) may feel high for ad removal/number permanence.
Is it Worth Paying For?
The free tier is excellent for most—unlimited US/Canada calling and texting with manageable ads. Paying makes sense if you need to reserve your number, remove ads, and use it more professionally (e.g., business branding/reliability). If you only need a casual second line, stick with free; if this is a core business line, the subscription can be worth it.
How it Compares to Alternatives
Compared to TextNow (same family), 2ndLine offers a similar, familiar experience with strong reliability reports from users. Versus Burner/Hushed, 2ndLine is far cheaper for ongoing use (those often charge per line or credit-based usage). Against Google Voice, 2ndLine is easier to start, not tied to a Google account, and more accessible, though Google Voice may integrate better with other Google services and can be more verification-friendly. Many competitors gate calling behind credits; 2ndLine’s unlimited free US/Canada calling is its standout edge.
Summary
2ndLine is a standout option if you want a no-cost second US/Canada phone number for calls and texts over Wi‑Fi/data. It’s simple, stable for most, and feature-rich (MMS, voicemail, caller ID, custom tones), with responsive support and an ad model that doesn’t get in the way for many users. The main caveats are VOIP limitations for certain verification texts, the need for solid connectivity, and free-number inactivity rules. For casual personal or small-business use, the free tier shines; if you need an ad-free, always-on business line with number permanence, the paid plan is a practical upgrade.
