Free second phone number apps have surged in popularity as Americans and Europeans look for smarter ways to separate work and personal life, protect their privacy, and manage online accounts without sharing their primary number. Whether you need a temporary number for Craigslist, a dedicated line for your small business, or an extra SIM-free number for travel, today’s VoIP apps make it possible to call and text using Wi-Fi or mobile data — often at no cost.
Demand has grown alongside remote work, side hustles, and rising concerns about spam calls. According to the Federal Communications Commission, Americans receive billions of robocalls each month, driving more users to shield their real numbers. At the same time, entrepreneurs and freelancers increasingly rely on virtual phone numbers to appear professional without paying for a second physical line.
The best apps for a free second phone number combine reliability, transparent pricing, strong call quality, and robust privacy features. Some offer genuinely free US or Canadian numbers supported by ads, while others provide limited trials before switching to affordable monthly plans. Below is a detailed comparison of the most reputable and widely used services available in 2026.
Google Voice – Free US Second Phone Number for Personal Use
Google Voice
Google Voice remains one of the most trusted ways to get a free second phone number in the United States. Available to users with a Google account, it provides a US-based number for calls, texts, and voicemail at no charge for personal use. It is particularly suited to freelancers, students, and anyone needing a long-term secondary number tied to a stable ecosystem. Domestic calls within the US are free, while international rates are competitively priced. As of January 2026, personal use is free; Google Workspace business plans start at $10 per user per month. Where to buy: Official Google Voice website.
- Free US phone number
- Call forwarding and voicemail transcription
- Spam filtering powered by Google

Its strongest advantage is reliability backed by Google’s infrastructure. However, it is only officially available in the US for personal accounts, limiting access for many European users.

Pricing Comparison of Second Phone Number Apps
Free second phone number apps generally fall into three tiers. The first tier includes ad-supported services such as TextNow and Talkatone, which provide free US or Canadian numbers but monetize through advertisements. The second tier includes low-cost privacy apps like Burner and Hushed, where pricing typically ranges from $3 to $10 per month depending on duration and features. The third tier focuses on business communication platforms like Sideline and Grasshopper, with monthly plans starting around $10 to $15.
For users seeking zero monthly cost, Google Voice remains the strongest long-term free option within the United States. However, European users may need to rely on paid alternatives offering international numbers.
How to Choose the Best Free Second Phone Number App
Selecting the right second phone number app depends first on geography. Some providers only issue US numbers, while others offer UK or Canadian options. Verifying regional availability prevents frustration during sign-up.
Privacy requirements also matter. Temporary marketplaces and online dating may call for disposable numbers that can be deleted instantly. In that case, apps like Burner or Hushed provide stronger anonymity controls.
Business users should evaluate voicemail transcription accuracy, call routing features, and CRM integrations. A professional greeting and reliable uptime can directly affect customer trust.
Internet stability is another key factor. VoIP-based apps rely entirely on Wi-Fi or data. Users in areas with weak connections may prefer hybrid services like Sideline that integrate with carrier minutes.
Finally, review long-term pricing. A free trial may appear attractive, but monthly renewal rates determine true value over time.
Current Market Prices and Deals
As of January 2026, Google Voice remains free for US personal accounts. TextNow and Talkatone continue offering ad-supported free numbers with optional premium upgrades under $10 per month. Burner’s entry plan sits at $4.99 monthly, while Hushed frequently promotes discounted annual plans below $30 per year during seasonal sales. Business-focused platforms like Sideline and Grasshopper typically range between $10 and $18 monthly depending on features and number count.
Promotions change regularly, especially during Black Friday and back-to-school periods, when annual subscriptions may drop by 30 to 50 percent.
Pro Tips for Using a Second Phone Number Safely
Maintaining activity on free numbers prevents reassignment. Many ad-supported services recycle inactive numbers after 30 days of nonuse.
Link your secondary number to two-factor authentication cautiously. If the app account is lost, access to linked services could be compromised.
Use custom voicemail greetings for business interactions. A professional tone increases credibility immediately.
Avoid sharing disposable numbers with banks or government agencies. Financial institutions often block VoIP numbers for verification.
Regularly review call logs and privacy settings to ensure your real number is never inadvertently exposed.

Conclusion
Free second phone number apps provide a practical solution for privacy, remote work, and side businesses without the cost of an additional SIM card. Options like Google Voice, TextNow, and Talkatone offer genuine no-cost entry points, while services such as Burner and Hushed deliver enhanced anonymity for a modest fee.
The right choice ultimately depends on how you plan to use the number. Casual texting and occasional calls may justify an ad-supported app, whereas entrepreneurs and professionals benefit from paid platforms with stronger branding and routing features. Evaluating privacy needs, reliability, and long-term cost ensures that your secondary number works as an asset rather than a liability.
