Signal Reviews FAQs

Generated using AI

Last updated: Nov 04, 2026

What is Signal, and what problem is it built to solve?

Signal is an open-source messaging application built to protect privacy, promote free expression, and enable secure communication. It aims to make private messaging simple while combining end-to-end encryption with features familiar from modern messaging apps.

What company sizes and industries is Signal the best fit for?

Positive reviewer profiles cluster most in small businesses, with representation across mid-market and enterprise organizations as well. The industries most represented include:

Company size — Small Business: Organizations with 50 or fewer employees.
Company size — Mid-Market: Organizations with 51–1,000 employees.
Company size — Enterprise: Organizations with more than 1,000 employees.
Information technology and software: Information Technology and Services and Computer Software.
Computer and network security: Security-focused and computer-networking organizations.

What customer support options does Signal provide, and how do users find the overall support experience?

Signal's support experience comes across as mixed rather than consistently dependable. Users describe getting quick, helpful troubleshooting in some cases, while others have found support unhelpful or have not received a response.

What is the experience like for teams switching to Signal from another tool?

Switching to Signal from mainstream messaging and collaboration tools such as WhatsApp, Slack, Teams, and Skype is mainly driven by a desire for stronger privacy and encrypted conversations. The move can feel familiar because Signal supports everyday messaging and groups, though the transition depends on colleagues and contacts also adopting it; some switchers also cite lower costs as a benefit.

What features or capabilities could make Signal even more useful?

Signal could be more useful with improvements to a few areas of the everyday experience. Recurring requests include:

More dependable delivery and notifications: Make message delivery and alerts more consistent.
Better calling: Improve audio and video call quality and reliability, especially for group calls.
Easier navigation and interface: Make the interface and settings more intuitive for new and regular users.
More options for conversation and community: Expand features such as stickers and emojis, channels or communities, and business-focused tools.
Smoother history and device changes: Make it easier to back up, transfer, and access message history across devices.

Is Signal considered safe and secure for handling data?

Signal is valued for end-to-end encryption and privacy controls, which give users confidence when discussing sensitive work or personal matters. Open-source code and tools such as message expiration and contact verification also contribute to that confidence. Some users still raise concerns about account privacy, security issues, or relying on a phone number, so teams with strict anonymity or security requirements should assess those needs carefully.

"Secure Messaging Across Devices. Perfect for Team Chats and Groups"

5/5

What do you like best about Signal?

I love how secure Signal makes me feel, and how easy it is to use across all my devices. Review collected by and hosted on G2.com.

What do you dislike about Signal?

Nothing really at the moment. It does everything me and my team need it to with the use of chats and groups. Review collected by and hosted on G2.com.

"The gold standard for private, secure, and bloat-free communication."

4.5/5

What do you like best about Signal?

The industry-standard end-to-end encryption is the biggest draw for me. Unlike other "secure" apps, Signal is open-source and operated by a non-profit, which removes the profit motive from my personal data. The UI is clean, the desktop sync is seamless, and the "disappearing messages" feature is handled much more intuitively than its competitors. Review collected by and hosted on G2.com.

What do you dislike about Signal?

The biggest hurdle remains the "network effect." It is often difficult to convince less tech-savvy clients or colleagues to switch over from WhatsApp or Telegram. Additionally, while the call quality has improved significantly, it can still be slightly less stable than some of the larger, resource-heavy enterprise platforms during low-bandwidth situations. Review collected by and hosted on G2.com.

What problems is Signal solving and how is that benefiting you?

Signal solves the problem of "data leakage" in professional communications. It allows me to discuss sensitive project details and share proprietary information with the peace of mind that no third party is harvesting that metadata. It has effectively replaced insecure SMS and less-private messaging apps for my most critical daily interactions. Review collected by and hosted on G2.com.

One thing I really appreciate is the privacy feature, which is something many other messenger apps are missing. Review collected by and hosted on G2.com.

"Secure, Simple, and a Lifesaver for My Growing Dog Sitting Business 🐾"

4.5/5

What do you like best about Signal?

As a small business owner just getting my private dog sitting company off the ground, Signal has been an absolute godsend. What I love most is the end-to-end encryption — it gives me and my clients peace of mind knowing our conversations stay between us. Whether I’m coordinating pet pickup times, sharing real-time updates and photos of their furry family members, or just checking in for last-minute changes, Signal makes communication seamless and ultra-private. No ads, no tracking, no unnecessary distractions — just clean, secure messaging. Review collected by and hosted on G2.com.

What do you dislike about Signal?

Honestly, not much to complain about. If I had to nitpick, it’s that Signal doesn’t offer business-specific tools like labels or scheduling features for messages. It’s a super secure messaging app, but not a full-fledged CRM. Still, for my purposes — direct, professional, and private communication — it does the job flawlessly. Review collected by and hosted on G2.com.

What problems is Signal solving and how is that benefiting you?

Trust is everything in the pet care world. My clients need to feel confident that when they’re away, their pets are in good hands — and Signal helps me build that trust. By using Signal for all communication, I can share timely updates, photos, and even short videos without worrying about privacy leaks or spam. It also keeps all my messaging in one place, which is especially helpful as I juggle multiple clients while building my reputation. Review collected by and hosted on G2.com.

"Unmatched Chat Privacy and Security"

5/5

What do you like best about Signal?

The security and privacy of your chats is essential. The fact that no one can access your information is crucial. It's simple to use and easy to add friends or create new groups. It's easy to send pictures or links. It's easy to go search for any links or photos added to a chat in a separate window. Review collected by and hosted on G2.com.

What do you dislike about Signal?

I dislike that I cannot screenshot a chat but understand it is due to the privacy of the software. Review collected by and hosted on G2.com.

"Easy to use, secure messaging app with steadily improving quality."

5/5

What do you like best about Signal?

Biggest upside is that it is secure. No big tech company breathing down my neck as I chat. No ads pulling me away or interrupting the conversation. Review collected by and hosted on G2.com.

What do you dislike about Signal?

Video chat is still a bit laggy and unreliable. It's probably the area that needs the most improvement. Group video chats in particular. Review collected by and hosted on G2.com.
