Communication v2.4.19
Virtual second phone number app for work and travel. Get a US/UK number over Wi-Fi, separate personal and business calls. Good call quality, group video, quiet hours. But limited to ~10 countries, SMS verification issues.
After years of juggling two SIM cards and a burner phone for freelance contracts, I finally tried Call.com: 2nd Phone Number App. It gives you a real virtual number that works over Wi-Fi or mobile data on any device — no extra SIM required. I set up a US number within minutes, and immediately noticed how cleanly it separated my client calls from my personal messages. The core value is simple: one app, one second line, no hardware hassle.
Voice call quality surprised me — even on a shaky hotel Wi-Fi in Mexico, calls to the UK were clear and rarely dropped. Sending SMS from the app feels snappy, and I use the bulk SMS feature to notify multiple clients about schedule changes. Group video calls with up to ten people are free between Call.com users, which my small remote team adopted for weekly check-ins. The shared company credit and ability to reassign numbers in one click saved us from administrative overhead. I also appreciate the personalized voicemail per number — I have one for work, one for my side hustle, each with a different greeting.
Call forwarding is straightforward: I forward my US number to my local SIM when I’m home, and switch it off when I’m abroad to avoid roaming. The quiet hours feature blocks calls after 9 PM automatically. These aren’t flashy, but they reduce mental load.
Not everything is rosy. First, the virtual number selection is limited to about ten countries — I live in Japan and still can’t get a local Tokyo number. For freelancers in Asia or Africa, this app may not cover your needs yet. Second, international calling rates, while transparent and fair, aren’t as cheap as some VoIP‑only services. I still pay a few cents per minute to landlines in certain countries. Third, the app occasionally logs me out on my tablet when I switch Wi‑Fi networks, which forces a re‑login mid‑call. That’s annoying in a hurry.
Also, if you rely on SMS for two‑factor authentication from banks or services, some providers flag virtual numbers as VoIP and refuse to send codes. I had to keep my primary SIM for those.
If you’re a digital nomad needing a stable US or UK number for client calls, or a property manager who wants a separate line for each listing, Call.com is solid. It also works as a cheap way to turn a tablet into a phone. But if you need a number in less‑served regions, or you depend on receiving SMS verification codes from strict institutions, you’ll hit friction. The app suits freelancers, remote teams, and international travelers who understand its geographic limits.
I’ve used it for six months across three continents. For my freelance writing business, the second phone number app replaced my old dual‑SIM setup completely. Call.com isn’t perfect, but it’s a practical tool when you know what you’re getting into.
