Feature Comparison
Caller
Browser-Based, Zero-Install Magic
Ditch the downloads forever. Caller runs directly in your web browser, which means you can start calling from your laptop, desktop, or even your tablet in literal seconds. No more waiting for apps to update or fighting with system permissions. It's as easy as opening a new tab. This also means you're never tied to a single device—your calling power goes wherever your browser does.
Pay-As-You-Go, No-Subscription Freedom
This is the anti-contract. You only pay for the call minutes you actually use, with rates starting from an almost-too-good-to-be-true $0.02/min. There are zero monthly fees, no hidden charges, and no sneaky subscriptions that auto-renew. You simply add credit to your account (any amount you want) and it sits there until you need it, never expiring. Total financial clarity and control.
Global Reach with Crystal Clear HD Voice
Caller isn't playing around with coverage. You get access to over 200 countries worldwide, hitting both landlines and mobile phones. And these aren't scratchy, laggy connections—we're talking enterprise-grade infrastructure pumping out HD voice quality so clear, you'll forget you're on an international call. It's the audio equivalent of switching from standard def to 4K.
Dedicated Phone Numbers On-Demand
Level up your pro game by snagging your own dedicated phone number. Choose from local numbers in places like the US or UK, toll-free lines, or mobile numbers. Use it as your caller ID to look legit, or give it out as your business contact. Numbers start from $1.99/month and activate instantly, no paperwork or waiting period required.

Caller
The Globetrotting Freelancer or Digital Nomad
You're working from Bali but your biggest client is in Toronto. Instead of racking up insane roaming charges or relying on flaky cafe Wi-Fi for a VoIP app, you just hop on UseCaller in your browser. You get a professional connection to discuss the project, pay pennies on the dollar for the call, and keep your business moving smoothly without any geographic headaches.

Frequently Asked Questions
Caller FAQ
Do I really not need to download anything?
Nope, not a single thing! Caller is 100% browser-based. As long as you have a modern web browser (like Chrome, Safari, or Firefox) and an internet connection, you're good to go. Just head to the website, sign in, and start calling. It's that easy. No software to install, no updates to manage.
How does the pricing actually work? Are there hidden fees?
It's super straightforward, we promise. You pay only for the calls you complete. First, you add funds (as little or as much as you want) to your account balance. Then, when you make a call, the cost per minute is deducted from that balance. Rates start at $0.02/min and are clearly listed. There are NO monthly subscriptions, NO minimum fees, and NO hidden charges. You only pay for talk time.
Can I get my own phone number for caller ID?
Absolutely! You can rent a dedicated phone number from UseCaller (starting from $1.99/month) and use it as your outbound caller ID. This is perfect for freelancers or small businesses who want to display a professional local number when calling clients internationally, instead of a random or blocked ID.
What if I don't use all my account credit?
Your credit just chills in your account until you need it. It never expires. So you can top up $20 and use it over weeks or months—whatever works for you. There's no "use it or lose it" policy here. You're in complete control of your balance and your spending.
