While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Calloza lets you place international calls straight from a browser tab. No app to install, no SIM card, no roaming fees, and no monthly subscription. You add credit when you need it, dial the number, and pay only for the minutes you actually talk. We cover 150+ countries with per-minute rates published openly on our rates page, so you can check the price before you press the call button. If a call doesn't connect, you aren't charged. Voice runs over HD codecs and adapts to the connection you're on, which keeps things clear on slow Wi-Fi as well as on a wired desktop. Calls are encrypted end-to-end. Top-ups start small (a few dollars is enough to begin), payments go through Stripe, and your balance carries forward — nothing expires after 30 days, nothing renews behind your back. The product is built for two kinds of people: families staying in touch across borders, and small businesses that need to ring suppliers, customers, or remote teams abroad without paying carrier markup. It runs on Chrome, Safari, Firefox, and Edge, on phones and laptops, and your account works on every device you sign in to. Support is handled by people, not bots, around the clock. If a rate looks wrong, a call drops, or a top-up doesn't land, write in and a human will look at the actual call record and reply.
