As answered by people managing FirsTech and Telhey.
Telhey's answer:
TelHey lets you make international calls to real mobile phones and landlines directly from your web browser. There is no app to download, no phone number required, and no subscription. Just open TelHey, enter a number, and call.
Telhey's answer:
TelHey is built for simple, on-demand international calling. You can call directly from your computer or phone browser without installing an app. It uses prepaid credits with pay-as-you-go rates, so there are no subscriptions or recurring fees. It is especially useful when you need to quickly call a bank, airline, hotel, business, or someone abroad.
Telhey's answer:
TelHey is designed for travelers, expats, international students, digital nomads, and anyone who occasionally needs to call a real phone number abroad. It is particularly useful for people using data-only eSIMs and those who need to contact international banks, airlines, hotels, businesses, or landlines.
Telhey's answer:
TelHey was created to make international calling simple again. Many people only need to make an occasional international call, but traditional calling can be expensive and many VoIP services require an app, subscription, or phone number. TelHey provides a simpler alternative: open the website, add credits, enter a phone number, and call directly from your browser.
Telhey's answer:
TelHey is built with Nuxt, Vue, WebRTC, Cloudflare, and Telnyx. WebRTC enables real-time voice calling directly from modern web browsers, while Telnyx provides the telecommunications infrastructure for connecting calls to mobile and landline networks worldwide.
Telhey's answer:
TelHey is primarily used by individual travelers and people who need an easy way to make international calls. We do not currently publish individual customer names.
