Phonecall.app lets you make international calls to landlines and mobiles in 180+ countries directly from your browser. There's no app to install, no SIM card needed, and no account required to try it. You open phonecall.app, enter a phone number, and call. Rates are pay-as-you-go and shown before you dial, so you always see the cost upfront. The tool is positioned as a modern Skype alternative for digital nomads, expats, and remote workers. It's useful when you need to call a bank back home, confirm a hotel booking, deal with a visa appointment, or reach a landline that won't accept WhatsApp. Because it runs entirely in the browser, it works on any device including shared computers, work laptops, and tablets where you can't install software.
