Voice Calls Without Using Carrier Minutes
Internet voice calls use data or Wi-Fi instead of your plan's voice minutes, so they work even when you're out of minutes or have a weak cell signal.
How it differs
A traditional call travels over your carrier's voice network. An internet call travels as data, like any other web traffic, so it counts toward data rather than minutes.
One tool that works this way is GhostCall, a no-sign-up voice calling tool.
When it helps
It helps if you're on a prepaid plan with limited minutes, have strong Wi-Fi but poor cell signal at home, or travel and want to avoid roaming voice charges.
Limits
You need a data connection on both sides. Call quality follows your connection, and browser-to-browser tools can't reach regular phone numbers.
Make a call without creating an account
GhostCall lets you start a voice call from your browser with no sign-up and no phone number.
Common questions
How much data does a call use?
Voice uses far less than video, often tens of megabytes per hour, depending on the tool.
Does it work without Wi-Fi?
Yes, on mobile data, but watch your data cap.
Can I use it while roaming?
Data roaming charges may apply, so Wi-Fi is the safer choice abroad.
