Calling Cards

VoIP Services
Voice over Internet Protocol (VoIP) services allow you to call US landline and mobile numbers over the internet instead of using a regular phone line. Since VoIP also offers call management features such as call forwarding, call recording, voicemail, and analytics, they’re especially useful for business calls.
Social Media Apps
Social media apps like WhatsApp, Messenger, Telegram, and Viber let you make free voice or video calls over Wi-Fi or mobile data. They are easy to use for personal calls as there is no complex setup, and a subscription is not required. However, both callers and receivers must use the same app and have a stable internet connection to make a successful call.
Wi-Fi Calling
Wi-Fi calling is a built-in smartphone feature that routes calls through a Wi-Fi network instead of a cellular signal. It uses the phone’s regular dialer and existing number, so no separate app or account is needed. However, international calls may still incur charges, depending on your carrier.
