Features & Capabilities

OneSim VoIP offers OneSimCard customers a cost-effective way to make and receive international calls on iPhones and iPads. Users need a quality Internet connection—Wi-Fi, 3G, 4G, or LTE—and a VoIP-enabled Personal Extra Number (PEN) activated with OneSimCard. Calls placed through the VoIP network are generally much more affordable than standard international roaming rates.

The app also supports texting, allowing users to send and receive SMS to and from US and Canadian mobile phones via Wi-Fi or mobile data at reduced rates. While the app does not require a OneSimCard SIM installed on the device, users must have a OneSimCard account with VoIP and SMS enabled PEN. Initial setup is done through the OneSimCard online account. Note that call quality depends on the internet connection and may not always match the quality of traditional roaming networks.
