OneSim VoIP provides OneSimCard customers with an even less expensive way to make and receive international calls on their iPhone mobile phones or iPads. To use OneSim VoIP, users must have a good quality Wi-Fi, 3G, 4G or LTE Internet connection and a VoIP-enabled Personal Extra Number (PEN) activated with OneSimCard. When making an outgoing call, OneSimCard users can select the way the call will be made – either through the OneSimCard international SIM card or OneSimCard VoIP network. Calls made over the VoIP network are generally much less expensive than OneSimCard’s standard international roaming rates. Incoming calls made to the PEN will be received through low-cost VoIP if the OneSimCard phone and OneSim VoIP app are registered on the Internet. Otherwise, the call will be sent the usual way to the phone through the international SIM card. The newer version 2 of the app adds the texting feature and allows the sending and receiving texts (SMS) to and from US and Canada mobile phones over Wi-Fi or mobile data at much lower rates than regular SMS sent and received over the roaming network. The app does not require having a OneSimCard SIM installed in the phone, but it does require having a OneSimCard account and a VOIP and SMS enabled PEN. Initial settings for the app are available in the “My SIM Cards” menu of the OneSimCard online account. When in the My SIM Cards menu, select the SIM (if there are more than one on your account) and then click on the Create VoIP Account link. This will create a OneSimCard VoIP account and provide you with a link with Settings information for your iPhone or iPad. Important: Connection quality of the calls made using OneSim VoIP option over the Internet will only be as good as the quality of the Internet connection. Please be advised that in many cases this kind of connection quality is inferior to the connection quality made through the OneSimCard international SIM card roaming network.
