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. 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.
