By default, iTalkBB App will place a call using your Wi-Fi connection. If you are not connected to a Wi-Fi network, you can choose to make call via "Mobile Minutes Call" or enable "Use 3G/4G Data" to make calls via your cellular carrier’s 3G/4G data network. (Carrier charges may apply over 3G/4G/LTE networks if you are roaming or have a limited data plan.) 6.What are the differences between "Wi-Fi Call", "Data Call", or "Mobile Minutes Call"? Wi-Fi Call or Data Call(for fast internet connections) : When you choose "Wi-Fi Call" as a primary option to make a call, the App will place all your calls over a Wi-Fi connection by default and this won't cost you any mobile minutes. When you enable "Use 3G/4G Data", calls will be connected using your mobile data network (might result in additional charges from your mobile carrier). Mobile Minutes Call (for slow internet connections) : Calls are connected using your mobile minutes from your mobile carrier. Best used when you have a poor internet connection. Calls will be made through an "iTalkBB Local Number", a domestic number, which will not be subject to any international calling rates through your mobile phone carrier. When you do not have access to a Wi-Fi connection, the App will notify you and ask you if you want to call via your mobile network and use your mobile minutes. 7.How do I make calls via my mobile carrier’s 3G/4G data network (Data Call)? First of all, please select "Wi-Fi Call" in the "Calling Preference" under "Settings". Then you can select to "Use 3G/4G Data" If you are not connected to a Wi-Fi network, you can choose to make calls via "Data Call" if you have cellular carrier’s 3G/4G data network. (Carrier charges may apply over 3G/4G/LTE networks if you are roaming or have a limited data plan.) 8.How to make international calls with iTalkBB App? It’s easy.
