Wi-Fi calling & text

Yes, you can use Wi-Fi to make international calls. There are two ways how this is done. 
• You have to enable Wi-Fi calling on your device and use it to call the international number. Note that if your Lyca Mobile prepaid plan doesn’t have international calling benefits to the recipient’s country, you will be charged the usual pay-as-you-go rates. 
• You can use a VoIP (Voice over Internet Protocol) app, like WhatsApp, to make audio and video calls within and outside the US. Calls made using such apps consume a lot of data. It’s recommended to purchase an unlimited data plan to ensure you have sufficient data allowance for VoIP calling and other internet uses.
