Although the AOW Global Data SIM is a data-only service, you can use a VoIP (voice over IP) app like Facebook Messenger to make calls and send messages to your friends on Facebook.
You can use Facebook Messenger with any smartphone or tablet with an AOW Global Data SIM inserted. To use it, all you need to do is download the Facebook Messenger app. You can login with your regular Facebook credentials or create a new account on the app.
To make calls, tap Calls and then tap the contact you want to call. You can either video or audio call your contacts.
To send messages, tap Home and tap the new message icon in the top right corner of the screen. Alternatively, you can tap People and click on the person you’d like to message.
