Added (1). Also i installed text now

My phone is deactivated and it sucks. You can't call but you can get an app called textfree which lets u call and text anyone as long as you have Wi-Fi. A another person doesn't need the app. But you also need to watch videos to earn minutes to call or you can buy them. You can still iMessage people who have an iPhone. But what really sucks is you don't pick up Wi-Fi anywhere you have to connect to it. Home Wi-Fi and hotspots like optimum work fine.
