imessage

iMessage is carrier specific service. You need to have data plan loaded on to your plan. Contact them and ask of internet plan and then activate.
iMessage and FaceTime uses internet data. If your network is bad the then you may have difficulty is sending iMessage and call on Face Time
It is always better to use Wifi during FaceTime
Once the iMessage is activated then FaceTime will automatically get activated
