I run with a local fire company and we just added I-pads to the front of the trucks for internet capability and for use of the Active 911 app. What I'm trying to do is set up some type of texting for each truck so we are able to talk to one of the other trucks. As of now we have 12 I-pads that are all on the same I-cloud. But I would like to be able to use I-message to be able to message each truck individually. Do I need to set up a different I-cloud account for each individual truck, and if I'm logged into the Imessage account will I still get the updates that are updated throughout on the dept. wide Icloud account.
