I have family and friends with android. I don’t care they have android, but they refuse to use anything else to message. I have Telegram and Signal, and they just SMS/MMS
So you can’t stand iMessage because YOUR work blocked it? I don’t see the logic here at all. iMessage is way more secured than SMS/MMS.
I did not realize my dislike of iMessage would cause such a stir. Please allow me to attempt to clarify.
My displeasure of iMessage does not stem from the fact that my employer blocks it. My displeasure stems from the fact that, to my best immediate knowledge, there is no way to permanently deactivate iMessage from your Apple ID/iCloud account.
Some additional information may be helpful. Enterprise accounts with AT&T and Verizon have pooled data. So I have 2 GB of data each month on my account. If I don't use all of my data, the unused portion is used to cover someone else's data overage.
To conserve my employer's data, I connect my employer issued iPhone 6S+ to the WiFi network when I am at work. For security reasons, the network blocks third party messaging applications like iMessage.
I don't know for certain why they do this, but I believe it is because these messaging applications have the ability to transmit files. The files could potentially contain malicious software and would circumvent the content filters set up to block them.
Now if you log into your Apple ID/iCloud account with a new iOS device or your restore an iOS device to factory settings, iOS will automatically activate iMessage and register your Apple ID/iCloud e-mail address into iMessage. This activation will then sync with any of your iCloud contacts using iMessage and any texts they send will default to iMessage.
Getting this all untangled takes some time.
