If it was that big a deal for you, why would you use a phone OS by that same company?
SMS is hot garbage:
The first “S” stands for short. If your message is over 160 characters, you are sending multiple messages. The implementation of SMS is a hack on the carrier network in the first place, and joining multiple messages, particularly across carriers is a complication to this hack. Sure, 99.99% of messages are delivered just fine. But if the message doesn’t arrive for some reason, there’s no acknowledgement of this. The recipient just doesn’t get it.
SMS is easy to spoof. If I have even basic carrier access, I can send a message to your dad from your number.
I can initiate a number port on your number, and while that port request will likely fail, it’s possible that I can receive messages that were destined for you in the short term.
