Unlike SMS text messages, but like texting apps, RCS and iMessage use your data connection. So if you have a poor data connection, those features won't work very well. Chances are restarting your phone and/or Wi-Fi router will also fix the problem.
SMS is unencrypted and therefore less secure. But unless you're plotting to overthrow the government, no one's going to care.

I first figured out the problem because I was trying to text my shopping list from my hobby phone to my work phone and wouldn’t go through . spent hours trying to figure it out.
I thought someone was ignoring me last night so I called and he was not receiving my messages. He turned off RCS messaging and we Had a lovely two hour session :-)
