No longer able to sent myself text messages for check in messages. Icon isn't a phone by my number anymore - it's a message icon.

What the title says - up until very recently, when I sent one of my pre-set check ins (just switched them over to the newer check in messages) and while I can finally get it to go to my email address, I can't send a check in to my cell as a text message. I noticed that the icon next to my phone number is a message icon instead of a phone icon - so did something change to prevent sending of a message to SMS when it's the account holder's number? It's still successfully texting my other contacts for those presets.
