Not possible without some sort of data or Wifi connection.
If there's an Android in the mix without data they'll need WiFi and you'll both need a 3rd party app like WhatsApp. In any scenario both parties will need either a data connection or a WiFi connection.
Close, but not quite right.
iMessage sends messages via SMS when texting a non iPhone user. If you are on WiFi only, without a carrier link, you cannot iMessage non iMessage users.
When you are on WiFi, and you have a carrier link (if that’s the correct term) you can text non iMessage users, it goes through the carrier as an SMS or MMS.
AT&T has international WiFi calling. I use it. I am in Nigeria no where near an AT&T tower with my US SIM card, airplane mode, WiFi on, and when WiFi calling is engaged, I can use the phone just like I was in the US. WiFi calling not engaged, then it’s only iMessage to iMessage, or what’s app. iMessages to android users fail to send.
