They all do now. MMS, iMessage, any other messaging app, also require an active data connection to actually reach your phone.
The only thing that did not require an active data connection in place is real SMS, with all its limitations.
That's why we still rely on SMS in rural Canada, most of the time our phones are too far from the tower for LTE to establish a link. Most attempts to use modern SMS replacements have ended in unreliable messaging and me having to support all my neighbours in shutting off the messaging support in their apps so they can use reliable SMS.
I run Pulse SMS on my phone to ensure my SMS is always SMS and will be delivered. Unfortunately I see no path away from reliance on 3G/HSPA as the eye closes on LTE after about 25km, resulting in "bars" on the phone but no ability to transfer data.
3G has been shut off and 2G will be going down in weeks. SMS won't work without LTE or 5G soon.
Just curious, is there a specific reason you keep data and wifi off unless you're using them?
Have you ever recorded WiFi traffic on any device? It's pretty crazy the amount of packets being transfered and received at any given moment
So? Do you personally have to send out these packets by mail?
I've noticed this in the mountains as well, even though I don't think I'm that far from the tower I guess the normal cell signal bounces off the rock and stays readable but the data does not. Usually pretty close that they go out but as I go into a valley/ravine/hollow/canyon I do lose data first, while I still have 3/5 bars.
If you have Internet, you can also just use Signal. No need for RCS.
