SMS vs imessage
Why do some messages show delivered but some show sent as text to the same number? It seems very random when this happens. Sometimes it’s back to back texts
If it is the same number where sometimes the messages sent are blue and other times they are green, then the person you send them to may have Cellular Data turned off. The blue messages require an internet connection and if they have Cellular Data turned off, your messages will only be sent using SMS and will show up green on your end.
The same would be true on your end as well. If you do not have an internet connection, then your messages will only be sent as SMS and appear green.
