Just an update: I’m apparently missing longer texts as well, albeit intermittently. In the last two weeks I’ve had someone send longer text messages and they didn’t go through (and then they showed them to me in person). I called the carrier and again, they are confirming that the text is arriving to and being dispatched from their server. I’m guessing this might be an MMS issue?? Of course, if I send myself a long message right now from a secondary number, it will come through no problem.
For my part, I am awaiting a new SIM card to switch carriers and see if that changes anything (TMobile USA–any support or feedback from others?).
Struggling with these basic texting issues, Mudita. Any help would be appreciated.
@wander When text go over 160 characters they sometimes get split up into 2 segments OR they just get converted into MMS.
It usually goes like this:
1-160 character(s) = 1 SMS segment
161-306 characters = 2 SMS segments
Do you have MMS enabled on your device?
If I go to “Settings” → “Network and Internet” → “Mobile Network”, it only shows “Mobile data” and “Roaming”, both of which are on. I don’t have the “MMS messages” option, even if I push the “Advanced” button on the bottom.
I think that particular toggle appears when the first one is off.
@wander 1st dialog on the photo that Urszula has posted appears in SMS app (click 3 line icon near Pen icon).
And like @buiosu said that toggle appears when Mobile Data is off. The 2nd photo is from the Network & Internet / Mobile network.
Hmm. That’s odd. let me go back to the team with this. It might be a carrier issue.
There was on user whose problem ended up that their phone plan did not include MMS messages. I’m not saying this is your issue, but I just want to make sure we cover all bases.
@buiosu and @gezimos are correct – I turned the “Mobile data” toggle off and the “MMS messages” toggle appeared. I’ve turned “Mobile data” off and “MMS messages” on for now as you showed in your photo @urszula .
Although I’m curious–are they mutually exclusive? Theoretically, if I have “Mobile data” ON, shouldn’t I also receive MMS messages?
Thank you all for your continued help and troubleshooting with me.
