@Sinistrahd, yes, we do think that may help. Can you test it out and let us know if there is any change or not?
2 years ago my husband and I both purchased LG X Charge phones when we switched to Xfinity Mobile. With both Data and Wi-Fi turned off, we could send MMS. (These phones were on Android IOS 7.0) A few months ago we bought my daughter a Moto e5, again with her Data and Wi-Fi turned off she can send MMS. (Her phone is on Android IOS 8.0.0) Everything was good.
My phone broke a few weeks ago, went to the store to buy another. LG X Charge was no longer available, so I purchased an LG K30. (New phone is on Android IOS 8.1.0) Got it all set up at the store, then on the way home (with Data turned off and no Wi-Fi) I tried to send a group text (MMS). Was surprised to see that the upper corner of my screen said "No connection" and the message would not send - below the text box it said "Waiting for connection." After a day of "playing around" with every setting I can find (and comparing them all to my husband's and daughter's phones), it does not appear to be a "settings" issue. I CANNOT send MMS with both Data and Wi-Fi off like I could with my old phone.
I have enabled both "Enable usage of cellular data in the background" and "Allow unrestricted data access when Data saver is on."
As recommended by some others, I tried the Messages+ app. Again, I was unable to send messages without data on.
Any further updates or solutions? I always kept my data turned off before. Now that I have it on all the time, my data usage has tripled even though I have turned off background data for every other app. This "inexpensive" phone is going to end up costing me an additional $12/month. I'd love to hear there's a way to fix it!!
Additionally - I have the same issue when using Textra. If Wi-Fi and Data are both off, it tries to send for awhile and then I get a "failed" message. I changed the carrier limit to 600 as was suggested. This made no difference.
I e-mailed LG about the problem, they said, "In some devices, mobile data connection may be enabled automatically when an MMS message is pending – thus, eliminating the need to manually enable Mobile Data. Since Multimedia Messaging System (MMS) services are provided directly by the carrier, you may also consider getting in touch with this if such automatic connection is one that will have to be provided to you as a setting."
This did not help me, but I wondered if there is a "setting" that Xfinity could provide to allow an override?
<Edited>. They just blocked my earlier reply with some error message. The average <Edited> user will turn on mobile data and be on their merry way. Not knowing they are charged data usage for a text message
Just switched from Verizon and bought a Galaxy10+ ($1000) same issue. CDant send or recieved MMS via WiFi which is a major problem for me... What messaging app did you switch too/ are you using? thanks
Just like everyone else I have recently run into this issue. I used to have unlimited data so never thought about it, switched to by the gig and turned off mobile data and can’t send simple pictures or group messages as they are considered mms, along with long messages. I know my S7 with xfinity mobile and before that with prepaid carriers and all the way back to flip phones you could send pictures via text data plan or not. It would be nice if we had options to get into the APN cause I’d venture it’s something there that xfinity changed when they got the update for pie or wherever it started happening at. I’m supposed to have unlimited text and yes pictures are part of text as that has been the precedent in my usage since phones could take pictures. Get this fixed.
ps I’m also may just be me not seeing time or date stamps from when people post....8/30/19 8 PM
SMS can be sent without cellular data active. However MMS will need cellular data active, even if you are on wifi. MMS messages are multimedia messages, but are also sent when sending group messages, any message with any accents or special formatting or emoticons, or messages longer than 140 characters.
The exception to this is if you have wifi calling active. If you have wifi calling active and you have the indicator XM Wi-Fi in the status banner where Xfinity Mobile usually is, then you can send MMS messages over wifi. You can force wifi calling active by making sure it is turned on in Settings - Phone and then putting the phone in airplane mode and turning on only wifi.
Remember, even though MMS text messaging requires cellular data to be turned on, if your are not on WiFi Calling, using data to send an MMS message does not count against your total.
