Galaxy S8 can not send/receive MMS or use mobile data

For nearly a week I have not been able to use my mobile data or send/receive MMS. I have tried resetting the phone, clearing caches, using the ##72786# reset, and resetting the network. Nothing is working and I am missing important messages from my employees and vendors. My account is completely up to date so there should be no reason I cannot use my mobile data. Ever since the merger I have had issues with my phone and service.

Sorry you're having troubles too. Read the other recent threads on this board there's a lot of it right now. It seems to have been created by the Android update on August 5th. there's a workaround to dial ##SCRTN# and reset the network settings on the phone. But for a lot of us that works for maybe an hour and then we have to do it again and again and again.

I am starting to shop for a different phone and carrier. This has been going on for a month and there is no end in sight. Makes me wonder if the new T-Mobile ownership is deciding to get rid of Boost altogether...


Hello- I am also going to start looking if it continues. It just stinks because I have to buy 2 new phones, sine my son is on my account. But I agree its not getting any better.  Should I try that ##SCRTN#? what will that do?


Yes by all means give it a try. It does not hurt anything. It will cause your phone to restart and it just finds the Boost network as though it were a new phone and then updates the background phone network stuff. But it will not remove any of your photos or files or anything else. The other thing that works for me is if I manually set the network mode to CDMA only which is just 3-g. If I do that the phone seems to work pretty well although obviously I'm not getting the LTE speed. But I just looked at prices for AT&T and Verizon and I'm still paying a lot less on Boost then I would be on them. So maybe I will just learn to live with 3-g speed for those infrequent times that I can't use Wi-Fi.

Hi there! Sorry for the delayed response. Support is available from 6 am - 10 pm CST Monday - Friday, and from 6 am - 9 pm CST on weekends. 


Sorry to hear that you are experiencing this. Could you please tell us if your Samsung S8 phone is showing the VoLTE option? You should be able to see it on Settings> Connections> Mobile networks.


Thanks for the reply.

I do NOT see the word "VoLTE" anywhere in the Mobile Network menu or in any submenus there.

Thank you. Your phone uses the mobile data to send MMS messages. Your phone should automatically use the mobile data to send the MMS even when connected to WiFi. We would like to access your account to verify the network settings. Please send us a private message to assist you. To send a Private Message, click my username or picture, then click "send this user a private message".


Just for anyone who reads this, I did PM with the Social Care reps.  While I am appreciative of their intentions, the suggested solution was to do the ##72786# again.


So I did, but that still has not fixed the problem or changed anything that I can see.


So for now I have switched my phone to "CDMA" network mode, which seems to make the phone function correctly, but restricts it to only the 3G network.   Until a better fix is offered.


Yet you can send MMS to others with WiFi on if they're in the boost network.

Hi. Thanks for contact us. Some devices are manufactured to receive and send Multimedia Messages (MMS) while connected directly to the carrier's network. If you have any other question or concern, feel free to reply.


FWIW I have switched to Cricket Wireless with the same phone and am very pleased so far. Cricket is actually slightly cheaper with a dual line discount than Boost but I do not get the free 10 GB of hotspot. So it's a trade-off. But I can send MMS messages with Wi-Fi on again!
