[HTC 10 ROMs, Kernels, Recoveries, & Other Developm] Clemenator:
Hey all I can't seem to send or receive MMS's it say error failed when sending and has download option when receiving but times out, Telstra has done a reset on my sim but still no go, Phone is set to auto DL mms but does not this was not a problem on the last version of lineage I was on from around 4 months ago and I only noticed the problem now on lineage-16.0-20190519-UNOFFICIAL-pme that I installed about 1 week or so ago when I tried to DL a mms my sister sent me.

The phone is set to auto DL mms all settings are correct Telstra and I just can't figure out why it is not working, when I installed lineage-16.0-20190519-UNOFFICIAL-pme I wiped everything to the point only the bootloader was left on my phone and I used my PC to flash the latest twrp version 3.3.0 installed rom and gapps.

Everything else works, calls, LTE, sms, apps ect just not MMS's, I did use the search function on this forum before writing this post however nothing like my problem came up so at this stage with telstra at a loss and me at a loss I have no other option but to ask you guys for help, I have also cleared the cache of the messaging app and the dalvik cache and standard cache in twrp but still nothing!

Update so I got onto telstra again and they got me to put in the APN settings manually and it still will not send MMS or receive MMS :( The only thing that has changed since it was working is I updated from 4 months ago lineage to lineage-16.0-20190519-UNOFFICIAL-pme and did a full wipe of my whole phone, I can send pics via kik app just not via the phone I even tried using a different message app called textra but same problem!

Below is a transcript of everything we tried

Ben: Was on here earlier tonight and guy reset my sim to no avail so will save you the time, pretty sure I just need correct APN settings

Ian Rey: I'm sorry for the delay. I'll be right with you.

Ian Rey: Allright. I'm looking at the account.

Ben: I am trying to send you a pic of the settings I manually put in however your chat won't seem to let me

Ian Rey: I see. May I know the error message when you send?

Ben: Not sent tap to try again and when trying to DL one sent to me there is a DL button but it time's out and does not DL

Ben: Phone is set to auto DL mms but it does not

Ian Rey: Are you trying to send it in local number?

Ben: HTC 10 Android 9, was working a month or so ago when I sent one, as I said I updated my rom and believe it has forgot the APN settings

Ben: Yeah to myself

Ben: And my sister send me 3 pics tonight from her mobile this is when I realised the issue

Ian Rey: You also cannot receive mms?

Ben: Correct

Ian Rey: Allright. Stay online. I will check the apn

Ben: It shows when sending it is using internet as I have a traffic monitor but just fails to send, so it is trying

Ian Rey: Can you try it again?

Ian Rey: I refresh your network

Ben: Same failed to send tap to try again

Ben: Sms, lte+ and calls work fine just not mms

Ben: I can send pics via kik app just not via phone itself

Ian Rey: Have you check if the mobile data is on?

Ben: Yes it is on it is how we are chatting now

Ben: Everything else works eg, playstore, browser, apps, sms, calls, ect

Ian Rey: I see. Have you recently make changes on the APN setting?

Ben: I still think we should manually put in the APN settings into my phone and see if that fixes it

Ben: Yes I did once I realised mms was not working I followed the telstra APN settings

Ian Rey: Yes. I also added the Apn's here seems not still working. If it does not work manually in your end. I higly recommend you go to the nearest telstra shop to have it personally change the setting so it would be accurate.

Ian Rey: Are you still there?

Ben: Yeah

Ben: Just waiting for the settings I should put in manually from you

Ian Rey: I see. No worries.

Ben: I only changed the telstra wap settings not the telstra mms settings fyi
