LG-D851 No mobile data after usb tethering - G3 Q&A, Help & Troubleshooting

I have a T-Mobile branded LG G3 on T-Mobile's network. I was using usb tethering while testing a mother board about a week ago, and after disconnecting my mobile data connection wouldn't work. I got it working after a couple of days by partially putting in a dummy apn setting. When I say a dummy apn, I mean that I only gave an APN name, and "fast.t" for the APN, not even the full address. When switching to this apn, my lte connection immediately popped up and things seemed fine. But after a few days I realized that I'm unable to send mms messages. Text messages have worked, but no mms. I've tried entering the complete apn settings, and now I have no data connection at all. I've tried resetting network connections, and that didn't help either.When resetting, I have the default T-Mobile LTE apn, and another EDGE MMS apn, but the EDGE MMS apn has no way to select it. It's just there, and neither allow modifications. I'm running 6.0 stock, rooted, and TWRP recovery. I've made no system modifications beyond root and recovery. Anyone know of some suggestions? I haven't come across any apn issues resembling my specific issue from other users.

Visual Voicemail only with LTE APN, not Phone

Don't have LTE, so I created an APN for phone, gives me faster speeds with ATT and lets me use Onlive (blocked using the original APN). Noticed however visual voicemail only works with the LTE APN. any way to add it to my custom one?
Don't have a response to your question but I'm curious how you got the new APN to stick? On mine when I created another APN but it just keeps on defaulting to the "pta" APN.
My understanding visual voice mail is exclusively for LTE network. In fact, if you switch to LTE plan and go back to regular plan, you might endup with disabled voice mail.

I have no problem adding new APN and use it...
I wasn't aware there was a separate LTE plan?
That is strange. I wonder why I cannot set up an additional APN to connect to. Whenever it's selected, I can watch it get switched back after a few seconds...
Yeah, basically it's the same plan just has LTE in it's name.
If you have SQLite Edit (or something similar), you could try alter the APN manually.

I had the same issue with the phone APN not sticking. I followed the instructions from a thread in the Skyrocket forum about throttling that said to use phone for the APN name, internet for the APN type and leave everything else blank or default. How I ended up solving it was using the MMSC, MMS proxy, MMS port, and APN type entries from the pta APN and using them in the phone APN and after that phone APN would stick.
Also, I too am unable to get Visual Voicemail on the phone APN.
Thanks! I can't believe I didnt think about trying that. I just created the phone APN with the same settings as PTA and it works. I'm back on regular HSPA+ speeds since I'm not in an LTE area. For what its worth, visual voicemail works just fine for me.
Evening-
I too had some issues with the VVM not working and couldn't figure out why...even tried to use YouMail with no luck and finally logged into my account and reset the password for my V-Mail. I then re-set up the stock ATT VVM, deleted the forwarding YouMail installs and everything worked like a charm again.
I too setup the alternative APN (not in the LTE Market) and it stuck just fine...maybe try resetting the password/pin and see if that works. Good luck!

[Q] How can I get my network reliability AND the ability to send and receive MMS?

I have a Rogers Galaxy Note 2 on the Telus network unlocked using the hardware method posted here previously. Since the unlock I've had some weird data inconsistencies. It wouldn't allow me to do a speedtest; if I refreshed my gmail manually, it would say no connection but if i pressed it an extra time or two, it would work; and scrolling through facebook pictures it would tell me the network was unavailable but the pictures would load anyway. I accepted this as a subtle difference between the two phones.
I couldn't sleep last night and decided to play around with the APN settings. I changed all my APNs to have the bearer "LTE" and to my surprise, I could do speedtests! I thought I had cured everything. But today, my girlfriend tried to send me an MMS, but I couldn't see it at all; if I turned the bearers to unspecified, MMSs worked. I've tried a couple combinations of the two to no avail.
I'm currently using the APN settings given to me by the app Tweakked with the "Unspecified" bearer and MMS works but the data inconsistencies are still there.
Please help. I can tell the hardware functions with Telus, I just need to know if I need to do anything else to get it working smoothly. Thanks in advance!

Simple Talk APN settings...mms problems

So I just left tmobile this morning and ported my number to straight talk (using an At&T micro sim card). I am having issues getting mms to work. I tried the APN settings from straight talks website but nothing worked (no data, no mms). I searched a bunch of forums and found an APN setting that gets me data, but no mms. Anyone else have the Tmobile Samsung Galaxy S3 (non LTE) that switched to Straight Talk At&t sim card and have everything working?
Thanks in advance.
Is your Data Connection working ? Ask Straighttalk for their correct APN Settings. They do control MMS.

I have data working using apn wap.tracfone
On simply talks website the apn settings don't work, no data or mms
Wap is a very ancient APN. Please call customer Service for correct settings.

I need your S4 data T-Mobile settings

I have a Sprint L720 Galaxy S4 that I am currently using with Metro PCS/T-Mobile. I have the correct APN settings, I can make and receive calls just fine. I can send texts and MMS just fine and receive texts as well. I can not receive MMS messages or texts with picture attachments.
I looked in the ##DATA# menu or ##3282# menu as I have my MSL number. If anybody here has used the L720 or nearly any fairly new Android with T-Mobile/MetroPCS can you please give me your working settings from the data menu?
I looked through the entire data menu and it is filled with Sprint.com this and sprint/mms/server that etc. I tried changing the most obvious things to T-Mobile's settings, but I know I am missing the crucial settings to allow me to send and receive texts with photo attachments. I tried the METROPCS fix here in the forums for the L720, but the files give errors when installing. I am certain that manually entering the settings from someone else's phone will work. There are a lot of settings in the ##DATA# menu, but it would take maybe five minutes to copy them down.
I would really appreciate it if anyone could give me their working info. T-Mobile said they simply do not have time to look those up as the data menu is too specific. The phones in the stores are not rooted not do they have the dialer app installed to get me to the data menu.
Thank you very much.

All you need are a few settings. Name the connection T-Mobile
Under APN input fast.tmobile.com
MMC 310
MNC 260
Everything else should be automatically filled in. Just input those settings and you're now able to connect to T-Mobiles LTE data.

I sincerely appreciate your response but I have since learned that the Sprint motherboard simply can not use all of the T-Mobile frequencies for LTE data. I was getting H+ which was not bad but I was hoping for more than the board was capable of.

My apologies was not reading carefully. Sprint's Mobile APN settings are different:

MMS problems Lineageos 15.1 20190423 starlte

Hi,
I'm in Australia, new Samsung S9 using Boost mobile (Telstra reseller). Out of the box I flashed Lineage and twrp recovery, as well as a gapps pack. Everything works as it should except MMS. I've confirmed APN settings match the telco as specified, although I've noticed there are 2 APNs for each of internet and MMS, in the default APN settings.
When I receive an MMS, my data connection breaks and the MMS gets stuck "downloading" before it fails, and the only way I can fix my data connection is to delete the MMS, then turn mobile data off and on again.
Any ideas?
TIA
Dan
So... Anyone having the same problem? Coz it sucks. MMS is a basic function that surely is not difficult to solve..
