[Q] APN question - "bearer" field & APN Backup & Restore Bug - General Questions and Answers

The bearer field of an APN indicates if the APN is for LTE (14), eHRPD (13), or Unspecified.
One thing I have noticed is that APN Backup & Restore doesn't save/restore the "bearer" field. As a result all APNs produced by this app are of bear type "Unspecified". As far as I can tell an Unspecified bearer can be used for both LTE & eHRPD.
I'd like to know if there is any reason (i.e. improved performance) to specify the bearer type.
Also, would it be better to keep 2 APNs (one with bearer=LTE and one with bearer=eHRPD), or just have a single APN with bearer=Unspecified?

Default APNs

Ok, I accidentally deleted one of my APNs the other day and now all I have is the default epc.tmobile.com. Does anybody know what the other APN is?
Normally you'd have two APNs in a completely stock phone labelled "T-Mobile Data" and "T-Mobile MMS"
Both of them point to epc.tmobile.com, the only difference is "T-Mobile MMS" has the "MMSC" field filled in with "http://mms.msg.eng.t-mobile.com/mms/wapenc" and has the APN type set to "mms".
You don't really need two different sets of settings for MMS though. You can just set the MMSC to "http://mms.msg.eng.t-mobile.com/mms/wapenc" in the one APN you have already and it should work. Try setting it and send an MMS to yourself and see if it works.

[Q] Avatar 4.2.2 Rom LTE APN issues

I have an S-OFF ATT HOX. SuperCID. Installed the Avatar 4.2.2 rom. Works great! Snappy, and pretty! Only problem is I was only able to get 4G speeds. After a 30 min conversation with ATT to confirm there were no issues on their end, I looked at the APN settings for PTA. The APN settings were incomplete.
Normally the APN type has default,mms,supl and hipri but my installs (3x) never included. I attempted to add the hipri to the APN and even create a new APN, but the changes would never save.
Any thoughts?
Is the APN locked from being edited? Try just making a new APN with the correct settings.
Avata 4.2.2 APN woes
Its not locked. I can get into the existing 6 APNs and create a new one, but there is no save button on a new APN or existing APN. But I guess by definition means it is locked. I speculated just pressing back auto saved the entered settings but alas, no LTE goodness
Weird. I've seen where the APN is locked from editing (Save button is grayed out) such as the default APN on the AT&T stock ROM. But even then, you can create a new APN and save it. Never seen where it locked you out from editing and saving altogether.

[HELP] T-Mobile data - bad Nexus 5 radio or the wrong APN setting?

I have the Nexus 7 LTE (2013) and I use T-Mobile pay-as-you data ($30 / month). I have great data connection, even when my N7 only shows 1 bar and I still get at least 1 Mbps download. No issue even when I am in subway train. This drove me to get T-Mobile Simple Choice Plan for my whole family.
I got the Nexus 5 straight from Google and the experience has been the exact opposite! I can get full bar, LTE icon showing up and... no data transmission. Sometimes I get good data, sometimes I don't.
I looked at the APN settings for both the N5 and N7 and they're slightly different, so I am wondering if I have the right settings. I don't know if I have a Nexus 5 with bad radio or just the wrong setting - Can anyone assist?
Here's what I have:
I. Number of APN:
Nexus 7: T-Mobile US LTE (fast.tmobile.com)
Nexus 5: there are 3 of them:
- MetroPCS,
- T-Mobile GPRS (blank)
- T-Mobile GPRS (fast.tmobile.com) --> selected
II. APN settings:
Blue = Nexus 7
Red = Nexus 5
Green = same settings for both devices

Use ipv4 on Nexus 5! Apply and reboot, test, report back.
Yeah I was gonna say the same as it seems speeds limited on IPV6 for your Nexus 5.

Fix for MMS issues on Pixel 2 on T-Mobile while connected to certain Wi-Fi networks

This was also posted as a reply on the Pixel 2 XL Q&A forum here and I figured other T-Mobile Pixel 2 users would find this useful since this fix works on both the Pixel 2 and Pixel 2 XL.
Situation
My wife was unable to send MMSs on T-Mobile with her Pixel 2. Finally realized it had to do when connected to Wi-Fi, but only when connected to the EAP Wi-Fi at work. Since we work for the same company, I tested with my Pixel 2 XL and it is happening to me too. It works fine at home on our Wi-Fi and on the mobile network, but not when we are on our work's Wi-Fi. I can disable Wi-Fi at work and the MMS sends. Both phones have the same dysfunction. I normally use Google Voice and I never receive MMSs directly to my phone and had not noticed the issue up to this point.
I did a test where I added my Google Voice number and my wife's number in a group message with my phone's number and tested connecting on Wi-Fi, mobile network, and work Wi-Fi and every time we are on the work's Wi-Fi, MMSs fail to send or receive. I know it is happening to only Pixel 2s and no one else because my wife's previous phone, a T-Mobile Galaxy S7, worked fine on any network to send/receive MMSs. I have reset network settings and APN settings back to default, no change. From what research on the issue I could find, people were changing APN settings. Looking at the APN settings, I realized the two T-Mobile MMS listings have the APN listed as "TMUS," whereas the default APN is listed as "fast.t-mobile.com." Since "TMUS" is not a valid domain name, I changed the first T-Mobile MMS APN to fast.t-mobile.com and MMS started working on the work's Wi-Fi. I reset my APN settings back to default and it stopped working on my work's Wi-Fi again (as expected). I thought that I should leave the default APNs alone, just in case, and decided to create a third T-Mobile MMS APN with fast.t-mobile.com as the APN. This third T-Mobile MMS APN somehow allows MMSs to work on the company's Wi-Fi.
Fix
This fix seems to be the least amount of work and is very easily undone.
Go to Settings > Network & Internet > Mobile network > Access Point Names.
Tap on the 3 dot menu at the upper-right and select "Reset to default."
Create a new APN with the following settings:
Name: T-Mobile MMS
APN: fast.t-mobile.com
Proxy, Port, Username, Password, and Server: Not Set
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc (When typing this in, make sure auto correct doesn't change anything since URLs are case sensitive!)
MMS Proxy and MMS Port: Not Set
MCC: 310 (Should already be set)
MNC: 260 (Should already be set)
APN Type: mms
APN Protocol: IPv6
APN Roaming Protocol: IPv4
Bearer: Unspecified
MVNO Type: None
MVNO Value: Not Set
Tap on the 3 dot menu and select "Save."
Reboot your phone for good measure (may not be necessary) and open Android Messages.
Send a MMS or group MMS on and off the Wi-Fi network you are having issues on to see if it sends. If you have several queued up messages that haven't sent, you may need to tap to resend them and they may become out of order on the recipient's end.
If you ever wanted to undo these changes, you can either reset the APN settings or remove the fast.t-mobile.com one.
Conclusions
The main thing to note about this is that it is the same as the other T-Mobile MMS APNs, but has TMUS replaced with fast.t-mobile.com. If you look at the actual default fast.t-mobile.com APN, you'll notice that "mms" isn't listed among the others in APN Type. I feel, if I could edit that default fast.t-mobile.com APN, the problem would be fixed by adding ",mms" at the end. I assume one could duplicate everything in the default one and add it that way, but I wanted to provide the simplest, non-invasive fix possible that would not result in any future or unforeseen problems. When the phone/Google Messages/text message app consults the APNs while on an enterprise Wi-Fi connection, I assume it goes through each one to attempt to find one with MMS in the APN type and then attempts to contact the APN via its domain name, but fails since TMUS is not valid. I am not sure why it doesn't go ahead, verifies a working data connection, and then sends the MMS using http://mms.msg.eng.t-mobile.com/mms/wapenc as it seems to do fine on other Wi-Fi networks. The phones are like, "Whelp, I'm on an enterprise Wi-Fi connection and I need me an MMS APN with a FQDN or I aint workin'!" I do not know what makes my company's Wi-Fi so different from my home Wi-Fi aside from it using EAP authentication. This wasn't a problem on my wife's previous phone (T-Mo Galaxy S7). I had the 2016 Pixel for a while, but I use Google Voice and would not normally notice the MMS issues.
If anyone has a good theory as to wth is going on, please contribute! I think its some sort of wonky Oreo issue. I hope this helps anyone who was as frustrated as I was!
Every family group text used to be a nightmare. This solved all my MMS maladies. Thank you for the nice writeup!

SM-N9860 apn issues

So I made the mistake of buying the N9860 (wanted dual sim) and now I can't seem to make the apn settings work. On Verizon. It automatically fills in the apn setting. Everything works but for some reason all the mms I receive are downgraded to like 30kb and are pretty much unviewable if there's any text in the image. When I try to add an APN it just doesn't show up in the list. The APN that shows up automatically is wrong... MMSC and mms port are not filled out but it will let me add them. If I change the MCC or MNC setting to 310 and 012 or remove the MVNO setting that's filled in when it isn't supposed to be there the apn no longer shows up in the list until I use "reset to default." Is there no way of disabling the setting that makes it fill in the apn info by itself? I've tried to disable "Select automatically" under network operators but it won't let me do that either.
