[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
Glad I was able to help!

Since "S" comes before "V" alphabetically, that's why your default APN was "Straight Talk". It's been discussed in depth over in the Resurrection Remix thread, and some Verizon users were just incredulous they would even have to choose an APN or why Verizon would not be the automatic default choice.

However, even now, there's something you should check about the MMS settings on that APN. See the settings screenshot at the bottom of this post? On some custom ROMs, the VZWINTERNET APN (while the correct APN for Verizon users) had messed up MMS settings. Just double check?

Yeah, for some reason Verizon users don't think too much about APNs. I'm not bashing, I'm just pointing out what I've noticed since the Droid Turbo XT1254 got bootloader unlocked in late 2015. Probably a combination of factors?

* Before LTE, Verizon didn't have APNs.

Yes, it's been just over 6 years ago (very late 2010) when Verizon LTE was launched, but not everyone upgraded to LTE phones immediately. Some people only got LTE phones 2 or 3 years later. There's still a lot of long-time Verizon users who think in terms of PRL (CDMA), not APN (which was previously just for GSM networks). My first Android was on a regional CDMA network, so I'm aware of PRL. Even when I got an LTE Android on that regional network, the only custom ROM available for that phone was stock-based which didn't need a different APN.

* Verizon users don't have as much experience with non-stock based custom ROMs. ROMs like CM/LOS, AOKP, AOSP, etc. Verizon locks down their bootloaders, so across their inventory their Android phones don't get as much development. (Of all the Motorola Quarks, only the Verizon model has a carrier-mandated locked down bootloader. Even the U.S. Moto XT1250, which is the identical clone to the XT1254 has an easily unlocked bootloader upon request to the manufacturer. )

With bootloader locked down and on stock firmware, when you stick a Verizon SIM card into a Verizon phone you don't have to choose an APN. Even with CF's "stock-based" debloated, tweaked Verizon Marshmallow ROM, it's built for Verizon users, so I believe no APN choice is necessary. Verizon APN is just there already.

* Coupled with all that, historically Verizon has not had as many MNVOs as AT&T and T-mobile -- a plethora of MVNOs whose APNs are now included in custom ROMs.

Yes, Straight Talk has been around and been a Verizon MVNO for a long time (they also are MVNO to AT&T, T-mobile, and Sprint) -- but for a few years Verizon would not let MVNOs have access to LTE. Even if you had a Verizon LTE phone, on an MVNO you were limited to CDMA voice and data.

August 2014

It was actually

October 2014 before any Verizon MVNOs got LTE data.

About 4 years into the less-than-7 years Verizon has had LTE. Whereas AT&T and T-mobile MVNOs had LTE access well before then, and thus Android users on those carriers (or affiliated MVNOs) with custom ROMs knew to check APNs to either choose or avoid those APNs. ;)

But Verizon users didn't have to contend with that. Custom ROMs for them did not have MNVOs listed because Verizon MVNOs didn't have access to LTE.

All this is why some Verizon users are a little behind the learning curve on APNs. But now you know.

"VZWINTERNET" APN

Look at the MMS settings at the bottom of this post. This part below is a re-post of mine from another thread. You've already now chosen the correct APN, so ignore that part -- just look at the MMS settings.

Check your APN. A LOT of people for some reason are on Straight Talk APN -- which has messaging issues, when they are Verizon customers and should be on Verizon APN.

In CM/LOS based custom ROMs about a dozen APNs are listed for various Verizon MNVOs. Since "S" comes before "V" the default APN ends up being the WRONG one. You should DELETE all the APNs you do not need, except for the one you will be using. This has been discussed many times in various custom ROM threads...

The correct one for Verizon customers is "VZWINTERNET". Delete ALL others, unless you are a Straight Talk customer -- in which case I feel very sorry for you. But for the CM/LOS APN you will need to edit the MMS settings.

These are the MMS settings you should have in that APN, courtesy [MENTION=2640499]koftheworld[/MENTION], from one of those previous ROM thread discussions:

More about Straight Talk...

Straight Talk (Verizon version) does use the Verizon network but they have the lowest priority -- as they are an MVNO using Verizon's excess capacity. Straight Talk uses proxy data servers (at least on AT&T version), so you will get slower data speeds and more lag (if the Verizon experience is similar to the AT&T version of Straight Talk), and any MVNO customers will be kicked off for "real" Verizon customers if there's any congestion. Also one of Straight Talk's practices was to batch-send messages, sometimes hours later.

If you are an actual Verizon customer paying Verizon for your account, you should not be using an MVNO's APN. At best you are being served hamburger at steak prices. At worst, you won't be served at all.
