After several long calls with Verizon and help from Motorola insiders, I have been given to understand that:
1. Droid Maxx if not activated on Verizon, before leaving US, cannot be used on other carriers (say in Europe or Asia).
The reason is the SIM unlock cannot be done by the customer support since they won't see the device in their network if it is not activated first.
2. The activation cannot happen outside US, since Verizon does not have a network.
So bottom line is get the device activated before you import it from US.
Now, my Droid Maxx is locked to Verizon. I know the boot loader can be unlocked. Will this help me in flashing something that can get rid of the SIM lock that Verizon has in place.
My device is an employee edition so perhaps there was some extra protection added there by Verizon.
Please help.
I do not have a Maxx, but I'm replying because you PM'd me asking to take a look at this thread..
It has been my experience that Verizon's 4GLte phones are sim unlocked (on the GSM side) out of the box. I thought that was a condition of VZW's 700Mhz spectrum auction win? One potential issue is does the phone support the needed bands out of the box (think Bionic where a hack was needed to enable bands needed for T-mobile).
That being said, if your Maxx is truly SIM LOCKED, then unlocking the bootloader wont help you SIM unlock, nor will flashing a 3rd party Rom after unlocking the bootloader.
where are you located, and who is your carrier? Do they use CDMA for voice, or GSM? What happens when you put a non-VZW sim in the phone?

Thanks Mark.
The phone Droid Maxx does support these bands since there are others who are using the same phone on GSM networks in the country.
The networks in India are:
2G capabilities GSM 900, GSM 1800
3G capabilities UMTS 2100
4G capabilities LTE 2300 (this one won't work with the phone, plus my carrier does not have it either)
The CDMA is CDMA 2000 - but I have not been able to try with a CDMA SIM, but that one has a higher probability of working.
When I put a non-VZ SIM, and set to Global mode, it does not detect any signal and the search network does pretty much nothing. The automatic mode tries to connect but then throws an error saying "can't connect to this network at this time"
I am using a brand new nano SIM card (which now is back in my Moto Defy with an adapter.)
Earlier I had a normal SIM converted to a nano SIM and that one did not work, but after I put in APN manually, I was able to access data.
I tried another user's cut-nano SIM and that one worked for data out of the box (another GSM provider).
Ditto for me, but I am using DroidMini... I also have DroidMAXX which is working great (even unlocked its BL and rooted it)...
I am also from India... Using it in GSM networks... I may get one Nano CDMA SIM to test later and will report here for sure...
Thanks...

Well, we have interacted on Rimweb recently.
The radio on the Droid series is the same. The difference between the mini and the maxx in your case is that the mini has never been activated on VZ network and hence it is SIM locked. Whereas, the Maxx would have been purchased as a used item (perhaps just activated and then sold off?). So that takes care of the SIM unlock part.
Yesterday I spend around 60 minutes with global support, VZ.
I escalated the issue to the supervisor.
He checked and said that the IMEI is clean and not in any sort of negative list. So there is nothing else that they can do.
He also said, the phones are unlocked by default for global use.
Obviously they don't want to dig deeper into why three phones are not working on GSM in India.
I am now running out of avenues. Does anyone have some debugging tool which can log what is happening when the phone tries to log on to the network?

The current Droid Maxx that Verizon sells supports the following..
LTE Band 13/4 700/1700
EDGE/GSM: 850/900/1800/1900,
HSPA/UMTS: 850/900/1900/2100 (download speeds to 42.2 Mbps, upload speeds to 5.76 Mbps
From what you listed, the Maxx should get GSM/Edge/HSPA/UMTS coverage there. And of course, no LTE.
The CDMA side of the Verizon phones is still "locked" so I also would not expect CDMA to work. In other words, if your carrier NEEDS CDMA, stop trying.

I've been through this with some trying the Moto X in India, and I've been through it while trying my T-Mobile and ATT sim's in my Verizon Moto X.
From what you are describing, it sounds like your APN settings for your carrier on the phone are not set right.
Example... When I put my T-Mobile SIM into my Verizon Samsung Galaxy S4, I get "unknown sim" and bars, but no network connectivity. Nothing works. By going into the mobile network settings on the phone and adding an APN with the T-Mobile settings, features like calling, SMS, data, etc. start working. I have had occasions where I thought I had the APN right, as calls and data worked, but MMS only partially worked (would send but not receive). When I do have the settings right, everything works. Similar thing happens on my Moto X with T-Mobile SIM.

Unless you have an active account with Verizon, and are trying to use their service when traveling, Verizon wont help you. In other words, unless you are trying to get your Verizon phone, working on Verizon's Global Roaming service, on your currently active Verizon account, they wont help you.
Even if you are a Verizon customer who is just traveling and popped out your VZW SIM in favor of using a local prepay sim to save data/voice costs, once you pop that VZW SIM out, they wont assist.
But you have received confirmation of what I said.. the GSM side is unlocked.
The SIM you are trying to use is from a GSM India carrier? As long as they only use GSM (no CDMA required), your only hope will be working with them. Telling them your phone is SIM Unlocked and going from there. Or finding a local message board for the carrier, and hope people are discussing use of "3rd party" phones, and you might get some help there.
I really think it will come down to the APN settings for the GSM carrier not being correct on the Maxx.
I can't offer any more than that. Sorry.

I have now put in a CDMA SIM card, but run into another problem with that. I will activate that SIM on another phone and then pop it in the Maxx again and check. But CDMA should work fine as reported by other users.
But the problem is the GSM part, because that is what we need to get working.

That is bad on the part of Verizon. I have purchased a Verizon device off-contract and that device is a global one. So I am entitled to some support from them even if I am without a service plan.

Yes. Local carrier. And for now, there are three such XDA members who have been facing the same issue. In one case, a member was able to make calls and receive calls and also use data. Then after a few minutes, the SIM invalid message popped up.

APN settings are pretty easy. I did that with my earlier SIM and I got data working. There was no voice, so I gave that SIM back to the carrier and got a brand new nano SIM. Now, nothing works. The old and new SIM are for the same number and same service provider.

Right, you got just DATA working with the APN settings, but the correct APN settings are also needed for SMS, MMS, Phone calls, etc.
I've had an issue where I had voice but no data, and it was related to APN. I've had an issue where I had voice, SMS, data but no MMS, again, it was related to APN settings for the carrier you are using.
So good luck!
the problem we sorted out to get gsm working in india first the phone must be activated on usa to get it work on india so can anyone help us > @s_u_n
So, after using the phone for a week on GSM with all application updates installed, I can safely state that
1. Verizon activation is not needed for non-VZ networks to work (at least outside US).
2. A full FXZ was installed and it probably solved the modem configuration mess that the phone might have been. Perhaps it unlocked something?
3. Four corner activation bypass method was used (as described in earlier Motorola phones).
Either 2 or 3 solved the problem
There was nothing to do with APN. Data works even without any APN settings out here, just like on my Motorola Defy.
Starting to do my research on taking my Photon Q LTE from Sprint over to FreedomPop.
Has anyone done this yet?
How did you do it and what is your opinion of the entire experience?
Is it Officially Supported by Freedom pop? If not, when?
If not supported, how to get a Photon Q LTE on FreedomPop now?
If you have any experience with FreedomPop service, please give the geographic service area you've tried and your impression of the FreedomPop service.
Thank you.
No LTE for all "SIM-cards" except the buit-in one.
There is afaik no chance to get LTE working with another carrier than the original one (sprint).

But FreedomPop is a Sprint MVNO...
I'm not saying this will guarantee it'll work, but I'd say there's a much better chance it will.
I'm kind of curious, but not sure I'm ready to switch my phone to FreedomPop. Maybe I'll try it out on my roomie's phone first...
4g LTE works for the photonQ on Voyager Mobile and Ringplus, those are the best sprint mvno's imo...
Then it have to work without hardware modding, right?
If I'm wrong and it works with a hardwaremod, then other carrier with the same LTE frequency should also work.
I'm kind of confused, how LTE is working in our Q.

What we mean by Sprint MVNO is they basically resell Sprint service. So you aren't paying Sprint directly, but you are using their towers/network. The MVNO leases the network space from Sprint... Pretty much all the big providers lease space on their network to gain another revenue stream.
Yes, I know what a MVNO is.
But in my country you need for each MVNO an own SIM-card.
I assumed that something similiar is done in the US.
If you can change to another Sprint reseller without the need of change something in hardware, then it might work.
I'm probably unaware of the typical US mobiles and the carriers technology.

Typically MVNOs that operate on GSM networks have their own SIM cards, however CDMA carriers (such as those running on Sprint) identify the phone by its internal ESN. Since there is no SIM to swap, the ESN has to be reassigned from Sprint to their MVNO.
And FYI, the Q works beautifully on Ting as well, LTE and all.

Nice, thanks for the explanation.
Now, is Ting a GSM or CDMA carrier/MVNO?
I assume it's a CDMA MVNO, which works inside the sprint network and is (because of sprint) able to operate in the LTE network.
Freedom Pop is a rip off I set up a free data account and they tried to charge me. The only customer service is through there forums.
I use Ting they are great.
They resell Sprint.
Sent from my PHOTON Q using XDA Premium 4 mobile app
Recently revived my N5 that had been sitting around due to my N6P showing some water problems in case I needed to switch phones quickly.
Well, after resetting and installing AOSP Extended, I put my T-Mobile sim in, and gets no signal. It will recognize a sim is in, but I get no service at all. I figured something could be wrong with the simreader, so I tried some other sims. Sprint sim and a Freedompop(AT&T) sim both work. I know my T-Mobile sim works, as I'm currently using it in my 6p. Anyone have any solution?
freedompop uses at&t for GSM devices and sprint for CMDA devices. it sounds like your phone is the CMDA version, and your using the sprint network with freedompop. T-mobile is a GSM network and will not work with CMDA phones.
Specific to dual sim with Tmobile and Verizon - Unlocked version 7 pro:
When Tmobile SIM is data sim, both lines show VoLTE in status bar, and 4G under each sim. When Verizon is the data sim, only Verizon sim shows VoLTE, and Tmo is UMTS. Could this be a provisioning thing on tmo side? They see my phone registered as 7 Pro, but Tmo billing site shows unknown device.
Or does TMO require data for VoLTE and Verizon is looser allowing VoLTE when not on data because they have no 3G to fall back on?
Just wonder why Tmo falls back to 3G and doesn't use VoLTE when it is not the data sim? This implies there is something better about falling back to 3G when possible - maybe battery life or coverage?
I'd also like to know this if anyone can explain
Acknowledging that this post is rather old but I am facing the same issue. I have the issue with my 2 T-Mobile lines that I'm using in an unlocked OP7Pro. No chance to get VoLTE or VoWiFi going for a line unless it is the active data line. Given that T-Mobile wants to go LTE (and 5G) only early 2021 they should get this sorted out...
@FSOP @chromedome have you found out anything more on this topic?

I think it has to do with Verizon only has LTE on this device, so no matter what the Verizon connection is LTE.
Will an unlocked TMobile version of this phone work on an existing Verizon line without having to ask verizon to white list the imei or add cdma less etc?

I have Unlocked T-mobile A71 5G, It works on Verizon network like 4G LTE (just swap the SIM card even I have 5G Sim card from Verizon) but NO 5G because they are using different 5G Band.
I have the same question, but on cricket wireless, I can't get the phone to login to their network
It works just fine on any GSM/LTE network. I have not checked this personally for this device, but depending on the variant you have, you may be missing some LTE or 5G bands specific Verizon. You may not get full performance. That must be verified though.
