[Q] JB Global Mode and Data connectioin

I was all excited to get the Verizon JB update because of the rumoured "Global Mode", thinking I'd be able to pop in a SIM card from a different provider when travelling overseas.
However, gauging from comments on other forums, it seems that Verizon still keeps the phone locked, and allows only voice connection when the user goes on a different network when travelling outside of the US... Obviously, it won't work with competitors' network such as AT&T or T-Mobile...
The general consensus ( I won't be travelling for 5 weeks so I can't confirm this ) is that there isn't a way to enter the APN when a new SIM card is inserted and the users are only able to make phone calls with the new cell provider, but no data connections are feasible.
Can someone please chime it? Have you been successful in using data connection on your Verizon SG3 when travelling overseas? If so, how did you manage to enter the APN setting?
any input is greatly appreciated...
cheers,
James.

Download APN Global from the play store, once the international SIM is inserted, run the program and it should pull in the needed APN info....I've not tried it, only read about it on other forums.....so good luck

Follow the instructions here and you'll be good to go

[Q] S3 HELP!!!

Ok all I'm a newbie here so don't hate on me please.
My problem is that I cannot receive MMS and have no data other than WIFI??
I just rooted a Galaxy S3 (Verizon) SCH-I535, 4.1.2, Build#JZ054K.I535VRBMA2.
I set up the phone GSM/UMTS and am using an AT&T sim card from my old phone (HTC Inspire), the sim card that was in my inspire was on of the large kind that did not fit the Galaxy so the guy at Best Buy had a little stapler looking thing that actually cut it to the right size?? I don't know if that has anything to do with my problem or not? I don't think so since I CAN use the phone for calls and text messages, but you guys are the pro's. UPDATE: I did go to AT&T and get the proper sim card.
I used ODIN 307 and a file named-root66_VZW_I535VRBMA2_nowipe.tar.md5, to root the phone. I installed APN Manager Pro and Titanium Backup, both paid apps. I made APN Manager a system app in Titanium Backup just like I have read in other forums.
I have tried to use my old HTC settings for the APN and various others I have found online, including NET10 but nothing seems to work! I still can't receive MMS or network data??
If anyone can help me to figure this out I would greatly appreciate your help!
Thanks in advance!!

That's not gonna work...

You're attempting to use an AT&T sim card in a Verizon device. Setting the device to use GSM/UMTS instead of CDMA/LTE while using an AT&T sim card that has been modified to fit a Verizon slot still wont work... it's still a Verizon device. AT&T and Verizon may both use the same frequency bands of 850 MHz and 1900 MHz for 3G, and 700 MHz for LTE, but their commonality ends there. To my knowledge you can't get what you're trying to do here to work. Even if you could get it to work, it would likely not be an easy task.
If you want your Verizon SCH-I535 to work, you'll need to use a Verizon sim card with an active Verizon Wireless plan.
Sorry to be the bearer of bad news man... but its not gonna work.

Actually I did get it to work....somewhat. I downloaded the app HiAPN Global for the play store, made it a system app and viola! I now have data and MMS, HOWEVER it is not good by any means. All of my MMS come across as group messages and the data is EDGE at best.
I am wondering if I need to flash a new ROM and recovery....bootloader?? I'm kinda lost with all the information out there but cant seem to find my exact situation.

You will only get EDGE. i used to use at&t Sim in Verizon S3.
The way I got data to worm was flash CM10 stable FROM AT&T Version (i747) to the Verizon version (i535)
That doesn't mean ALL roms will work like that. You don't have to believe me that it worked as some people will say "You can't flash a att ROM on a Verizon phone".
Some Roms have MULTICARIER support. Try one of those. But again, you will not get any speeds faster than EDGE. Verizon has those bands locked for US carriers, but there unlocked for over seas. (Weird huh)
Edit: IM NOT TELLING YOU TO GO FLASH A AT&T SLECIFIC ROM. ALL IM SAYING IS I USED A AT&T VERSION OF CYANOGENMOD TO GET MY DATA WORKING.

VOLTE on AT&T

Though this phone is capable of VOLTE it has not, as of yet, functioned on my carrier AT&T. My line is supposedly provisioned properly in their system for VOLTE however the agent I spoke with informed me that an IMEI must be whitelisted on their servers before it will actually work. Basically this means that normally only the phones you buy from them are VOLTE capable because of their whitelisting system. Now this agent supposedly filed a case to get my IMEI added to this list which should supposedly allow for the VOLTE to then function on the AT&T network. And so if this actually ends up working I will report back so others can do the same if they wish to use VOLTE on AT&T.

Cool.... I tried the same but did not get offered to try and get my imei white listed.

This support doc from ATT mentions needing a specific SIM to be able to access voLTE. Did you make sure yours was indeed a UICC-G SIM card ?
https://www.att.com/esupport/article.jsp?sid=KB425890&cv=820

Yeah but that's not the problem this sim came right out of my att galaxy s6 which the VOLTE worked very well on. I'm gonna call back later today after work and see if my case went anywhere

I have a Pure on ATT, with a brand new NanoSIM card (picked it up from the AT&T store just after I picked up the phone); the 9th and 10th digits of the ICCID are '27', so it is a UICC-G SIM.. I was bummed to see that VoLTE wouldn't work on the device; all my investigation led me to the phone not being whitelisted in ATT's database. The 'Enhanced 4G LTE Mode' setting doesn't show up at all under Cellular Networks. I ran across a page that says to do the '*#*#4636#*#*' trick, go to 'Phone Info', and make sure that the toggle shows 'TURN OFF VOLTE PROVISIONED FLAG' (versus 'Turn On').. on my phone it showed it as provisioned to start with, but the option to enable Enhanced 4G LTE still is gone.
Apparently with Verizon customers, if the provisioned flag is on, but that menu option is missing, they need to log into their Verizon account and enable the 'HD Voice' flag on their account, at which point the option to enable it will show up. I'm guessing that basically whitelists their devices IMEI, which is the part we're apparently missing with ATT. :/

Hopefully it will, or else they will figure out that they need to let people who want this enable it and make it an account setting we can change! Verizon allows BYOD HD Voice, why can't ATT?!

I will follow up with ATT as well as they assure me that voLTE was available in my area..

Your APN also needs to point the the correct server.
APN: nxtgenphone
MMSC: http://mmsc.mobile.att.net
MMS Proxy: proxy.mobile.att.net
MMS Port: 80
APN Type: default,mms,supl,hipri,fota
My question is how to tell when you are on VOLTE?

If you can see the "Enhanced 4G LTE Mode" setting, and it's turned on, in theory it should work.
Then, when you place a call, your status bar's cell signal icon should still show 'LTE' instead of falling back to 'HSPA'.

I ordered this phone via Moto Maker and expect to have it in my hands next week. I currently have an older AT&T sim from my Samsung Galaxy S4, and imagine that I would need a new one to utilize VoLTE. Thanks to all of you trying to figure this out.

I found out from another at&t rep that the guy who told me about creating a case apparently did nothing but keep me on hold for a long time because she couldn't locate this apparent case anywhere. After asking her some hard questions I have gotten her to divulge that hdvoice and VOLTE are operating on lte band 2 or 1900 frequency. If I'm not mistaken this phone is already capable of that band right now even without marshmallow so there is almost certainly some sort of white list on at&ts part. Honestly I will probably write to the President about this because its not like its a security issue its just an absurdity

I asked a friend of mine that works as a manager at a corporate store here in town if he knew anything about it... He said it would be something to ask tech support, but he's not heard of a whitelist for VoLTE services. He did also say that most of what they do is just adding IMEI's to the system, and that they don't get BYOD cases very often...
I also work for AT&T, but not in the mobility side... Currently no contacts in the tech side of mobility either.

/scratches head
Am I the only one thinking that this really shouldn't be such a big mystery?
Especially for actual AT&T Wireless reps?

Here is a link to the ATT HD Voice info page... Turns out I have a goPhone plan and so HD is restricted.
http://www.att.com/esupport/article.html#!/wireless/KM1046250

It says in my online account that I am provisioned for VOLTE and from what I discovered from tech support the VOLTE operates on a frequency band that is fully supported by this phone. A whitelisting approach is then the only possible explanation at this point and I will be writing, the President to figure out why

It seems that VOLTE is not yet available on our phones. This is what I was told:
"Enrique: At the moment, VOLTE is only compatible with your Samsung S5 for the Moto X Pure, we are still waiting for a firmware update from Motroloa to have the feature enabled."
and then
"Enrique: Actually when the firmware is released, VOLTE will automatically be enabled on the Moto X, all you need to do is turn it on by heading over to Settings > More Networks > Mobile Networks > VoLTE"
So it seems we need a firmware update from Motorola. Maybe I missed something on this, though?

I called AT&T yesterday and they also confirmed that your account must be 'enabled' for VoLTE, but their "advanced' engineers (whatever this means) also need to provision your device on the back end. My ticket has an SLA of 12/22. I suspect it should be done much sooner than this and will also update everyone on my findings/results.

Just FYI, volte works perfectly on my MXPE on Verizon. I did have to call and have the feature added. Rebooted the phone, and it was enabled. The firmware DOES fully support it so the problem is likely on AT&T's end. Please keep us updated.

Update from ATT Advanced Tech Support.
"April: At this time we only support VOLTE for AT&T devices."
---------- Post added at 08:44 AM ---------- Previous post was at 08:24 AM ----------
So upon further discussion with ATT Advanced Tech Support, the MXPE is NOT on their list of approved VOLTE devices because it's not an ATT device.
That sucks.

Yep, AT&T is the worst carrier because they are one of the largest (just behind Verizon) and aren't bound to any regulation such as the C-block agreement that Verizon must adhere to. So, that means that AT&T services can be restricted to AT&T devices and only those devices. Verizon and T-Mobile have opened up VoLTE to unlocked phones, however Wifi calling seems to be another story. T-Mobile makes Wifi calling available to Nexus devices, and I'm not sure if agreements are needed between the carrier and phone manufacturer (or proxy for Nexuses - Google). Verizon will definitely limit Wifi calling to Verizon devices too, I'm sure of it, at least at the start. They'll make up some technical or security reason for disallowing unlocked phones.
I wouldn't worry about it too much though. VoLTE is more of a necessity for Verizon because they can't do simultaneous voice/data when on a CDMA call (2013 Moto X can). HSPA/HSPA+ supports voice and data. VoLTE often comes with other issues too, depending on network congestion. Unfortunately, carriers are struggling to keep up with demand for data, and VoLTE is no exception to that as calls are data packets.
VoLTE and VoWifi (Wifi calling) are part of the IMS services framework, and it is up to the carrier to allow access to that framework.

This isn't surprising. I recently had a HORRIBLE experience with AT&T U-Verse (yes I know, different department but same company). They sold me "fiber" Internet which turned out to be DSL and talked me into switching from 60MBPS Charter cable. Long story short, one of the many lies I was told is that I could cancel within the first month without paying any service or installation charges.
....so I cancelled in July only a couple weeks after starting service. I was told by a rep that I would receive a bill only because it's issued before the adjustments are issued and that the account will be zeroed out. The following month I called back when I got another bill. And I've called every month since (several times a month) and received the same story from every rep I've talked to. Each rep says they've zeroed the account but they can't e-mail or fax out any confirmation. I've even been told this by managers. Some of the reps are too lazy for this lie and they'll pretend I've called the wrong department and transfer me to a dead extension, which disconnects the call.
Yesterday I received a collection notice for this. That's going to ding my 809 credit score! AT&T is a shady company! As a long time Verizon Wireless customer I can say that I've never received this kind of service from any tier of their support. I'd highly recommend anyone having issues with AT&T to make the switch. What company can't send external communications? I've had Verizon reps send me e-mails, call me back, or even send official texts while on a call. AT&T is a garbage company and I pity any soul trying to get them to do anything other than bill you.

Need Ultra Mobile Working APN Settings

I thought to avoid unnecessary confusion I'd post in the General Questions as I'm unsure if it really fits in the others.
Anyway, I switched to Ultra Mobile recently, from Net10 Wireless. This involved activating an Ultra Mobile SIM, and swapping out my Net10 AT&T SIM. This unfortunately was the simplest part. Upon activation, I used the APN settings provided in the "activation" booklet that comes with the SIM. This resulted in a nice capital E lighting up my data icon.
As I am well within Ultra Mobile's LTE service area, with an LTE compatible device, I was quite frustrated. Changing the APN to ones suggested online to no avail, I called customer support. They were rather useless in solving my issue, the one I chatted with even suggesting I "wait for a whiel to see if connection improved" spelling and mechanics verbatim.
I am using a GSM unlocked VS985 (Verizon's LG G3).
Update: 4G connectivity works but not in my home area as I originally thought it would. Most likely the LTE bands on the G3 not supported by carrier in my area. Whatever the reason, works fine elsewhere.
Still need verified working APN to ensure MMS functionality.
Update 2. Talked with my friend who now works for AT&T, after working for Verizon for 2 years... Apparently, carrier signal coverage maps are to be taken with quote "several quite large grains of salt" and I'm probably just in a low signal area, contrary to the map's indication. Quite annoying but I suppose I can stop bothering technical support now.
Answers are no longer required but additional insight always appreciated.

Verizon S7 Edge (SM-G935V) on AT&T with LTE tip

Hi all, just giving a quick 2 cents after my recent experience attempting to activate a Verizon S7 Edge on AT&T.
*Following a data reset you will need wifi for initial setup if you are using an AT&T sim card.
After following the guide in AT&T's web site for APN settings I was not able to get any data or mms service (this is using the NXTGENPHONE APN), so I did some experimenting. The following APN settings worked for HSPA+ data and mms, but NO LTE and NO MMS if connected to WIFI:
Name: ATT
APN: phone
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://mmsc.mobile.att.net
Multimedia message proxy: proxy.mobile.att.net
Multimedia message port: 80
MCC: 310
MNC: 410
Authentication type: not set
APN type: default,mms,supl,hipri
APN Protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Bearer: unspecified
Mobile virtual network operator type: none
Mobile virtual network operator value: not set
So at this point I had NO LTE service and NO MMS IF connected to wifi. Utilizing the LTE Discovery app from the play store I could see that LTE was "not available" but on my wife's S7 she was getting LTE on Band 4. To make a long story short I got online to an AT&T chat rep who told me that HSPA+ and LTE are the exact same and they just show up different on different phones... THIS IS NOT CORRECT!
I educated the dumba$$ rep that HSPA+ and LTE are not the same, and asked to speak to a tech support SPECIALIST. After a short wait for transfer the final solution that worked was to have the specialist change the IMEI on file for my phone number to an AT&T branded Note 5 (I had an old one on the account and just used that). I then restarted the phone and had to wait about 10 minutes for the HSPA+ to change to 4GLTE signal. MMS now works when connected to wifi as well! Please note that this was achieved using the above mentioned APN settings- using AT&T's guide for NXTGENPHONE still results in NO data or MMS.
So the bottom line when transferring a Verizon S7 Edge to AT&T:
1. Use the above APN settings
2. Call AT&T and change your phone number's IMEI in their system to an LTE capable AT&T branded device (in my case note 5 worked)
3. Reboot and wait about 10 minutes for the signal to register
**DON'T let a representative tell you that HSPA+ and LTE are the same thing.. we're talking 8 Mbps vs 50+ Mbps download and 2 Mbps vs 20+ Mbps upload!
Cheers

Did you by chance even try the U firmware? It should work on any US carrier since its the firmware on the US Unlocked S7E and should have necessary files

you just flash the odin tar then root as usual.. the U firmware is for the US unlcked

I flashed first the 935U firmware and then activated the phone with AT&T, once you insert the sim the phone reboots, changes the APN while it reboots and once it finished all data/talk/text services with AT&T are fully functional. I am guessing Verizon lokcs down the APN features of the 935V firmware so that we stay with verizon.

I'm planning on flashing that rom tomorrow. The issue I have is modifying it for unlimited tethering as I use MetroPCS and pay for unlimited Internet. Fox fi does work but counts against my hotspot data. I tried it with a vpn but I use my hotspot for Netflix and I get an error saying to disable the proxy service or vpn. Wifi tether router connects but I get no Internet. I guess the main issue for me is getting the damn netflix to stream off my hotspot via chrome cast. I'm all ears, open to suggestions and help. Ps. I am currently rooted on Verizon rom. All apps are also paid apps not trying to free load here as I believe hard work should be compensated for. I also would love to have the video calling and wifi calling that I pay for.

My brother actually tried this. I sent him my 935V after I flashed it to the 935U firmware. He had the same problems the OP had where MMS and data won't work unless it's on the HSPA+ APN settings. He's coming to visit soon so I will try going to a store and seeing if they can set it up with a new sim. Or should I just call them and have them switch the imei?
Not sure which route is better here.

I actually just flashed the U firmware and now am right back where I started. Could be that for my region att has a hard time registering it. I'll be calling att this week and will post back my findings. I do like the U firmware better though. Seems cleaner and faster.

I think AT&T just block LTE access for non branded devices. Since you mentioned that it works after you register the sim with your AT&T note 5.

I just did a massive conversion of our squad car laptops for law enforcement at work from VZW to AT&T. The way they provision LTE access is trying the ICCID (SIM Card #) to the IMEID of the devices GOBI modem. All of my rigs came up on HSPA+ and not LTE. Once I sent the ICCID and IMEI of the particular unit to our government rep the mobile came up on LTE. I'd try calling them and saying you need LTE provisioned on your SIM. Provide the ICCID of your SIM, the IMEI of your device and your mobile phone #. Hope this helps.

I tried this with my brother's phone and they said that because it's a non at&t branded device there were limitations on what may or may not work when it comes to data or messaging because they don't guarantee anything as it's not theirs. So he had HSPA+ speeds for a few days until i saw this thread and called again. I gave them the IMEI from a display phone and it worked fine after that.

I tried this with my brother's phone and they said that because it's a non at&t branded device there were limitations on what may or may not work when it comes to data or messaging because they don't guarantee anything as it's not theirs.

Thanks, he didn't really care as he's just happy with the phone but I'm glad I got it working as it was intended. By any means necessary.

After flashing the u firmware I called att and was able to get it activated again. Just takes persistence and patience lol.

Glad to hear it worked. I remember when I had a Nexus on AT&T, and I had to call them to have LTE work using a different phones info lol.

Does anyone have any experience with Cricket? I'm thinking about using my S7 Edge on the U firmware with Cricket, but I know they don't have the same level or type of customer service as AT&T. I'm hoping it will "just work", but it sounds like it might not.

I flashed first the 935U firmware and then activated the phone with AT&T, once you insert the sim the phone reboots, changes the APN while it reboots and once it finished all data/talk/text services with AT&T are fully functional. I am guessing Verizon lokcs down the APN features of the 935V firmware so that we stay with verizon.

Hi Geoff,
Don't know if you're still considering using a Verizon S7 edge on Cricket. I currently have one and it works fine with the network. And I have no issues with calls or MMS via LTE. You only lose connection go Band 17.
