Looking closely .. only thing I'm seeing is that you're on TMO with 4G and 4G/LTE .. is that what you're trying to point out ?

I read that you can unlock frequencies on factory unlocked phones? It seems to be okay but I would like to double check

Yeah it took a week and they had to call me back, but finally got it

I might be in a re-farmed area, but so far I'm getting 4g, and LTE exactly the same as my tmobile iphone 5. Maybe it's already AWS unlocked? How do I tell?

I do want to confirm that I am getting AWS on my factory unlocked S4 Active with no mods. e, 3g, 4g, and LTE. I know this because on my hacked note 2 without the AWS mod i couldn't get all that.

Is that a slothtronaut? Cosmosloth? I didn't know NASA sent those things up.

I am only getting 3G on T-Mobile and I'm in a TMO 4G area that has not been re-farmed. I wonder how you are getting 4G??
Edit: I am not able to use the AT&T S4 guide to unlock frequencies as my device reboots when trying to enter the setup menu provided in the instructions.

Yes, I got the unlock code from them yesterday and the first thing I did was to pop my TMO sim in. Only 3G for me. So then I check my apn settings and configure it for fast.tmo but that doesn't even connect up, had to us EPC.tmo for the 3g to connect.
Did you have to mess with your APN settings?

It took about 3 minutes after putting the SIM in for it to auto configure. Then rebooted and data came online all bands. APN is epc.
Maybe you need a different SIM?

I'd have to second the notion that you might need a new SIM.

I've been taking screen shots. I've had every data possible. e, 3g, h+, 4g, and LTE. The ATT unlock code definately unlocks the AWS flag in the NVRAM.

When I got the code from AT&T it took less than 10mins and I don't even have AT&T. But now they got a new rule about giving unlock codes I had to call twice because the first person wouldn't give me the code but the second did.

[Q] Has anyone manage to connect to metro pcs gsm?

I figured I would try asking. I get edge data and calls are working. No 4G though and I havent tried MMS yet. I called metro's tech support for their apn settings and they don't seem to work.
If you have your ATT Note 3 working on Metro's gsm service, please share your settings/experience here. Any ideas on how to get this working would also be great. Thanks in advance! :good:

I bought two Note 3s and gave one to my friend who's on metro. Everything works perfect for him, 4g, MMS and everything else.
He Input his APN settings so I'm not sure if he did anything else. When I get off work in the morning I'll ask him if he did anything specific besides the APN settings and let you know.

This may be a dumb question but did you switch your network mode to LTE/WCDMA/GSM option?

I have a question for you, did you buy the phone and stick your sim card in, or did you actually go to the Metro store and have them program the sim for the phone? Metro's sim cards work different than most gsm carrier sim cards =/

I went to an actual metro pcs store and bought the sim. The employee scanned the bar code on the back of my phone, so I'm guessing they programmed it specifically for my phone.

Ok so called my friend today. He told me that he didn't input the APN settings, they loaded automatically. It did make an APN profile for him. He sent me the following screenshots.

I also noticed that too! Yes he does normally have 4g/lte. His home is one of the ones where you take one step to the left and you have edge. Happens to me too and I'm on At&t lol. Let me know if you have any luck with it.

How are you suppose to know what the password is and the server as they are just **** in the screen shot?
Sent from my SM-N900T using xda app-developers app

No go on the apn settings. I am planning on driving out to LA sometime later this week and will check out whether this lack of LTE is only in my area. Sucks coming from metro's great cdma service.
Also quickvic has a good point about the password, although I'm thinking tyiphius friend's apn settings were installed automatically

Anyone know where I can buy a N900A note 3 that will work on Metro LTE?

[Video] Verizon On my nexus 5

Took the sim out of my Verizon s4 and was determined to get this N5 up and running on big red.
I have full lte after a lot of tweaks that I probably shouldn't post right now do to what it could possibly do to a phone.
If you are a Dev and think you can do more with this let me know and I'll get you to where I'm at. I'm just a themer with basic dev knowledge. As you can see there is no signal to text or call. I've had bars a few times but that's it. As you see I'm on L. I had to crop one screen on phone because of upload size restrictions.

Looks interesting so far. I can't recall whether this device supports VZW's frequencies. If not, calls may never work.
I'll assume you modified the APN for VZW. Did you try modifying the radio?
If you post what you did to get data working, other members may have some additional suggestions to get you moving again.

its been gotten to, the lte connecting. but it's the calling ability that cant be done. i dont remember what all really came about, but i do remember thst the calling ability is the real issue. the nexus 5 doesnt have the ability to make phonecalls via lte. if you search the forums here, maybe you can find the thread.

Calls won't work for two reasons 1) I don't think Verizon uses VoLTE yet, and 2) calls still use 1x, just like Sprint, and you have to have the MEID (IMEI minus last digit I believe) in Verizon's database. Technically it should work on Page Plus and I think I saw a thread here on how to flash it for PP. I'm kind of surprised Verizon LTE works as most of the bands for Verizon's LTE don't coincide with the N5 IIRC. I could be wrong about that though. Also it's probably like any other GSM carrier, once you activate the SIM card in a carrier based phone, you can stick it in another phone and it should just activate. The only reason you have to change IMEIs is for the EVDO/1x backwards compatibility.

i may return to big red, im currently testing out net 10

Posted a video of me getting data after a fresh wipe and install of L.

http://www.droid-life.com/2014/08/26/verizon-volte-hd-voice-launch/

I really need to remember to watch OP's video when I get home. This is very exciting. So to get data, you had to activate a Verizon device and swap SIMs, right? After that, the only thing not working is the CDMA voice? So in theory, if the above poser's link is correct (Verizon rolling out VoLTE soon) I could actually switch to them?
It's Verizon so I probably wouldn't do it permanently, but it would be cool to try for a month, if for nothing more than a proof of concept or neat trick. Hope Verizon does that soon.

This just won't work bro, not on CDMA.
I worked for Sprint and their system is the same.
The SIM card is strictly for LTE, everything else goes over the CDMA network, which requires server authentication.
Even when VoLTE will roll out, that authentication will remain in place.

People have got data in the past. Its voice that's the issue.
Sent from my Nexus 5 using Tapatalk

he can get voice & sms on it, though not via the sim card number;
I replied to the video with -
"..though it won't be your Verizon mobile number;
you could try using ring.to / grooveIP for voice / sms via the lte connection..
I use that as a back up number on sprint, mostly for lte , wifi , evdo routed calls,
even gsm / hspa+ & wifi when sim swapped out of the country on my nexus 5.
after editing the echo settings, it should work wonders thru that Verizon lte connection.."

just thought of something, real simple..
the cdma radio authentication is what's stopping the nexus 5 from being on Verizon,
but... **does the lte band need the same authentication**?
let's just say, on my nexus 5, with the new google voice hangouts / sprint number integration,
i go through the dialer into settings to toggle **lte only** which disables the cdma radio,
pop in a Verizon unlimited data sim, in an area with verizon's band 4..
over the top, voip service on lte..?

If you refer to my post, my point was only that there's a little app that shows the Android service menu. The band is indicated (mine says HSPA - my contract doesn't allow LTE, so I can't say anything about that).

that app your referring to is the same menu as going into *#*#4636#*#*
also, HSPA, LTE, GSM, etc is not the band type, its a network type.. by Band type I mean LTE: Bands: 1/3/4/7/17/38/40, which is also another way to describe radio frequency
as you can see in the first pic of my first post, in the Samsung device, it shows Band 4
but my question was for mindblizzard,

I don't think the phone can show that information

That's all fine and dandy, but it's not like your carrier is operating multiple frequencies that you're likely to see ever. Maybe if you live in an incredibly dense population center, but even then... Perhaps I'm missing something.

Fair enough, if you have LTE already, and they are simply deploying a new frequency, you likely won't notice any change, to any of the service. Speeds don't increase between bands, the only reason a carrier deploys a new band, is to fight radio interference from other carriers. Given the cost of a single radio, carriers generally only deploy these new radios in VERY congested areas. Meaning, that in a city that has, say 15 towers, 2-3 of them would actually get the upgrade, in the area that suffers from the most interference. (You have to bear in mind, that a full tower build, requires 6 radios, each radio costing about $18,000 for the radio, another $1000 for the antenna, another $500-1500 for the power supply and cabling. They don't just "upgrade" an entire area, it takes too long to recoup costs)

Ah my mistake, i had in my head he meant to check for bands in the area which he can use with the 'unlocked' frequency mod..for some reason. My total mistake!
However what i meant with what i said when i get my 4g is that i can confirm that the unlock mod will enable band 20 since our OPO is restricted/doesnt support it by default. The band app would be good though!

thanks for the link; i figured out the codes shortly after posting my message.

Rather than turning off band that provider might actually use in some situations, try turning off band that you possibly won't use, like band 39, or whatever.
See if that fixes preference to band 4, while still maintaining band 12 for odd situation.
I'm only saying this, because in Canada for provider freedom, band 66 is the fastest, and international phones actually prefer to connect to band 4 which is the slowest for this particular provider. Since we don't have access to modem settings since oreo, I found that disabling any of the unused bands (30,46,39 whatever), brings back proper behaviour like Canadian model counterparts, choosing band 66 majority of times, while still maintaining band 4 for building penetration.
Just try, give a few minutes, check on *#0011#, see if you're still defaulting to 12, or something else with more throughput, might work, might not.
