[Q] ATT Note on Tmobile network

Hi
I have a ATT Note 2 with a t-mobile sim in it with ATT rom/modem/etc. The HSPA worked for like 2 minutes and never worked again. 2g works fine.
Has anyone gotten 3g/3g+ working one ATT note 2 on the tmobile network?
I know note works but couldnt find an answer for Note 2.
Please advice!
Thanks

^^^^^^ 2nd this.
ready to acquire GN2 ATT from local CL. but since i use t-mo cheap 5gb data plan, i am not sure how to benefit the plan. just a thought, you said HSPA worked for 2 mins (or so..) ? did you do any browsing/data usage and get result ? or just monitor the signal bar switching from H+ to E ?

I did a speed test and got 5mbps download. I also have the 5gb plan. There must be a way to get it to work!

Check and make sure your apns are correct.

Has anyone tried flashing a t-mobile modem?
Sent from my SAMSUNG-SGH-I317 using xda premium

I did - it gave me no service

Did you tried flashing a T-Mobile ROM??

yes didnt work either..

@ vish :
another shoot in the dark, do you think it has a relation with the phone being unable to toggle to 3G / UMTS mode ? will you please flash the t-mo radio back and tried :
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.

so with jedi ROM x 6.1.2, 4g signal stays intact ? can you please do speedtest & post it here ?
btw : this 4g signal, supposed to be H+ in t-mobile ? or is it just UI issue ?

Sorry for the late reply - i tried flashing tmobile model and I got either bootloop or no service. Even with the sim card out.
Any other ideas?

Are you sure you are in a refarmed area? Cause if not you will ONLY get EDGE

^^^ what he said. T-Mobile is refarming their network to be compatible with AT&T's 3G frequencies but only in certain cities right now. Check their website, it tells what cities. They may be testing in your area. Otherwise you'll only get edge because the note 2 can't do what the note 1 did. It's an exynos thing.

Has anyone tried this SIM card release thing to force 3G on t-mobile network on a AT&T Note 2 phone? did it work? or did I misunderstand this post to be a solution to getting 3G/4G on tmobile network?

Only edge will work. Get a t mobile device or switch to att.

SIM Unlock LG G Pad 8.3 VK810 Verizon to AT&T

I have been searching and cant seem to find anything... :/
I am trying to SIM Unlock my LG G Pad 8.3 Model VK810 that is Verizon and should come factory unlock I believe. I need this to be used on AT&T LTE which I have a sim card for and a tablet plan on the shared data plan.
It is on 4.2.2 baseband is m9615a-cefwtazm
I tried adding some ATT APN settings I found, but that did not help me. I think I need to Change it to GSM From CDMA somehow? I am not really sure. I can update and root if needed or whatever I need to do. I also have a samsung z3x box, but dont think it will work on the LG.
Any help would really help me out! Thank you in advance.

As it seems you are comfortable messing with your APN settings that should be all you will need to do. The device is locked to specific wireless frequencies but luckily for you at &t uses the same LTE frequencies. You will need to have root access in order to write your APN settings though, check the forums for information on that. Finally make sure that the sim you have is compatible with your tablet data plan, and your APN settings should be as follows for mobile data only.
APN: BROADBAND
MCC: 310
MNC: 410

I do not, I am sure you will find something if you look around. The V500 and V510 methods are not compatible. There is a method for yours though along with a custom recovery in the works. You may even have a custom rom in the near future.
P.S. this topic belongs in Q/A and not development.

So, I should Root this and then change the APN settings to what you told me and my ATT SIM would work?

I haven't read much about i0root but it looks like it will work. Now the next part is not certain weather or not it will work, but I have seen tablets able to run on other networks that are unlocked. As long as Verizon did not implement any extra protection you should be able to use an at&t sim that is enabled for tablet data.
Once you are rooted go pick up es file explorer and navigate to /system/etc/apns-conf.xml . Make sure that before you change anything that you make a copy and name it something else so you can find it again if you have to go back. Open the file using the text editor. You can get rid of the other apns and just put your new one in there and give it a reboot. It should kick right on after you reboot. Good luck!

Any ideas on how to get these drivers installed to try the next step? I tried to go ahead and run the iroot program but it can not find the device.

I have installed a T-Mobile SIM card in my LG GPad 8.3 LTE so I could get the free gig of data they offer existing customers. It worked without rooting. All I did was add a new APN with the proper T-Mobile settings and I was able to surf. Did it right there at the T-Mobile store with the rep to verify it would work before I added the data line to my account.

Thx for the tip. The tablet is set to LTE mode and since T-Mobile LTE has the same band with Verizon LTE. It definitely works on T-Mobile.
For AT&T, no luck even if rooted. I used Radio Switcher app to go to the Tablet Info in Testing Mode. But it displays error message "This application does not work on this device".

Easy...
Vk810 supports lte bands 4(aws) and 13 (700mhz block c), bands that Verizon uses
T-Mobile uses band 4 for lte mainly, will use band 2 (1900) and 12 (700 MHz block a) in the future as well. Vk810 will work on T-Mobile wherever tmobile has LTE right now (with band 4)
Att uses band 4, 2 (1900), 17(700mhz block b) and 30(2300mhz). Vk810 will only work on att if at uses band 4. If att only used band 2 in your area, your att phone (which supports band 2) will show LTE, but vk810 won't work
I don't know if there is a map showing which bands att uses in your area. There is a spectrum map showing who owns which band in which region, but no guarantee that att has active cell sites

How were you able to set up up the G Pad with the tmobile sim ? I went to the tmobile store and they were not able to get service running. What settings did you use ? Any help would be appreciated.

you need to insert sim, reboot device (it'll prompt you to)
then you need to add the t-mobile APNs to the device

I see people here say this tablet is unlocked. I rooted & inserted an at&t sim, but not working. It shows a greyed out singnal bar and a circle next to it. Then I edited build.prop ro.build.target_operator=VZN to OPEN. Now the circle is gone leaving a greyed out signal bar with small red x above it. I'm on 4.2.2. Can someone elaborate?

this device is unlocked... it accepts any SIMs, and works w/ any band 4/13 network
AT&T's network accept any device that's approved for GSM/LTE spec, and compatible with their band 2/4/17/30 network.
AT&T doesn't have band 4 everywhere.. for example, no band 4 in nyc region.... this device won't work on at&t in nyc

no LTE on at&t - unlocked m919

I've seen several discussions about this but didn't seem to find a working solution. I'm currently using GNF1 V3 NB4, I tried using the apn settings for at&t and also called them to make sure they have the correct imei number. Also, for some reason under the "Network mode" I don't have an LTE option, I only have WCDMA/GSM, GSM ONLY AND WCDMA ONLY. I am able to get 4G but no LTE. Is there any solution or any other way to solve this problem?

will it also change the speed or just add an "LTE" symbol?

ok, i have the LTE option in "network modes" now, however the speed is more or less the same and I don't have LTE bar, not sure whether it's because of my current location or what.. is there anything else I could edit to try to make it work?

If I change the ro.product.model , name and device to at&t values would I get the LTE speeds just like an at&t s4?

When I bought this phone from T-Mobile I was still on an AT&T plan. Before I jumped ship over to Net10 Wireless I used AT&T's LTE all over Pensacola. That was on a sim-unlocked, unrooted, otherwise 100% stock M919. Did you double-check your APN's? Perhaps you're just not in an area where you can pick up LTE?

Yes I use the correct apns the ones that at&t gave me, but im gonna try to go back to stock then change the apns to at&t and maybe that will work.. but even if it will, I don't know if I could keep using GNF1 or would I have to use a different rom, anybody else have or had issues with getting LTE on at&t while using custom roms and knows roms that work? (Preferably tw)

See your network type in settings > about phone > status. Try to get LTE with your AT&T SIM on another phone then install it back to your M919.

Maybe with hidden menu access via dialer,you can permanently enabled it...I don't know the actual code that might work for your device..but you can find it through here..In general threads maybe

I had to set the proper APNs on my H815, additionally I had to tell it to use GSM/WCDMA/LTE Auto under Network Mode in the Mobile Networks settings.

Thank you @Daptonic . I was attempting to use the "ATT nxtgenphone" APN because it works better on ATT devices but I guess the ATT Phone APN is needed for non ATT devices. Rebooted phone and it went straight to 4g. Thanks for responding.
Edit: dammit, it went back to hspa again......

Explain my 4g LTE woes, Verizon on T-Mobile

I may be trading my Verizon G4 for a T-Mobile H811 but before I go through the trouble I'd like to see if my problem can be fixed.
My network options are:
Global no sub-network menu
LTE/CDMA also no sub menu
LTE/GSM/UMTS with sub menu options LTE/Legacy 3GPP multi, GSM/GPRS/EDGE only, and UMTS/HSPA/HSPA+ only and the option to choose network operators.
When I choose LTE/CDMA I get 4g LTE all the time, great speeds, but am unable to send texts, not sure about calls(don't use the phone much for calls)
If I choose Global I get intermittent LTE but mostly HSPA or HSPA+. Again texts only work when it switches to H.
If I choose LTE/GSM/UMTS I mostly get HSPA but occasionally it will switch to LTE.
I'm not used to having all these network options to choose from. I've tried a few different APN settings and all give the same results. I'm in a very good LTE coverage area and my G2 always ran on Band 4 LTE which is enabled on my G4 and obviously works in the correct mode based on my speeds 28mbps down, 18mbps up. Plus Verizon LG G2's are able to work correctly on T-Mobile's network and they have the same bands as the G4.
If my phone has the band's enabled to work with T-Mobile, namely band 2 and band 4 LTE, then why can't I always have LTE AND be able to text and call at the same time?
If anybody has an answer to this I'd love to hear it! Otherwise I'm going through with the trade (and trouble of setting my phone back up all over again).

My tip to you is don't disable any of the bands. You can enable all you want. I made the mistake of disabling thinking it would force the phone on certain bands. Then went out of town and lost all data. Somehow I remembered the command prompt line to get back into the hidden menu, re-enabled and I at least got edge...
