I purchased a used N900T this past weekend to use with my already established straight talk (ATT) account. It was initially rooted and running stock 4.4.2, I swapped out the sim card from my LG E980 and set the APN but it would only connect to HSPA/HSPA+. MMS and everything else worked fine. I did a factory reset and that did not help. I updated the firmware to 5.0, that did not help. I have now switched the service to a straight talk t-mobile sim card (which LTE works fine again on my E980) and am getting the same HSPA/HSPA+ only on the Note 3. I've used LTE discovery and it shows NA for LTE with either sim card and auto band selection. If I force it into LTE only, all bands, LTE discovery will eventually show LTE band 4 but it still will not connect (either sim). I really have no ideas on other things to try, I know the APN is correct from the G pro. Any help would be appreciated.
Also, the IMEI in the phone is different front the sticker on the back. They IMEI on the back comes up as being financed on T-mobile, the IMEI in the phone shows that it's clear. I still haven't been able to figure this out, I'd appreciate any input.

Hi, I have non rooted ATT S4 and typed the following *#*#4636#*#* on my keypad. I do not recalling changing anything at the time. However now the phone no longer picks up LTE. The menu is always saying WCDMA preferred and I cannot change this. I did a Google search and apparently a factory reset is supposed to remedy, tried that to no avail.
When I put the same ATT sim card in my T Mobile Note 3 I do get LTE. signal, so I dont believe its relating to plan issues. I obviously must have done something when I went into that menu as the S4 was working on LTE fine prior to entering *#*#4636#*#*
Any help would be appreciated.
EDIT: I actually removed my SIM card and entered the above code and with no SIM inside the S4, it reads LTE/GSM auto prl. Soon as I put my sim is sticks to WCDMA preferred. Not sure if this helps or not.
Just an update. method of elimination performed.
I just put in my wife's sim in the so called " problematic" S4 and it registers on LTE ATT straightaway. Thus issue must be APN related. on MY sim. Kicker being why is that I get LTE on my T mobile note 3 on ATT then but when I put the same SIM in the S4 I get HSP?

So did you resolve the problem. The problem is either your sim is bugged or the phone needs to be repaired.

Not sure. I wrote my observations above earlier. Put wife's sim in S4 and it picks up LTE on ATT no worries. Put my ATT sim inside the S4 and it goes to 4G HSPCA.
Like I mentioned, I cannot understand the logic behind this as when I put my SIM in my Note 3 is shows LTE but when in the S4 it dont.

Thanks. The phone is bugged or if you rooted you might have encountered a error.
Not rooted just typed in those commands.

what are you apn settings with your sim in vs your wifes.. it may be changing them based on the sim..
also what is the model number in /system/build.prop
I noticed when modifying mine with nexus to get google wallet on .. that the lte menu went away and only get 4g.. changing it back fixed it.. so something also looks at that on certain f/w versions.
Got this error message when using a TMo SIM in a Verizon G2. I've only seen one thread about this for the G2.
Verizon G2s are SIM unlocked, right? So it shouldn't be a problem? I can put the TMo SIM in a TMo branded S2 and get full bars. I even tried the same SIM in a Verizon Galaxy S3 and got full bars.
I'm on VS98012B
As a follow up, I went into available networks and this time, TMobile at AT&T show up. I tried setting it to WCDMA and GSM but it wont register on the TMobile network.
This is a location that I can normally get LTE.
The VERIZON model is GSM unlocked. Says your on 12B so you should be good. You should be able to just pop and go. I don't have much experience with it but you would have to select GSM in the Network Settings.
I have a Vzw LG G2 VS980 that I currently use with Red Pocket on the Vzw network, and I previously used it on Tracfone, also on the Vzw network, and everything worked normally.
I also successfully used it with Red Pocket on the AT&T network as well as with an old Lycamobile legacy SIM, using the T-Mo network.
The problem I'm having is that I can't get cellular data to work using a Piranha Mobile or FreedomPop Global SIM card.
There are no error messages displayed, and I'm able to make voice calls with the Piranha Mobile SIM card. The FreedomPop Global SIM card doesn't come with traditional voice service, but there are bars of service showing.
The APNs are correct:
For Piranha Mobile, I'm using openroamer.com .
For FreedomPop, I'm using freedompop.foggmobile.com .
The Vzw LG G2 VS980 is rooted, but running stock 5.0.2. I rolled it back to stock 4.2.2, but cellular data still wouldn't work with the above SIMs. I also tried a custom ROM, and still nothing.
Can anybody suggest something to try to get cellular data to work with the above SIM cards? I'd greatly appreciate it!
I should also add that I DID enable global roaming in settings, and I did play with all of the System select>>Network mode settings, to no avail.
Also, even if people reading my question don't have an answer, if you could suggest some way to contact someone that could help, I'd be very grateful. Thanks again!
Isn't there any help available for my issue? Thanks.
I sure could use some help in figuring out how to fix this problem. Thanks!
Did you ever figure this out? I am experiencing the same problem

Unfortunately, no.
My LG G2 also was difficult to get activated on Vzw MVNOs. I used it on 2 Vzw MVNOs, and both times, it wouldn't activate the SIM card properly. Both MVNOs had to do quite a bit of work to get it to activate properly. There was no issue with the ESN/IEMI, it was just that the hardware wouldn't activate the SIM card properly.
Not only that, my LG G2 VS980 developed dead spots on the touch screen in March, 2017. It's still usable, but the dead spots make it difficult, so it is mostly retired now.
Oh, well...
I'd try getting into your G2's phone "diagnostic" menu (or whatever it's called), and doing a manual band set. That seemed to help me when I put in an AT&T SIM in my vs980.
It could also be that FreedomPop or whomever you're trying to use doesn't support the network bands that the vs980 uses.
I have a factory unlocked S8 I just recieved that I've been using on Straight Talk(verizon network) and that's been working fine but I wanted to test the reception of t-mobile in some places and I can't get anything to work. I have a Flash Wireless sim that I've used to at least see if I have service on other phones but I get nothing on the S8.
In Network Mode I only have the option for LTE/CDMA or CDMA. No Global or GSM options are even listed. Does this have to do with the SIM card not being properly registered? I would think I would have a Global option regardless of SIM I put in it.

I have the same problem. I'm on MetroPCS and I bought a Galaxy S8 used on Straight Talk before. I can't make any phone calls, but I have LTE and SMS works just fine. Does anyone else experience the same issue? I really appreciate any help. Thank you.
I'm trying to use this (Zt500kl) with metropcs and it refuses to recognize the sim. No bars on the reception. Apn automatically sets itself to tmobile, and I've added metro's but that didn't work.
I've read the main lte bands tmobile/metropcs are supported and the tablet is unlocked so I have no idea why it's not working. There is an even a post on here from years ago with someone saying they threw a tmobile sim in without any problems.
