Hello. I have an SM-G925F which I bought from Telekom Macedonia and I am still using my number from there also but I am currently in the US and would like to use it on T-Mobile USA.
I know that the device supports all the same bands as the SM-G925T model.
The problem I am having is that when my phone is set to LTE/WCDMA/GSM in the Network Mode settings, I do not have any data connection at all, only when I make a call, I start to get a data connection but only 3G/H+. If I switch my setting to WCDMA/GSM, then I get a data connection at all times like normal but it still is only 3G/H+. I have tried two different APNs and different settings in the APN but I still cannot get a data connection at all times on the LTE/WCDMA/GSM setting and I cannot get LTE/4G at all.
After contacting T-Mobile, all they came up with is to try to have the same software reinstalled on my phone. Does anyone have any experience with this and can anyone help me?
Anyone?
Call Tmobile and have them input your phone's IMEI in their system. Ask for the APN settings as well. I am on the same boat and one call to ATT got me from H to 4G. Your phone will just show 4G, not LTE but you will get LTE speeds regardless.
I tried doing that too. I called T-Mobile a few times and they confirmed my IMEI number being on the account but still no luck. It's really weird..sometimes I get 3G/H+ on the "LTE/WCDMA/GSM (auto connect)" network mode setting on the phone but most of the time, I get NO DATA connection at all..only the signal bars.
Any Update
Did you finally figure it out? Is LTE working now?
I love this phone....there, I said it. But it's driving me crazy.
I bought it from a Chinese retailer, who shipped it with X821 firmware, but the box states that it's an X820. I doubt there is any difference in the hardware.
I would have left everything as it was, but I can't seem to make phone calls (don't have a data plan yet...yeah, I know....) with anything other than 2G, and that is about to go extinct. When I set it to WCDMA, it shows a UMTS connection, with no carrier designation, but the tower is the same one I connect to with 2G. The phone does sometimes show an AT&T 3G connection in the status bar, but I can't make calls, even though I have full signal. When I place the same SIM in my old HTC Inspire, the same monitoring app shows "UMTS - AT&T HSDPA+" and works just fine.
I'm at my wits end. I have rooted, installed TeamSpain recovery, replaced the firmware with the X829 and even tinkered with the frequency configurations through DFS Studio (which did a lot of complaining, and I'm still not sure if the changes stuck 100%). I also played with APN settings and tried the SIM in different slots, both alone, and with another SIM. And after all of that, still no progress in getting this phone to use a 3G or 4G connection to make calls. If I don't set it to "GSM only", no phone calls in or out. I'm essentially right under a tower, so signal shouldn't be an issue.
If anyone is using the same provider in the US, and is not having these kinds of issues, I'd really appreciate hearing what firmware you are using, and/or what you did to get things working.
I am using it on x820 with official stock 0.17s firmware, and did a dirty flash to cuoco92's 17s firmware. Everything works including HD voice calls, and full LTE.

I tried this, as well as the Remix ROM. In fact, I think I've tried just about everything, without success. At one point, I had one of the apps indicating a 4G connection, but the phone diagnostics showed GSM (2G). Even the apps aren't all sure what to make of what's going on with the connections reported by this phone.
Currently on the cuoco92 v35 ROM. When WCDMA is enabled, I see simply a good UMTS connection , sans carrier name, in the "Network Cell Info Lite" app, and no ability to make calls. I also often (but not always) see the "AT&T 3G" sign. 4G or LTE never shows at all, even though the diagnostics show that the phone is communicating with an LTE transmitter, when preferred network is set to "unknown". It won't even let me set things like "LTE only".
Any chance you could set your phone to WCDMA and see what the "Network Cell Info Lite" app shows you? Anyone else with this phone on AT&T?
BTW, I am now using a data plan, which I thought might make a difference. It doesn't. EDGE data only for me . New SIM card is on the way, but my hopes aren't high.
Is it possible for a Chinese seller to have borked the phone so thoroughly with their x821 ROM (it's an x820 marked phone), that it keeps any subsequent radios from flashing properly? I don't know how/why it would work for some and not others.
Starting to really dislike this "phone"......it's more of tablet at this point.
Thanks.
I think APN is not set for AT&T
try this:
"Main steps
To use data services on our network with a non-AT&T device, you may need to program the data settings. The sections below provide the correct settings and steps for programming based on your device type and operating system.
.
Access the Settings menu.
Locate and select Wireless & Networks or More Networks.
Select Mobile Networks.
Select Access Point Names.
Locate and select the option to add a new APN. This is usually accessed by a + symbol on the screen or by tapping the menu button.
Program each field using the settings below.
Save the changes to return to the APNs menu and select the new APN.
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC
MMS proxy
MMS port
MCC 310
MNC 410

Thanks, but I wish it were so simple. I have tried this, and other APN settings. None work to get this phone to be usable on anything other than 2G.
I just received and activated the replacement SIM. Still no improvement. While typing this, I have Network Cell Info Lite app running, and with the Set Preferred Network Type showing "Unknown" in the phone's diagnostic screen, It will switch randomly between "EDGE AT&T" (which works fine) and "UMTS -" (which is useless). Both have strong signals. For a split second before it switched to "UMTS-", the app showed "GPRS AT&T", but only for a split second before it kicks over to "UMTS-".
I wish someone using this "phone" on AT&T in the US, would run this app to compare notes. It may be that that the phone works fine on a full implementation of LTE (i.e. in locations where AT&T have already deprecated 2G) but not in other areas. Still, that doesn't seem to explain why this phone seems unable to register on the same 3G network, used easily by my other phone, with the very same APN settings and SIM.
You would have to call att and check if they turned our phone on to use lte. If your phone is not "registered" as an LTE capable phone it wouldn't be able to pick it up. This phone has all the bands needed for AT&T because I am using it now. All LTE work straight out the box, and i'm on the latest 19s cn rom

I'm a bit confused. Is this what you did to achieve proper function of this device? I.e. calling AT&T and getting them to do this for you? My conversation with their tech person didn't seem to bear fruit in this regard.
Also, which slot do you have the SIM card in? I've used the stock 17s and now on cuoco92 v35 ROM. There definitely seems to be a difference in how the network settings behave, based on the location of the SIM. At one point, after selecting BAND 6 (when it would let me), the phone showed a constant "AT&T 3G" connection, but it was useless. No calls and no data.
Hi guys,
I own a Japanese Z2, originally by docomo (SO-03F) and flashed the English firmware I found in this forum (not sure for which area tho), except obviously the modem which I needed to use the docomo SIM.
I came back to Europe, unlocked the phone through an online service which worked fine but none of my SIMs can get a signal or behaves very weirdly.
I tried flashing the modem from the ROM I used before but then I couldn't get any reception and looking for networks through settings didn't show anything. With the Japanese ROM modem, I can find networks if I look manually but I can't connect to them. It shows "Selected network unavailable" and or "Can't connect to network at this time." after selecting the correct one.
I tried fiddling with the settings, different network types etc in the normal menu and in the one accessible through entering *#*#INFO#*#* but nothing helped. The phone number in the menu is shown correctly. As preferred network type, LTE/GSM/CDMA auto (PRL) is selected.
I have an older sim card in the right format which can't connect (works fine in other phones) but SOMETIMES I get like 2 bars for a few minutes. It's for phonecalls and SMS only. The internet only card I have is smaller so I need an adapter and won't connect at all. Is there something I can do about this?
Thanks a lot!
I am unable to receive any incoming calls in GSM/WCDMA/LTE mode, after 1-2 hrs of standby. Data works fine but calls donot come through. The IVR says that the phone is switched off/out of network coverage area even though i have 4 bars of signal. I have into the hidden menu trying to activate volte feature which is by itself not present in settings. Still no effect. I have also changed sims, changed operators but the issue persists. Can anyone please help!

What V30 variant do you have, what carrier are you on? When you changed SIMs, changed operators was it still the same underlying network (like two different MVNOs that both use AT&T, for instance) or two completely different networks (AT&T vs T-mobile).
Are you on Nougat or Oreo. Have you recently flashed a different KDZ to convert your phone to something else or are you completely with original firmware?

I have LG V30+ H930DS Indian software version- V10f-IND-xx. I am on Idea Cellular network. I have tried changing the operators and keeping the same operator but different number.
Currently my device is on 7.1.2 Nougat using original firmware. I did not flash anything.
Hey everyone
I have the Canadian variant of the LG G5 (the H831) and I have no LTE option in network mode.
I bought this phone from WIND Mobile (now Freedom Mobile) and it seems like they Disabled the LTE functionality for some reason.
I was wondering if there is a way to enabled it?
I inserted my SIM in my friends phone (same model but with Rogers Wireless) and the phone downloaded the APN settings from Freedom Mobile.
That did not work at all and the phone was stuck on 3G just like my phone.
I heard if I install the firmware from another provider, it might work. However it seems the APN settings from my provider are causing the LTE option to disappear from network mode.
Lastly, I accessed the service menu by dialing a code in the dialer and I was able to enable LTE.
However, I was not able to make and receive phone calls.
Did anyone here have success enabling LTE with this model or similar?
suggestions are greatly appreciated!
