Hello, I am currently living in Toronto and would like to test the network coverage for WCDMA 850MHz only, because the phone I'm buying only supports WCDMA 850/2100 (my carrier uses 850/1900).
I tried using *#*#4636#*#* but this only gives me the option to switch between Japanese, USA and cellular bands and does not allow me to distinguish between individual bands.
I've tried googling this and no help has come up yet.
I'm currently on Purity 4.4.4 and Hell's Core.
I have the same issue. Traveling in India, and my US-bought Nexus 4 seems stuck on US frequencies. My coverage and signal strength are terrible and the phone can't hold a connection. I want to switch it to Indian frequencies.
I tried using an app called Radio Switcher which is just a friendlier way of accessing the hidden menu. However, under Select Radio Band, it only shows USA and Japanese bands, not Euro or Asia.
Running CyanogenMod 10.2.0-mako.
Is anyone having their phone service (calls and data) drop when using 4G?
I have tried every combination of 3 SIM on different networks (O2, EE and Three), each one in each slot, each pair in both slots; when limited to 3G all SIMs work fine and have full, stable connections. Every time I set either SIM slot it be 4G preferred, phone and data for that SIM will drop every few minutes. Before the update I got a "no service" notification, now the bars show as empty. Before the update the connection would come back, go back to 4G, and then drop out again after a short time; after the update the signal comes back but the connection often stays at 3G (and data + phone stay fully connected.)
I have tried this at two locations 10 miles apart, and a few stops in between.
Is my handset broken, or is this software related and all similar users have the same problem?
Thanks.
Could be that your location has a weaker 4G signal or that you have LTE ONLY mode on in another setting/module.
I have had no issues with 4G connectivity, and that's likely because I have a strong reception at my location.
If you haven't already, I'd suggest checking details of your connection through a 3rd party app such as LTE Discovery (available on playstore). Though Googling for LTE Bands supported on XT1643 brings up several mentions of it supporting 5 bands (including the faster 2300MHz band 40) while checking the inbuilt Motorola program menu LTE settings, I found only four listed, 1,3,5,8, which I haven't yet probed on. Going by my ul/dl which maxes out at 6/17 megs, and my carrier offering bands 3,5&40, it looks like I am one of the first two.
Another option could be using the OpenSignal app and checking for how you measure for different protocols, signal reception and latency, all of which are decisive in how your phone goes about switching and selecting network. As for the compatibility, Moto G4+'s Snapdragon 617 SoC has LTE support baked in, as has been the case for past several Qualcomm chips. So unless, all factors such as network settings, signal strength and carrier configuration have been tested to be optimum, it doesn't look like this is a device related issue.

Thank you for replying, it seems like you misunderstood me, I'm not talking about the data connection, I'm talking about the standard signal.
Even in 4G preferred mode it will scale down to 3G, so it's not the data signal that's at question, why would the standard phone signal drop or completely go ("no service") i.e. no calls, only when 4G preferred is selected?
Bump for the recent update to the OP. Thanks lovely people. 10chars
inbuilt Motorola program menu LTE settings?
How did you access the inbuilt Motorola program menu LTE settings?
I have a Moto G4 Play and am having a hard time finding this menu!

I have a problem with the Samsung Galaxy S8 unlocked, carrier-free USA version (SM-G950U1) and the way it interacts (or fails to interact) with certain cell towers/bands/frequencies while trying to connect with T-Mobile.
Inside some large buildings, it doesn't get a signal. What *appears* to be happening, based on my limited knowledge of these things, is that the phone can't see/maintain a connection to any LTE or GSM signals, and keeps defaulting to CDMA.
Other phones DO have service at the same time and place, *including* my Galaxy S5 with the same T-Mobile sim card that I'm trying to use in my S8. I can take my S8 outside (or into many other buildings) and it maintains an LTE/GSM signal without problems. The trouble spots are consistent, so this is annoying to debug because I have to go to certain places, but once I'm there, the problem reliably happens.
Since my old phone with my current sim card still works in these same locations, I don't think it's exclusively a carrier problem, and is either a) something wrong with the phone, or b) something wrong with the interaction between T-Mobile and the unlocked Galaxy S8. Because I can't find discussion anywhere online about option B, I've been assuming it was option A. However, I've tested 2 S8's so far and both had the same problem, so now I'm not sure what to think. I've just picked up a third S8 that I'll test in the next few days.
All the S8's are running the latest stock Touchwiz software and are not rooted.
Does anyone know enough about these things to help? I'm attaching screenshots of info from the app LTE Discovery - all tests are using the same T-Mobile sim card except in one case, as noted:
** (QA) S8 at location "V", with no LTE and a HSPA+ signal -103 dBm. It appears to be connecting to/only see CDMA towers.
** (QB) S8 at "V", with no LTE and a GSM (?) signal -97 dBm.
** (QC) S8 at "V", with a VERIZON sim card that I briefly borrowed to test with, with LTE on band 13 with -108 dBm and a CDMA 1xRTT signal at -96 dBm.
** (QD) S5 at "V", an LTE signal on band 4 with -113 dBm and GSM -69 dBm.
** (QE) S8 at location "P", with no LTE and a HSPA+ signal -99 dBm. It appears to be connecting to/only see CDMA towers.
** (QF) S8 at "P", with no LTE and a CDMA (?) signal -89 dBm.
** (QG) S8 at "P", with an LTE signal on band 2 (through a CDMA tower?) at -130 dBm. The cell radio is "connecting" and it sees a bunch of LTE and GSM towers that it apparently decides not to use...
** (QH) S5 at "P", an LTE signal on band 4 with -113 dBm and GSM -75 dBm.
What on earth is going on? Anyone else experiencing this? Your insights are appreciated!

US Unlocked S8's model # is: G950U1. I have the same model and used it on T-Mobile for about 2 months before flashing firmware on it. My work building has Band 4 and Band 12. There are spots in the building where phone would have low Band 4 signal, then would connect to Band 12. I haven't seen any weird behavior of the signal in my building. The reason I keep bringing my building as an example is because it is very tricking for phones without band 12 to properly have signal there, at least on T-Mobile.(haven't checked other carriers)
Then I flashed my phone with T-Mobile firmware and continue to have coverage as I did when my phone was running an unlocked firmware. You could flash your phone with T-Mobile's firmware which will give you all T-Mobile features, but will also give you few of their apps, but they can be disabled.
If you decide to flash the phone, use "flashing standard firmware" option - https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817

Thank you! So you think the S8 isn't properly connecting to band 4 or 12, and that could be the problem? It does look like it might only ever be connecting to bands 2 and 4, so if it doesn't by default connect to band 12, maybe that is the problem. Although my S5 connects to band 4 in both those spots, but my S8 doesn't, so I don't know if band 12 is really the issue.
I have the unlocked AQH3 firmware and bootloader installed now - I assume this is the "XAA" version? If I try flashing the T-Mobile version of that same firmware release, should I expect that to change something about the network settings/capabilities that I can't otherwise change? And this does not require root, correct?
Thanks again!

Root isn't needed.
I don't really know what changes it will bring as far as networking capabilities, but if it is the T-Mobile firmware, then it most likely be very well suited for its network. Unlocked model still connected to band 12 and I don't know if your city or place has band 12, but you can easily find out by using LTE Discovery app and it will show you. Flashing to T-Mobile firmware gave me the ability to place "video call, have advanced massaging and has DIGITS service build into the phone app" + some people also mention that 4x4 MIMO and 256 QAM are also supported on T-Mobile's firmware + I have read stories that they got better signal as well.
An update, for anyone else having this issue: my best theory has been that the phone was prioritizing non-LTE signals over a weak LTE signal. How I fixed it the first time: enter the BAND service mode via the native dialer by dialing *#2263# (2263 spells BAND). Clear all bands, then select all LTE bands (ONLY LTE) and apply the changes. This forces the phone to use only LTE signals, no matter their strength. It's worth noting that you may need to alter this when traveling through areas without LTE service, by re-entering the menu and selecting all bands and applying the changes.
My phone *just* updated to Oreo, and the problem may be back, although I haven't had a chance to thoroughly test or debug it, yet...
I use Ting, and LTE is available in my area (wife's on same plan) I lost my LTE/4g after flashing Cosmic OS. I've been struggling along with 3g just fine. The phone never showed CDMA - always showed "Global" in the network settings, if I Switch to LTE preferred I lose my signal and have to reset my network settings.
I ordered the MintSIM test kit, and installed it today...and I had LTE. Mint runs off of T-Mobile, Ting runs off of Sprint.
My LTE isn't gone... it's just gone from the CDMA side of things.
Has anyone else flashed Oreo onto a Sprint networked phone and retained their LTE? Is it something with the current ROMS and Sprint?
Experiencing the same after flashing FrankenRom.
Don't get LTE with Tello but I get LTE fine with redpocket T-Mobile.
Hi guys,
I just got a Nokia X6 on Android One shipped from China and for some reason it defaults continuously to H+ instead of LTE on my Cricket network. On my Network Type option in the Setting In only have 3 options 2G, 3G and 4G and I have 4G selected, but still H+ is being used by default even in areas where I used to get full LTE signal.
I have tried however to get into the Android Testing Menu (by dialing *#*#4636#*#*) and change the Preferred Network Type to a few options like LTE/UMTS auto (PRL), but for some reason is the H+ that is picket all the time. even in areas where I know the LTE signal is strong. If I select "LTE only" from that menu, then I'm getting on LTE but as soon as I go into weak signal region, the signal drops completely, while not the same thing I can say about the other option, when the H+ connection is present in the same weak signal area.
Another thing that I see in the Android Testing Menu is that my VoLTE provisioned option is Off and I can turn it on.
Do you guys have any ideas on how can I get this device connected to LTE when the signal is strong?
I have a Nokia X6. I put two SIMs into it, both show 4G.
I have some problem to connect data or mobile internet. Grammen phone provider.
I was ready to purchase one, however, was curious if this would work on t-mobile. If so, would the Wi-Fi calling work?
Did you already checked if your 4g network band compatible with your phone?

So, have you solved your problem?
If the ROM of your phone is "CN" you could try to flash the phone to the global ROM 2_29(WW) or wait for a new update of the firmware. You haven't noticed the firmware's version. Have the phone got any updates?
I just returned the phone and got an LG G7 instead. The X6 that I was using also had a problem with Bluetooth as I was never able to turn it on.
Manually switch the preferred network type.
I am using the latest Stock Android version on Nokia 8 and struggled with this issue too. I tried everything I could possibly do.
The simplest answer is to go into network settings and select 2G, give it a minute to find it. Do it for 3G too. Give it a minute to find it. Then 4G, same thing. Finally select 4G as preferred network type and that should do it.
It looks like the default preferred network type is 3G from the factory.
guys i cant even access my mobile data connection can anyone tell how access it
thanks
