where do you live, do you have a lte plan and a lte sim?

Update:
I have come to the conclusion that the 3G and LTE modul might by fried, so I'm sending it to warranty. Anyway, thank for your concern!
I live in Romania and I have a fully working HSPA+ plan.

no way 3g module would be faulty, its the same piece (the whole cellular thing)
go to your carrier first, see if they need to configure something(like apn or so)
there is also the hidden menu(dont remember how to open it, search on google) where you can change some signal options

Roaming

Hi,
Have a big problem in that whenever I put a rom on my new Tilt 2 (which I am running on the new HSPA Bell network). My phone thinks it is roaming.
This is a real pain and I can't seem to find away around the problem.
Please can somebody think of something I might be missing?
Thanks!!

Are you sure its roaming and not mistaken the icon for something else? Also, if you are indeed roaming, which network is it? AFAIK, in ON, there's only 2 HSPA network Rogers/Fido or Bell/Telus. Who is your provider?

So I have the icon telling me that I am roaming and all the application warn me before they download data that I am roaming as well (which is a right pain!!).
I am on the new Bell HSPA network.
Any ideas?
roaming..
ok .. this is my experience about this problem ..
first my home base is Netherlands ! and im using Telfort network on my nokia .. buat the last 3 year .. Telfort using KPN Network .. if you turn ON the phone .. it will display Telfort .. but a few second it will change to KPN ...
maybe.. your operator also using another network...
if I put my Telfort sim to TP2 it will display Telfort but with with ROAMING icon !!!
cheers

Bell have their own network here so I dont think that could be the problem. I also have a Omnia 2 and an Iphone 3Gs that dont have this problem.
Also just tried to manually join the Rogers network and as I thought it would not let me connect.
It is only on the tilt2 after I flashed a new ROM onto it.
Thanks for the idea though.
Anybody else?

EDIT: read this first and then try the following suggestion
Try setting in the TP2 band selection to only HSPA and see what happens. Since bell has no GSM, and if your phone is set to 2G mode only, it's falling back on Rogers/Fido, hence, the roaming.
Start>>Settings>>Personal>>Phone>> Goto "Band" tab>>Set the GSM/UMTS band to "GSM (1900+850) + UMTS(1900+850).
Play around with the Network type by switching to GSM only or CDMA or leave it on Auto.
FYI Rogers/Fido and Bell/Telus HSPA network runs on 850/1900 band.
Food for thought....
Also another thing to consider, considering that Bell/Telus HSPA network is new, I thought i read somewhere you have to get your device "added" to their new HSPA system. Right now, only new sign-up's gets on the new HSPA network. In other words, your phone is trying to get on Bell HSPA network, but Bell rejects it since it's not in their system, so your phone hop's onto next on the list, either roaming on Rogers HSPA or Rogers GSM.

Thanks for the detailed response.
I dont think I am on the Rogers network as I get the Bell operator logo appear and the phone stays on 3G (as I cant drop to Edge because Bell dont have it on their network).
Also checking my online billing from the past few days I would expect to see some nasty roaming charges which I dont have.
Finally I also have a Jailbroken Iphone and that works on the network fine without any problems.
Its just very weird!!
Just tried to connect to the Rogers network manually and it will not let me connect. So it must be something wierd on the device.
Oh, it does show Bell operator logo. I thought the phone was registering on another entwork other than Bell.
Hmm, since you are not incuring roaming charges, only thing I can think of, is the network list that comes within the ROM classifies Bell as CDMA and not updated to reflect it supports HSPA. So it reads the network id as Bell and network type as HSPA and thinks its roaming? I dunno, i could be wrong lol! ::shrugs::

Make sense to me
I guess I can live with it if I need to. Does anybody know of a way to force the device not to flag any messages about roaming?
At least that will make it less annoying.

Please answer asap

I'm leaving for NO, LA tomorrow. I need my phone to be reliable. My issue is the phone drops signal often (T-Mobile US Prepaid) but it says it still has full bars and 3G/H+. SMS, MMS, internet and sometimes even calling all fail until I reboot my phone. I am on OmniRom Kitkat. This also happen on stock ICS and JB. Would switching APN settings from T-Mobile US (epc.tmobile.com) help at all? At least for calls and texts? I have 5 options. Simple(APN simple) StraightTalk T-Mobile(APN wap.tracfone) T-Mobile US(APN epc.tmobile.com)
T-Mobile US LTE(APN fast.t-mobile.com) and T-Mobile US LTE IPv6(APN fast.t-mobile.com). Would any of these make a difference? Or can I force roam on ATT and would that help? I bought a new sim but that didn't fix the problem. HELP Please!

This phone is missing the AWS/1700 band support for T-Mobile. If you are on prepaid, then you should try getting AT&T compatible MVNO.

The 1700 should only effect data. And even that isn't entirely true because my area is refarmed to 1900
No. T-Mobile 3G supports both voice and data.
T-Mobile 3G (HSPA)
•With 3G, theoretical maximum download of 14 Mbps.
•Our 3G network operates on the 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 3G network.
•On our 3G network, you can use voice and data services simultaneously.
UMTS/WCDMA is technically capable of both voice and data.

[Q] Nexus 6 4G Issues

I am having issues with the 4G on my Nexus 6.
I live in the UK and I am about 150 Yards from my nearest Tower. I am well within a 4G coverage area but I get no 4G connection.
I am using the Carrier Giffgaff a subsection on the O2 network.
I have a 4G sim with a 4G package so I know I should be recieving 4G. I am waiting for my carrier to get back to me on my issues.
I was just wondering if anyone could suggest anything that may help.
I have rebooted my phone multiple times.
I have cycled Data on / off multiple times
I have cycled through Airplane mode.
I've switched the network to 3G only and back again.
In phone dialer do this: *#*#4636#*#*
Then choose what you want to connect with.
what is 4G? what kind of signal are you talking about? both hspa+ and lte are considered "4G". 4G is just a term that data providers use, its not a real signal.

if you dial *#*#4636#*#*, then press phone info, you can set your radio as lte only. after setting lte only(you wont get phone calls on lte only btw. it needs to be set to lte/gsm or lte/cdma/gsm to get calls as well). if you get no signal on lte only, then you either dont have lte in your area, or you need to talk to your provider.

No such luck im afraid. But according to my provider pages there's a small percentage of customers 1 in 1000 with the inability to connect to 4g even when fully set up and standing directly next to the mast. Seems to be an ongoing issue for the last month. Maybe I fall in that category just need to wait till they respond.

Are you with o2 by any chance? I'm having the exact same problem. I'm in the UK as well and haven't been able to get LTE/4G at all since I put the sim in my Nexus 6. Could get LTE almost everywhere with my Note 4.
Ask your provider to give you a replacement sim or at least go and try one in a store that is in a 4G area. This will if nothing else rule that out.

SM-N950N CSC change

So i bought the N950N version from SK (kt branded) is there any way to change the csc to multi? I live in italy so i need the ITV one. Im asking this becuase the mobile data icon stays on 3G while on my S6E+ chamges to H+ (don't have 4G acrivated because of reasons). The speedtest also shows a big differnce in DL from the 2 phones.
Thanks in advance

I don't think the CSC change would help you as your issue is with the radio which is in CP file. It is not an icon or preinstalled apps as you have described. There was a speed difference so it is most likely a 3G band compatibility issue.

The bands are the following, may not be exhaustive though.
2G/3G 900/2100 MHz UMTS, HSDPA, HSUPA, HSPA+, DC-HSPA+
4G 1800/2600 MHz LTE
The rom i was talking about it's the original firmware that can be find on sammobile; can i flash it? Dovi need root permissions in order to flash it?

You won't be able to flash a 950F firmware with Odin, but you can install TWRP and flash a ROM in a zip file that way. Root has nothing to do with this method because the entire system is replaced.

Sorry to bother ypu again, went on device information, under sim status and noticed that it is actually HSPA+. Could this mean that is just the data icon not changing but it actually connects to H+ network?

yes, the icon displayed is based on which CSC is loaded. HSPA is technically a 3G technology, so some companies display it this way. Some companies call HSPA+ 4G, and some call LTE 4G.
Can you download the app LTE Discovery and see which type of network you are connecting to?

Hi, I am new on this forum and I reached here searching for the same issue.
I bought a galaxy note 8 SM-N950N, single sim, 64 Gb it’s the korean model.
Since I am italian and soon will go back to Italy, I’d like to know if is it possible to flash a stock italian or at least european rom.
And if you have any suggestion about which one should I use, for the moment I understood that I should flash the twrp and then put a zip file with the rom.
Is it possible to do it also without triggering the knox?
Thanks in advance.

Go to settings, general management, reset, then reset network settings. You will have to re-enter WiFi passwords though, but hopefully that will fix it for you

That's strange, I don't have a problem and I didn't change the CSC for it. I think there are some threads here on how to change the CSC from a 950N, but you would have to root the phone. I haven't done that so I won't be a help in that. Good luck, and let us know if you get it sorted.

Question SM-G998B no carrier aggregation, help needed

So i bought a sm-g998b (s21 ultra) from australia (telstra) and came to estonia, and here i dont have any carrier aggregation, volte, vowifi, doesnt work, no 4.5g, no 5g, i tried switching bands to european but it says unsuccesful with all of the bands, is there a solution for my problem? eg changing out the firmware or something else?
Everything is absolutely normal - a quick Google search would have told you the same.
Estonia doesn't have a 4G network (*country coverage is approx 2% for 4G).
- You'll have a few 4G cells in the center of Talinn
- Since 3G doesn't have VoLTE (LTE=4G), everything is in order.
- VoWIFI won't work either, because *most* of the time, the wifi network must be on your carrier broadband box.

You're wrong. Even your link shows, that the coverage percentage is definitely higher than 2%, in addition to the fact that this map only contains community-provided data, which might not cover all areas.
All 3 telcos in Estonia have about 99% of coverage of the whole country, two of which (Telia and Elisa) also support VoLTE for certain phones and Telia (also building 5G using DSS) supports VoWiFi.
You can take a look at CellMapper [1] and see, how many 4G towers there actually are in Estonia.

you are completely wrong, estonia have had 4g+(lte-a) since 2011-2012 and coverage is 99.9% of the whole country, i have had volte and 4g+ work on my xperia xz3 since 2012-2013, i have local sim btw, i am from estonia, 2% can be for 5g rollout but thats not the issue right now, issue is i dont have any carrier aggregation on my s21 ultra and on my gfs s20 ultra, i have mine flashed with odin to SEB latest firmware but that did not resolve the issue, when i go into mobile data service menu it only shows one tower connected there and i already talked with my service provider they said that i should have at least 13 masts covering my location with perfect visiblity + all bands covered so i should be getting at least 6-800mbps (according to their test they ran on my location, yes my isp is doing tests on actual on site locations to help clients), so if anyone has any ideas as what could be wrong or should i flash any other rom on it or something? i am out of ideas, i though firmware flash would fix my issue
