3g/4g network

Hi. I bought One S in USA (T-mobile version, unblocked) and bring to Europe (Slovakia). Call and SMS works well but data network does not work. Could be the reason the phone is 4g and there is only 3g network in Slovakia? Is there any trick how to solve this? Thank you guys.

Are you sure your One S supports 4G (LTE) ? Never heard that yet. There are countries in which the 3G (UMTS/HSPA) standard is defined as 4G. very confusing...
Maybe you have to set up the APN preferences. You need the right settings for your carrier.

Thanks. I tried this, no change. I see Disconnected on "Mobile network" settings.

I also had this problem, click on names access points and click on your carrier then it should find your carrier and data connection.

Could you be more specific please? Thanks.

Options>Mobile Network>Access Points and then click on the carrier you have.
When I did that my data connection started working. Even when It already had the carrier automatically listed.
English is not my native language sorry.

I had to create new APN here, nothing was listed automatically .

Yes I sow on my Korean SGS3 SHV-210S and in this menu you could change some factory settings fro SMS, GSM settings and etc., for example instruction for Korean SGS3 like here http://people.sarang.net/2963084

I want to know just for information, because for example in Korean version SGS3 possible to change setting for network priority and etc. see on picture

Maybe no one knows the codes yet.... It should be set on Automatic, My settings by default are perfect ,switches back and forth from 4g to 3g and the change is very quick, It does not lag or stutter at all. Even if there was a code i would never use it lol, But I guess google is your freind for now

Could this mean there is a hidden setting to just switch between WCDMA and GSM automatically?
I'm not yet in an LTE area so its pointless having the phone try to find an LTE connection. Currently I just have it locked into WCDMA but sometimes 3G reception is patchy and I want it to pick GSM automatically.

Maybe
Just Leave it In auto mode its not like your hurting the phone, If it receives a 4G signal it will switch if not then it wont, It doesnt waste any battery
The phone has this option in Settings>More settings>Mobile Networks>Network Mode>AUTO MODE (LTE/GSM/WCDMA <<<<<<<<< This is the default setting. It will switch bands depending what the coverage is. LTE being Priority then GSM then WCDMA
I am 90% of the time in a 3G area and I have it in this mode

*#197328640# - almost the same code as the SGS1.
UMTS->Debug Screen->Phone Control->Network Control->Band Selection would be what one would want to lock only into certain bands.

Guys may be this will be useful for somebody.
*#0*# - using this code you could enter to the hidden service menu and test all main phone hardware functions psychically

How do you go about updating PRL / profile? Is it under settings like the Gnex? Thanks! Just curious before I buy.
Sent from my SPH-L720 using XDA Premium 4 mobile app

I believe it should be possible
It uses a WTR1605L Chip and from what it appears CDMA tools should work on it.
My goal is to get one working PagePlus however, I canceled my order in fears that it may not work and will wait until it's confirmed.

Yes, it's possible.
For the curious, Settings > More... > Mobile Networks > Carrier Settings

Nothing on the user accessible settings although you can switch to LTE or 3G only instead of global and the device will recognize your carrier settings. There should be more stuff under *#*#3282#*#*

Settings-->more (under wireless & networks)->mobile networks->carrier settings-> update PRL and update Profile

Settings-->more (under wireless & networks)->mobile networks->Network mode (choose from LTE/3g/1x/Global - Global is apparently the default - phone switches to that after a profile/PRL update).

Network Type/VoLTE Problem

Not sure if I'm being stupid here....and did search but couldn't find anything quite like the issue I've got.....
I live in an area with pretty flaky LTE coverage and because of that, I struggle with VoLTE....basically it's rubbish and can't hold a call very effectively.
On my old 6T I could switch off 4G in the preferred network setting menu thereby forcing the phone to 3G and a circuit switched call.....no problem. With my OP7 Pro, I only have the option in that menu of "4G/3G/2G (Automatic)".
Is that right? Or should I be able to select "3G/2G (Automatic)" like I could on my 6T?
Or is there a way of turning off VoLTE that I haven't found yet?
TIA!

So now you have two issues. You can't change to 2G/3G and you have no VoLTE toggle. You may need to reflash latest Full OTA zip. You should have those options. Are you on T-Mobile?

Through phone app, general settings/sim&network the network type is there. Then sim settings (sim 1) toggle is there

The only option in that menu, under 'Enhanced Calling' is WiFi calling.

Well, this is weird.....have reset to factory, flashed the 9.5.7 full ROM and still have the same issue.....
I suspect their is a SIM card provisioning flag that the phone is respecting......i.e. EE have said they want the phone to prefer 4G always and therefore can't deactivate the ability to use only 3G/2G.

Go to dialer, then *#*#4636#*#*
Then choose what network type you want.

I am also on EE, EE is the only network in the UK that had volte on by default. I have spoken to them about this same thing and the reason the toggle to switch off volte is missing is because EE can't switch off volte on their end without disabling 4g too. So it's normal if using EE, if you use a sim from Vodafone for instance the volte toggle should reappear in the settings.

Question 2G on A13

Can anyone who has already upgraded a Pixel 6a to A13 tell me if the "Allow 2G" option is still available in Settings-->Networks-->SIMs ?
Some people on twitter are saying that they cannot set 2G as a "preferred" network anymore, not sure what it implies.

The option is still here yes. However, you can't set 2G as the preferred network type.

Try this..
Open Dialer
type :- *#*#4636#*#*
Click on Phone info
Select Preferred Network type & Scroll Down & select "GSM Only"

Thank you guys.
Current situation is bizarre for me. I need 2G working for voice only. My carrier is switching 3G off, and I cannot have VoLTE working (despite the corresponding option being enabled and carrier saying that it should work). Currently, when I make a phone call, the 4G data connection gets disabled and voice travels over 3G or 2G. When the phone call is over, 4G data connection gets back on. Since 3G is being switched off, if 2G suddenly became totally unavailable, I simply couldn't make phone calls anymore.

I believe you can get a number with Google Voice, and call thru the app. I haven't used it in a while tho.

I think that probably depends on the carrier, because with my other carrier I have this options:
5G appears now, but I just guessing

I used "Toggle Network Type" app on earlier android, but not it can't set 2G as preferred type anymore.
Edit: actually it was Automate app that I used, but neither it nor Toggle network type work.

Not sure if you have tried enabling this option in the SIM settings (something to do with the Tensor Security settings as Google deem 2G to be less secure.

I didn't, because I don't have it. I'm actually on a different phone and rom, and just trying to find a workaround, this is the closest thread to my problem that I found on xda. I'm using Samsung S8, and this rom: https://forum.xda-developers.com/t/rom-13-crdroid-android-9-x-for-samsung-galaxy-s8-s8-n8.4516883/
