I recently bought an lg wing Korean version, and it had trouble with really slow internet and being stuck on lte band 20. It turned out my APN settings were bad. I looked upy carrier APN settings and mine didn't match up. So I typed in the correct ones and now I can connect to lte band 3 and 1 also.
Did you go into the hidden menu?
What did you modify?
Settings/network and internet/mobile networks/access point names.
Where are you located and what carrier?
What did you change it to?
Finland, apn settings are carrier specific. Look up your carrier APN settings and check if they are the same as the one in your phone settings.

Hi ,
I have Bell Atrix, unlocked, I flashed the Franch SBF 2.1.1, and all worked well, EXCEPT..
the phone is always roaming, I cannot get data unless I check the Data roaming, there is a little (r) next to my signal all the time..
and I don't know how to fix it..I checked Build.prop, to see if there any setting there.. but I dont know which and what to look for..
my question is: is there a way or a settings that I can change to get rid of the raoaming issue.
as I said my Atrix is BELL and I am with fido..
You need the apn settings for fido, and create an access name under wireless settings - network settings -access point names.

I did put the APN for Fido, unless I turn on the roaming data, it does not connect.. also now one seems to explain the (R) next to the signal.. why the Bell Atrix started to show me that its roaming after flashing with FR 2.1.1 sbf.. in on Montreal with FIDO and fido sim in my Atrix..
that is my real question.
Hi,
There are two numbers, MCC, and MNC in the APN, the phone will show roaming if what the network reports is different than what is setup.
MCC (mobile country code) for Canada is 302, you should have that.
MNC (mobile network code) for Fido is 370, if your APN isn't using that then you will be roaming.
http://en.wikipedia.org/wiki/Mobile_Network_Code
The French sbf may not have the canada codes in it's apns.conf, see attached file from the Bell stock firmware, you can replace /etc/apns.conf with that, then go to access point names and reset to default.
Cheers!

I'll take a look in my apns.conf but it must have the Canada codes as I have been running the french sbf since it was leaked on my Bell version (on Bell) and never had it roam. I just had to add the Bell apn (obviously) and it worked fine.
I do have a question for you though, since you seem to know a lot about these phones, etc. On my last phone (Samsung Galaxy S), there was a secret menu code (like *#*#4636#*#*) that would take you to the network band settings. From there you could not only see what band the phone was running on, but you could SET what bands were active. Is there anything like that on the Atrix? I am curious if the modem in these non Bell sbf's like Telstra/french sbf access the 850MHz band or not.
Hi,
*#*#4636#*#* is the only one I know about. You can set GSM vs GSM only etc, that would be where you'd change bands.
The codes would only be launching an android app/service somewhere, i tried a hex edit and file search of apps, couldn't find it.
Cheers!

Thanks for looking. I wasn't sure if you could even manually set anything other then selecting "USA Bands" in 4636. It's no big deal, i'm just used to being able to go in and manually select bands on my previous SGS.
My signal is fine, it was just for curiosities sake.
HI NF
I check my APN. here are the values
Name: FIDO
APN: Internet.fido.ca
USERNAME:Fido
PWD:FIDO
*****
MCC:302
MNC: 370
Those are the only values I have..
this is really strange.. according to the above, I should not be roaming.. but something changed in my phone when I first flashed the French SBF.. and is shows roaming after that flash..
this is really strange..
UPDATE: another problem : when I choose Setting->call Setting->Operator Selector, I notived two things.
the Check box next to Select Automatically is not there, I think it was there when I was on Bell Stock,
next when I choose .. Search Networks.. it searched for long time and phone stops responding, I have to Turn off .
also, when I choose Advanced Setting the Call waiting is greyed out, when I click on Caller ID I get Invalid SIM Error.. again I have to reboot to get the phone working again..
the info I have after *#*# 4636 ...
Nieigbouring CID shows as UNKNOWN..
Roaming: Roaming
NETWORK TYPE:UMTS
not sure if this will you a clue..
Hi,
Sounds like it might be an issue with the radio itself, or it could be that you are just roaming, perhaps a network outage. I would try flashing the telstra sbf, see if you get the same problem. If we had a Bell sbf would could revert back to the stock radio, so we have two options, 1.87 or 1.92. You could try just flashing the radio to see.
In my settings, I have it set to GSM (auto), nothing special there. In network settings, I have it set to automatic, under operator selection, auto is selected. I don't have roaming issues myself with either firmware, but I am not using my phone in your area. Could just be a network update in my area from being in the same boat.
Cheers!
NFHimself..
I followed your instructions about Restore the partitions.. and it works.. I dont have roaming anymore and data work.. you are the man!!! thanks so much for your help
it Worked!!!
I followed your instructions to RESTORE the phone and man.. I was so happy to see it work.. thanks so much for your help..
You're welcome, two times.
Cheers!
I don't see these in my APN settings.
I have a new S2 to replace my old one (dropped it), and the APN doesn't work.
AT&T sim. The APN settings I see here have those fields.. APN type I get internet, mms, internet+mms.. that's it.
How do I adjust these settings? Need to root first?
Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.
I have been having difficulty with data roaming on stock Android 7.0 (RS98821d) on the LG G5 RS988 USA Unlocked device.
Using a T-Mobile USA SIM, I am able to use the the local T-Mobile USA network in the country of United States, but when roaming to another country and a foreign network, data no longer works correctly. Data often does not work at all until I go to the APN settings (Settings ->More -> Mobile Networks -> Access Point Names) and use the "Restore default settings" option. After a period I have to repeat the APN reset to get data roaming working.
Have others experienced this or similar issues?
Back in June I had similar issues in France. I have T-Mobile and the RS988. When I first got there I was using the fast.t-mobile.com APN and couldn't connect. I switched over to the epc.t-mobile.com APN and everything started working just fine. For the network mode I was using the LTE/GSM/UMTS setting. Hope this helps.
It seems that "epc.t-mobile.com" is supposed to be the T-Mobile USA non-LTE access point. I shall try to remember to try the "epc.t-mobile.com" APN next time while roaming internationally. However, after testing the "epc.t-mobile.com" access point, LTE can be used with it and it works well.
We have a small local carrier in Southeast Oklahoma called Pine Cellular. They roam on ATT. When ATT recently turned off their old networks, it caused problems with roaming for Pine. They told my mother-in-law she needed a new phone with volte so I bought her the Oneplus Nord N200 5g as my son has that phone on T-Mobile. Insert her sim card and wifi calling and volte still don't work. Insert my T-Mobile sim and they work fine.
I took the phone to a Pine store and they lady even put in her personal sim which had allowed her to roam in Dallas (so volte was enabled) and it still wouldn't allow volte or wifi calling. She said Pine was in the process of updating their systems but she had no idea when it would start to work. They sold my father-in-law a cheap Alcatel and it works fine. I had been convinced it was something to do with the settings on my mother-in-laws sim until the sales rep tried her personal one.
Can anyone tell me what the heck was going on and why the phone wouldn't work on their network? I'm assuming it has something to do with Pine Cellular's internal settings but really WTF?
No one?
This was an unlocked phone bought from Amazon. It worked with the local Pine network, just Wi-Fi calling did not work and VoLTE did not work for roaming, but I could make and receive calls within the Pine Cellular service area. The old Pine Cellular network was GSM.
The Wi-Fi calling menu options appeared when I inserted my T-Mobile sim.
It sounds like you purchased a carrier variant (T-Mobile) version of the N200 (DE2118). Your phone model number is different than the unlocked generic version of the N200 (DE2117). AT&T operates its VoLTE network using whitelists. This means that AT&T will not use VoLTE with any other phone models than the ones they have approved on their list. Since AT&T has "shut down" 3G, phone calls can not be placed on their network without the use of VoLTE.
Only the unlocked generic version DE2117 is on their whitelist, as you can see here:
https://www.att.com/idpassets/images/support/pdf/Devices-Working-on-ATT-Network.pdf
You will not be able to use VoLTE on AT&T with that model of phone.
Wi-Fi Calling is similar to VoLTE, and operates under the same restrictions. (VoIP over Wi-Fi instead of over LTE cellular).
VoLTE is not a true standard. It relies on the implementation of custom VoIP software unique to each carrier and each device. Hence not a standard. The goverments have not forced carriers to standardize 4G like they did 3G, so the carriers have not. AT&T is using this chance to restrict access to their proprietary VoLTE implementation as a weapon to lock down phones to AT&T approved models with locked bootloaders and/or restricted software.
Many phones which support the VoLTE "standard" are not able to operate in VoLTE mode, neither with AT&T nor the other carriers. Even changing the system software on the phone can break these proprietary VoLTE implementations, as I have found personally.
It was the unlocked version. It did work on pine cellular. She could make and recieve calls on the phone network, just not roam because volte could not be enabled.
Amazon.com
In that case, there are many steps to getting VoLTE working roaming on AT&T
1. The SIM card must have proper settings in it, sometimes requiring replacement of the SIM card.
2. IMS software must be installed on your phone (the proprietary VoLTE software made by your carrier). If you are running stock software, this is already done.
3. APN (IMS) settings must be correct. It seems your local carrier is still running 3G, and you do not need VoLTE there yet, so the pine cellular APN can be skipped.
Two APN entries are needed, one for data (carrier) and one for voice (IMS).
One will be named IMS with uniform settings, the other will be named after the carrier, with specific settings.
Settings -> Wi-Fi & Network -> SIM & Network settings -> Access Point Names -> APNs
Uniform IMS settings
VoLTE－Manually add the IMS APN - SUN Mobile
SUN Mobile
www.sunmobile.com.hk
The IMS APN is not the active "checked" one, but must be present in order for the voice (VoLTE) network to work on top of the data (LTE) network.
Each carrier has specific values that must be programmed. Sometimes Apple and Google will program these settings through their management controls for the major carriers, otherwise they must be inputted manually.

Thank you so much for writing all that out. i bet it's the APN settings. There was only the one for pine and putting the sim in another pine cellular phone had it working. I'm going to try one more time before I send it back. I'm not very confident that pine customer service knows that they are doing at this point.

I guess I'm going to send this phone back and buy something from Pine. Bought a new SIM card from them this morning and it still doesn't work. I now have data roaming on ATT but still no VoLTE or WIFI calling.
The Pine rep I talked to this morning was much better than the previous one and she said she had experienced this previously with a clients new phone. Pine was "old school" with some of their internal system.
I did notice they aren't selling any 5g phones yet so it's possible it's something with this being a 5G phone or maybe Android 11.
