I have a Verizon branded SM-G970U (unlocked) using Consumer Cellular. Icon shows 4G LTE, but when making calls, automatically switches to 3G. Also, no VoLTE in settings. CC reps say phone isn’t compatible with 4G, but having a hard time believing that. Any suggestions? Would flashing firmware with a newer version make any difference? Any help appreciated.

Ok, so a little background...
I have a Motorola Atrix 4g (Live in the US). It is on AT&T.
I have a Verizon Wireless 4G Sim Card (I want to use this instead, as I don't pay for this one).
What I've done so far:
Unlocked the phone with a 3rd party code (it said successful)
Rooted Atrix 4G
Installed an unknown sources fix (to add the ability to install unknown sources)
Installed GingerBlur Rom
Basically what is happening is this:
I put the AT&T Sim in and everything works fine.
I put the Verizon Sim in and I get no signal for 3g/4g/edge/whatever or phone.
I'm assuming I have to change the APN (but I have no idea how to do this, what screen it's on, etc...)
I'm assuming the reason I can't get connected is I can't access a temp network to do a *228 and activate the verizon service on the phone.
Any suggestions or pointers would be greatly appreciated.
Thank yoU!

As far as I understand, you have a phone which is supposed to work with GSM (AT&t), whereas you are trying to use it on CDMA (Verizion).
These two service providers use two different technologies to deliver their services, and these technologies require different types of handsets(GSM receiver for AT&T, CDMA receiver for Verizon).
So this is the reason you are not getting the signals for Verizon in an AT&T phone!!

Well that blows I was under the impression that the new Verizon Wireless 4G SIMS were GSM? Also the Atrix is supposed to be quad band, doesn't that mean it does it all?
Well that does shine some light on it for sure, I was getting two companies when I did a search for networks (Tmobile and AT&T).
Thank you very much for the response
Is there a workaround or any suggestions to get everything functional such as calls etc.
As of now only data works but you can't receive or send out messages,make calls etc.
When connected to H+ everything works flawlessly and the carrier shows, when connected to LTE only data works nothing else and the phone can't identify what carrier is being used.

UPDATE:
The issue seems to be that Verizon by default is locking the GSM radio. Users are reporting the same in the Moto X and Droid Ultra forum. Users using 4.4.2 on T-Mobile with a Verizon device.

I thought verizon was forced to sim unlock all their lte devices?

They are SIM unlocked as I'm using one but it seems the band we need for LTE isn't playing well.

Was curious if anyone else was having this issue. Any thoughts that it might be related to skipping Verizon activation? When I got the phone, wasn't activated and on first turn on it prompted activating Verizon Sim but I exited out and just popped in T-Mobile Sim.

AFAIK, LTE (unless the carrier is using voLTE) is a data only network. Verizon uses LTE for data and CDMA for calls and text.
Verizon seems to only allow GSM/UMTS or CDMA/LTE on the M8 at one time, there doesn't seem to be a true Global mode that allows GSM/UMTS and LTE to run at the same time.
That would explain why people are reporting either LTE or calls/texting (which, as above mentioned, only works on 2G/3G (be that CDMA or GSM))
The question is, is there a way to get around this? On the S3/S4 there was an app called phoneinfo which showed more modes than the Mobile Network settings menu. Is there such a thing for the M8?
This is quite disappointing news for me, since this is the first Verizon phone I'm aware of that has the 1800MHz LTE band, and that's the band used in Australia where I'm headed soon. I was excited about being able to finally use LTE there! I guess I'll have a choice between LTE and calls/text like all those in this thread using T-Mobile.

Hoping the best that this would be the fix for the GSM
while you edit the data as well I believe
Will never get 4G LTE on any other carrier besides Verizon in the US. Never have. Never will. Those radio bands are blocked at chip level.

More than likely it is same as Verizon. Won't happen till they have voice and data both over AWS network. Currently on Verizon data is on LTE and voice is on CDMA. If can get into signal settings may be a way to lock the voice section in. It is not on LTE. Verizon has had the two linked since TBolt. Others have had a problem doing this. Has to be able to do dual band at same time. Also shouldn't get LTE at all if not in T-Mobile AWS area.
Unless T-Mobile rolls out voLTE and the M8 is compatible, the VZW M8 won't work for both call/sms and LTE data simultaneously. The other solution would be figuring out a new mode that allows LTE and GSM/UMTS to work together, maybe a software update will do that, but something tells me VZW isn't running to make our lives easier in this regard (Unless they start offering international 4G LTE roaming, then they'll have to fix this issue - and that might be on the horizon as this is the first VZW phone to have LTE bands that VZW doesn't use nor has any plans to use, such band 3 1800MHz)

Hello guys
I tried searching for this problem but got nothing that would help, so am posting here.
Issue:
I recently bought LG G3 from someone. The phone is unlocked to work on all networks (AT&T branding on the rom exists though). I am using it outside of USA and it works fine. However I am unable to get 4G speed on my 4G enabled sim. I tried this sim on other phones, and other sims on mine. It is evident that it's my phone that is not supporting the 4G speed, despite showing the 4G logo up top, when data is enabled.
Things I've checked:
I have checked the bands (1800) that my model support and verified it with my network to confirm that it should run their 4G service.
The phone is not rooted.
The sim is functional and has no lock on it.
Checked with hardware checker apps to confirm that my phones supports these bands.
I am not sure if it should root it, or what. I would really appreciate your guidance on the matter.
you need u-sim and 4g data plan for make 4g work, check if u have all of this.
Hello
Yup, as mentioned in the details, I all of that.
Make sure ure apn is for lte or 4g i got stuck with a old apn from my provider once and only edge speeds
Hi,
I use my international variant S7(sm-g930f) on the ATT network, and they notified me that my phone will not work on their network in February 2022 because they are shutting down 3g in my area. They say my phone will not work on hd voice.
Two things I notice is that my phone does have 4g lte, and the ATT variant S7(SM-G930A) will still work.
Is it possible to make my phone still work on their network by installing ATT variant firmware?
Thanks
Hi guys,
Does your US unlocked version switch to HSPA (H) during calls? My friend with the Canadian version stays on LTE+ when making calls.
Thanks.
No. Also 256 snapdragon here on xfinity mobioe (Verizon)
Sounds like a carrier issue.
no, tmobile usa
I have an unlocked us version on tmobile, when I make a call it switches off 5g and goes to 2 or 3g and the call quality is horrible. Never had an issue with my s21 ultra. This thing has been extremely frustrating
No. Koodo, Canada.
Mine is a locked T-Mobile phone and I have no issues with calling.
Nope. US unlocked on Verizon. Stays on 5G.
