Hello everyone.
I'm new here and this is my newest phone purchase after weeks and weeks of research I decided to purchase this phone. However I'm having one big problem. I cannot receive phone calls using the phone. However I can send text messages which is strange and when I try to talk to someone it switches to 2G for no real reason too.
It's fully updated and completely stock in fact just purchased three days ago. I'm wondering what I could do so I can get this thing working again. I have 30 days to return this thing, and I rather not because its a rather good phone and I like it a lot but if I can't get it to receive phone calls then I have to return it.
please help anyone.

Try installing the t-mobile visual voicemail app, there maybe settings in there you can adjust, only if your U.S though.

Alright I'll try and install the T-mobile visual voicemail app and see what is good
APN settings yes? I have tried that and tried inputting a manual one and even the ones on there which has three types of T-mobile settings
I'm not an expert on this but I have been looking for info on this for a while before I buy an A2 Lite to use on T-Mobile and I believe this post by a T-Mobile MVNO customer service rep may answer your question
The TLDR is that T-Mobile strictly uses band 12 for all VoLTE calls and if the phone doesn't support band 12/VoLTE T-Mobile forces it to use 2G for calls and texts. In some areas where the spectrum has been refarmed and there are a lot of 2G users your incoming call will time out before the tower finishes searching for you on VoLTE and ultimately tries to connect you to 2G, resulting in your phone not actually ringing.
This would also explain why there are no issues with texts, since they don't time out like an incoming call. Apparently there is no solution to this if you live in certain areas and use T-Mobile, and it will continue to get worse as spectrum is refarmed.
Sorry for the delay -- I'm technically off today. I saw you question and just had to pop in and answer, because I have a complete answer for you. Your issue is band compatibility, specifically the lack of Band 12. Let me explain:
For years and years, T-Mobile sent all their calls over the legacy 2G network on 1900MHz. Every call and text message went over this frequency, and all T-Mobile phones still support it for backwards compatibility.
Then, T-Mobile launched Voice over LTE, or VoLTE. But, they made the stipulation that VoLTE would only ever work on LTE Band 12. That means that any phone that didn't specifically have Band 12 LTE would still have to use the 2G 1900MHz frequency to send all calls and text messages. Any phone that did support Band 12 could use VoLTE and would send all their calls and texts through that VoLTE Band 12 connection.
That's not really a problem for most people, as T-Mobile's 2G network is still live in all their markets. These phones will connect to the LTE network for all data, but all their calls and texts go over that 2G connection.
Enter the problem: Spectrum crunch. Spectrum in the US is a limited resource. That's why the auctions always for it always go for millions of dollars for tiny portions. T-Mobile (and by extension, all its MVNOs, as we have no power over how they build their network) wants to make LTE the new standard, and push into 5G. In order to do that, they need to launch LTE in more places, and feed more devices than ever. They only have so much spectrum, so they reallocate what they already have to the new technology.
This is already happening with 3G. 2G is, again, just being kept around for backwards compatibility. They take the sectors that broadcast 3G (and 2G) and make them smaller and smaller, so the rest of the room can be used for LTE to service more devices faster. It makes business sense.
The process is called "re-farming" spectrum, and a quick Google search quickly becomes a rabbit hole as you find other people in your circumstance. They put the disused services on tiny little slivers of spectrum, some as small as 5MHz, which without getting too technical, is tiny.
If you happen to be unlucky enough live in an area where they're re-farming 2G spectrum to LTE, and your phone doesn't support VoLTE on Band 12, you're effectively fighting all the other T-Mobile (really any carrier, but for arguments' sake) customers whose devices also need to connect to that 2G network
Add enough people, and you get the problem you're having. A call comes into the network, and the towers go to work trying to find you. First, they try VoLTE, and don't find you there. Then they try the old 2G network, but there's like 200 other people in your area that are connected to that one tower, so it has to fight through them all to find your SIM card number and connect the call and-- right before it connects, the call times out of rings and your caller is sent to Voicemail.
You never get a missed call alert, your caller isn't alerted that your phone didn't ring, and because your phone didn't get a confirmation, you probably won't get a voicemail notification.
This doesn't affect the phone's ability to connect to the 3G network or 4G LTE Bands 2 and 4, which lots of phones support. But calls and texts don't travel over those networks. You'll still have an active, working data connection if this is what's happening to you, which is why it's hard to diagnose not just for Ting reps, but our customers and other MVNOs, as well as T-Mobile itself.
This problem isn't going to go away, and it's only going to get worse as re-farming 2G goes nationwide. It's not Ting-specific. Any T-Mobile device will have this problem if there are enough 2G-talk-and-text users in your area.
The phone in question, the Blu Vivo 5, supports Band 2 and Band 4 for LTE, but doesn't support Band 12, and thus doesn't support VoLTE. This is exactly what's happening to you.
This is exactly how it happened to my S/O. She had a Motorola Droid Mini on Ting GSM that worked great for years, on two distinct T-Mobile-powered networks. Then, T-Mobile re-farmed enough 2G in our area that she started missing calls, texts wouldn't arrive and she wouldn't get voicemails. The key identifier that this was her problem was that placing a call would take something like 10-15 seconds to connect. Typically, this should be instant.
There was nothing wrong with the phone at all -- it was working as designed. The second I got her into a Band 12 VoLTE phone, the problems disappeared completely. Nothing else changed.
The only solution is a new (or new-to-you) phone that supports Band 12 and VoLTE. No number of hard resets, network resets or new SIM cards will fix this problem. You'll have this problem on any network that uses T-Mobile as their backbone, as long as the phone you're using doesn't support Band 12 LTE and VoLTE.

Thanks fam, I'll return it and get another phone I appreciate the information brother.
Hi all,
I have in my hands an unopened G960F/DS. I was considering this phone to replace an old model, it's long due. I thought I did my homework and was able to determine this phone worked on Verizon in the US, but a serious note on the box and further research suggests I may have been wrong. Although it would be nice to have new hardware, I am replacing the old one almost entirely out of a desire to flash a custom ROM on it. I was under the impression the lack of CDMA support wasn't a big issue given that Verizon (and everyone else) is phasing out CDMA and the phone still had LTE. Thus my choice of the F/DS. I am informed that opening the box and returning the phone will incur a charge, while keeping the box sealed and returning it will not. I am trying to decide to continue forward and test on Verizon's network here in the US or just return the thing, the choice lies in compatibility with this network. So now I get to play a guessing game.
I find myself in 4G LTE areas most of the time. I want to use data and make voice calls.
This 2-post thread suggests not much can be done:
https://forum.xda-developers.com/galaxy-s9/help/sm-g960f-verizon-network-t3856443
This guy demonstrating slower speeds, which I'm not too concerned about, but also HSPA+ in an area he usually gets LTE. In the video description he says after applying a software update it works 'fine':
https://www.youtube.com/watch?v=pkNXCK2iVO8
This site lists some band compatibility but doesn't say anything about not being able to use it with Verizon:
https://apn.gishan.net/en/apn/verizon/samsung-galaxy-s9
This site also lists band compatibility but warns about Verizon's strict device policy:
https://www.frequencycheck.com/carr...e-samsung-star/verizon-wireless-united-states
Is there any hope to use an unlocked S9 on Verizon in the US? I see this going one of several ways: 1) Everyone works out and I can make calls and use data and there are no issues and rainbows and unicorns 2) Data in certain places, no voice because something something "VoLTE" 3) Absolutely no data/voice whatsoever 4) I switch carriers I return this piece of junk and buy a phone that works. (might coincide with 2/3)
If I end up with (4), how can I avoid this issue in the future? I spent some considerable time deciding on this model, which has the features I want and an unlockable bootloader. Will the S10 have this issue? What about the Note 9? I apologize for the noobposting, and if I missed a thread that answered this question. Thanks for any help you can provide, I sincerely appreciate it.
Edit: This thread asks a similar question but isn't specific and neither are the answers:
https://us.community.samsung.com/t5/Galaxy-S9/Unlocked-galaxy-S9-on-Verizon/td-p/277493
I have been using a G965f/ds on Verizon Wireless.
VoLTE, vowifi, text, and data work after rooting.
Having done a speed test with a U device and on the g965f/ds, the speed I can receive seems equal.
I haven't had issues with making LTE calls in my area.

Thanks for the feedback. Are you based in the US? How did you activate the phone? I found instructions on LTE activation here:
www . verizonwireless . com/businessportals/support/how_to_use/activate_4g_lte.html
And an IMEI checker, which fails when I enter what I find on the box my phone is in:
www . verizonwireless . com/od/prepaid/bring-your-own-device/#/checkDevice
Edit: It also looks like they have a second page that checks IMEI (this also fails for me). Can you tell me what either of these pages say when you enter your IMEI?
www . verizonwireless . com/onedp/byod#/
I reside in the US.
The imei of my g965d/fs failed when inputted in to their system;however, the SIM is all that's needed for Verizon wireless to work on it. Initially, though, you might need to insert the SIM card into another imei Verizon wireless compatible device only to allow the system to have that imei in the system for your number. Since, you already have vzw, I'm assuming you already are activated on it with a device, so moving sims is the next step.
Thanks for your input. Anyone else have experience with this device on Verizon's network?
I could have written this exact post.

I am trying to do the same thing with the same model Note 9, SM-N960F/DS. I was told by Verizon Level 2 tech rep that simply installing an activated SIM would make the phone work, obviously 4gLTE only since there are no CDMA bands. He checked the 4 bands Verizon uses for their 4gLTE and the F/DS model has all 4 of them.
I am in the same boat as you though. IF I try it and it doesn't work I have to return and lose $125 or switch to GSM network (AT&T or TMO) I am also trying to decide whether to take the gamble. This Level 2 Tech guy didn't mention anything about having to root the phone.
I would also like to know about the advisability of attempting this. I thought I read somewhere that this phone won't have any warranty in US anyway but I am not 100% sure about that. Sellers seem to want to gloss over that issue.
I'm very very interested in this
to put this to bed, you cant use any F galaxy phone on verizon and get full usage. vzw is a CDMA based carrier whereby voice is transmitted primarily via CDMA and data over GSM (which includes voLTE, obviously). The F model do not have CDMA radios in them. You CAN get data to work and therefore voLTE as long as you can flash the vzw CSC to get the phone to install the voLTE app. Long story short, dont try it. Its a fruitless endeavor. I mean, do what you want, i guess, but dont expect for the F to work well, or at all on vzw. There is nothing anybody on xda or anywhere can do to alleviate that.
I had straight talk using Verizon towers on note 8, my note 8 broke, I missed flashing custom ROMs, I bought a note 9 n960f, read online it would work too. I inserted sim. Did not get data or calls. Flashed custom ROMs found a lineage is rom that worked with data for like 2 min then quit. I kept Singapore rom csc stock radios I guess from Singapore, guy on here said he flashed Singapore stock Odin flash and ended up making his work but didn't work with my straight talk Verizon sim. My buddy came over and he uses visible network on Verizon towers we popped in his sim and it worked flawlessly on stock Singapore csc/flashed custom rom from xda. I switched, it's cheaper, it works and first month was 5$ no fee to transfer my number over. Visible is great, join a group and it's 25$ a month.
we have 3 Note 10+ my son ordered his the day of the preorder release. he has the 256 version and my wife and i got the 512 version.
Upon my wife and I getting the phones we replaced the sim chips with new ones from AT&T instead of removing the ones in our Pixel 3xl. I noticed that AT&T Visual voice mail wasn't there but after loging into our voice mail account it downloaded a different visual voice mail program.
however we are having signal problems, I noticed that we didn't Get Voice over WIFI, Advanced Messaging, Volte etc. I called into support 611 and explained and they said that they would re-register our phones to turn them off for a few min and back on and should be ok.
That didn't' accomplish anything. I talked with an engineer that I know that works for AT&T and he said that my son's phone is provisioned for VOLTE with torch i think but not in the account screen. My wife and my devices are not provisioned for VOLTE HOWEVER NONE of our phones are connecting for voice or data to 4G LTE only 3G. He didn't know why but would check further.
after complaining to OOP with Samsung and being within the return window they said that we could order from them the branded AT&T phones and return our unlocked phones.
I realize that we will get stuck with the bloatware, but if we are getting 4G LTE VOLTE etc. maybe that is what should be done.
If we do that can we still get them unlocked and what do we loose by doing this? I appreciate the work everyone is doing here and I think hopefully I can get an honest answer vs everyone pointing the finger at everyone else.
My big concerns are:
If I keep these what do we loose?
How bad is the bloat ware?
If we change to T Mobile or others later can we, or if we travel, get AT&T to unlock the phones
If I keep these phones and flash the AT&T files will we:
Then get access to the programs and services we don't have now?
Get over the air updates as they are released?
I would highly appreciate any advice
Thank you for everyone's help in advance
I was getting horrible battery usage on my At&t branded Note 10+. What I did was flash the U1 unlocked firmware, set things up, made a few calls, sent a few text so things provisioned to At&t. I then flashed At&t csc with odin and this gave me 4GLte..wifi calling..video calling..advanced messaging..and volte

I had the same issue - thankfully, I was able to test a friend's SIM card from AT&T and his worked! I saw an obscure reference (see below) to it being an issue with older SIM cards. I'm heading to AT&T store to replace mine tonight.

It's HD1907 T-MOBILE. What I need is HD1905. He sent me the wrong one.
I only realized a few hours ago I had no mobile data. I had got calls and texts to work this morning.
After spending 45 minutes on the phone with AT&T they concluded my phone is not recognized as LTE compatible. WTF? It's not even connecting to 3g.lb
I've been buying unlocked phones for years. My last phone was OP5T. I've never experienced anything like this.
I'll probably take it to the corporate store tomorrow but doubt it'll help. Has anyone had problems with AT&T and this phone?
I'm just putting it out there, hoping somebody has an idea...
AT&T worked for me, excellent data speeds, and great signal. But at times it would go from 4 bars to absolutely no signal or data, and lots of dropped calls. After that I went to Verizon, not as good of signal, slower data, but no dropped phone calls or mysterious total loss of signal in an area where it should have been 4 bars.

I'll bet if you look in the settings your model is HD1905 or the global model, not sure the number.
Actually if you could take a look for me and post back here that'd be good. It most likely won't make a difference but I'm curious.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

I'm just confused as to how he would be able to add it to the list of approved devices.
Anyway it's BS. If the carrier supports the phone, and the phone is capable of VOLT!/WIFI CALLING, it should work.

Yes Verizon. I have heard hear many times on this site, that phones are blocked from wifi calling by the IMEI, I or they could be wrong.
Vowifi works on the unlocked Pixel, but are they going to butt heads with Google? Volte works fine, I got a network extender, and I can use google voice to make calls over wifi if I really need to.
If vowifi is a must, get an approved phone, that is all you can do.

I worked at AT&T until a few months ago. I can tell you confidently that their tech support is a bunch of dummies. Employees have their own tech support line to call and that one is just as bad. They would routinely tell customers they needed to go to a store to have something done. Then they'd get to the store to find out we literally cannot do that at the store. Stuff like that was super common. One of them even bet me $1,000 that iPhones DON'T reboot when they update, which we all know is all the way wrong.
I halfway think support tells people that stuff on purpose to try to get them to buy something from AT&T. God, I could rant about that place for hours lol

Maybe you can answer this for me. Just because a T-MOBILE locked phone is able to make calls and texts on AT&T, does that automatically mean it should be able to connect to mobile data?
I was able to get it to make calls after a refresh signal was sent out, but it could not connect to mobile data . My sim is fine. I even popped it my son's Pixel 3a and LTE started immediately.
The seller is saying the fact that it was able to make calls means it is able to connect to mobile data. And I should take it to AT&T before returning it. I don't think he's scamming. He says he has the same phone on AT&T. And he's sold Hundreds of them. That kinda checks out based on reviews and some of those people do report it works with AT&T.
These phones are hd1907 T-Mobile but supposedly OnePlus unlocks them before sending them out to some sellers. I sort of believe the guy but is it true? If it were locked to T-Mobile could I get it to make phone calls?
Obviously I'm not talking about a hack. Because I thought locked was locked. Is it possible for a locked T-Mobile phone to make calls on the AT&T network?
Also I got AT&T to make it work but once I removed the sim/reinsert it, the thing displays weird behavior. Wifi goes in and out. It forgets the apn settings that were set prior.

I agree, ATT was the most horrible experience I ever had. Tracfone may have even had a better customer support.
Verizon CDMA service may be antiquated, but their customer service and tech support is 2nd to none.

It should have no trouble using data BUT you'll have to change the phone's APN settings to match your carrier before you can. You can google it and find them. It's not hard at all to change. Somewhere under the "network" settings.
Someone correct me if I'm wrong, but as I've understood it the phone will keep trying to access the previous carrier's data network, which is why you didn't have data. But as said above the APN settings should fix that.

If I told you the whole story, which started on Friday morning and in the end involved 7 AT&T employees, 6 on the phone and 1 in the store, it'd probably be removed because it's spam. Too long of a story.
But in the end it didn't get to connect to mobile data..at least not consistently. I took it to the store. The guy removed the Sim reset it, turned it off and boom! - LTE, calls and texts. His theory was it takes a little while for it to unlock and get set so when I tried it the other night it wasn't working.
I was happy because it literally took 5 minutes. I ran some errands and was out for like another 2 hours. Everything was working. Some point between the store and my driveway, the signal was gone. I never got it back. Of course I tried reset, remove Sim, reboot, change apn settings.
I called AT&T... the first woman didn't even know what CDMA and GSM was. I politely got her to transfer me to the guy who 'knows his stuff'. He got it to make calls again, but in the end concluded this device can't work on this network. I didn't wanna argue anymore. He had a BS answer for everything including 'If it doesn't work, why DID it work just a half hour ago?'
He said I could try getting a new sim. They have no idea. My son's sim won't work on this phone but pop it in my old phone and it works. And my sim works in his phone. It's not the sim. I know it.

I've been buying unlocked phones for years. My last phone was OP5T. I've never experienced anything like this.
I'll probably take it to the corporate store tomorrow but doubt it'll help. Has anyone had problems with AT&T and this phone?
I'm just putting it out there, hoping somebody has an idea...

I took it back to AT&T yesterday. There was someone in front of me so I sat down, removed the sim from my working phone, popped it in the op7t... instant lte, calls & texts. The same thing happened the day before I went to at&t. It worked perfectly well there in the store and even 2 towns away but not m my neighborhood which DOES connect to LTE, has for years on every phone we've had.
The tech (if you can really call him that) updated the sim. That got it done. I've had a working phone for 24 hours. BUT no LTE. It only connects to H+.
I haven't had time to call or go back to the store, but I'm hoping it's an easy fix. This has been the weirdest week I've ever had dealing with a phone. I've learned that AT&T doesn't know what they're doing. I still can't believe I needed to explain what GSM and CDMA was to one of the people on the call.
I'm gonna try a few things tonight after work.

Thanks for sharing, but I've never really needed to mess around with the settings as far as mobile data goes. It either works out of the box, or at most I'll need to put the apn in manually on some custom roms, but even that's rare.
How does the info you provided apply to my problem. I know the phone can connect to lte. It was connecting briefly on Monday afternoon and while I was at At&T yesterday, it connected before they updated the sim.
Is there something I can do with this? It's a sincere question. I'm not sure if I can apply it somehow. Thanks

I think his point was to show that the OP7T does in fact work on all AT&T bands. Normally you don't need to do anything with this if the SIM is provisioned correctly.
What are the chances that you are on the edge of the local AT&T LTE signal so it drops to H+ because that's a stronger connection? At the AT&T store the LTE signal is stronger so the phone is favoring that one. Some phones are more sensitive to signals than others (or more aggressive at switching to a stronger band).
Try using a program like "LTE Discovery" and see what bands you actually are connecting to. It can also let you know what is going on in your area with tower location.

I'll try that. Thanks.
That's what I said but the guy at the store said it's really not a stronger signal at the store. Plus I know I can get LTE at my house and in the store because all our other phones connect, even this one, briefly at the at&t store.
The seller have me a code to input into the dialer but I'm waiting for tomorrow to put it in. It's my day off. If something goes wrong it won't be a huge deal. I will look into what you sent at some point though.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

Your posts are bouncing between VoLTE & VoWiFi.
LTE bands and VoLTE work fine on Verizon's network.
Verizon allows VoWiFi on the OP 8's that they sell. They will not activate VoWiFi on the OP 7 series, the claim is that the phone did not go through their security testing. IIRC VZW doesn't allow VoWiFi on any outside phone.
Dear Experts,
The cell phone I've been using
here in the USA is a Motorola G7 Plus,
with the Lineage 17.1 OS.
Yesterday, March 2, 2022, I couldn't
make a phone call. Immediately, the
call would end, and a message displayed:
"Call ended".
The folks at the ATT store in the mall
immediately suggested that I get a new phone.
My question was, why was I not warned about this?
It's been planned for a while now.
T-Mobile, Verizon, AT&T, and Sprint 2G/3G/4G LTE network shutdown dates: the sunset!
T-Mobile, Verizon, AT&T, and Sprint 2G/3G/4G LTE network shutdown dates: the sunset!
When are the carriers retiring their legacy 2G/3G/4G LTE networks? Here are the dates...

However, ATT docs says that the G7 Plus will work.
Mysterious.

After swapping my SIM card with various
phones, turns out the issue is the Lineage OS.
Results:
...
Motorola G7 Plus, Lineage 17.1
- call ended
Motorola G7 Plus, Lineage 18.1
- call ended
Samsung Galaxy A32, out of the box Android
- calls work
Motorola G7, out of the box Android
- calls work

This is disappointing, as I like to use Lineage.
I've been looking at the Lineage compatible devices:
Devices | LineageOS Wiki
wiki.lineageos.org
Of the 165 phones there, many look to be a
number of years old, and would not be a
candidate to work with ATT 5G.
q1:
Is there a setting that I need to tweak to
make Lineage work with ATT 5G?
q2:
What current phones can be converted to Lineage, and
are now compatible with ATT 5G?
Is there a list/link?
Or does anyone speak from experience?
Thanks a lot
I found out that it wasn't necessarily my phone. Over the past 5 -7 days in my area and maybe everywhere, ATT was doing switching to eliminate all 3G. I had been warned last June that this was going to happen and even tho my phone was VoLTE and 4G, consumer cellular was adamant about making me get a new phone, so I bought their samsung A01for $100 just to shut them up. Consumer Cellular actually shut my service off, forcing my hand and that was when I was living down in Alto Texas. However, I didn't like their phone because it was all googled up and I went back to using my Moto G7 plus with LineageOS. It has been the phone I depend on and I like it best. When my phone stopped working a couple days ago, it was right after an update, so I assumed the update was the problem or my phone was haywire. Then, I found out thousands of people were having the same problem from https://downdetector.com/status/att/ and they do consumer cellular, too.
Now, the new minimum requirement is to be 4G LTE compliant.
After giving up on Moto G7 plus, I put my sim card into my old Galaxy S9+ and it worked. I made a phone call and talked for more than an hour. After I hung up, I tried to make another call and as soon as I dialed, I was returned the message, "call ended" and I couldn't get it working again. So I moved the sim card over to the phone that Consumer Cellular sold me last summer, the samsung A01 and no mojo. I messed around with it for an hour or so. Also, I forgot to mention that whenever I put the sim into a different phone, I would get a text message from Consumer Cellular letting me know that they have somehow configured my phone to work on their network and I have no idea how that works because when tried to show someone the messages they sent me, they were gone as if someone had deleted them and I had no idea that the sender of a text could delete the sent message on the recipient's phone, nor push a configuration. Long story short, nothing worked.
I stopped in at the local ATT store, today. The guy looked at my phone and changed 1 thing (my APN) and it started working. He changed it from Pure Talk USA (att.mvno) to ATT Nextgenphone (nxtgenphone). So now I can make phone calls and check my voice mail etc.... however, I am NOT able to use data from the tower. My wifi works, but I should be able to get data from the darn tower. no luck. I just wanted to let everyone know that I dont think it's my phone. I think it's consumer cellular and ATT or maybe just ATT because consumer cellular uses ATT towers.
