How to enable video calling on unlocked SM-N910A On T-Mobile network

I am using unlocked SM-N910A On T-Mobile network. I am trying to enable video calling on Phone app. I checked setting under Phone app but did not find anything.
I also noticed that when I go to Settings -> More Settings - I see first 'Network or Sim card error' popup with ok button and after that other options (i.e caller id, call forwarding,auto redial etc) are loaded on screen.
Any input will be great if this can be done or limitation.
APN is fast.t-mobile.com
Settings -> Connections- > Mobile networks - > Mobile Data -> "Enhanced 4G LTE services" is checked.

I'm on ATT using the same phone, and I don't think ATT supports video calling on their phones. I don't know for certain, but my last 4 phones were all ATT and none of them had native video calling. I always had to use apps like Tango. I could just be in the same boat as you and just don't know how to activate the feature or something.

To: spexwood,
Thank you for reply.
I also noticed there is no wifi calling option. there is also "sim card or Network error" while setting forward calling.
Based on following links,it seems it is a limitation

5.1.1 is the latest version, but the only way to OTA is to use an ATT sim card. You can Odin the files though.
I recommend updating just because 5.1.1 is much stabler, but I don't think it'll help you. I'm on 5.1.1 and as I said, I can't find any way to use video calling.

1) No wifi calling option
2) No Video call

I can't answer any of the last 3 questions, but can the first few.
OTA (Over The Air update) is not possible without having an ATT sim and being connected to the ATT network.
With a different sim, the phone will ALWAYS say that no update is available and that your phone is up to date when it isn't.
Kies will act similar as to not having an ATT sim. ATT doesn't upload their updates to Kies.
The only way for you to update would be:
1) borrow someone's ATT sim card and use it to connect to the ATT network
2) go to a Best Buy with a Samsung Experience area and ask them to update your phone. They'll do it for FREE and it doesn't matter where you got your phone. You do need to tell them that you're using the ATT phone on a different network. This will male sure they flash the correct firmware and not brick your phone.
3) Use the latest Odin file to update your phone yourself. This is basically what they'll do at Best Buy, except that you'll be solely responsible for the outcomes of your phone. The Odin files are posted in the ATT Note 4 General thread. Just do a search for Odin.

Need help unlocking LG G2 LS980 flashed to boost mobile.

Hey, I just need someone to point me to the right direction.
I bought my LG G2 off ebay last year, it came flashed to boost mobile. All I need to do is flash it back to sprint and unlock the GSM on the phone.
I just found this forum and don't know where to start in this process..
Im on 5.0.2
Software version LS980ZVI
Model # LS980
Thank you if you can help

this thread has everything you need
http://forum.xda-developers.com/sprint-g2/general/ls980-lollipop-update-root-sim-unlock-t3357837
After you install TWRP successfully but before you unlock the sim card, You can install the latest version ZVI that is already rooted
http://forum.xda-developers.com/sprint-g2/development/rom-ls980-stock-5-0-2-zvi-flashable-t3303163
for unlocking the SIM card I would use this procedure instead

Hey I did all the steps and got it unlocked but I cant to get my simple mobile sim card to work.
When I select the network mode global I have full bars, but when I try gsm/umts all my bars go away.
The phone is reading the sim card, but im not able to make calls/text. I Also get a authentication error when I try to update the prl/profile settings

did you do the twoclick procedure to unlock the sim card?
did you edit your apn? from the dialer, dial ##3282#
i am on freedompop so i changed my apn to freedompop.foggmobile.com. Simple mobile might require it to be mvno.att.net or something like that( i used that for airvoice).

tekweezle said:

Yep I did the two click method but on both of my sims my phone refuses to connect/ find networks. I get emergency calls only.
I used a freedompop sim too and changed my apn to freedompop.foggmobile.com. but it still wont connect to the network. When I go into the freedompop messenger app it says. I dont have any data.

that;s strange. It worked for me as soon as I added my APN. Does your phone see the APN for three.co.uk and 3hotspot when you have the freedompop SIM in there?
I don;t even use the Freedompop Messenger app. i just use the sim for data. i can test the functionality of the sim slot because I have a freedompop CDMA/Sprint sim card along with a GSM one.
there are a couple of other ways to unlock the sim slot-they're all based on the same way so don;t know if anything will be different. there is a simfree.exe and there is a thread by someone named summercat for a 1 click procedure. try one of those

im gonna tot back to zv8 and try this one more time or im just gonna go with ring plus or ting.
But thanks for all the help.

And you used ##3282# to add the new apn, correct?
I would go down to zve, then do the Ota update from sprint to zvg or zvh, then do the unlock and root and sim unlock. It's worked fine for me on zvh and zvi.

Yep, I enabled the lte/cdma, rebooted, then enabled gsm, rebooted and I got it to say freedompop on the lockscreen but after a couple of min. It went back to searching for networks.
im gonna try zve to zvg with the two click method

Good luck. The way you know it is supposed to be correctly installed is that your boot animation changes for the yellow sprint spark animation to some swirly wavy rainbow. The carrier image gets swapped to a gsm version.

I need help on samsung note 4 N910v

My friend brought an original refurbish Samsung N910v android version 5.01 which was working with GSM 2G if not 3G until when I tried to update to new version android v6.0.1. In the menu>setting>about when I checked first before anything it showed me N910 F v5.01 but in boot mode Odin it was N910v.The problem started when I just typed *#9090# the phone immediately started reboot loop. I have managed to unlock the boot loader and root the phone installed custom rom version 6.0.1 by Paul Pizz rom VRU2CPJ2.r-1 but still can not have 2G or 3G GSM network. Please help to revive the phone again whether it meant to go back to 5.0.1 that would work with gsm cause am full stack now.

Have you checked to ensure you have the APN information in place? I have a Galaxy Note 4 N910V now (just got it a few days ago) and when I put my T-Mobile SIM in it from the very first time I have to manually put in the APN data - on custom ROMs it's usually picked up and there automagically but not always so, my suggestion is that you check to make sure your APN information is currently there as it should be.
Settings - More - Cellular networks - Access Point Names - make sure the one you need to be using is selected and if it's not then you'll have to put that info in manually and save it.
As for the actual model number, take the battery out and see what the model number is on the sticker in the battery compartment area - if the sticker isn't there then it could be a device that someone has done some experimenting with because that info can be changed. The sticker should be there, of course, but sometimes people take 'em out when they're mucking around with stuff, who knows.

Initially the phone is from Verizon but was working on 2G ,3G GSM network with N910F firmware version 5.0.1.it was working on airtel network until when I wanted to update. May I have the Apn settings,please

The APN will be your network. Are trying to use Verizon? If so, you should have a spot to tic the VZWINTERNET. If not, then you have a sim card issue.

Is the sim from verizon? If you have a good account go to a corporate store and have them give you a new one. It's free.
Also, what are your APN settings and I will compare to mine. Everything works on mine.

the fone I have came from china ,am in Africa and remember I told you it was working woth N910f firmware version 5.0.1.All am asking is there anyway I could make this fone work again on Gsm network, cause all it says after re flash is the card is not from verizon

I now rooted this n910v android version 5.1.1 still no network, am in Africa where there is 2G&3G GSM network, how would I make this fone to work again with the gsm network now that I rooted. On the network bar I get a circle with a cross ,how to make this work

go in settings, connections and select network mode to global, should be fine

Verizon Note 8...T-Mobile sim - help

Hello all, new here and I just purchased a Note 8 from Verizon. The device is paid off fully and i wish to use my T-Mobile simcard in it but it does not seem to be picking up a signal. I did update the verizon software to the latest version when i had my verizon sim card inserted. Verizon customer service told me i need to reset to factor setting then my t-mobile sim should work but this has not helped.
How can i get my t-mobile sim to work? Any help appreciated as i am new to android phones!
Thanks

Hi there, you must flash the new N950U1 2BQK1 or N950U 2BQK2 stock firmware to have full access of T-MOBILE Network. It's the only way it will work, I have AT&T NOTE 8 working on Verizon network with zero problem.

It's a very easy process to flash the 4 US Carriers firmware, I have done it more than 50 times and I'm not a developer.

I would like to know where to get the firmware and with what do you flash it with? Is there a instructions thread or link.
It's been over 5 years since I have tinkered with a Samsung device.

Hi there. You'll need to have your Note 8 Bootloader version on level 2, meaning 2BQK2, 2BQJA or anything with 2 before the last 4 digits.
1) tmobile SIM card in device
2) Odin v3.12.7 make sure extract
3) 2BQK2 firmware extract all files
4) put all 4 set of firmware files in the right manner, bl,ap,cp and csc. Don't used home-csc only CSC.

First instructions is for if you want stock US CARRIER BLOATWARE FIRMWARE, second instructions is if you want SAMSUNG STOCK FIRMWARE. Follow steps and everything will be fine, happy flashing.

So wait, I have a Verizon Note 8 (currently using MetroPCS perfectly), but I wanted a stock Samsung ROM (without the Verizon crap on it), I can just flash the second set of files instead and done with it?

Yes

Can I use a gsm sim card and a verizon sim card at the same time on verizon branded phone? I see you have to flash the firmware above but am wondering if this would help me.

So much misinformation in this thread.
I don't even know where to start:
The OP was asking why his T-Monile SIM wouldn't work. It doesnt matter which firmware you're on, if the Note 8 is unlocked (the Verizon Note 8 IS unlocked), and it has a clean IMEI, and your SIM is already activated, then it will get 4G LTE. I know. I have a Verizon Note 8, and use it on Tmobile. I used it for over 24 hours with my T-Mo SIM but running thr Verizon firmware with no issues. Only reason I flashed T-Mobile firmware was to rid myself of Verizon bloat and to get wifi calling.
As far as bootloader, that has no effect on the SIM card working. The OP would need a v2 bootloader firmware if his current firmwarealso had the v2 bootload. It probably does, so thats a moot point, but the implication was the v2 bootloader was the only one that would make his SIM work.
I hope the OP got it all figured out.

plus the second SIM wouldn't have an IMEI assigned to it.
And I agree the OPs best bet is to flash thr T-Mobile firmware. But his issue was he wasnt getting a signal at all with his T-Mo SIM. Flashing firmware won't fix that. Source: I have a VZW Note 8 on T-Mo. Used it with the VZW firmware and a T-Mo SIM with no issues.

Hi all. For me I flash all firmware at clean wipe, never any issues. I have an unlock AT&T Note 8 unlock running the latest Verizon firmware with VZW SIM active. I also have a t-mobile S8+ unlock and running the latest U1 firmware and working with Verizon SIM active. I constantly switch my firmware between tmobile, verizon and at&t to see performance and what ever else feature added.

How did you get ATT N8 to work on VZW? I flashed my Tmo to VZW and i could never get speeds above 1mpbs. Even with unlocked firmware it did not get anywhere with VZW. I heard that its because the IMEI is not in VZWs database.

Hi there. My AT&T Note 8 works great on Verizon network, it's running the latest N950U1 Firmware 2BQL2, everything works great. It will work good on T-Mobile too, lately tmobile network giving trouble, sometimes less than 1 mbps on download. Since June 2017 I been having trouble with tmobile network in my area and around, so I switch to Verizon, couldn't bother the crappie service. My location I get 215 mbps on my note 8, IPhone 8 plus 147mbps download. I prefer Tmobile but it's not working good in area anymore.

@Mr. Orange 645
I currently have a Verizon Note 8 with a TMO SIM and I'm getting 4GLTE but a few problems. Most of the incoming calls forward to voicemail and all outgoing calls the data has to drop completely before the call can connect. Will doing the carrier switching updates listed in the link above as well as flashing T-Mobile firmware assist with this problem? The phone is on 2BQK2 currently.

Verizion note8 with tmobile sim card
This is what happened when I changed carriers from the original verizon note8, on verizon network, with verizon sim and the most recent verizon pie update, to a carriers sim, that is tmobile service. And what happens, I didn't even think was possible... I put the new carriers sim in, truconnect, booted and let the phone register the new sim and network. Checked for update.... the was one, let the phone download and update. And you know how Verizon's boot logo is... it wasn't anymore. Booted the tmobile boot logo and sounds, strange. I'm not super noob and the little bit of knowledge and experience that I do have with roms and updates across carriers usually require physically flashing the rom. Correct me if I'm mistaking. Continuing.... optimizing apps....., huh?! The update flashed the tmobile software, without effecting any personally installed apps. Though the update did remove all the verzion software/bloatware, without permissions, and installed tmobile apps. 2 that are meant for user usage. They are tmobiles device unlock and the tmobile app. Which I might add, do not function, I surmise, because in not on the actual main tmobile network, but a scabbed on. I have never seen or experienced anything of the short. Please tell me if this is normal.? I was a bit upset. I did not give any carrier the permission to delete or install any app on my phone. But maybe things have changed since I dabbled. And If they have, maybe this might help the people that have been using Odin to get tmobile version rom while originally being a verzion phone. I dont think it's normal. Please tell me if this has happened to you.

Did you set the APN information correctly?
Also are you using the N975U1 firmware or the standard AT&T firmware?
Are you using the BYOD sim card from straight talk?
What have you done over the phone with Straight Talk as far as troubleshooting? - this one can be important. If the phone isn't working with straight talk only it maybe a configuration (apn setting) or provisioning issue.
Are you sure the device is compatible with the area or region your in?
What provider/tower (Verizon, AT&T, etc.) does straight talk have you going through?
More information on what you have done to setup the phone for straight talk, troubleshooting steps you have taken, what information straight talk may have provided (etc. etc.) will help others be able to help you. Providing little or no details makes it rather hard to offer any help.

The apn won't let me put dun in the type I sim unlocked it with a puk code and got strighttalk byop I tried flashing the U1 firmware to it wouldn't take it so I did a Verizon firmware thinking that might help and same thing with the striaght talk it doesn't wanna work i put a Verizon sim in it and it works just like it did on ATT so I'm confused as to why the straight talk sim won't work they can't figure it out on their end either

I factory reset the phone reset network settings did just about everything I could with the phone besides it being funny about the apn cuz it says apn cannot be changed on this device if you put dun in the apn type i dunno the only thing I notice is when the Verizon sim card is in the phone the network mode is set to global whereas with the striaght talk its LTE/CDMA and it won't let you change it to global

Straight Talk uses different mobile providers to offer service different areas.. They utilize Verizon, AT&T, Sprint and T-Mobile (Sprint and T-Mobile have merged recently, but Sprint towers are still active).
I have seen posts across the internet that indicate you should be using the U1 firmware on the phone.. I would make sure your converting the phone to the U1 firmware properly.
If I recall correctly (this is how I did it previously) when flashing the U1 firmware make sure your doing it without the sim card installed and using the non home_csc file. Factory data reset the phone after you successfully flash the U1 firmware and then insert the sim card after setting the phone back up (so it can apply the new sim/network settings).
I would strongly suggest you do not restore a backup during initial setup when you do this. If you restore a backup it may restore previous network settings/configurations that were for what you had previously.
If flashing U1 firmware doesn't help (and since this this is a Straight Talk specific issue) then it's more then likely on the end of Straight Talk. I would call them and make sure that your sim card is the correct one for the cell towers they have you going through and the phone you have. Using an incompatible sim card (or one that is faulty) can cause issues like this. You can also have them send you another sim card to try.
Also contact them to make sure the service is properly provisioned and activated on your phone. Double check the APN with them, and see if they have an alternative one to try. It is also possible that a service outage maybe (or issue with Straight Talk internally) in your area, so I would call them to make sure that neither are not the case here.

The Global setting doesn't really matter in this case and your phone will be set to use the towers that Straight Talk has you going through.
The only thing that I can think of that would be a problem with network mode is if your sim card from straight talk is meant for a different provider then the towers they use in your area (i.e. sim card is for AT&T but the provider they have for the area is Sprint).

the straight Talk sim works in other phones no problem a s8 and a older note im thinking att has something in the software to block other apns i dunno i unlocked it with a PUK code and flashed verizon firmware on it thinking i could get passed it but the verizon sim works 100% and the att sim works 100% too but a straighttalk sim card (verizon) towers the phone tries it shows 4g and disappears and then it shows it has service but cant call it just says emergency calls only

I would not use older phones as a means to say the sim card is good. Besides that's irrelevant to what is going on with the Note 10+

Then this means one of two things... Either you didn't get the phone unlocked or else you did not convert to another carrier (or the U1 firmware XAA region) correctly.
If your using the unlocked firmware (U1 XAA region) then you should be able to edit the APN. If not then you should be able to create one.

That sounds like either the sim card isn't good, the phone was not activated/provisioned properly in there systems (call them and double check IMEI and model information), the phone is not compatible with the service they offer in your area (I suggest using the XAA region U1 firmware in this case) or else your phone is not fully unlocked.
I would also suggest google searching or else asking them for any updated or alternative APN's to try. It maybe very likely the one you have is not suitable for the phone/area... It wouldn't be the first time I have had an issue similar to this like this.
I am opt to believe the first 3 are the most likely scenarios since the phone works on Verzion with the sim card per your indication.

Yeah and the only reason I tried the older phone is to see if the sim card is activate with the number and the phone itself pulled the apn from network when I tried to flash to U1 the phone gave me a error but it took the Verizon firmware for the 975U but its still not working do you know of a good link for the firmware your talking about so I can try that

From personal experience I would advise in the future you don't do that. When you activate the phone you should activate the one you are using and definitely do not use an older phone to activate a newer phone. I have had many problems with this in the past as provisioning for an older phone didn't always work for my newer ones..

I waited for you to give more information on the issue, but you didn't. So I am sorry, but if you don't provide the details of what is going on it makes helping you very difficult. You didn't say what error you are getting, what the firmware version(s) are of what your trying to flash and what is currently on the phone.
Here's the last piece of help I can offer now.
I can tell you that the following can be found on the forum by searching:
Links and how to obtain the firmware - Multiple threads asking the same question exist here. Also Frija, SamFirm, SamMobile are just a few examples of what can be found referenced here.
Bootloader version(s) - what will happen when you try to downgrade and what will happen (along with a important thing) when you upgrade.
Websites to find firmware - SamMobile and some others have been mentioned.
Patched Odin - In case you need the latest version it has been mentioned here already.
I can also tell you that by using Google and searching for SM-975U1 XAA on Sammobile does in fact work.

Brother give me root file for note 10 plus SM-N975U android 10 version one Ul version 2.5 plz help me
