[Q] A stupid question: Is Samsung Tab a Phone?

Hi,
please allow me to ask this stupid question
according to the spec, it supports GSM network, does it mean I can insert my normal phone SIM card to it and make phone call?
I don't really want to have a data plan and simply just use my normal SIM card (if it's possible), and then use WIFI when access is possible (at home or in the office).
I am very curious if I can make phone call with it, so I don't have to use my current phone anymore
thanks

It would help if you did a bit of research into the product you intend on purchasing, as any review will tell you, the galaxy tab IS a phone.
If you have an EU model, it will support and allow phone calls.
CANADA ones I think you can make calls, but not out of the box.
US models do NOT support phone calls (Skype may work?)
ASIA Models seem to come without marketplace.

risp is partially right in regards to the USA models (T-mobile / AT&T) out of the box these 2 tabs are not able to make phone calls just use 3G, but if you flash a Euro Rom it will allow you to make phone calls, and you can get Edge (only using an AT&T or Simple Mobile Sim) on both AT&T and T-mobile tabs. Since you stated that you will use wifi either at home or office then you can choose either one of the two and just flash the Euro Rom and you will be set to make phone calls.

OK, I just called Rogers (a Canada carrier), it surprises me that the staff told me it cannot make phone calls. The GSM network only supports the data.
when you said flashing a different Rom can make phone calls, does it mean, the Canada or US model doesn't come with that software to make phone calls?
I haven't seen the device myself yet, is there a place I can insert a SIM card to it, and the device and recognize it? If yes, I am sure there is a way to use it.

It IS an do-it-all marvel
It is a one-unit that does-it-all (including voice calls) if you are anywhere but North America.
Here, the service providers are only offering units with the voice call capability locked out. Apparently want us to carry around two units, a tab and a phone like in the iWorld. Hum. Why? Could it be they want to get deeper in our pockets?
I have a regional service provider that that doesn't sell the Tab. But they promised me if I bought one from the UK (Clove Technology) and put their sim card from my old phone in it, they would give me both voice and data service. Very reasonable.
They don't "support" it but the local staff was so excited to get their hands on it and and play that they had me up and functioning in seconds.
I'm very pleased with it and don't see any reason why any provider that offers voice and data service on your current phone wouldn't be willing to let you pay them for the same service on an unlocked, fully functional Tab that you got from wherever.

T-Mobile is filtering voice because they don't want it to be looked at as a big smart phone. They want it to be a real iPad competitor so they are doing everything they can to make people believe it isn't just a big smart phone but rather something new. Of course we know it is just a big smart phone and naturally we want to makes calls on it but T-Mobile isn't having any of that.
Same with the other carriers in the US.

I was hoping I could get the galaxy tab to run 3g and also provide voice on ATT. It sounds like either you can get 3g data only, or edge data and voice if you are using an euro rom. Is it possible to get 3g and voice on Att by using a euro rom and jumping through some hoops?
Hoping I can just retire the iphone and switch over to the galaxy tab.
Thanks,
John

The AT&T TAB can do 3G and voice at the same time with the EURO firmware.

I found that thread by searching for the words AT&T and TAB. Stay away from the T-Mobile TAB if your service is through AT&T.

Sprint Nougat update can't surf while on call

Hello,
The nougat update was installed on my Sprint S7 edge the other night. Now I can't use the Internet while I'm on a call! I did calling and surfing with no problem before this update. I called sprint and they basically said that you can be on WiFi and call / surf no problem, which is true. But I am often away from WiFi and need to use internet while on call. I tried the different modes such as CDMA, LTE/CDMA, GSM/UMTS, AND Automatic but same problem.
Has anyone experienced this? Is there a setting or something to fix this?
Looks like I may have to go back to AT&T! ?
Thanks in advance

That is a limitation of Sprint, not Nougat. I switched from AT&T to Sprint last April and ran into the same issue immediately. While I plan to switch back to AT&T or Verizon, I've been using the hangouts dialer/google voice to make calls over LTE. This fixes the issue for me for the time being.

I've never been able to access data over cellular while on a call on my S7 Edge. Nougat or Marshmallow. Worked fine on older phones, but Sprint's Spark network doesn't allow it.

I came from T-Mobile who I truly despise so I decided to give sprint a shot. I've been on sprint for years now on and off and I have NEVER been able to use the internet while on a call. As others stated above, their POS network doesn't allow it. It was the limitations of a CDMA network, but couple years ago, Verizon upgraded their CDMA network and now they can browse and talk at the same time. Sprint is the ONLY network that doesn't allow it that's in the top 4. ATT, TMO, VZW. While sprint was racing to be the first carrier to allow 4G (which they were) other networks were prepping for LTE and setting up their infrastructure to surf blazing speeds and still talk and sprint is stuck in the stone age's. Rant over lol

Sprint actually did allow simultaneous voice and data for a while. It worked fine on my G3 (and still does, actually). But it doesn't work on any of the new phones that support their faster "Spark" network, or whatever they're calling it now.

what you said is 100% true but to add to the dialogue, the reason it doesn't work anymore is because manufacturers have reduced cell antennas down to 1
older devices used 2-3 antennas, so it was possible to use 1 antenna for internet on a LTE frequency while the other antenna was in use for voice calls.
VoIP is essentially a data stream so with 1 antenna that's the only workaround.

The last galaxy phone that did simultaneous voice and data (while not on wifi) was th GS3 . it had a radio in it call SVDO (simultaneous voice and data option)
no other galaxy phone since then can do both UNLESS your on wifi.

Regarding Sprint racing to be the first carrier with 4G (Wimax) while the others were prepping for LTE, Sprint wanted to also do LTE like the others but at that time LTE was nowhere near ready & they had to do something with the spectrum they were sitting on at that time or else they would've lost it.

Well that sucks. We should have that option it's freaking 2017 lol. It's hard to take them serious. I also keep hearing of a soft bank and TMO partnership they really do want to pair sprint with TMobile to compete against Verizon and ATT. If sprint did merge with TMO they could route calls through another frequency/band and have data sit on the LTE band.

Actually, a work-around that I've tried is using the Google Hangouts dialer. You can surf the web and be on the phone. Kinda sucks they eliminated the simultaneous talk and data.

I can attest that until the latest Nougat update (last week) I was able to be on a phone call while connecting to the internet and webex. I do this a lot due to being stuck in traffic and having to attend conference calls while driving.
My phone is a Galaxy S7 Edge. I also had this ability with my Note 3. Something fishy is going on here.
I'm really upset that this is happening all of a sudden, strangely right after the freaking software update. I want the feature back! Now every forum says that Sprint doesn't support it on these phone. BS! I am proof it did have the ability. They just took it away with stealthy maliciousness. Sprint needs to give us back the ability to use data and voice simultaneously!

I'm using s7 edge too. if anybody still can't use data while on call. try to turn off your power saving mode. don't turn off your power saving mode while you on call. off ur power saving mode before you call or answer someone. i update this reply while on call too.

I think nowaday most updates are all a big BS. just another ploy to take away all the neat features and give the phone companies more controls, limiting user ability, etc.... i.e. to save the phone companies bandwidth and data use..
My old samsung S4 can do everything after i completely rooted it. from hotspot to simult data and voice, also sim unlock... all done by me just reading xda
I want to upgrade to something newer with removable battery and microsd card in the form of a LG G5. and it's been a real PIA. first phone i got it has the latest firmwarez preventing any enabling of tethering or DIY sim unlock... Had to return it.... 2nd phone has earlier firmware so i can enable tethering. but has no way to use data and voice at same time.

International S8 (SM-950FD) On Verizon

Hey guys,
I bought the G950FD on eBay so that I could root and tweak it the way I always have with my previous phones. I use total wireless which is on Verizon towers and have gotten the phone to connect just like it should, text, receive/make calls, and use data. To do this, I used the Flashable CSC Collection here to switch the CSC to VZW and it worked for a while, but after restarting I started to get some problems that I can't sort out.
1. Calls do not work anymore - I can't make or receive them at all. Dialing a number just says "Dialing" with some zeros below it, and calling my number goes right to voicemail.​2. Data cuts out sometimes and shows no signal. Recently, I tried to search for carriers and reconnect to Verizon but now I can't get a connection at all without restoring a backup.​3. Other observations: Using a signal info app, it seems like I only see band 1 and it is usually very slow. CDMA obviously doesn't work, so maybe that's why I can't register on the network anymore, but why did it work when I first booted up? I can't change the APN settings after switching to VZW CSC and also can't see an option for VoLTE, but that must be working right? Only some ROMs seem to work with the VZW CSC and allow me to connect to the cell towers. Changing the network mode does not do anything and just reverts back to 2G, which doesn't make sense because 2G shouldn't be possible. None of the codes that can be entered into the dialer to run the activities have worked or helped at all. When connected to WiFi, the no signal bar shows 4G connectivity and the signal bars reappear but I am still not connected.​
So, what can I try and does anyone have knowledge to share about cell towers, SIMs, registering on the network, or anything else relevant to my situation? I am completely stumped and would love any input that you guys could give me and future 950FD owners who might have this issue.
I'm looking forward to hearing what you guys know,
Joe

Only verizon phones work on verizon, you can't use a non-verizon phone on its network even if its supports its frequencies. Lte on your s8 is compatible with verizon's but after it worked for a bit they disabled your imei from their network, nothing you can do about it.

Thanks for the reply! I do not think they have blocked my IMEI because I just restored a backup and everything works again. I believe it has something to do with the settings on my phone or possibly a bug with Android/changing the CSC because changing the network settings cause crashes, disconnects, and other weird behavior.

Lol don't give misinformation, they don't do this, in fact I'm pretty sure forcing all users to have phones obtained through Verizon would be completely illegal for a Telco to do. VZW doesn't even know what type of phone you have unless you register it and even if you do they don't care.

VoLTE on unlocked Note20 Ultra 5G Model N986U1

How can I activate VoLTE on the unlocked version? There is no menu selection for this and T-Mobile requires this by year end.

Hey as I understand it, that menu is no longer there, but the feature is there by default. No worries, you're good.

This is exactly what I have been trying to figure out the past 24 hours. I reached out to T-Mobile support and he confirmed the documentation they have from Samsung says that its enabled by default with no setting for it.
So I guess that means VoLTE is basically hard-coded into One UI 2.5. I'm not sure if there is any situation where it would be beneficial to turn off VoLTE, so I guess this makes sense. Especially since VoLTE will be required for a phone to function on T-Mobile starting on January 2021.

If you're in a weaker signal area a lot of times you can get to where your phone is trying to push VoLTE but it works like crap and you're better off disabling it. Those days will be gone soon enough though and I've curious where that puts us in terms of making a plain ol phone call in the future. I'm sure it will be fine in the city and on major freeways and so on but out in the sticks...?

My settings are there on an unlocked handset with a sprint sim

Great point! If its connected to a weak VoLTE signal that could be a problem unless the software is coded to switch it off automatically.

Hmm that's a little concerning. I am going to reach back out to T-Mobile and show them this. I don't have this option.
If VoLTE exists on your unlocked model, then I can't see a reason why it would not exist on my unlocked model for a different carrier. Especially since T-Mobile supports VoLTE on unlocked phones that have the hardware to support it.

Rumor has it they disabled the ability for you to choose it yourself; they don't want you doing anything but VoLTE being the reason. I do live in a low signal area and turn mine off most of the time as I'll usually have better call quality; it's people like me the restriction is probably meant to address.

I ran a volte checker on my unlocked N20Ultra and it's saying no VOLTE......

Sure enough... T-Mobile website for S20 verifies its not a setting that can be changed. So that means its a setting that doesn't even show. So that Likely applies the same thing for the Note 20 Ultra too.
Even with the unlocked model T-Mobile Likely pushes out the same network settings from the tower to the phone and that tells the phone what network settings to show as an option.
I'm guessing T-Mobile did this since every phone on their network is required to have VoLTE to work starting January 2021. Kind of a lame move.

? Using LG V20 H910 AT&T Model On T-Mobile After (2021) VoLTE Change

I posted this ? on reddit as well; however, this device is on its last legs so there's not much interest for it. I've gotten some good answers here and there on this website, but a dedicated thread to gather all the good info might be more helpful.
I still use my AT&T H910 as I don't really do much gaming on it. Calling, texting, and YouTube is what I mostly utilize it for. I just heard about the whole VoLTE requirement on specific devices after 2022 for AT&T, and 2021 for T-Mobile.
I spoke to AT&T, and they re-assured that the H910 was going to be one of the devices supported after 2022; however, I've been thinking about changing to T-Mobile (my family has a great plan with them, and I always switch back and forth between carriers based on who gives me the best deal) but I can't seem to get a straight answer from T-Mobile about whether my unlocked H910 will work with them after 2021; some didn't even know about the 2021 specifics of it.
I know AT&T will have to allow devices to be used on their network after 2022 even if they're VoLTE capable already. By the looks of it, T-Mobile won't go to that extreme; however, does anyone know exactly how VoLTE works? Specially in regards to using the AT&T H910 model on T-Mobile? Does my H910 has the required Bands to utilize VoLTE on T-Mobile? Or is it one of those things like "Wi-Fi Calling" where T-Mobile Wi-Fi calling only works with the LG V20 model from T-Mobile, and AT&T Wi-Fi calling only works with the LG V20 model from AT&T?

You need band 12 support which H910 has. Also a rom with IMS services working so no AOSP roms.
Volte works by using IMS processes in the rom to route phone calls over IP. No volte = no phone calls. But the device will still "work".
In theory the ATT software will work, unlock it and borrow someone else's sim. In theory a partial cross flash (just system, no modem/aboot/etc) could work if it doesn't.

I was recommended to use an app called Network Mode Universal on reddit for VoLTE testing purposes, and after inserting a T-Mobile SIM card that I borrowed on my unlocked H910 and using the application, the Voice Network Type tab says "LTE". Which is supposed to be a sign that VoLTE might be working on the H910 using a T-Mobile SIM, but that's all I know; just what people tell me.
Update:
The person who recommended that Network Mode Universal app forgot to mention that you have to actually make a call to know whether the phone supports VoLTE with the SIM card in use. When actually making a call, the Voice Network Type tab changes from "LTE" to "UMTS". Which means the H910 is not VoLTE capable on T-Mobile.

Could also be how his sim is set up. Volte has to be enabled there and in the phone. My suggestion would be to force LTE only on the device as well. Does it use VOLTE on his phone?
Also look at IMS registration in the phone and see if it's registered.

The person I borrowed the T-Mobile SIM from uses an iPhone on iOS 13. According to him, the option for turning on/off VoLTE from the settings is gone. He used to be able to turn it on and off at will; not anymore after iOS 13. It should be enabled by default on an iPhone though, I don't see why it would be off. It's almost a necessity on an iPhone I would think.
The LG V20 seems to be more limited in that sense, as on my previous Samsung phone I could enable 2G, 4G, LTE, etc, individually to force only one. I don't see any of those settings on my H910. I don't see any IMS info either.
Either way, I doubt T-Mobile would bother servicing my AT&T branded H910 phone in case IMS needed to be registered; in the case that it wasn't already. I've had really bad luck in the past dealing with T-Mobile on phones that are not T-Mobile branded.

IMS has a phone component and a sim component.
you can check status in the service menu of IMS on the H910. Hope it works on my Tmo phone, getting my sim upgraded

It should work if it's a T-Mobile phone. The H918 is 40% more expensive, so it would be great if the H910 worked with T-Mobile; however, it's not looking good.

Eh, kinda. I'm having trouble too. My IMS services aren't connecting. Going to try a few different roms. I'm through an MVNO so still trying to get them to understand ISIM vs USIM.

Gotcha, I hope it works. I was mentioning to @C D which has helped me understand a lot about VoLTE, that I'm starting to give in to the system of using whatever carrier my phone supports, as long as I can keep using my H910. The removable battery & IR blaster era has come to an end, and I don't think I need another phone right now other than the V20. I might even consider going back to the AT&T MVNO I was using before.

Latest result: oreo works but not nougat.
IMS never registers. Maybe I can fix it. At least now OK sim-wise. Unfortunately doing the sim swap broke tethering.

Hi guys, I am sorry for reviving the old thread.
I too owned H990DS Sea version on latest nougat. It has volte option but just couldn't switch on.
Please take a look at this thread on LG G8
https://forum.xda-developers.com/t/...ther-qualcomm-powered-lg-devices-too.4343655/
I tried on my H990DS using the above thread's method and it didn't work. I was informed that the mbn files are for LG G8. We need mbn files that are specific for LG V20. I have searched up and down and I couldn't find any.
So I hope that I have provided some insights and I hope any member/master/guru out there can help where to find the mbn file (collection of all international carriers mbn) and make volte works for H990DS.
