Problem with SM-G935FD on T-Mobile - Samsung Galaxy S7 Edge Questions and Answers

Good day, hope you are all enjoying the weekend.
I searched the forums for my problem but could not find any solution. Appreciate all the help you can assist me.
Here it goes:
I bought my phone unlocked from Saudi Arabia, a Samsung Galaxy S7 Edge Duos Model # SM-G935FD and it is working perfectly when I was there. The phone is updated and non rooted.
I moved back to the US 3 weeks ago and now using T-Mobile SIM only. SIM2 slot is empty.
The problem I am having sometimes when people call me, the call will either go directly to VoiceMail or rings 2-3 times then goes to VoiceMail.
Of course my phone shows no missed call notification nor does it ring, and after 1 hour I receive a notification that I have a new VoiceMail. Sometimes I receive it instantly and sometimes after 1 hour!
Mind you it seems to happen randomly and at first thought the reception in my area was bad, but it happens when I am away from home as well.
If I remember correctly it has happened to me a couple of times when I was in Saudi Arabia.
I have been reading lately here that using LTE/3G/2G Auto might be causing the problem.
Since this morning I am on 3G/2G/Auto setting and it seems to be receiving all calls with no problem.
Is it a problem with the phone or the network and what can I do to remedy it?
Thanks in advance!

There were reports showing issues about not receiving calls and forwarded directly into voicemail on dual-sim models but only on s9 s9+
I hqve the same s7 edge duos (bought in Dubai) and don't have the problem, probably is a ROM issue. Try BTU ROM for 935F the one I'm using now.
935F roms works on our 935FD's (also detects our dual SIM)

Thanks for your reply.
I'll install the BTU rom and hope it solves the problem

Well last night I installed a BTU rom and all is working.
But today just now the same problem happened.

Oh, really? What about call forwarding status?
On Phone app go to settings>more settings>call forwarding>voice call

Hey there sorry for my late reply.
I am currently using another phone in the meantime and planning to switch to Google Fi and buy a Pixel 2 XL.
I really think the problem is with the phone. My father has a T-Mobile SIM and an international LG V20 device and it is working perfectly.
I think the S7 Edge cannot properly connect to T-Mobile cell tower.
Also I am browsing the site: https://www.frequencycheck.com for more answers.

Did You manage to get a solution?
I am in the same boat. Bought phone from Dubai. Worked well for 6 months, till December 2017 but now it has the same problem as you faced.

Well not really a solution but here what I did:
I switched to Mint SIM and bought a Pixel 2 XL, which is working perfectly.
I gave my S7 Edge to my mother and she is using H2O Wireless SIM. So far it is working fine.
Hope this helps.

Hi there, I currently have the same phone and I too was experiencing connectivity issues when I first received it. I basically flashed it with a T-Mobile compatible ROM and changed the CSC to "TMB". This solution will have your phone running on a ported stock version of Android 7.0 (Nougat):
T-Mobile compatible ROM:
https://forum.xda-developers.com/s7-edge/development/rom-nougat-7-dplt-wifi-calling-volte-t3540723
CSC Selection Utility
V2.5.0 Android 7.0 Nougat
https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957
Select the CSC as "TMB"
I hope this helps!

I have the same issue, Samsung S7 edge from United Arab Emirates not receiving phone calls with T-mobile

Galaxy Note UK T-Mobile SMS issue - help

Hi UK Note users with T-mobile,
I don't know whether you also have the same problem: the note can receive SMS but cannot send SMS when it is in T-mobile orange signal, I wil have to manually change it back to t-mobile before SMS can be sent. Could please somebody offer a solution for this isssue/bug? Thanks in advance.
Mine has been fine on several stock roms. My phone came sim free. Is yours locked and are you using stock radio etc?

I have a similar problem. SMS says its sent but there is a spinning circle next to the message. The recipient gets some messages but others turn up later. Having read the T-Mobile help pages, I think you have to turn on data roaming. This is what I am going to turn today. But remember to turn it off if you go abroad.

Thanks for your reply. The phone is originally from O2 monthly tariff (unlocked). I simply use my t-mobile SIM card. The current Android version is 2.3.6, firmware version is 2.6.35.7-N7000xxkka, it is rooted. I am using handcent SMS app but the stock SMS app has the same problem. The data roaming is ON already.
Thanks for your reply, it is with official rom, rooted. Problem still exist.
Still doing the same thing, says sent but icon spinning when connected to T-Mobile Orange. It re sends later once its back on the T-Mobile only signal. so the person gets 2 sms messages :-(
Don't want to step too far out of my knowledge here but not had a problem at all on the sim free version, but worth installing the Carphone Warehouse rom from development?

No problems here.
This will sound stupid but try outting in another network sim. Booting up and installing the seyting from that network. Then outting your tmob sim back in and reinstalling the settings.
Works to solve quite a few probs on samsung ohones

I'm on T-Mobile here and not noticed any issues as it switches between it and Orange. I use Go SMS, everything works fine for me, but round here the T-Mobile signal is generally pretty good.

Me too I'm on T-Mobile and mostly use T-Mobile-Orange Signal as we have orange transmitters in place at work.
Never had an issue at all..
I too use Go SMS though...
Try that maybe.
Have you tried to re-set your SMSC? (SMS Message Center)
Couldn't find anymore the thread on XDA explaining it, but found this link : http://blog.empirion.co.uk/android/setting-the-smsc-sms-message-centre-in-android-ics/
Give it a try
Have you tried t-mobile page for sending settings to your phone?
http://support.t-mobile.co.uk/help-and-support/index?page=home&cat=SOFTWAREDOWNLOADS
Worked for me on another phone where i needed internet settings.
On the note i have used many ICS roms recently and never had issue with sending sms.
I think mine is fixed, following the advice above, I swapped out my sim for a Vodafone one, then after it booted, switched off and put my T-Mobile sim back in, now sending once only.
Solved!

Its Smspopup causing the problem for me. Disabled and all is well.
Mine is an O2 contract Note that came unlocked and unbranded. I'm almost constantly on T-Mobile-Orange (much to my annoyance) but I never have any issues sending SMS. I currently use Chomp SMS but I've also used stock and GoSMS with the same success. Is your SIM card particularly old? That's the only thing I can think might be the problem unless there's some weird fault with your phone but it seems unlikely. The only other thing is that perhaps there's a fact with the Orange transmitter in your area. Does the problem occur elsewhere?

It is possible that the problem is caused by the 'old sim card'. The sim card is originally a 3 UK PAYG one and I just port the number. I shall discuss this issue with T-mobile and to see if they can issue me a new SIM card.

Okay 3 samsung s4's the original one , the refurb one they sent and the new one they sent out all have the same issue when you dial out it sits there saying dialing nothing happens.. if you take her sim out of the s4 and put in the HTC One it works no problem, put the sim in the LG OGP and it works just fine, put the sim in the LG Nexus 4 and works just fine also put her sim in nokia 920 and it worked just fine so my question is has anyone else seen these issues with the GS4 no dialing out, receiving text messages hours later, and constant phone not on registered network. And she had the s3 before this and had no problem and the store put 2 new sims in it.

Ok just checking.. I haven't seen anybody else with similar issues.. I would go to the at&t store and talk to the manager or call customer service and talk to a supervisor.. Tell them you want an exchange done in store so that you can test it out before leaving... Or you want a different device.. Whichever you would prefer but no matter what I would do it in store so you know it works when you leave

Vodafone UK, unbranded S7E, any way to get WiFi calling at all?

[SOLVED]
Please see this comment for how I weirdly got WiFi Calling.
Hi guys, signal in my house is horrific - I've been trying to get WiFi calling for ages, and loved it when I was with EE.
I'm now on Voda and don't have it.
From what I've seen, it doesn't appear to be possible with an unbranded phone (why Voda!?) through any normal/configuration means.
I have the option to turn it on under settings -> applications -> phone -> wifi calling, and I've sent 'CALLING' to 97888, but only get the confirmation of the text, and nothing to confirm it's been set up. However, I don't get the little icon to signify that I'm using wifi calling.
Is there any way I can get wifi calling?
Does it require flashing?
If I'm going to have to root/flash anyway to get this feature, is there a way to do it one of the nice custom ROMs I see on this forum, but retain the vodafone branding?
Thanks all.
Easiest way is to flash a Vodafone firmware. Had to do the same to get EE WI-FI calling working. There is an option in unbranded firmware but activating it does nothing
Sent from my SM-G935F using XDA-Developers mobile app
Just flash latest Vodafone firmware that way you will not trip knox and you should get wifi calling
I suggest you check with your provider, if the unbranded phone was not bought from them.
Wifi calling may not be allowed because the imei is not registered to a vodafone branded phone.
They may have blocked the wifi calling feature.
Hey,
I've got the Google Pixel phone which I bought from Carphone Warehouse. Vodafone have told me that WiFi calling should work with it without any special firmware. I've tried using my SIM card in a friend's Samsung Galaxy S7 Edge which he bought from Carphone Warehouse and it worked! I too didn't get a text message from Vodafone when I texted 'CALLING', but WiFi calling is now active on the SIM card, albeit not the phone. Have been in discussion with Google who have escalated my problem to their technical people. Hope it can be resolved very quickly, otherwise returning the Pixel, which I don't want to do.
Thanks very much for the replies guys - I have something to report back to you all too. Unsure HOW this happened, but it happened... I somehow got WiFi Calling.
I'm scared to try do anything else like switch off my phone, because I don't want to lose my new WiFi Calling.
Here's what happened:
I have an EE iPhone 5s, locked to carrier. I'd recently requested an unlock from EE. It had been switched off, and was recently hard factory reset. Unsure of iOS version.
I put my Vodafone SIM in the iPhone today to see if it had been unlocked... it hadn't. SIM was in there for roughly 1 minute.
I put the SIM back into my S7E... started getting the usual texts from Vodafone about changing SIM, blah blah.
Somehow, I now have WiFi Calling on my unbranded S7E on Vodafone!
At no point did I switch off my S7E during SIM changing.
*NOTE* I'm not sure if something has changed recently, but I definitely did NOT see the WiFi Calling symbol before I did this:
I have no idea why/how and I can only speculate.
But... there we are!
Not sure if anyone else can try/vouch for this, as I realise it's a VERY particular set of circumstances, but I hope this helps someone!
Please do respond to me if you try this out and get it working... it'd be interesting to see if it works for others, and maybe figure out why it works.
Cheers!

Problems getting Wifi Calling with EE firmware on S8+

Hi everyone, hope I'm ok posting this here but I really am at my wits end!
I bought an S8+ from Amazon.IT (I live in the UK) as my previous N5 didn't support WIFI calling. I've downloaded the latest (H3) EE UK firmware for the phone and have flashed all 4 items yet I still don't see WiFi calling. I DO get the option in the dialler but no icons at the top and no WiFi calling when I enable it. EE just say they can't help as the handset wasn't purchased from them as that it's definitely not a problem their end. Before flashing I still didn't have WiFi calling either.
Oh and I've tried resetting the cache and doing a fully factory reset on the phone but still nothing.
Anyone got any ideas? Right now I feel I've just bought a very expensive paperweight!
Cheers

Vky-l29 with 8.0.0.386 (c432)... Canada?

I have been trying to figure out how to change to Canadian region. It was suggested to me that because I have the European rom on the phone, I cannot get wifi calling and volte calling. I cannot seem to find such a rom for the p10 plus dual sim.
Any suggestions?... Thanks in advance.
I was hoping when I received the update to PIE I would get VoLTE and wifi calling but still nope. I do not have the toggles to turn on for either function. My phone is not rooted.
I am on Freedom Mobile (and my wife's Samsung S8 works with it) but the techs say they cannot get it to work. I tried contacting Huawei and they said it is a carrier issue and the phone itself should work once the carrier sends the software. Freedom does not understand what that means.
Does anyone have VoLTE and/or wifi calling working on the VKY-29 p10 Plus? If so, how?

I know 2 people with Roger's who do have the toggles ... I am going to try and borrow my colleague's SIM and see if it will update my phone. If it does, hopefully when I put in my SIM after, it will still have the toggles visible.
I have it. I'm in south Africa. Working on multiple carriers here.

Well I borrowed a SIM but no luck. I had them call into to Roger's but was told since the phone was not purchased at Roger's store they would not send the carrier.
So far, Freedom will not send the patch. Roger's will not send the patch. It seems Bell (as posted above) doesn't support. I will have to try another carrier. I will post if I find one that will.
