Hi everyone,
I've been a lurker of this site for a little while now, so thank you all for your productivity and guides (If I can get this to work, I will create a guide myself to share ) I recently purchased a Brand New Sprint Galaxy S5 (SM-G900P) with the hopes of unlocking it and using it on Straight Talk AT&T's network. I've made incredible progress so far, but I feel like I'm missing something. Up to this point I've spent countless hours online reading about this device and troubleshooting it.
Current Issue: Phone will not contact any GSM network. I have the sim card in and it just says no service. I know this is only on GSM networks because I disabled all CDMA bands using DFS. All AT&T bands are active and I believe the Galaxy S5 supports almost every band available. APN Settings are set correctly.
Things I have done / tried:
Using Cyanogenmod13 KLTE ROM, Cyanogenmod12.1 SPR ROM, Unofficial CM13 SPR ROM. Also, tried using a "stock?" 4.4.4 ROM that was a little glitchy, but worked nonetheless (tried using SSU.apk here, but afterwards it seemed to sim-lock my phone by giving "Invalid SIM"
Phone unlocked with IDoneApps (no more invalid sim) IDoneApps says its for International and Domestic.
I paid for a Network Access Code and registered the phone with Straight Talk and attempted to transfer the service over (not sure if this is necessary as I am using a GSM SIM, which still works fine in my other phone, perfect service)
Also, on the stock ROM it keeps trying to "Activate the device" and won't be able to. Sometimes the phone goes into roaming and when I call it sends me to Verizon Wireless Customer Service (not sure why on this)
Phone will receive service fine when set to Automatic or CDMA LTE. If I attempt to call a phone I will get "Your account is not authorized to make calls to this phone number" with a mans voice.
-Do I need to do something with Sprint to go forward?
SOLVED IT:
Had to enable the "GCF Setting" on the phone.
YouTube Video: "How to enbale GFC settings on any Samsung Galaxy " - This guide worked flawlessly.
Now all I need to do in order to have perfect service on this SM-G900P on AT&T is to enable the rest of the AT&T LTE Bands on it.
Hey, I know this is necro'ing but I hope you are still around.....
I'm in the same situation as this post right now...I have have a SM-G900P (Sprint Galaxy S5), now activated through Straight Talk, but my data doesn't work when using CM13. I was wondering more what you mean by your GCF settings and maybe some quick tips to get 4G/LTE while on CM (Preferably 13+). Stock Rom I get LTE just fine, but for some reason it gives me this *FUGLY* Creedo mvno app suite when I do a fresh restore of stock rom, and just the whole touchwhiz thing sucks in general. I'd much prefer CM or any other custom ROM that cuts out the BS but gives me data.

no worries about necro'ing a thread, im not sure why some folks get bent out of shape about it :/ anyways, what service provider are you using via straight talk? they use all of the major 4 (vzw, at&t, tmob and sprint)
the basic answer to your question is APN settings. did you ever have data working with str8 talk? if so, your gcf settings dont need to be fiddled with, if not, then you have some tinkering to do. not at all difficult really, just some button presses

Well, the only band that identifies when I actually have a working data connection (tops I get is 3G) says Sprint. So I think that's who they're routing me through. I'm not a total rookie when it comes to this, but I don't know how to change the radio bands outside of what apps like Radio Switcher do (which actually just gives me a short cut to quasi-service mode settings in CM).
I get the cell data to read LTE on stock, but it's gross touchwiz and it never seems to get GOOD signal, two bars of LTE was the most in Milwuakee suburbs, an area I'd assume would be swimming in 4G/LTE. I'd much rather use CM for the customization (or any more "purer" android ROMS). If I select CMDA auto PRL I get a solid 3G and all voice/text/data services work. But any other option that includes LTE drops my data entirely.
Edit: I just realized I repeated myself lol. I've made a few posts on various forums about this. Kind of forgotten what info I've provided where. Sorry for the redundancy.

i dont have any experience with the sprint flavor of straight talk service, but it should be on the same LTE bands as normal sprint. shouldnt have to monkey with anything tho. ill have to look more when i get home

Ok, I reread your op and it said that you're using at&t. Are you sim unlocked? If not, Mr @stifilz, do you think you could hook this guy up? He has a proven track record of unlocking S5s
Just a heads up I'm not OP, that's @aventurer. I just happened to find a very similar situation. Probably changes your train of thought but for what it's worth in my situation, the phone sim came from Sprint originally, and the Straight Talk people said they use that sim to connect to the LTE bands.
I have the international Exynos version of the S7 Edge and find cellular data stops working as soon as the phone gets on a voice call. The H+ symbol disappears, browsing stops working etc. At home it is not a problem as the phone is connected to Wifi and voice calls don't effect it, however, out and about, when on cellular data, internet is all lost.
Is it that the s7 doesn't allow simultaenous voice+Data?. I thought that was a problem with Verizon only, GSM (AT&T etc) versions don't have that problem?.
Riz
Have the same version and same issue. Heard that it's not possible to do voice and data together...Not sure how true it is
Got tmobile in the usa.
I have always been able to talk and use the net at the same time.
I do it all the time. Seems like no one knows how to looks stuff up so they always call me.
This worms for me on network 4g and wifi
I have the same problem on my g935f unlocked in europe, so I can confirm it's not an American company issue. I'm regularly using my phone as a hotspot for my ipad and whenever I get a phone call the H+ turns into G (2g) and Internet stops working.
Same here. It was like that since my first Galaxy S, it's a technical limitation of network protocols. At least in Europe.

Hang on lets rewind.
Are you in the UK.
The 4G network here in the UK is getting there, But its still got along way to come.
One of them is the ability to pass Calls via 4G.
The problem you have in the UK is 4G is data, While H+ etc is for GSM
The UK have not bought the ability to do both yet.
What should happen, is you will be kicked of the 4G network to take the call, Then be re-connected when you finish the call.
This is not device specific, Its Network Region Specific

In Italy too, and here happen the same thing in 2G too.

The S7E supports VoLTE. It's working on my device. But your carrier has to have it as a service.
Otherwise, you should still have 3G when making a call. If you don't, that doesn't seem right.
VoLTE
In order to make calls and use data at the same time mobile phone networks need to either ...
support VoLTE (Voice over LTE) on the network (Three in the UK is currently rolling this out).
or provide phones with dual antennas, one for voice and one for data (I believe some US networks do this).

No 3G, that's the way normal LTE does works. Just like 2G, because if you make a call under 2G, data connection will be turn off.

Basically it goes down to network support. I never have such problem with 3 UK but work Note 4 on Vodafone sometimes disables data when in call. Sometimes doesn't. Which leads me to believe that it's not just network but also particular towers.

Quick question about VoLTE: Has anyone tested if VoLTE works on the international version (SM-G935F) on AT&T?

I can only tell you that international version supports VoLTE, wherever it'll work on AT&T I don't know.

Each VoLTE network requires a special firmware. There is no AT&T firmware for international s7 edge (still, it might be custom roms supporting this).
I'm in Europe and with international s7 edge I can use voice and H+ data connection at the same time.
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.

Last phone I remembered being able to do this was the Note 3. Man I miss being able to use simultaneous data & voice.

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.
Hi guys,
For the past week or so any call that I receive are going straight to voicemail if I'm on LTE, but I have no problems when I'm on the GSM or WCDMA networks. I can make calls if I'm on LTE, but I think the phone drops to GSM or WCDMA in order to make the call.
Anyone else having this issue? Tmobile doesn't seem to think there's anything wrong as I can still use data when I'm on LTE and suggested factory reset. I've gotten a new sim card, reset network, factory reset...nothing so far! Very frustrating.
Edit:
After further investigation it looks like Tmobile did some network change and since this phone has no way to turn on voLTE that I can find, that's what's causing the issue. At least this is my assumption. I wonder if it's because I have the India variant of the phone?? I know Tmobile supports voLTE...
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.
