[SOLVED] APNs wont save & Straight Talk SIM not recognized

Trying to get my friends phone working on Straight Talk. So far, I found the APN settings but when I choose to add a new APN, enter the settings, and choose save... my APN list is still blank. Even after serveral reboots (I've read that sometimes that will make the new APN appear) it still does not show up.
I'm running CyanogenMod 10.0 with a fresh install after clearing all partitions and doing a factory reset. I've unlocked the phone with the app in the android market called 'Galaxy S Unlock'... I've tried everything I've read on the subject (and even had to re-flash from soft bricks)... What am I missing?
EDIT: I should note... after unlocking, my T-Mobile card worked without even editing APNs.
SOLVED: See my last post on this thread (http://forum.xda-developers.com/showpost.php?p=37664537&postcount=9)

First off does the phone work for phone calls and text messages on StraightTalk? Secondly when you find APN settings in the phone is there any list at all? Clearly the phone is unlocked since you got it to work on T-Mobile so it's not that.
Also I'm curious where did this StraightTalk sim come from? Did it come out of a StraightTalk phone or was it ordered off their website?

Thanks for the reply... appreciate the help/direction.
Nothing appears in the APN list. It doesn't work for StraightTalk at all... no calls, text or anything. I'm guessing the SIM came with a StraightTalk phone but I'll have to ask my friend to be sure.

There's the problem. A sim out of a straight talk phone will not work. He will have to order one from their website and have it activated.

I'm assuming that is it then. This sort of thing makes me CRAZY! I will buy a SIM from the site (this friend of mine is past the age of online buying)... thank you for your help... I'll post how this goes, for future Android newbs like myself.

Keep in mind that I could be very wrong but I am on StraightTalk myself and have never had any issues with the sim I ordered. And considering that you had no troubles using the phone with your sim then I have to assume that's the case.

If anyone has any input on a SIM card from a phone package not working on a different phone, please let me know. It is about $20 after tax and shipping to get a SIM. We are thinking of just going the prepaid ATT route instead.

Well with StraightTalk they lock the sim card to the phone it comes with. So even if you had two phones from them you wouldn't be able to just trade out the sim card like you can with ATT or T-Mobile. Now if you get one of the sims off their site those will work in any ATT or unlocked phone.

Just got my brand new StraightTalk SIM in the mail and activated it online. It worked perfect. HSPA and 3G worked, I could text and send picture messages. The phone is ready to go!
Thanks for your help!

test the sim in another phone.
if good, change to another modem file known to work with ST. see stickies in captivate development forum for modem list and links.

After making sure you have a working modem (ugkg3 works great for me) you'll want to check and make sure you haven't lost your IMEI. It happens sometimes when you flash custom ROMs and that will prevent you from getting any service.

no cell coverage on straight talk with cyanogenmod
I have a galaxy s2 i727 with the cyanogenmod 10.1.2. I am a caveman newby (over 50) and i am not able to get more then 1 bar on the cell coverage and not able to make calls. Does the cyanogenmod effect cell coverage? should i use different apn settings? the wifi works perfectly well and i have received some texts. I live in nor. Cal and i believe straight talk is using att lines.
any help would be awesome!

The old one is the att.mvno APN but I deleted it so if u need that one you will have to search....
I would also search/ read about modems and what one may work good for your area. There are numerous threads (some stickied here) about modems. Try the APN first though to rule it out. After you make the new APN save it, select it, and reboot.....
Edit: I see you also have an s2 not a captivate so don't flash anything from here....

Also the APN will not prevent you from getting signal and receiving phone calls. So if you can't even receive or male calls you need to look into modems for your s2.
And a little more specifically in regards to the last post the two different apns depend on when you purchased a sim card from them. If you got one in the last year or so it will likely be the tfdata. If older it'll be att.mvno

What wasn't fair was when I lost my data and no one at ST could tell me why!! I had to read way more than I wanted to...From other posts around the web on the subject led me to believe the change was more to do with the 4g/lte towers. Seemed like at some point some users were forced to change to the new apn because they lost even 3g data using the old one.
Some have also posted about when traveling through certain areas, they had to change just the MMSC/MMS proxy back and forth between old and new to keep receiving mms.:silly:

Turn on shamu's AT&T HD Voice

Ok, I got the Samsung Gear S2 watch which runs on 4g today thinking the Nexus 6 at least had HD Voice because the 5 did and you have to have it to connect to A&T's NumberSync or it wont work on 4g and its useless. Anyway, I got everything to work except I couldn't get it to connect to the NumberSync with the error "We are sorry. We cannot set up NumberSync because your device does not have HD Voice...." I called AT&T and they asked for my IMEI number and that will tell them and they said it must not have HD Voice. Is there some way I can get this enabled on this phone so I can use this?
Thanks!

and what does hd voice have to do with Volte??? Volte = voice over lte. without volte, lte is only a data line, with volte it is also a voice line.

Heck if I know I just said VoLTE and she said yes but the error said HD voice... Ill change the title

if you make a call on lte, and you have voice, then its on.

Im not sure if the phone has it. I keep reading Verizon version does but AT&T dont at the time. Here is someting else. I thought she said my phone was coming up as something else but the IMEI number I gave her was correct or the same as I read off.

if you go to the main settings, more, cellular network, turn on enhanced 4G LTE mode.

its the same phone on all the networks, but i guess it might not be capable on every network(depending on their methods). anyways, it has hd voice on tmobile as well, not just verizon.

Whats weird is i dont have the option to turn it on in my phone settings and its an unlocked phone. The setting to turn it on/ off is there if i go to *#*#4636#*#* but the button is set to on and wont switch back and forth. There is supposed to be a nother setting under More/Cellular Networks/Preferred Network Type called extended and mine isnt there.

Does your phone company support VoLTE on this phone specifically?
The various Android 8 roms should support it if it works on stock. But many telcos check the specific model of the phone, and only enables it on the models that they have approved.

I'm on a AT&T MVNO (Red Pocket Mobile) so I don't know. But if you're talking about the backbone (AT&T) I still don't know because I believe my N6 was purchased from Google. I'm pretty sure AT&T branded N6's are approved.

Anyone flashed any other carrier rom?

Here is a list of them from sammobile
https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/
I think its going to be a free for all and maybe we in the verizon s8 will get love from the whole community this time, at least the US. It seems we all may have SM-G950U.
Is that correct more knowledgeable people?

I'm trying to flash to T-Mobile​ as all US networks use the SM-950U . That means they have all the bands for every network. I tried to flash through odin but if you flash the CSC file for T-Mobile , along with the other 3, the phone factory resets to stock Verizon firmware. If I just flash the AP (Actual software) and the CP (Modem file for correct bands), it works but I get a ton of bloatware from cricket, metro pcs, Verizon , and tmobile with a really glitchex out settings app. Also, without the CSC file your phone is still technically Verizon .

So we should wait? I have the Verizon version also but use TMobile.

We have to wait

I tried the method used on the S7 to flash another carrier and it does not work anymore. There's some type of carrier partition that can't be changed by odin with the CSC file, which would change that partition. If you try to flash all the files, you get an error at 32% of "upgrading your system". I heard that there is a new version of odin that lets you flash the userdata file to switch carriers from a other forum, but it's not out right now. So waiting is the only option....
Here is a forum post for the S7 edge:

Just we'll have to wait till someone figures something out. On a side note, what's the most recent update? I'm on QD9 and I'm getting an update notification for the dqa OTA fix from Samsung but I can never download it. Probably because I'm using Verizon phone on TMobile...

The latest update is QD9 and if you want to check and install updates, you can download Smart Switch from Samsung's site. Then you go to more and software updates to make sure your phone is on the latest version. I'm also on T-Mobile with the Verizon model and hate that I dont the Voice Over LTE, Wifi Calling, 4x4 mimo, etc. So yea, we just have to wait for someone to figure this out.

Maybe I'm looking at the wrong thing but that Samsung switch program seem to be for transferring data from other phones so I didn't bother downloading it.

I thought the same thing but along with that you can perform software updates for any carrier. Also, I recommend d doing a backup if you want to flash another carrier when it is possible.

Wow that was a pain in the butt to install. Had to install a 2008 version of visual c++. Since I don't see an option to update the phone, is safe to assume there's no update then right? If so why do I always get the update notification?

Hi there, do you get LTE with t-mobile on this Verizon unlocked version?
I am asking because I grabbed one as well and I am on at&t but I can't get LTE going. When I boot the phone, it is there but within minutes, it goes to HSPA+, I tried every which way. I called at&t, gave them my IMEI and everything but still no LTE unless I reboot my phone every 5 minutes.
Thanks

You need to have the correct APN settings. I believe Verizon has the most LTE bands so it should work with basically most of the world's providers.

You don't have the correct bands enabled with a Verizon model when using AT&T. Verizon only unlocks bands for it's network, but tmobile shares a couple of these bands and it's it as big of an issue. At&t does not share many bands with Verizon so the phone may be struggling to even find one LTE band. The only solution would be to flash the phone to AT&T firmware, which is impossible at the moment. (I Tried)

Is there a way to force a certain band that exists both on verizon and at&t? If I can't get this going, I might have to just sell the phone. I have couple more days of patience left

You would need to find the firmware of an AT&T s8 and flash the CP file (Modem) using odin. This should unlock the correct bands. I did this on my Verizon s8 as I use T-Mobile.

AT&T Firmware On SM-N950F

Hello there, I have an international Galaxy Note 8 that I am currently using on AT&T here in the States. I have only been able to get H+ (3G) and using the NextGenPhone APN will not connect. I was told by AT&T that I need their firmware running on my device in order for it to work. This is a little frustrating, considering I bought this phone to avoid AT&T's firmware and locked bootloaders. Will installing this firmware lock my bootloader? I currently have it unlocked and rooted and do not want to brick it. If anyone has tried this let me know how it went and where you got the firmware from. Thanks!

The att firmwares are made specifically for snapdragon devices, so, an att firmware will not even install in your exynos F model, sorry man…

Which csc you have selected with your international N950F device
The US csc for AT&T was available on your firmware?
Don't be afraid to hit the "Thanks" button if someone helped you. It don't hurts

Since he is rooted can he just flash the at&t csc using this:

Thank you for your reply. I tried your suggestion with some "success". I installed the ATT CSC but I am still met with the same issue, except now it reports that I have 4G instead of H+ (although its the same speed as before). My preferred network type is UTMS/LTE which I believe is normal. I am currently using the ATT Phone APN because NextGenPhone will not work. Any suggestions?

Do you know the frequency bands that your network uses and does the note 8 support them?
Maybe try another usa carrier csc might have better luck.

I don't think you will get LTE speeds unless at&t provisions your imei number. Same as using an unlocked t mobile USA model on at&t. There is plenty of threads about no 4G or LTE signal on stock unlocked handsets on here. I don't believe your issue is unique to your device being an F model as opposed to U.

Mate, if you get 4G, you should be fine! 4G and LET means the same.

LTE is actually the technology to realize the 4G standard.
So if your phone is showing 4G you should have your fast speed. But also H+ have a great speed.
If the speed isn't fast enough, maybe it's limited by your provider or location.

I don't think you will get LTE speeds unless at&t provisions your imei number. Same as using an unlocked t mobile USA model on at&t. There is plenty of threads about no 4G or LTE signal on stock unlocked handsets on here. I don't believe your issue is unique to your device being an F model as opposed to U.

When I called AT&T I told them the IMEI number needs to be provisioned and they attempted to get me to install their firmware, which failed because my phone is rooted and blocks updates (among other reasons). Is there any other way I can get them to do it?

The AT&T firmware installation don't failed because your phone is rooted, but because it's a completely different firmware! The US models are devices with Qualcomm's Snapdragon SoC, while the international (F) version have the Samsung Exynos SoC.
So you tried to flash a wrong firmware version for your device.
Be happy installation failed and you don't bricked your device by flash wrong bootloader!
You wrote, you have 4G now? What you want more? With a rooted device you can change the showing icon like you want.
Here in Germany since i got note 8, for me it also shows 4G instead of LTE in statusbar. Before it always shows LTE (same SIM card, same provider)
(The screenshot is showing an entry from DeluxeRom v.7.3 custom Rom where you can select which icon you want to see)

Does your F model show 4G ? If so, as what the other person said is correct. The F models show 4G symbol instead of LTE.

It only shows 4G after flashing the AT&T CSC. Prior to that it showed H+. When I open Speedtest.net it shows my connection as being 3G in the app and my speeds are still extremely low. 3mbps download and 0.5kbps. My Note 4 on LTE would do about 30 up and down in this area. To use LTE I would have to use the ATT NextGenPhone APN which does not work for me. I have to use ATT Phone.

All I know is that at&t doesn't allow high speed connectivity for imei numbers not on their system. There have been many posts on here with people with non at&t devices having slow data speeds.

If your device is rooted and you flashed the csc selection changer you should be able to select "LTE only" into connection settings.
Select it and test your speed again.. maybe the signal strength it bad at your testing location

Device Info screenshot

Those with AT&T branded phones with Video Calling working, can you post your Device Info screenshot.
Screen can be done via phone app and dialling *#*#4636#*#*
I already flashed the official At&t fw on my unlocked N9 and still could not get the video calling to work. At&t support says I am already prvisioned but device info says no:

WiFi calling works for me too. But not video calling

Wierd. I can't open device info using the code. Exynos version doesn't have this?

Yeah, I know.. I've been using this code since gingerbread. That's why I was wondering when it didn't work on this phone.

..and do those with ATT n9, does your advanced messaging work, like u see as they type?

So it seems like RCS and video calling doesn't work for U1 devices on ATT , T Mobile or Sprint. Just WiFi calling works.
Would be interesting to find out if flashing to the appropriate U firmware enables them or not.

No dice. Tech support will send me a new sim (also 5G enabled sim hehehe) but currently my number is already registered with my old Note 4 and everything works except video call and advanced messaging.
Does anyone here with unlocked/non-ATT branded Note 9 able to get the Video calling and advanced messaging to work?

My research concluded that the unlocked usa devices don't have video calling or RCS messaging enabled with any carrier.

Those with att branded ones can u pls post this screenshot
Dial *#77467#, click "IMS registration" then "ATT VOLTE"
I'm interested on what "Services" say
Thanks

Thanks! So that's where the difference is

My test results:
IMEI filter is disabling the provisioning on the non-ATT BRANDED phones.
What I did:
Put sim card on ATT branded phone, in this case an old Note4. Wait few minutes..
Try video calling wife.. it works!! Try RCS, worked.. well, this is an Att-branded n4...
Pull out sim, put it on unlocked Note9, even with ATT fw.
As soon as you have cell signal, do a video call.. IT WORKED!!
Wait a few minutes for provisioning to kick in.. phone will report IMEI to ATT. ATT finds a non-ATT branded n9, and will disable the video calling. Video calling now fails
So while phone has not yet fully registered in IMS, video calling worked. As soon as ATT finds out it's a NON-ATT phone, the extra services will stop.
So basically, they do filtering on their end. ATT level 3 tech support is clueless on what I was talking about. So there you go, no dice here..
