[Q] So what am I doing wrong here? - Galaxy Tab Q&A, Help & Troubleshooting

I have a Galaxy tab from TMobile, I followed the directions on how to make it a phone here dub dub dub dot youtube dot com/watch?v=9oADoLHWHH4 It all seemed to go without a hitch but I cannot make phone calls or get data access (wifi works well though). At one point I was able to make one phone call and send two texts, but it all stopped and does not work. At first I thought it was a reception issue. Then I reflashed it with the euro roms, all in an attempt to get it working reliably.
After doing the above procedure I did sometimes get the edge icon to show up, I can see data going UP but the down arrow never seems to change color (I think they are supposed to change colors).
I have an AT&T SIM, could that be my problem? I do not get a message to eable the network, so the system is unlocked (I think).
SHould I sell the tab and get an AT&T tab? maybe that will have better luck?

I am starting to thing this is an issue with a blocked Emei number.

Can you borrow a T-mobile SIM to try? That would prove if it's a SIMlock issue & also prove the hardware.

[Q] I have tmobile, with Data plan, but does not work on my G1

So I've done plenty of searching, enough so that I was able to unlock my phone without the data working, rooted my phone, flashed and modded it, successfully running newest Biffmod.
That being said, i'm 100000% sure I have a working data plan, my plan is unlimited everything.
Works fine in any of my other phones, Dash 3G, HTC HD2, Unlocked Samsung blackjack i607.. The difference, those are all windows mobile phones?
But the HTC HD2 Dual boots android 2.2 froyo and data works there.
Yup, same sim I'm talking about, same plan, just different phones.
Any Idea why my data plan is not working with the G1? Am I doing something wrong? It worked when i FIRST got this phone (ordered it off ebay not that long ago to play with).. After factory reset/wipe before modding is when it all went sour.
Was stuck on log in screen so I had to do the work around to get into the phone, obviously not with Biffmod I can skip.. But I cant use market place, check e-mail, ANYTHING data related. Yet my Icon says 4 bars, 3G and I even see the "up" and "down" data xfer arrows giving me activity.
It's as if it's "there" just not working.
Any help would be great appreciated, I plan to go to T-mobile and hopefully one of the people there will actually have some tech savvy.. Wishful thinking.
Long story short, I just want my data to work. Please, and thank you.
Do a search on here for the correct APN setings for your provider.
edit: here's the thread http://forum.xda-developers.com/showthread.php?t=475564
Read the thread, it's for ATT users trying to use a T-Mobile phone.
The issue is that I actually have T-mobile.
I'm fairly sure I saw the apn settings for t-mo in there too. That's probably what you should be checking first.

Just google Tmobile's US apn settings or grab them from another of your devices, then it will work.
Perfect, I'll give that a shot when I get home from work today, thanks for all the help so far.

Atrix HD - Having intermittent signal loss using Straight Talk.

The wife and I have Atrix HD phones that we bought used but in great condition a couple months ago. We purchased the Straight Talk at&t compatible micro sim kits from walmart.com and set up our service. We previously had Samsung Captivates also on Straight Talk and they worked flawlessly. I put in my APN settings and I get data and MMS perfectly but occasionally I get a red triangle where my signal bars should be and my phone says "Emergency Calls Only" and I will wait 30 seconds or so and my signal returns. There is no steady decline in signal that leads up to this. It goes from like 4 bars to a red triangle with a cross inside it.
I live in a fair sized town and have always had 3 or more bars of at&t service with phones in the past so I do not think its an issue with poor coverage. I am attaching pictures of my APN settings.
Any help would be appreciated.

I'm having the exact same issue since switching to to the 4G LTE micro sim. It only seems to happen on mine when I'm connected to Wifi though. I get the red triangle intermittently. This never happened to me until I went from the old sim to the new one. Can't find anything on it yet.
same thing
The same thing is happening to me here as well but using a Net10 LTE sim card (same as straight talk basically). I notice it the most after I complete a phone call. It takes a minute or two to regain service again. This is really annoying. Would like to see a solution to this problem.
So I worked with Straight Talk support for about 5 days, back and forth, bounced to several reps throughout and nothing substantial has come of it. It seems a little better after they made "adjustments" to my account as they put it, but I still get disconnected from mobile data when on wifi.
Don't get me wrong, their support people were very responsive and seemed to genuinely want to help me, but in the end they said "your ticket has been open for more than 24 hours so it has been closed. If you continue to have issues please open a new ticket." Anyone else have any luck on this?
I also was having this problem found that if you edit existing att apn (phone needs to be rooted)with sqlite editor it seems to work fine.
tether also works fine this way.I am still not able to get lte to work with straight talk even with new sim.
Just to follow up. As usual, it seems with ST support, one rep tells me they have some things they can try once I call back on another line and then I get a new rep who says nothing can be done until 10 people complain about the exact same issue I'm having. I'm assured this is an isolated incident...
I went ahead and purchased a new SIM card (looks different than the first LTE card I had) in case I had a faulty SIM. Worked flawlessly for a day and now it's back to the same issue of cutting out completely throughout the day.
same problem here on wifi get red triangle (especially after phone call).
More since i switched from 4g sim card to lte sim noticed that data disconnect from time to time like make impossible to watch video flawlessly...
with old 4g was yes only 4g but never loss a bite....could watch anything also streaming tv.....now it is impossible.....
the end of the month going to switch to old sim and see if the problem is in the new sim cards they tried may be to limit access or is in the new service doesn't matter what sim card you possess..
we'll see...

Switching to my old sim was my first thought to. However when I tried it didn't work. I called ST and they informed me that once you switch sims, the old one can never be reactivated. On top of that they don't offer the non LTE sims anymore. Such a pain. Hope you have better luck though.

Some one could correct me if I'm wrong here but I'm pretty sure this is a result of ROMS using a 4.4 rom. Modem crashes. If you want to test it run a Stock ROM... If you are already using a completely stock ROM then Idk what to tell you. But same thing happens to me using any version besides stock. And yes only when on WiFi

I'm on a 100% stock ROM, I haven't unlocked my boot loader, just rooted.

Then unlock your bootloader and try flashing different radios from the different stock fastboots we have. Depending on the fastboot I can have next to none or almost full in my bedroom. For me, ATT JB is in the middle, JB Mex Retail is the best, Bell ICS is the worst. ATT ICS was about the same as ATT JB.

For the time being, I just switched to Aio and so far so good with LTE coverage and no disconnecting issues. If they return I'll try different radios as you suggested.
So I've been with Aio for about a week now and everything is working great (knock on wood). I've had 2 mobile data drops at work with Wifi turned on, but they only lasted for a second and I do have really bad reception here inside the building. Outside of that no issues at all so far. I'll update if anything changes.

[Q] at&t using google voice voicemail with straight talk

I'm using straight talk on an at&t s6 edge. Trying to get the google voice voicemail to work. I've tried the mmi code **004*gmnumber# to activate conditional call forwarding, but I always get "couldn't get server response".. Trying to change the voicemail service provider also gives errors. "Can not read data. Network or sim error"
I have tried the individual mmi codes for different kinds of conditional call forwarding, but get same error:"couldn't get server response".
I have read that at&t controls the conditional call forwarding service, being the original carrier for straight talk, but because I don't have an active account, they can not change features for my number.
The ST rep tells me that there might be a hardware specific mmi code that Samsung may provide?
Does anyone have any solutions?
Thanks guys,
Gozirra
Gozirra, I was having a similar problem with my iPhone 6 (on AT&T) and my S6 (on Cricket). I think it may wind up being these phones (both are AT&T branded). I wound up swapping the sim card into a spare (Cricket branded) Moto G LTE and the MMI code worked without issue.
This exactly what I just did and it works. For months I have been trying to forward my Cricket voicemail to Google Voice, from Samsung S5. I couldn't. I called Cricket, they said there's nothing they can do. I then I saw gm2racer's post, used my sim card in my son's Samsung Prime. Voila.
Same issue here with S6 active + straight talk and with youmail as well.. invalid mmi.. straight talk says they dont support conditional forwarding, however 3 windows phones prior all worked on ST (both att and vzw phones)..
Frustrating enough i'm considering switching to tmobile (not willing to switch phones per say, i just got the s6)
I know this isnt the most hit thread on this topic, but today I resolved my issue... I have an AT&T (unlocked cause its older and paid for) Galaxy S6 (SM-G920A), that I simply plugged in the cricket SIM from my older Cricket phone and started using on their network. I got the immediate system text messages that reconfigured most of the call settings and the phone worked fine but in the past couple months, i keep getting complaints that i dont have voice mail set up from callers.
I did, I do, and I have used my google voice number for years now, and use it for my outbound calling (install the gv app and have it set outbound for all to GV). I also use GV as my mailbox... and I know how to use the **004 string to change forwarding (conditional, as in when you dont answer, cant answer, etc).
But with my AT&T S6 and the MM 6.0.1 (DQC1 official AT&T rom) - that 004 string wouldnt work. Neither would changing forwarding settings from the phone settings. They all state they cant talk to the server... and theres no option in my call settings for voicemail to set voice as the handler (versus your carrier).
So I was kind of stuck.. and here is what I did.
I flashed it using odin to the sm-g920aZ QB2 firmware (as in , the Cricket firmware for the S6, 6.0.1 MM version in March 2017).
I know.. it is taking a risk as some people state it doesent work.. some do.. well.. mine did. And since I have never tried to get root or do a custom OS, i am still official (thats all I have ever flashed, was official ROMs), and galaxy pay works, and the phone works, more or less perfectly from what I can tell. In fact, its got a TON less bloatware running a cricket ROM vs AT&T ROM.
And lo and behold, call forwarding works great now. And I actually got a firmware update notice from cricket 5 minutes after it was flashed.. and, well... all I can say is COOL.
I would probably stay with a MM (6.0.1) version of the ROM or match whatever you have now. I understand once you go to nougat, you cant go back to MM, and that may be true for moving between carrier ROMs also.. (cant go from Cricket 7 to at&t 6).
Anyhow.. Ive done a ton of research on this and thought since XDA helped out immensely (thanks everyone for posting roms and such), I would give ya'll a heads up that this worked for me.
I might go ahead and take those cricket firmware updates OTA. I know its a risk, as my phone is really a 920A (it shows as 920AZ now in settings also), but I really think its the exact same hardware... if I brick it I'll let ya'll know.
Confirmed, updates are good.

I let it go ahead and apply all of the recent Cricket updates to the S6 (920AZ) and confirmed its been running fine for 2 days now with no issues and no loss of functionality.
Makes me wonder what setting was changed by the cricket firmware - that allowed call forwarding to work properly and be set/reset/accessed by the device? The network and device didn't change, just the firmware.. but I dont see anything in the APN settings that relates to voice mail (maybe its something else that needs to change to allow CF settings?)
ANyhow.. your mileage may vary.. and Cricket firmware is WAY less bloated than AT&T for sure!

Galaxy S8 financed blocked?

I bought a used t-mobile galaxy s8. The website I used said clean imei and I put my sim in the phone and it worked fine. After taking it home it stopped working. I played around with the settings to get it work and came to find that it works briefly after turning phone off and then back on. After about 10 minutes I can't make call or even perform a speed test via speedtest app. The dialer screen will not even load and remains blank, then no calls incoming or internet. If i restart then it starts again. This made me suspicious and I eventually found the t-mobile imei site which says it has an outstanding balance and may not be able to be used. I just find it weird it works then stops. Is that what is causing it? Will it eventually stop working completely?
call tmobile and describe your issue. they can help or at least tell you what to do.
OP, where did you buy the phone from?
I purchased one from S**p*a and have similar concerns.
I recently had the same issue.
I found out somehow an option was enabled that made it seem like i was network blocked or had a bricked sim card.
Under settings/connections/more connection settings/wifi calling
Make sure the middle option is selected and not "never use cellular network"
For some reason every samsung phone i have owned has enabled this option atleast once during ownership.

GS6 Active Network Issues Unlocked

Hello! I Had my Blue Camo GS6 Active 64 Stolen last sunday, Bought A White GS6 Active 64GB Model to hold me over and its in real good condition. But its Network Unlocked and noticed the setting on my 32GB Black And my old Blue 64 phone were set to GSM/UMTS. This for some reason is stuck on WCDMA? I Don't even see a GSM/UMTS Option and was wondering what i should do here?
I Did a few system updates thinking it may automatically work but whoever had the phone before must of changed something, even a Factory Reset didn't solve the issue. So i get the phone in the mail, power it on and everythings good no SIM yet but it had 4 bars, Pop in the AT&T SIM and restart and bam No Signal at all. I Changed it to GSM And get nothing. I Notice if i set to LTE/UMTS When i'm up the road it actually pops up 4G LTE And works too! But i get home and Poof No Bar. Its probably cause it usually does get knocked down when i walk inside to 4G But never no bar.
Anyway i can Flash a Stock OEM Modem? Or a way to force the Network settings to Reset to OEM? Had this... well that GS6 Active for 3 years never had an issue but mine was AT&T Network Locked i never unlocked it. This is Network Unlocked and notice a lot of what seems to be Foreign Networks? Network settings I've never seen before that's for sure.
Help will be appreciated!
Really need this to just work by Monday and AT&T Support sucks lol! Best buy couldn't help me, 3 AT&T Stores couldn't help me cause they don't sell it anymore and i didn't buy from them. But i know its fixable i mean i get signal if i flip around to the WCDMA Setting when i'm home, And before i walk outside i hit LTE/UMTS and i do get a 4G LTE Signal when i get up the street. but i'd rather it Automate like it did before so i don't have to keep doing this.
Yeah this sucks, Like Mint White 64GB S6 Active. Just this i didn't expect. I've Switched sim cards back and forth, took the sim out and tried to change the band but that doesn't work. I've gotten to the Network System menu and put everything on Auto. I Have it set to LTE/UMTS and i get nothing, i take the SIM Out and restart, 4 bars are there. put the SIM In and Boom no signal. I've tried to change the GSM/UMTS Band to Automatic but it just says Unsuccessful. But i have that feeling if i can get it to say Successful it will work.
Anyway to use my laptop to connect via ADB And Force the band to change to auto? Or anyway to get it to stick to Stock settings? I Still suspect whoever had this before did something to the Radio and Network settings and i can't figure it out for the life of me. AT&T sure won't help me lol! And Samsung just wants me to bring it to a repair shop. While i was actually at a few repair shops around here and they know nothing about these.
It's the only phone i'm comfortable with. The S8 Active is ok but without physical buttons it doesn't really serve me like this did... and i don't really care for Bixby button can't be customized. Also noticed Otterbox doesn't make Defender series cases for it so i'd have a bit of trouble getting a beefy case on it.
Ahhh.... i get some signal in WCDMA Preferred. Fixed a SMSC Issue so text's go out and i receive them if i move around a lot.
Signals still bad not like it used to be. Why do i get a Signal On WCDMA But not GSM Auto Or LTE/UMTS? Is there anyone that can help me get to any advanced network option's or a way to change the Band to Automatic? I Try to select Automatic Band which is the default i believe and it just says Unsuccessful.
Have you tried just refalshing stock rom???
I know you already have done this but sometimes it doesn't work first time(few have mentioned issues that took several flashes to solve it)
The reason folks are not replying is quite possible know one has any idea why this has happened.
I had an s6 Active that everything worked other then 4G and nothing worked.. It was a factory refurbed and Unlocked. And no matter what I did it simply would not worked... I returned it and go a replacement... It suggested it had been damaged internaly in someway..
Can you return yours for a replacement/refund???
Sorry am not actually able to help.
regards
Lohtse
I might return it. I figured out why messages were not sending i messed up the smsc settings lol!
Very unique issue here i see 4G pop up and i get calls and data flows. Sometimes 4G LTE magically appears and everything stops working till 4G shows up.
Pretty hard to find this GS6 Active in 64GB anymore.
If i take my sim card out and dial *#*#2636*#*# i think? Or it might be *#*#0011*#*# it brings up network options. I notice if my sim cards in that menu shows up empty. Something maybe wrongly set in there but not sure how to tell. Never found a way to successfully set the GMS/UMTS Band. And with no way to really root it or change anything through the pc is probably going to make this even more difficult. Phones in great condition though i dont think theres damage i believe its a network setting somewhere i missed... or at&t sucks lols! Every sense i got robbed on the 18th its been nothing but a big problem getting a phone working again.
Reflashing stock rom? Like Android 5? Its in Android 7.0.1 now. Id be interested in doing this but going back that far is spooky i dont wanna destroy it. Ive seen people say its possible and others say its not possible to go back.
That would probably work though! When i got my S6 Active Camo Blue 64gb New it was Android 5.0.1 and i think more network options were available. Then in 7.0.1 they all disappeared.
Never had issues on that phone i can't believe it was robbed from me. Not like i dropped it or lost it either it was robbed from me! Police did nothing even with the fact they threatened to kill me and everything. Police did nothing... and after 14 hour shift im not exactly ready to fight with 5 people.
