[Q] Voice + 4g on the T-mobile Samsung Galaxy Tab ???? - Galaxy Tab Q&A, Help & Troubleshooting

saw this guy on youtube
my current knowledge of t-mobile tab unable to do voice+3g on t-mobile.
only voice+edge when flashed to euro rom. or 3g only data plan from stock tmobile.
but this guy from youtube says he now know how to do 4g + voice on tmobile tab.
he dont give out any info but video of his phone.
saying he have done it by learning in xda.
changing modem and imei #..
i am currently getting only voice + edge, if this guy is right.
please help me and lead me to instruction of somekind.
give me modem and how to change imei?
thanks

I see he is running GB.
Can we do the same with CM9 ICS?

Changing IMEI is illegal in some countries and against xda rules (I think).

It is illegal in UK but not in USA so I heard.
That video has no credibility.
Rotohammer who did a lot of research on it never got it working.
And if the video guy is so great why he didn't at least show us the baseband ? Is not hard or illegal to show his baseband. Maybe to show his imei is grey area, but not baseband.
People asked him and he didn't reply.

Actually, i think he's right. As i suspected earlier, tmob is throttling data based on imei#. Changing would take care of it. That being said, if you change your imei you risk being black listed by carrier. ie.no service

[Q] Can AT$T tell if you're running a custom rom?

I need to call 611 and gripe about some issues i'm having with my cappy. Does anyone know if at$t will run any sort of diagnostics remotely that will alert them that i'm running serendipity?

Nope. When they check up, it's usually just the IMEI. They ask what you're using (KB1, JH7...) but they assume most don't even know what that means or where to find that info.
I recently have called them from my phone and they didn't mention anything about it not being stock. When I look at my account online from my computer it still shows the captivate.

I'd be careful with Cyanogen though. When I flashed Cyanogen, I received an e-mail from Google saying "Welcome to Nexus S!". I didn't check, but I wouldn't be surprised as AT&T started listing my number online as a Nexus S or some other random Android phone that isn't the Captivate.
In fact, that same question occurred to me today, because I'm running Cyanogen on my HTC Inspire and I need to dial in so they can set up my Voicemail (for some reason, whenever I switch phones my voicemail gets screwed up).

Are you sure you got it on cyanogen, and not on supercurios port? Because the cm rom has correct model numbers, where as supercurios port is a direct rip from the Nexus S.

The email you receive is not from at&t and is just because the rom uses nexus s market foot print.
Sent from my Captivate using XDA Premium App
The answer is almost certainly no. There is a capability using device management tools to report back ROM details but right now the care reps don't have any access to it or any procedures that use it. They don't even have access to your IMEI so don't worry about custom ROMs unless you are physically returning the device.

What's more, based on my experiences with the Customer Service reps, most of them wouldn't care. The Front Office might, if you had to send in your phone, but every CS rep I've ever talked to has been mighty laid-back about the "rules."

I realize that. But because of the fact that it uses the Nexus S market footprint, it would also (logically) use the same Nexus S footprint over the AT&T network. Otherwise, what you said makes no sense.

Oh gosh that is so far from wrong it's not funny. "Care reps", otherwise known as technicians who fix your problems have every right to access your IMEI number without your consent. Your phone's IMEI is stored by AT&T as a ref number, and can be accessed from the AT&T database at any given time, even by the technicians.

There is an IMEI record for the device you purchased NOT what you are actually using on the network. There is also a TAC reference collected by OTA whenever the SIM goes into a new device, but the care reps (industry standard term, btw) have no scripts using it as far as I know. For example, AT&T still reports me as having a Bold 9700 on my 1st line when it has actually been a Cappy since August. Bottom line, AT&T generally doesn't give a crap what device you use.

Happened to me....I never used supercurios...only CM7.
Fot the OP I doubt they can tell....even less they don't care. I used the sim from an old Sony dumb phone in my old unlocked Nokia N79...and used an unlimited data plan for $15 and tethered.
So yeah, don't worry.

~~important~~ null imei (0000000000000000) bug

I dont know if any other guy here went through this hysterical problem but yeah would like to inform those who flash more often without surmounting about thinking before doing it..
Also dev's i think this problem should be rectified immediately! !!
Here's what happened with (not so)lucky me
I flashed cm9 beta 2 directly over cm7 by tj_style..(edit wiped out data and dalvik cache too) and then after installation found out that my IMEI no. was null(0000000000000000)
Tried every possible legit method to restore my IMEI back but to no avail.
Googled everything but sooner got frustated
In the end i ended up in the samsung customer care center, acting all dumb like i had no clue about my phone and then there was my phone without imei.
I told them(care center ppl) that "last time i sent a text to a friend.
The next day i checked my cellphone , there was no signal coverage."
You know pretending like i had no clue about what the hell was happening and made out stories.
The funny part was that the center people believed everything.
Finally they took in my phone and gave it back after 2 and half weeks(after constant inquiring about my cell xD) & finally i had my original IMEI restored (salvage)
.
That was about my problem.
Still can't figure it out how my IMEI got washedoff adter flashing cm9 beta 2..
(Sigh).... .. but now I'm on the safe side. ^^
So i think its serious matter about wiping IMEI.. and it should be considred under attention.
Comeon guys i think this post needs atleast more discussion than this xD
Lol show some decency! !

what is IMEI on a phone ?
IMEI(INTERNATIONAL MOBILE EQUIPMENT IDENTITY) no. is a number, usually unique, to identify GSM, WCDMA, and iDEN mobile phones, as well as some satellite phones. It is usually found printed inside the battery compartment of the phone. It can also be displayed on the screen of the phone by entering *#06# into the keypad on most phones.
The IMEI number is used by the GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing the network in that country. For example, if a mobile phone is stolen, the owner can call his or her network provider and instruct them to "blacklist" the phone using its IMEI number. This renders the phone useless on that network and sometimes other networks too, whether or not the phone's SIM is changed.

Looking for a way to use a Captivate on non AT&T US networks

Like the subject says... if someone can point me in the right direction, it would be appreciated. Not at all sure where to start. I can run pretty much whatever Cappy kernel & ROM I want, including different modems. Just wondering what the technical issues & tasks would be. And, of course, I'd need to know which, if any, non AT&T networks would work on the Cappy.
The Captivate will work on T-mobile, but because of the frequencies used by T-mobile u can only get the Edge on their network.
As far as other non att networks, u will just have to search and see what frequencies they use and then compare that to what the Cappy runs on. :thumbup:

The phone must be unlocked, and you can do that for free here: http://forum.xda-developers.com/showthread.php?t=761045
When you SIM unlock it, it can work on any gsm carrier like AT&T, T-Mobile, Vodafone, and most other international carriers
I am running it on T-Mobile but it only gets Edge.
If you perform a sim unlock your can always put it on a mvno like Straight Talk or Red Pocket. You can use HSPA on those instead of slow edge.

[Q] i9305N LTE not working

Hi there! I'm sorry if there already is such a thread but I couldn't find anything quite like this.
I bought this i9305N second hand and it had the famous IMEI problem 00/02. I went to a service center and there they were able to restore the IMEI of the device. And the phone was able to connect to the 3G as normal but not the 4G network. I've never seen the 4G working on this phone and have no idea what to try. What I tried was:
different modem firmwares.
flashed CM 10.1 and again tried those modems.
tried to set the phone to lte only via the *#197328640# code.
I think that in Sweden this phone is supposed to work on only the tele2 and telenor 4g network. I've tried sim cards from both operators.
Has anyone experienced something like this? Does anyone have an idea what is happening and what I can try?
Thanks in advance.
Does yr provider support 4G?yr sim card support 4G? If all above Yes then yr area doesn't support 4G or the coverage of 4G very poor till none.

Just out of curiosity, have you tried cards confirmed to be on 4G-enabled contracts? I had to call Tele2 and ask them to change my contract over to a 4G one before I would receive 4G speeds. Another silly thing you could check is if the phone is actually connecting to the 4G APN, for Tele2 this would be 4g.tele2.se.
Hi! This is the thing! I havent found a card with confirmed 4G on it. I was told that sim cards on contract have 4G enabled on them. I was wondering if there is some sort of a tool to scan networks around and see information about them like what freq and speed etc... I am using my comviq card now in the phone with the apn that you mentioned and that was set automatically as the phone is with the tele2 firmware. The most brutal thing was when I went to the tele2 office and asked for a 4g activated sim to try on my phone and they said that they don't have any!!!! I went to the telenor shop and when I asked for a demo sim card with 4G so that I can test my phone and he gave me a 3G prepaid card. After 10 minutes of changing settings and stuff on my phone I asked him if that card has 4G on it at all he said - no, its just a 3G. I am going a bit of topic but my point is that it is extremely hard for me to find out where the problem is.

Find someone with a 4G contract and ask to test his SIM in your phone.

Hi.
I live in the "kära grannlandet" Finland and i had to call my operator to put my i9305 as my active phone.
(They change the ownership of the phone on their computer)
I bought my phone 2hand but it was factory sealed new. operator locked to the same operator that i use.
The phone was "active" to somebody else without 4G so thats why it didnt work for me.
Hope this helped at all..
Lycka till!
My friend had similar issues with his S2, I went into the phone options menu using the #xx# number and the phone itself was not set to lte mode. I am sure you can find the menu codes somewhere on the forums as I don't have them memorized. It is worth checking if you have not done so.

[Q] P1 tab (T-Mo) Update question

Hey all I have a rather Noob question for the Galaxy Tab (p1) people.
So what is the difference in the roms for all the different tabs? I see a lot for the P1000, P1C, P1N etc etc.
Anyway I just got this tab from a buddy and I would like to get it off of froyo. He said that he had it on CM7 or something like that but revereted it to stock before he sold it to me. Anyway it is rooted, but has stock recovery, and froyo......
I would like to get it to the most recent stable CM available. It's going to my wife and I'm not going to be able to touch it again...... I have my TouchPad and GS3 to play with.
anyway I haven't seen any good guides on how to get this beast updated so could you please point me in the right direction, I've been searching but probably in the wrong places.
thanks.
Steve
The difference is where the tabs are from. Ex. P1000 is europe (gsm), p1000L is latin america, P1000c or P1C is usa- verizon/sprint(cdma). I dont remember the t-mo type. T-mo is gsm though. To find the right cyanogen mod rom type in the model. The verizon tab is sch-i800. should be on the back of the tab. Have fun.

I have a sgh-t849.
Treat it like a P1000 especially if you aren't going to use it with T-Mobile network.
If you do, beware that you only get 3G with t-mobile modem and no voice call.
Or you can use JPZ modem to get voice call but only 2G.
