[Q] Can't connect using 3g at&t data, please help me!!

Hello everyone,
I just bought an unlocked t989 and try to use the 3g data with att ( i have the $50 unlimited all gophone) i already try the wap.cingular and the isp.cingular APNS but only get 3g icon and mms sending/receiving capability but can't connect to web, already try the *#*#.... code and select the 850 wcdma band, i don't know what can i do to get it working, when i connect on gsm only (edge) everythings works
please, any help is appreciated
thanks in advance

i have one of these for my gf who is on att im wondering how to get it working as well... any info will be appreciated. thanks!

I was going to do the same as well, until multiple managers of various AT&T stores that I went to all told me that prepaid data plans will ONLY work with AT&T's prepaid phones. In other words, even if you were to buy a AT&T Galaxy S2, and try to use it with their Prepaid GoPhone data plan, you still would not have any internet at all. Hope this helps!

Hmm, really? That's interesting. I personally have only tried it with a Sony phone myself which I put my prepaid go-phone sim card into, however it did not work. Im thinking this could be due to the fact that my sim card is really old and outdated, not too sure though.
If you can access edge on your T989 though, it should also be able to access the 3G network supposedly. Our T989's DO have the correct bands for AT&T's 3G, right?

Pretty sure you have to flash a skyrocket modem. Only then will it activate the correct radio bands.

Lets Make it happen, Any model Galaxy3 on any network?

Ok ima try to keep it as short and simple as i can. I have a stock T-999 s3 tweaked to perfection running of Net-10 prepaid with the bring your own sim. Not only that I have it network unlocked so no matter what sim i place in weather its AT&T, t-Mobile, straight talk ect. i have service, each service i can critique to its best functions. Now heres my point. I also have a US Cellular galaxy S3 , rooted, and no matter what i do or try i cannot get this specific model to run a gsm provider via sim card. Im no wiz, but i get the idea, and my idea is to take this phone that is not supposed to operate on gsm carriers and make it operate. A recent example of success doing so was with my Droid Razr Maxx HD, i was able to successfully root the phone but as you all know verizon does not support us gsm carriers within the united states , or even on their network for that matter they block it. however after flashing a different modem, i am currently running t-mobile with great service! So any talk of "its impossible" i dont need, negitivity is not needed. i am fresh to this stuff but it fascinates me. cutting to the chase, what needs to be done to this sgs3 model #SCH-R530U to make it operate and function on a gsm carrier within the United states. Hacking Manipulating and tricking is all welcome that what were all about. Ive tried several things changing to global mode, gsm only,, faking gps positions to outside the u.s. and apn settings among countless hours beyond and im at a loss.. please im open to ideas and suggestions hopefully one day we make every model capable as nevery other

I believe the issue you are facing is because that particular S3 does not contain the necessary GSM radio chip needed to use those networks.
According to this (and its a wiki so it could be wrong):
http://en.m.wikipedia.org/wiki/Samsung_Galaxy_S_III
That S3 does not have any GSM bands for 2G or 3G.
However, once T-Mobile launches its 4G LTE on the AWS band, it should work...assuming the 4G network is both voice & data over LTE AWS.
The RAZR does work cause it does have the necessary 2G/3G GSM radio chip.

Simply put, the Verizon galaxy s3 is the only variant that has both CDMA and GSM bands. So if you wanted to do what you're saying, it would be most possible with the Verizon variant.
But for what you want to do, you'll need a world phone. And I believe the Verizon s3 is a world phone. Just gotta "hack" the GSM bands. Since they aren't active by default. But your T-Mobile att s3 will never work on CDMA. Also not lte will most likely not work on other carriers.

Just curious about this. There is a lot of talk about T-Mobile S3 running/not running LTE once it starts, but what about this setting on my T999?

check this:
Double wrong. Verizon has a different RADIO frequency than AT&T and/or T-Mobile. It is impossible to update/change the radio for a sim on att/tmobile for it to work on Verizon phone. Like said before: Verizon is CDMA (code division network based) AT&T/T-MOBILE is GSM (global system network) now let me Synthesise, IMPOSSIBLE for the simcard to work in Verizon phone with out the appropriate radio for the network!

some of the verizon phones are "world phones" and have both gsm and cdma. all verizon lte phones have a sim card but only some have gsm. I don't know anything about the verizon s3 but you would be better off asking in the verizon s3 forums.

I know what world phones are. Was just stating to the other dude who thinks it completely impossible.

Not impossible. I get 3g on it and that's it. But when i change ROMs i have to redo the whole freaking APN settings again!!!
Too much of a hassle. So i got rid of it.

Yes you can, see this right now you can only get E speed on it. My S3 is actually flashed to Pageplus and I can use it with any GSM carrier here in the US, it's fairly easy to do but like I said you only get "Edge" speed for now. I've use Net10, Simplemobile and StraightTalk, any GSM will work you can also flash to other CDMA like Metro, Cricket or Pageplus.

See... This is what happens when a ignoramus tries to be smart .. You don't know what you're saying.. It is a proven fact that you can't put a GSM into a NON-gsm phone and expect it to work! (i tried it.. And it failed.. Invalid sim[in a unlocked vzw phone])
Now, this is posted in the wrong thread.

yes but havent tried
there are several places saying it is totally possible and ive called verizon trying to see what they would say and the answer i got, at least for out of the country GSM, is that the S3 comes "unlocked already" and you just put in the sim card from whatever out of country carrier you want. apparently that came with the 4.1.2 update to the phone. Now putting with a us carrier might be different but i cant try it because i have my phone flashed to metropcs and i cant just put a metro sim card in it. here a few places i found just by looking on google

U actually can use the Verizon variant s3 on tmobiles network as the s3 is a world phone, now here's where and why most ppl don't, Verizon's network is CDMA as we all know and T-Mobile is a gsm network, so with the s3 being a world phone it can be used on a gsm network but u will never see 4g or even real 3g speeds, Verizon's s3 doesn't have the ability to pick up anything but "E", edge speeds on T-Mobile so is it really worth it? Not in my opinion, if I'm going to blget an s3 I want the full functionality of the devices capabilities, just saying though lol

I can say with some certainty that u will not see 4g using a Verizon variant s3 on T-Mobile network, yes its a world phone and yes u can get it to "work" on T-Mobile but it doesn't have the right kind of internal for gsm 4g network speeds, the most u will see out of it is E or edge, 2g speeds, at least until the towers get updated

I can't say for certainty but as of right now any unlocked world phone from a CDMA based network will only pick up 2g or edge network speeds, it may say 3g or even 4g but believe me unless ur in an area where towers have been remapped u will not see anything above 2g ,maybe base 3g ,only because the radio isn't designed to pick up the gsm frequency, now in the near future cdma will be phased out so u may be able to get 4g in the future but not as of now

[Q] At&t S3 On MetroPCS LTE/TmobileLTE

Hi guys, i have a s3 i747 that has been unlocked and ready to be used on other gsm networks.
I went to a metropcs store and had the phone activated and sim card inserted, my imei was connected fine and everything went great.
I instantly had EDGE(1x or 2g) and even after hours of searching and phone calls to metropcs all i can find is APN solutions that dont work.
I currently live in Dallas/Ft Worth so i know the LTE coverage for Metropcs/Tmo is amazing it just ill not connect to LTE.
How do i get LTE to work on this device ??
Phone Specs
Has root
Unlocked
S3 i747 from At&t
Worked fine on At&T for LTE
Su keeps for closing at start because it says security issues
Stock rom on 4.3 but it says custom build under about settings for some reason.
Data speed is about 0.09-0.10mbps
Any help would be great. Sorry if this is a repost of other types of threads but i never found answers and did not want to re awaken old threads.

This issue seems popular this week.
If it's like the others, it's an issue from unlocking. the nv file gets damaged. The solution so far is to use nv-reader-writer to copy another phone's nv file and replace yours with it.

have you tested *#*#4636#*#* method? just mess around with the preferred network and see
I'm on Tmobile and worked fine with LTE

Where could i find a nv file for the s3 i747?

Sir, i tried to use the nv tool but it keeps saying phone wont connect.
i have the drivers installed, it sees my ports for the phone, i go to connect and it does, but when i click read device it fails. Ive had no boxes checked, one box checked and both boxes for spc and fast read(i think it is) checked. No Go either way. Any suggestions for this? Then i can see if the NV Writer is a solution. Also i can use my own NV file right??? Or would that just be a corrupted file being reloaded ?? If thats the case how do i find a clean NV file for a Samsung Galaxy S3 i747 for AT&T??? Thanks again for the help brother

I would think you would need to load an NV of a different s3. I will try to load my NV here in a few and see what happens. PM me also

Ok guys i tried some settings. a guy i know tried to inject the AWS for Tmobiles band freq. and it didnt work.
SOooooooooo im thinking we might have to skip AT&T phones on metro/tmo and get a tmo phone or a AT&T phone that supports AWS band freq.

Wait....How are you getting 4g ?? it might not be LTE but da*m its faster than Edge. Could you tell me your apn, and your settings if you changed anything since you first switched to metropcs.
Like dial star, hash(number sign)twice, the 4636 and star,hash star, hash and go to device info, then screen shot, then scroll down and screen shot again where i can see "set preferred network"
also man are you sure you have the S3 I747 from AT&T??

Make sure you are checking your connection in Settings > About Device > Status > Network Type
You cant always trust what's displayed in the status bar. Especially when using a custom rom or using a device on a different network than it was intended for.

Yea man I know. I've checked everything and says edge still.
I think it's based on your radio and kernel. Brad what kernel and radio you using.?
I'm on 4.3 Rooted and stock.

Use on verizon

My s3 is unlocked and I have tried putting my verizon sim card in and setting the apn. I will get full signal with voice and data for about 30 seconds before switching to no signal. While I have signal I can make calls and a text or use data. Is verizon kicking the phone off their network or is there something else I need to change?

Might be because you're using (I assume) a gsm device on a CDMA network. I have no idea really. Might want to ask in the Verizon forums where they are familiar with that network.

Yeah I know that the att s3 is GSM vs verizon being CDMA however with their lte am card I wasn't sure. I'm not even sure which verizon forum to ask in. I have a feeling I'll get flamed if I ask in the verizon s3 forum.

You shouldn't. Just say you asked here first but was told to as there as well since they're more familiar with what will or won't work on their networks. Ask if anyone's heard of any success using the I747 there.
Whenever you have device or rom type problems, its best to ask in the devices forum. But if you are having network connectivity issues it can be wise to ask someone with knowledge of the network you're trying to use.
If they do give you a hard time, let me know and I should be able to find someone who's willing to help.
If you explain why you are asking there it shouldn't be a problem though.
