[Q] galaxy i747 no s3 siganl - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

i bought a second hand galaxy s3 AT&T i747, and now I'm using it out of the US ,
i have no 3G connection! my Carrier 3G frequency is 850 and 2100 gsm,
actually, sometimes i have 3G for a few seconds and than it disappear,
i had CM10 , and than changed to another ROM, didn't help, changed to AT&T ROM stock, permanent unlocked the phone using the IMEI,
nothing helped!
i was speaking with my carrier setting all the configuration , didn't help.
i really don't know what to do, what could be the solution?
thanks!

T-Mobile GS3 HSPA bands are HSDPA 850 / 1700 / 1900 / 2100
Orange from DR uses the 900mhz band... so no 3g for you... there's one company from PuertoRico(us) named Claro, they use the international versions on all of theirs devices, it is the only "U.S" carrier that has phone that work on the Orange DR 3G network... also the iphone's use that band...(only the GSM iphone).
Yeah I remember that they used the international version of the s2 for a reason. Couldn't find the frequencies used but you might want to check with viva as well as claro
You must be mistaking orange of another region that uses the same T-Mobile band

Same situation and same problem
The reasoning for this is because of the frequencies that your phones are capable of. The wind home network runs off 1700 mhz and 2100 mhz frequencies and your model of gs3 does not support them. The wind away network is provided through rogers so that is why you are able to connect to away.
hope this helps

I have note2, i317m from rogers. To enable AWS, I've tried flashing .qcn file and also I tried overwriting NV using QXDM. Yet, I only get to see "WIND AWAY". When I tried inserting foreign SIM, and it did display Rogers, Telus, BMS(whatever this is..)
*please ignore*
AT&T guys have tried to make their I747 models work this way with very limited success. I doubt anyone is still working on it tbh.

Sorry to awaken an old thread, but did any of you fix your problem? I'm encountering the same issue for no reason.
Had my OnePlus One for 2 years on WIND, then went to travel Europe. Worked fine roaming on cell networks there. When I got back to Canada, I was able to connect to WIND (sent a text, made a call, and used some data) for a few hours in Toronto and Vancouver. Since then (about a month) I have been unable to connect to anything but the AWAY network, on which I can't even text, call or use data...
WIND gave me a new SIM and checked my account for any problems. I tried my mom's Virgin Mobile SIM, but my OPO wasn't able to connect to that network at all (for some reason, with her SIM in my OPO, WIND still showed up in the networks with a lock icon...) And just today, I completely wiped my phone, total data and system format. Installed a new ROM, new Kernel, and flashed a couple different modems. Nothing. At. All. Absolutely madening.
Thanks in advance for any responses!

If you are looking to control whether to use 2g, 4g, or 4glte:
http://forum.xda-developers.com/showthread.php?t=2116346
You need to remove the restriction with the *#197328640# number and submenus,
then change the radio under the *#2263# number and its submenus.

Hi,
I bought a phone in the US thinking its samsung s3 i9300 but discovered its s3 i747. I'm using the phone in Kenya but it cannot connect to WCDMA, only connects to GSM mode so internet access is very slow!! Any help??
Your carrier probably does not use the same frequencies supported by the phone.

Hi,
I'm using the phonebfor voice calls and texts. I've also checked the frequencies and my carrier uses 2100 for 3g which the phone supports!! The phone status says modified and displays model as i9300 but download mode displays model as i747.
Any further advice??
Oh boy....another Franken-Phone! These things are getting too common. Wish I knew where they were coming from....
Install Terminal Emulator from the store. Open and enter this:
getprop ro.bootloader
Tell me what this returns. Also, what is your current baseband?

These are the frequencies for the sgh-i747/m: 2G - GSM 850 / 900 / 1800 / 1900, 3G - HSDPA 850 / 1900 / 2100, and 4G - LTE 700 MHz Class 17 / 2100
Does your cell carrier support the 3G frequencies?
Yes it supports

Yes it supports,,, GSM 900/1800, 3G 900/2100
For 3g, it doesn't look like the i747m supports the right frequencies.

So u wanna tell me it wont support 3g only 2g
Looks like 3g is not supported because the s3 does 850/1900/2100 and you need 900/2100. The s3 is missing the 900.
The international s3 (gt-i9300) looks like it will give you 3g: http://www.gsmarena.com/samsung_i9300_galaxy_s_iii-4238.php
both the i747 and i747m support 3G in africa. I also came across the "refurbished" ones that have a i9300 sticker at the back but in reality are i747 and i747m.
They are both fixable issues (working on 2G only). Needs flashing and then repair.
Contact me by pm if interested
Same problem here
I ran into the same problem!! What's the fix? I opened the phone to see the model number on the motherboard. It is Sghi747. But the sticker under the battery shows I have GT-I9300.
I am not able to connect to 3G. Only 2G.

Find someone who fixes phones locally, and ask them to repair NVM. And also to flash it with the correct flash file
Your suggestion did work. I appreciate your quick replies and kindness. Be blessed. You saved my Samsung Galaxy S3. It now shows 4G icon , typical of At&t S3 variant. I am enjoying the high speed Internet. Thanks again.

It's a code which only represents the numbers you hit on each menu. It's the numbers from the menus written together. You hit 1 on the first menu, 1 on the second menu...up to hit 5 on the last menu. 11865 is just written as a code for abbreviation.

Neither phone has the radios to get 3G/LTE on AT&T
I have a similar problem.. I'm on fido in Canada and I cant get 3g or 4g connection. Should I give up, or is there something I can do? I also tried changing the build.prop line to US and Canada, still no luck.
Does anybody is this phone works with Verizon???

Help needed: trying to mod my notification bar

I have a t889v running rooted stock 4.4.2 build #kot49h t889vvludnh2, which is the newest build for my phone, i'm trying to mod the battery percentage, i want it to be larger in size so i can see it better. I have tried various mods on the exposed installer i.e. wanam etc. none seem to work, so i would like to use root explorer and change the setting in build prop, the problem is i don't know where to look. if anyone knows where i need to go and what lines to adjust it would be much appreciated. thanks in advance

Do you happen to know what is new with the t889vvludnh2 ROM? I can't find any information anywhere on this update. My assumption was that LTE was enabled. But I am not sure.

i don't see much deference between this and the last rom. I don't see LTE anywhere in the network selection it's still gsm or wcdma
edit: just went into service mode and there is awhole bunch 0f LTE bands, so it seems we have LTE now. For service mode type *#2263# into the dialer and you should see a screen come up with all the band selection. i'm on wind so we do not have LTE service so there is no way to test if LTE works.

I have a windmobile T889v unlocked as well. I am currently in the states and I tried a T-Mobile sim card and did not get LTE. Only 3G. Maybe the LTE bands enabled on our phones are only for the videotron LTE bands?
Hopefully, someone on videotron can chime in.
I will try to get hold of ATT sim card to try.

Which APN did you use? Which part of the US were you in? Not all areas are covered by LTE service.
I am in LA.
It was the APN that was pre-programmed into the T-Mobile sim card. I didn't modify anything. My buddies Nexus 5 was getting LTE and he didn't program any APNs either.
While at the same location when I swapped it in my T889V I only saw 3G (in settings > about I saw HSPA and HSPA+). But def not LTE.

I got a hold of an ATT sim card with LTE service, and only got 3G speeds. Tested the speed on the T889v and an LTE enabled phone with the speed test app. So on T889v def 3G(HSPA) speeds, while on the LTE device LTE like speeds.
Anyone know which LTE band videotron enabled? I thought it was Band 4 (AWS band).
The only other thing I can think of is that the I am using the Windmobile firmware update for T889V and perhaps the version for Videotron is different even though the baseband is the same version.
I had been assuming that Videotron, WIndmobile and Mobilicity were all using the same firmware since the baseband is exactly the same.
Anyone with Videotron T889V with stock baseband upgrade getting LTE speeds?
