HI,
I just got a samsung I780 and flashed the i780MSHC3 rom, today i got a att pda plan. However, I can't use i780 to connect att's 3g network, always in gsm/gprs....... (using in LA, 3G definitely covered)
Is there anybody having the same problem, or could somebody give me some advice (already called att, but not worked out)
also,
Gyngabread Man could you help me to change my plan to the $30 PDA connect with isp support?
Thank you
Please help...
my date plan is PDA PERSONAL CV TE
I screwed up...
please help
how to make i780 tri-band 3g????
Anybody helps????
whether there is a way make i780 works on att's 3g?
Thanks....................
What phone rom are you using ?
If is an old one, try with the italian one.

my phone radio rom is:
XIHA7 the Italy rom...
I just wonder whether i780 is capitiable for att's 3g network, if now whether there is a "solution"?
is there anybody else using i780 in U.S. on ATT 3g network?
Thanks.....
The phone does not have 850/1900, only 2100. How do you plan on using AT&T's 3G network without 1900?
Changing the ROM will not give your phone the ability to now utilize AT&T's 3G network.
The weird thing is it won't even connect edge..........
but when insert t-mobile(us)'s card... it at least connected to edge....
and when i "roaming", i can connect to edge network, but with att, without roam, can only connect to gprs........
dats so sucks...
Just whether why some rom will make the i780 has tri-band 3g function

Sorry to revive an old thread...I can't connect to AT&T's 3G either (I live in Chicago). The band selection on my phone, though, is
1)900/1800
2)1900
3)WCDMA (phone doesn't connect to anything with this selected)
4)Automatic
PDA ROM is DXHE1
Phone ROM is PUHE1
Am I an idiot for buying this phone (I would need 850 instead of 900 on this bad boy?) or am I just not using the right settings?
same problems here...
Unless I'm mistaken it's a hardware issue, no amount of ram flashing will get past the the fact that your phone will not broadcast on the right band...
Ok guys Here is my problem
I live abroad and I have a Verizon Galaxy S3 with unlocked SIM capability so I'm using it as a GSM phone. The problem is that my GSM network provider does not have a 3G network, however, there is this other mobile network company that does offer a 3G network but it operates on CDMA. So I flashed my phone using DFS to the CDMA network and I managed to get the phone work for both calls and Data. But now since I usually use my GSM number I have to switch back and forth between GSM and CDMA whenever I want to use data and that is pretty inconvenient, in addition, whenever I use 3G I loose my GSM connection.
So what I was thinking is whether I can activate both my GSM network and the 3G connection from the CDMA network at the same time so that I can surf the web with 3G speed and make calls using my GSM number at the same time.
To be honest with you I've been trying to get that done with no hope, I've tried all the modes the "Phone info" app with no luck, so I'm here now asking for your help.
come on guys
I can't believe no one here does not have an answer
Hello,
I am having issues with my samsung galaxy s3 i747m. This is a canadian model phone (Rogers). I am traveling so I rooted my phone and also unlocked the network. When I was in India, I was only getting 2G connection when I selected GSM/HSPA (auto) in mobile networks and was unable to connect to 3G. If I connect to HSPA only from mobile networks. I lose all my connections. I don't even receive network also. Right now I am in middle east and I am facing the same problem.
My phone has GSM, HSPA and LTE options to choose from mobile networks in settings.
Just wanted to let you know that I called the network carrier and they informed me that they have activated 3G services. It still didn't help. I tried different network sim and I am still getting 2G connection.
I changed the APN settings which is suggested by the network carrier and still I can only get 2G connection and unable to connect to 3G connection.
Some information about my phone:
Model number: SGH-i747M
Android Version: 4.4.2
Baseband version: i747MVLUFOB1
Please help me to solve this issue as 2G connection is extremely slow. I will really appreciate it.
Thanks
Hi there,
Here is few discussions about this issue:

[Q] I747M Can't get 3G/LTE data after IMEI loss / restore

Good luck
Hi all, has anyone here tried or been successful in getting the data or lte over voice calls with Verizon's S6 using Tmobile? I have Tmobile and trying to use my gf's unlocked Verizon Galaxy S6. Almost everything works fine except that while on voice call, the signal drops to 1x and I can not simultaneously use data or receive mms. Are there any fixes for this? Any help would be appreciated as she is planning to switch from Verizon to Tmobile and I would love to just reuse the phone on Tmobile.
PS: Sorry not sure if this should be in a carrier specific thread. If so, not sure which one to choose since it sort of dual carrier concern

Try going to Settings > Mobile Networks > Network Mode and change it to LTE / GSM / UMTS and see if that helps.
Is there anyway to enable UMTS 3G on this version of phone. I have used the hidden LG app and selected auto select GSM/WCMDA/LTE but I cannot get any 3G service. All I get is 4G/4GLTE or EDGE and nothing else.
2G service will be stopping soon here and I won't be able to use the phone when in EDGE mode when that happens.
I am on Vodafone in AU and live in poor service 4G area but good service 3G when I used my old Note3. I have also tried a Telstra 4G SIM and the same happens.
Looking at spec for this phone it is radio supported for 2G/3G and 4G but I suspect AT&T may have locked out 3G service.
I cannot find a non AT&T ROM anywhere so I suspect I am stuck with AT&T for the moment which I suspect this may fix the issue. But any help would be appreciated.

Strange, because using the same app I'm able to change the network mode from 2G to 3G with ease. And it works well.
Phone is OK
OK the AT&T V10 has no 900Mhz support but has 850Mhz support and 2100Mhz support
After many contacts with Vodafone AU, I found someone that knows their stuff. They tell me coastal areas have 2100Mhz and inland where I am is 900Mhz, so problem not solved but understood. But if I have a Telstra AU SIM they support 850Mhz which this model has.
