Samsung I780 i780MSHC3 failed to connect AT&T's 3G network - General Topics

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.
http://forum.xda-developers.com/showthread.php?t=384619&highlight=i780+radio

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...

Touch Cruise, HSDPA, Tmobile, US or EU?

I recently purchased an HTC Touch Cruise from phonesource-USA without doing my homework. (What can I say, I was overwhelmed by the coolness of the phone). Before this phone, I was using an Excalibur and a Titan from HTC. I think I already know the answer to this question, but wanted to ask the home experts out there.
I absolutely love this phone, but am I screwed on 3G when T-Mobile releases it this year?
P.S. I'm located in the U.S.

T-Mobile USA Will use 1700mHz band for 3G and according to some sources it will use 2100mHz to. Witch T-Mobile say it will not have full experience of there 3G. But it will work.
And i think it will be possible to use Radio from Sony X1 witch have same Chip sets and everything except screen.
AT&T 3G
I think I may be in the same boat. I did read up on the phone before I bought it to work on At&t's 3G network. Even thought the phone operates on 1900mghz I have not been able to get it working. It always is on the Edge network.

are you saying you have not been able to get the phone to work on att's 3G network? i've read on howard forums where other owners are seeing the "H" and "3G", suggesting that others have been able to connect...
3G
That's exactly what I am saying. I have had it configured to the correct frequency for AT&T's 3G since I turned it on. The very first time I put it on 1900 MGHZ I did see a H and then a G, but I'm sure the G was for GSM.

When you say "configured to the correct frequency for att's 3G", did you manually set the Band to 1900 mHz? or do you have it set to Automatic? for all my HTC devices that support 3G, i set the Band to Automatic and it will pick up and use the att 3G/H band automatically. i only see the "H" when i'm tethered to my laptop or downloading a 1 meg + file.
att 3g
I did it manually. I figured it wouldn't work on auto. I will try the auto detect and see what happens.
3g is up
Well it says G right now, but not 3G. I know I have crappy reception here so maybe it will change. Thanks though.
yep... having good HSDPA/UMTS coverage is a must to access the network. if it says "G", you're using GPRS, "E", you're using Edge, "3G", you're using UMTS, "H" you're using HSDPA. you might check att's website to see if you have high-speed coverage in your location. every HTC 3G capable device (e.g., supports Triband HSDPA) that i've purchased has always connected to att's network with the "Auto" Band setting...

Ah this sucks. Why can't America just use the same frequencies as the rest of the world. I don't want to have to purchase another expensive phone right after purchasing this one. Looks like a Sony X1 will eventually be in my future
Thanks for the reply.
3G???
I had it on auto all day, but no little 3G icon. I know there is coverage, becuase my TYTN and even my blackjack picked it up right away. I guess I'll just keep looking..........
AT&T 3G
I am usually indicating 3G or H. I have it set to auto and it semms to be working fine for me.

I too have found you need to leave the phone set to Auto. A soft reset after you change it from manual selection to auto gets me the 3G back immediately on boot up.
ATT 3G
I have ATT 3G & H in some areas when I travel but my home area does not have 3G coverage only EDGE at the moment. It depends on ATT's coverage whether you will get 3G or H. The phone is fully capable to work with ATT.
got my Orbit 2 today, and HSDPA & UMTS are working fine (in dallas)...
using a polaris with at&t in buffalo, ny. 3g and HSPDA work fine in most areas. sometimes if i go deep within a building it will swtich to edge which is normal.
3G!

T-Mobile 3g with Samsung Epix

I have a samsung EPIX I have done a lot of looking around all over I found that the epix supports 2100ghz HSDPA. So it should use T-Mobile 3g am I correct? I can not for the life of me figure out how to get it to work am I fighting a losing battle is it not possible? Am I missing something in the setup? I have had it for a few weeks and really love it. I would appreciate any help thanks.
John
hmm normally u have to goto connections setting and turn on HSDPA and reboot the device. it should auto connect using the 3G ,(depening on fone icons H mite show instead of 3G) as far as im aware HSDPA is great if using ur fone as a modem for laptops or desktop computers,
t-mobile uk supports upto 4.2mbs depending on area.
i'll try to look into this for u but u mite need to contact samsung as T-mobile only support soo much.
also HSDPA loves to drain the battery!
I called Tmob support and they said all I have to do is pop my sim card in and if the settings are correct it will work on 3G. They did not have any other info for me on my phone. I have no problem using EDGE network so I am assuming it is just in the phone. I do know now that my account is ready for 3G thats a plus YAY! I also did not see a place in setting to turn on HSDPA. Thanks for your help it is greatly appreciated.
This is from the samsung web site it shows it supports UMTS/HSDPA (850,1900, 2100MHz). I found a service menu code to set the phone to wcdma only, but i get no service when I force it to use wcdma. Wcdma is the band for 3g am I correct? I also found a code to let me lock the exact band I want to use but I do not see 2100 I do see a 2000 but 2000 still dose not alow me to get service.Am I missing something? Am I just fighting a losing battle?
well my friend, I have been having the same question stirr in my head for weeks now, because i got this phone like a month ago and i love it. i would prefer this phone over almost anything that is out right now. What i have found out so far is that this is a losing battle. our phone (epix) does support 2100ghz but it does NOT support the also equally as important uplink frequency. (1700ghz). this is the problem. Tmobile uses 1700ghz uplink and 2100ghz downlink. and as far as ive discovered the is absolutely no way to fix this. no radio rom dowload, and no adjustment to the radio reciever/transmiter that ive found. i also am willing to do just about anything to get 3G with this phone also because its a BEAST. this phone is very quick and has a TON of amazing features but theyre really not that great if you cant get the phone to work to the best of its abilities. anyway, hope that helped a little.
yep, must have both 1700mhz and 2100mhz radio for tmob 3G! Very few ppc devices have this off the wall 1700...
that is correct, you must have both the 1700 and 2100 bands supported. Not very have the 1700 unless they are branded as tmobile. I have a tilt 2 and the Epix both running on the TMO network and neither will ever be able to use 3G.

Fuze use in Germany

Hello everyone. I recently moved to Germany from the US and had my Fuze SIM unlocked. Well today I went to a T-mobile kiosk and the rep told me that I can use the phone for regular phone service with no problems but he didn't think that the US spec Fuze would work on the Internet with their data plan? Does anyone know if this is true? Why would it not work? Does T-mobile in Germany use a different band for Internet that the US Fuze doesn't support? Any information that anyone can provide would be greatly appreciated.
Thanks,
Murnutz
http://en.wikipedia.org/wiki/GSM_frequency_bands#GSM_frequency_usage_in_Europe
for normal gsm
http://en.wikipedia.org/wiki/UMTS_frequency_bands
for umts (3g)
and of cause if you got a non gsm device like a simcardless cmda phone == nowhere
itll work fine for phone and data up to 2g. if you want 3g check if it can do international bands or just us ones.

Unlocked Us Cellular phone to WU but wont work on At&t network

I unlocked my us cellular phone and now when i try to use it with ar&t i cant use the internet while im on the phone or find an at&t rom so i can use programs at&t offer can anyone help and i dont see a G next to to atenna just an E
Us cellular
So is it possible then to use the touch pro 2 from us cellular on a gsm network?
Thanks
yea it is but you wont be able to use a lot of features i believe ive been looking around for answers and asking ppl but no one seems to have anything to say
interesting. so what are the features i wont be able to use??
1) The US Cellular TP2 likely only supports the Euro 3G frequencies. As a result you will only get EDGE (indicated by the E) when on GSM in the US, not 3G.
2) If you want to use the Internet on ATT, you need to configure the ATT data settings (and of course pay for data) the same as you would with any unlocked/unbranded GSM phone. The settings can be found on the ATT site.
3) The US Cellular phone can run any WinMo programs that you install on it. You don't need a specific ROM.
To claim you "won't be able to use a lot of features" is incorrect.
???
I am living in Jamaica so can the us cellular touch pro 2 be used here on a Gsm network with/ without being unlocked? thanks
yes it will make call and answer but internet you need to set it up
in costa rica it works but internet does not work
wow. i have been dealing with a very similar issue.
i am using a US Cellular TP2 on AT&T, Sim unlocked and security unlocked with the radio provided by Olinex. radio version2.32.00WU. see signature.
i am using an Energy CDMA rom, and i have internet, but i have been searching for some sort of settings to get 3G. as of now i am stuck with the E, or edge data connection. i have changed all of my settings to match those of MEdia Net, but still no 3G.
Anyone have any info or suggestions?

[Q] Touch Pro on T-Mobile 4G

I've got the Touch Pro (T7272-unlocked not t-Mobile branded) and am a T-Mobile customer.
Does anyone know if this device works on the T-Mobile 4G network?
If so, what setting, if any, need to be changed?
The package says the phone supports HSPA network, but T-Mobile's is HSPA+.
The phone will work, but I believe only on EDGE. The radio bands are wrong to get 3G or I guess 4G. There's nothing you can do about it.
Thanks for your reply.
I've used it for years with EDGE, which is brutally sloooooow.
I was wondering what spec determines if a phone will work on T-Mobile 4G network?
that is correct. att's 3/4g opperates arround 1800hmz while tmobiles 3/4g opperates around 1700mhz to no matter what you do (outside of switching carriers) there is no way you can opperate outside of edge

Rastin,
Thanks for your reply.
Is there any possibility that a software solution could change the Band Frequency?
Unfortunately it`s imposible.
