Not able to use 3G on my galaxy i9000 - Vibrant General

i gotta a question and hopefully someone can help me. i bought a samsung i9000 unlocked from the web and its working fine with T-mobile, however I m not able to use their 3G because of diferent frequencies. is there a way to fixed that either with flashing or anything at all? I wanted the galaxy with the front facing camera in it but now since the camera requires 3G i still can not use it. even if im conecting wireless when i try to make a call it checks for the prtovider and since its on EDGE and not 3G it gives me a message saying that Im out of the 3G coverage area and that I can go ahead and make a voice call instead.

unfortunately there is no way around this, it is a hardware thing not a software thing so you wont be able to get 3g on your galaxy

how do access the Internet settings such as change dns serer address
I don't see the DNS anywhere but there are a lot of options if you go to the Browser->Menu->More->Settings
Anyone else have a G1 with no internet connection?
I got mine the morning of the 22nd, and since then I've not been able to access the internet by either means of Edge or 3G. I also live in a very good 3G coverage area. Anyone else having this issue?
I called T-mobile, they escalated it up to engineering and told me they are working on it. Was told I'd more than likely get called back today, and i didn't... Seems everyone I know has no issues with the net and their new G1's.. Anyone here having this problem?
I'm liking the phone OK, but for the 349.99 and 30 bucks tax (I wasn't eligible for the upgrade)and 4 hours in line... I'd like the internet to work out of the box. .
Half tempted to get the Touch Pro, since it appears to be at a local best buy...
I had a HTC diamond touch with WM6.1 same processor pretty much a kickass phone and I can tell a big different when it comes to internet speed.I don't live in a 3G area but the G1 browser is faster than Mobile Internet Explorer and Opera.Mine started working out of the box.
If I were you I would go to your Tmo store and ask and think about the other phone....it's gonna be more expensive too.
See ya.
I did for the 22nd
the chick put the g1 data plan on the wrong line, so I got no joy till I called and had it fixed then waited 8hours for the setting to change...
but now all is well

Does anyone else's EDGE randomly go off and on? And not the no-service so no-edge thing, i mean i'll be in the same position and it will randomly disappear and reappear...other times it just doesn't connect.
another thing PLEASE HELP WITH...
i have cincinnati bell and they recently rolled out Dual-band WCDMA 1700/2100 network.
is this NOT the same as t-mobiles? i partially bought this phone because it would work with cinci bell because they were both on the 1700/2100 band, but apparently not because i can't get 3g signal...well i've seen it flash 3g before for like 1 second but then it goes away.
any suggestions? i also have mms troubles but thats another thing i'll worry about after fixing my current problems.
I'd guess you need to change the APN settings. Google "g1 att apn" and you should get plenty of instructions for AT&T. Just modify them to work with Cincinnati Bell. And yes, Cincinnati Bell is using the same 1700/2100 AWS-1 T-mo is using.
i have the correct APN - internet DOES work and has worked on all other devices using my current APN configuration.
Hm. Beats me then. Are EDGE and 3G rock solid right now with your other devices?
i hope thats it...EDGE works...most of the time. i haven't gotten G yet. i have no other device to test 3g on...except my brother's super un-smartphone nokia 3555 which displays "3g" at the top almost always...that's the only other 1700/2100 mhz phone that i know of.
hopefully this gets fixed in an update? also, should i delete all other APN's from the list besides my CBW one? and should i have a separate APN for mms and data (cause under the tmobile ones the apn type on the data is set to default and apn type under mms is mms...i copied this format...no luck either...mms still doesn't work).
EDGE and GSM is Smoothest across all HTC i have used.
and GPS is the fastest in all HTC Device may be becuase of Dedicated Antena on Body below Battery cover
I just received mine yesterday and have been using internet all day. the only problem i had was at 2am (gmt) i was dropped down to 2g. But that was a t-mobile problem, my PC broadband was dropped down to 2g also.
Both were back on 3g when i got up.
In you case it may be the phone, id phone up your operator. If your network isnt experiencing any problems then you should send your phone back.

X1i when using 3G on AT&T I cant make or receive calls???

So when I leave all the band settings to auto on the phone, it immediately connects to AT&T's 3G network and shows the "H" in the title bar it worked for a little while then calls stopped coming through, after a hard reset it works again with calls for a few hours, then it begins to fail.
If I switch the bands to GSM and manually select the frequencies (850 + 1900, according to wm) then it connects to the EDGE network, and I can make and receive calls as I please, no problems, except for the crappy network speed.
So someone help me out here please, is the phone defective, or is it not working as it should because of the lack of the 850 band? I know that AT&T works on either or but this problem has me stumped.
Other than this rather huge problem (phone that cant make calls), I absolutely love the Xperia and would hate to return and wait for another.
did you try to use the connection wizard to let the phone config itself?
after I put my iphone sim in it shows the H/3G icon on anf off all the time, while I can receive call I was unable to go online.... after someone suggested me to call att to update the imei on my account to the x1, I found that I still have to go to connection and change the setting myself b4 it can go online. you will have to remove the user name and pw in media net setting and uncheck the proxy server.
I guess my case is a little different than yours but I guess you can give it a try... good luck =)
Thanks, I actually haven't tried that since i figured it would be the same as what happens when you turn the phone on for the first time, when it autoconfigs.
if it say it detect a new sim and ask if you want to do the auto config then I guess its the same... but again I did need to change some settings inside the network config to make it work too... so I am guessing the "auto config" has some flaw in it
No problem with my X1i when I venture in a1900mhz area close to my home. I live in a small town in Ca. only 850mhz here. But in the larger Metro area around me... No Problems with calls or hspeed data access...
Stuart
Thanks for the replies, It looks like the Configuration wizard in the settings menu did the trick. It do something else that the autoconfig doesnt. The phone seems to work now just fine, although it doesnt hang on to the signal as well as my old k790a. The office I work in is an ATT dead zone and I could make calls using the K790a with only one bar, with the Xperia it either doesnt go through or drops the call.
Again this is better as it works now, just not as well as my old phone.
Also, scl_electronics, so you are saying the X1i has both 850 and 1900mhz bands? I had a feeling mine did too, but I thought it was put to rest that that wasnt the case with the X1i....
Sorry Aaron J,
i should have been more specific!! Where I live, 3G is only on 850mhz band so I don't get access..Just The edge network. When I venture about 10 mile away toward the major Metro areas..The 1900mhz band are used. So the H is displayed, but I don't have those access problems for calls or data!!
But i am waiting to see if they can crack the rom for 850mhz-3G access!!

Oh ok thats kind of makes, sense although I thought the X1i didnt have an 850 band at all, so what frequency does it work off then?
Anyways, back to my problem....I spoke too soon, it dont work on 3G switched to EDGE. I might just try getting a new sim card, mine is a Cingular one from 2005, that has been in at least 4 different phones now including the X1i.

Well out here in Ca... 850mhz gsm/edge is used ..So I quad band gsm phone is handy!!!
Stuart
Yes it is! My little problem is a little confusing though as one thing I just realized that I didnt say before is that the phone has no problem connecting to the 3G network using HSDPA. I get full bars with the H icon pretty much everywhere in my area and my data speeds are very good. So I can surf the net, download programs, watch high quality youtube videos using the app in touchflo and even send and receive texts just fine.....just no calls when on 3G. I'm hoping its just setting somewhere and not a faulty device.
I live in Raleigh NC by the way so maybe it could be a faulty tower?
Well when venture into Stockton Ca. my phone switches to 3G-HSDPA:1900MHZ Without a connection hitch....
Have you tried a soft reset......
But when all else fails Hard Reset to the Rescue!!!
Btw... in several of my ppc-wm units when restoring to OEM setting(hard reset) there has been many time the process had a problem. So something would be screwed up!! So when You don't succeed, try another hard reset!!
Good luck,
Stuart
hey i was wonder if your problem is HSDPA/HSUPA being on, i have at&t also and it worked for the first few weeks fine with it being on then all of a sudden it stopped and couldn't connect to the internet, before i had the H/Edge showing up and also my email never updated when it was set to do it every 15minutes. Now that i disable the HSDPA/HSUPA i see 3G/Edge and email update all the time on the X1i. Just wonder if that might fix it, I'm all kinda still new to all this but i had my X1i for 2 1/2 weeks now.
Hello thanks for all the suggestions, Experiaenjoy, no I haven't tried mainly because I can connect to the data network just fine and get awesome speeds with full bars pretty much everywhere, all of my data related activities and programs work just fine (aka murder my battery life ). I just cant make calls while on 3G.
I talked to a coworker today who used to be a regional manager at AT&T hee said that he saw many cases of people who were having problems where it was due to the SIM card. He said they all had the older orange Cingular card and that an update to the new blue AT&T card solved all problems. So right now I'm trying to see if I can get mine updated (I do have an older Cingular SIM). Once I get that, I will do a hard reset (3rd one also done about 20 soft resets since I 've had it-I've installed a bunch of programs and tweaks) and skip the auto config and go straight to the connection wizard.

Simultaneous Voice and Data on T-Mobile USA?

Hey there, I swear I though we could have simultaneous voice and data with the Nexus One on T-Mobile USA yet it's not working for me.
Anyone else? Let me know if it's working or not...
NOTE: don't be connected to WiFi at the time of testing. Make a phone call, then try to view google maps and move around, or go surf the internet using the browser and report back.
Thanks everyone!
are you sure you are on 3G? EDGE does not support voice and data at the same time.
Ahh, well my phone has been having the issue that a lot of people have been reporting where it flips back and fourth from 3G to EDGE, so perhaps that's why.... I'm testing it right now when knowing it's on 3G.... So it works when I have the 3G icon.
I think my problem is that the phone is locking on EDGE and not swapping to 3G when it has the option to once on a phone call... My phone seems to be swapping from EDGE to 3G just like a lot of people are saying, even when they have other phones with no issues on the same carrier at the same locations.
Thanks for that info! still having the issue of the phone seemingly not wanting to jump to a 3G cell after it jumps to EDGE.

[Q] Problems achieving a good internet speed

After few weeks of searching for the right answer in here and everywhere, I gave up,so I have to ask you guys what kind of the problem do you think I have!
So, first of all,I have the HD2 without the branding T-Mobile on the upper front, but after a soft reset I see the stick together pink logo, so I presume it is a T-Mobile device!
Then I have to say the ROM is not cooked, on Connections I have "Enable HSDPA/HSUPA" checked, on band and network, both of them are on Auto (I've play with both of them but no changes)..the 3G is enabled on Comm.Manager
My problem is I'm ALWAYS getting an Edge sign on signal strenght(South Rainbow Blvd or on the strip-for those who are living in Vegas),my internet speed is a little bit bellow bad(no matter what browser I'm using)all the programs that require a internet connection are also very slow,BUT, on mobilespeedcheck.com(or net?)I am getting something above 3G(Evdo/Hsdpa),getting sometimes speeds very close to Broadband.Maybe I should tell you that on T-Mobile data/sign coverage my home is listed as very good signal(dark red)...and my Radio is 2.10.50.26, ROM 2.13.531.1(90063).
Hoping I'll receive some advices from you guys I hope you'll all have a good day/night and thank you!
Sorry to break it to you...but you don't have a T-Mobile US device...you have an international HD2 with a T-Mobile USA stock ROM applied. You will NEVER get anything above EDGE using T-Mobile USA service with an international device, as the bands that they can use are different. The only way to get 3G in the US out of an international HD2 is to use it on AT&T.
Thank you, man!...But can you tell me why I'm getting those speeds over the mobile speed tests?....'cause that thing I don't understand...and do you know from your personal experience if AT&T internet is worth the sweat to move(like coverage, signal strenght....)
Thanks again for your time

AT&T S7 Edge signal issue

I have the S7 Edge from AT&T (SM-G935A) and I get terrible reception at work. I have to turn airplane mode on and off 3-5 times during my lunch break just to send a few texts. I also have an older unlocked Note 5 (SM-N920C) which will struggle a bit but will still send and receive every text after a few seconds (20-30) of spinning its little wheel. So the question is why would an unlocked non carrier specific phone lock onto the AT&T signal better than an AT&T phone? I've been into the AT&T store and nthey seem to have no idea. The S7 Edge works great anywhere that I have a couple bars of LTE but when it's struggling with 1 bar of LTE or just plain 4G it's not so great. Any suggestions?
That type of subtle difference in coverage can be caused by the little differences in design. Phones today mostly use the frame for the antenna, so Samsung has to make adjustments for the edge, and the Note 5 simply has more room for the antenna. I haven't pulled the edge apart, but that's my guess based on years in the industry.
The other possibility is that it's struggling to keep an LTE 'enhanced' connection for HD Voice and video calling, which of course an int'l Note doesn't have. Try turning off enhanced LTE in mobile data settings & see if it makes a difference. Or maybe try switching to the HSPA+ 'wap' apn and maybe if it isn't always looking for LTE it'll hold the connection longer
Motorola phone for u bro they have the best signal of any phone I've ever used. Also some believe the way you hold it matters. And cases may effect signal strength. Some buildings affect signal strength as well maybe try a different location.? The note gets better signal because of the size.

Thanks for the suggestions. I switched to the unlocked S7 Edge (935F) and it works even better than the Note 5 did. It makes no sense at all.

FYI, the code you show is incorrect, it should be *#*#4636#*#*. I get an invalid code error message if I use your code.
