I am having a problem connecting to my 3G (HSDPA) with my Vibrant. My phone company is using 850 and 1900 (Bell Mobility). I have been at this problem for days now and am running out of places to look so I thought I would write down a list of what I have tried and see if anyone out there can suggest other things to check/fix. The first problem is that I am not sure when I lost my 3g as I was using WiFi as default in my home while rooting with the SuperOneClick. After rooting I installed the voodoo lagfix with a little bit of trouble so that may be where the problem lies. However, since then this is what I have done....
-Factory reset and wipe cache (didn't fix problem)
-Check APN Settings
APN - pda.bell.ca
Proxy - web.wireless.bell.ca
Port - 80
MMSC - h t t p : / / m m s . b e l l . c a / m m s / w a p e n c (spaced only because I cant post links yet)
MMS Port - 80
MCC 302
MNC 602
APN Type - Internet + mms
All others set to none or blank
-Check Flight Mode (disabled)
-Check Data Network Mode (on long power button press) (Enabled)
-Thought to try other roms, installed Darky's Ressurection 9.2, still no 3G
-Installed seeArms v0.4 with JL2 modem as that was what mine was stock. No 3g
-Entered *#0011* in Dialer to access Service mode

I dont know what other pertainent information would be needed but if your willing to help and need other info I will gladly look it up. Thanks in advance!
are you sure that you have a 3G coverage in your are?

I am sure. I live in an urban area and have had no problems with nexus one before the vibrant.
I actually resolved the problem. I went into the bell mobility store and they put in a new sim card and refreshed my data package and everything was fine. No idea why this happened but it's all good now.
Thanks for your interest in helping!
Did you ever have 3g on your vibrant?? If you are not on the tmo network you will not get 3g only edge. Just like you can't use an unlocked iphone on tmo with 3g. Just like any phone really. Except you can use tmo vibrant on ATT with 3g. But can't use the ATT captivate on tmo 3g.

I did have 3g for the first day I had my Vibrant until I started modding it. Like I mentioned though, 3g has been restored after a new SIM card and a refresh to my data package from Bell Mobility.
I will say though, that the 3g service I am getting is by far superior to what I had on my Nexus one with any radio I tried using. I am working in a very remote location in northern Alberta now and still get 3g
Now if only we had a stable and complete version of CM7!
Hello, I have a AT&T HTC Inspire 4g.
I don`t live in the States, and my problem with that is the fact that in my country the 3g network runs at 2100, and the phone isn`t supporting it.
I read that my operator runs 2g on 900, and also checked that the phone supports it, but there is no option in the menu to change from 3g/4g to 2g
Can you tell me how and if I can do it
Thank you in advance
SOLVED!
Fist write this in "Phone"
*#*#4636#*#*
Then change->
Phone information > Set preferred network type > to GSM only
Then make new access point names - name: simple, apn: simple
Hi All,
I just got the international Z5c, model E5823, which supports both tmo us LTE bands in my area (bands 1 and 12). When I have preferred network type set to 3G, I get more bars and have data connectivity. When I switch it to 4G, the bars go down to 1 or 2, and I get no data.
I did a logcat while switching from 3G to 4G and noticed that while switching, the icon switches between H+ and H, then eventually drops out. I'm still trying to see if there is anything useful in the logcat, but the one thing I noticed that seemed interesting was
Code:
D/StatusBar.NetworkController( 2598): updateIconSet, voice network type is: 13/LTE, data network type is: 13/LTE
To me, this looks like I might be seeing issues with some failed attempt to use voice over lte (as this phone supports it).
Regardless, does anyone know how I can disable voice over LTE? There was an option in the phone menu on the Z3 supposedly that would let you toggle, but I don't see it anywhere on this.
I'm going to be cross posting this in the sony forums as well, so if I hear back I'll post here.
Fixed it. I turned it onto 3g and selected "Internet settings" from the networking menu, which seems to have downloaded some configuration stuff from my carrier. After switching back to 4g I have fully working data.
I love this phone....there, I said it. But it's driving me crazy.
I bought it from a Chinese retailer, who shipped it with X821 firmware, but the box states that it's an X820. I doubt there is any difference in the hardware.
I would have left everything as it was, but I can't seem to make phone calls (don't have a data plan yet...yeah, I know....) with anything other than 2G, and that is about to go extinct. When I set it to WCDMA, it shows a UMTS connection, with no carrier designation, but the tower is the same one I connect to with 2G. The phone does sometimes show an AT&T 3G connection in the status bar, but I can't make calls, even though I have full signal. When I place the same SIM in my old HTC Inspire, the same monitoring app shows "UMTS - AT&T HSDPA+" and works just fine.
I'm at my wits end. I have rooted, installed TeamSpain recovery, replaced the firmware with the X829 and even tinkered with the frequency configurations through DFS Studio (which did a lot of complaining, and I'm still not sure if the changes stuck 100%). I also played with APN settings and tried the SIM in different slots, both alone, and with another SIM. And after all of that, still no progress in getting this phone to use a 3G or 4G connection to make calls. If I don't set it to "GSM only", no phone calls in or out. I'm essentially right under a tower, so signal shouldn't be an issue.
If anyone is using the same provider in the US, and is not having these kinds of issues, I'd really appreciate hearing what firmware you are using, and/or what you did to get things working.
I am using it on x820 with official stock 0.17s firmware, and did a dirty flash to cuoco92's 17s firmware. Everything works including HD voice calls, and full LTE.

I tried this, as well as the Remix ROM. In fact, I think I've tried just about everything, without success. At one point, I had one of the apps indicating a 4G connection, but the phone diagnostics showed GSM (2G). Even the apps aren't all sure what to make of what's going on with the connections reported by this phone.
Currently on the cuoco92 v35 ROM. When WCDMA is enabled, I see simply a good UMTS connection , sans carrier name, in the "Network Cell Info Lite" app, and no ability to make calls. I also often (but not always) see the "AT&T 3G" sign. 4G or LTE never shows at all, even though the diagnostics show that the phone is communicating with an LTE transmitter, when preferred network is set to "unknown". It won't even let me set things like "LTE only".
Any chance you could set your phone to WCDMA and see what the "Network Cell Info Lite" app shows you? Anyone else with this phone on AT&T?
BTW, I am now using a data plan, which I thought might make a difference. It doesn't. EDGE data only for me . New SIM card is on the way, but my hopes aren't high.
Is it possible for a Chinese seller to have borked the phone so thoroughly with their x821 ROM (it's an x820 marked phone), that it keeps any subsequent radios from flashing properly? I don't know how/why it would work for some and not others.
Starting to really dislike this "phone"......it's more of tablet at this point.
Thanks.
I think APN is not set for AT&T
try this:
"Main steps
To use data services on our network with a non-AT&T device, you may need to program the data settings. The sections below provide the correct settings and steps for programming based on your device type and operating system.
.
Access the Settings menu.

Thanks, but I wish it were so simple. I have tried this, and other APN settings. None work to get this phone to be usable on anything other than 2G.
I just received and activated the replacement SIM. Still no improvement. While typing this, I have Network Cell Info Lite app running, and with the Set Preferred Network Type showing "Unknown" in the phone's diagnostic screen, It will switch randomly between "EDGE AT&T" (which works fine) and "UMTS -" (which is useless). Both have strong signals. For a split second before it switched to "UMTS-", the app showed "GPRS AT&T", but only for a split second before it kicks over to "UMTS-".
I wish someone using this "phone" on AT&T in the US, would run this app to compare notes. It may be that that the phone works fine on a full implementation of LTE (i.e. in locations where AT&T have already deprecated 2G) but not in other areas. Still, that doesn't seem to explain why this phone seems unable to register on the same 3G network, used easily by my other phone, with the very same APN settings and SIM.
You would have to call att and check if they turned our phone on to use lte. If your phone is not "registered" as an LTE capable phone it wouldn't be able to pick it up. This phone has all the bands needed for AT&T because I am using it now. All LTE work straight out the box, and i'm on the latest 19s cn rom

I'm a bit confused. Is this what you did to achieve proper function of this device? I.e. calling AT&T and getting them to do this for you? My conversation with their tech person didn't seem to bear fruit in this regard.
Also, which slot do you have the SIM card in? I've used the stock 17s and now on cuoco92 v35 ROM. There definitely seems to be a difference in how the network settings behave, based on the location of the SIM. At one point, after selecting BAND 6 (when it would let me), the phone showed a constant "AT&T 3G" connection, but it was useless. No calls and no data.
I just purchased the Mate 10 PRO (US version). I previously owned LGv20 also on AT&T network and simply moved the SIM to the new phone. At first there was no data at all so I called AT&T and gave them the device IMEI. Still didn't work. Called AT&T again and they had to "send a 4G signal" from the tower to my phone. Oddly, next to the signal bars it shows 4G so I was excited. However, when I went into the settings to "enable 4G" it will automatically turn to the "off" position. It seems like my phone is stuck on 3G (WDCDMA). When I am in settings and choose the "preferred network" to "LTE/WCDMA/GSM auto" it will automatically change to "WCDMA/GSM Auto". Under the "advanced" setting the "carrier aggregation" and "LTE high-speed mode" is on. APN settings are correct. Under "status", it shows network as "AT&T" and mobile network type as "4G", service state "in service".
Phone is on build number BLA-A09 8.0.0..119 (C567).
I did a speed test and my download rate on data is 2-3mb/sec.
Has anyone else had problems connecting to 4G on AT&T ? Any ideas how to fix this?
Brand new out of the box, I would promptly return and buy a new one.
