I have an unlocked mda, but i want to use the 3g network. Is there anything i can do to get it to work? Or just get a (at&t) phone?
Basically, there should be no problem if you are using a 3G network based on GSM baseband. However if the 3G network is not GSM based, you have no way to get it work unless using another phone.
I have a question.If AT&T and T-Mobile both use 1900 for 3g then why can't we get 3g on att?
Tmo US & Att use diff bands for 3G access but same for 2G.You will need to buy a Rogers Dream to use 3G on Att. A Tmobile branded phone is unable to use 3G from another carrier.
att 3g
does it have to be a rogers or a basic unbranded will work
The rom and radio
How does changing the rom affect the radio?Does the rom determine the freq the cell accesses?
the rom effects nothing. the radio effects nothing. the hardware determines what frequencies can be used by the device.
the only way the rom effects anything is if the APNs arent set correctly, but thats a simple fix. however, you cant change the APNs or ANY software on the phone to allow a TMO G1 to use 3G on ATT. Cant happen. If you really want a G1 on ATT, buy a Rogers G1 off ebay.
Trying to turn off 3G data so I can just get EDGE on my AT&T tab. Can't find any setting for it...
(the scenerio is that with Tmo DayPass, after 30MB they throttle down to 70kbps, but apparently if you turn off 3G, then you get EDGE instead (200kbps)).
I'm guess the option has been removed from the AT&T tab... as apparently its in other GSM ROMs...
Settings, wireless settings, mobile networks, network mode, gsm only.
But if you are using a T-Mobile day pass and t-mobile sim card, with an at&t tab, the best speed you can get is EDGE anyway.
This doesn't make sense -

1) my AT&T tab doesn't have the settings that you cite, which others have also said is the way to turn off 3G. Specifically, Settings>WirelessAndNetwork>MobileNetworks does NOT have NetworkMode, only UsePacketData, DataRoaming, AccessPointNames and NetworkOperators. Hence my speculation that maybe AT&T took away this option to shut off 3G... is there another way to do it?
2) Tmo DayPass, after 30MB, I get throttled down to GPRS, not EDGE, and get about 30-70kbps. I would *like* to get at least EDGE, which would be about 200kbps.
I put my t-mobile sim in an at&t tab, and I have the network mode, so I don't know why your network menu is missing the mode.
Crazy suggestion - buy an at&t data plan. It's cheaper than the t-mobile day pass. $25 for 2gb. It's what I use. The sim came with the tab.
Honestly, I don't see what turning off 3g can do to improve speed.

People report that when you turn off 3G, devices revert to EDGE. The idea is that when you exceed the Tmo softcap, Tmo throttles the 3G speed down to about 70kbps, BUT its still running 3G even though its speeds is that of GPRS. By disabling 3G, you go back to EDGE, which is 3X the GPRS speeds in throttle mode.
The AT&T plan is cheaper IFF you need data for most of a month. But at least for now, I only am playing a day at a time. Mostly I'm on WiFi, which is most every where I need it to be.
That's interesting that you see Network mode on your AT&T tab and I don't...hmmm... are we running different ROMs? My About says:
SGH-I987
Firmware 2.2
Baseband I987UCJK1
Kernel 2.6.32.9
Build FROYO.UCJK1
Yes, I am gingerbread. But I had the same menu with froyo.
I like the JK3 modem in my at&t tab, and in my experiment with the t-mobile sim, I got pretty good speed, for EDGE, anyways. At the top of the development section there is a modem stickie, for the JK3 modem. Use odin3.
You are smart to get the at&t version of the tab. You will love it with the voice and 3g/h, if you get the at&t sim. They sell one small data plan for $15 for a gig.
Edit: not sure if this is a switching problem or the way the phone is designed, but sort of figured it out...seems that the Exhibit 4G will auto fallback to UMTS when no HSDPA link is active. Just ran some speed tests and it did in fact hold HSDPA speeds, when done it fell back to UMTS. My GS3 doesn't do this...if I have 4G/ LTE available, it stays with it. Hence the confusion.
I recently purchased a new unlocked Exhibit 4G, have been testing the various roms here...many thanks to the devs...great work! Currently trying AOIP...nice!
My primary usage is on the TMO network, at my RV site on weekends. Unfortunately, 2G is the best I can get in my location, regardless of carrier.
I live in Canada the rest of the time, on Rogers with a GS3.
I was testing out the Exhibit 4G with my Rogers sim, LTE APN's were set up ok, voice & messaging are fine, but data is wonky...I will get the 'H' (aka 4G) icon for a few seconds at a time, but for some reason I keep falling back to 3G speeds. This cycle continues over and over. AFAIK, this phone should support Rogers HPSA+ frequencies (aside from their new 2600), shouldn't it?
So I'm wondering if this is due to an incompatibility with the phone on Rogers, or needing a different baseband, or could the phone's h/w be screwy? This has been happening with all roms I have tried (AOIP, Baked, Slim).
Appreciate any insight.
I cannot get LTE at all on my vs980, using CloudyStock 2.6 and cannot get T - Mobile to receive LTE. On 24A band.
Fiddled with all the GSM settings and the fastest speed im getting is 4/0.3 contrary to a similar phone getting 50/28 so its not reception
Anyone have this problem? THanks in advance
I am switching from Verizon to T-Mobile this week so I'd like to know if your able yo get this to work. I don't have a T-Mobile sim yet so I can't test but from what I've read you just need to adjust your APN setting for T-Mobile. Have you tried this yet?
