AT&T 3G data network on the T-Mobile G2

Hello everyone, this is my first thread so please be gentle!
I currently have a G1, and hope to put it to rest very soon, and get the new G2!
(staying true to the "G")
I use an AT&T sim card on my current G1.
I have been lurking (for quite some time now) on these forums trying to find an answer to using the AT&T Sim Card on the G2. I have yet to find my answer through searching.
The capabilities I'm looking for to use on a G2 with an AT&T sim card include:
at least 3G network data speeds
normal use of calling
(I live in the US, and I don't know if that allows me to have 3G instead of EDGE)
Some things I have found:
In one other forum it said the AT&T would work on the G2, however it would only work on the EDGE network. (which I believe is 2G? please clarify if you can)
"
TMO's 3G network runs on the 1700Mhz spectrum.
AT&T's 3G network runs on the 850 and 1900Mhz spectrum.
The G2 is incapable of operating on AT&T's 3G network but will work just fine on the EDGE network.
"
the "[Guide] Subsidy Unlock, SuperCID, and Radio S-OFF" presents a sim unlock, so would that mean I could use the 3G data networks on AT&T? and have local calling? or is that something else?
Thanks in advance!

The Subsidy Unlock would allow the use of the AT&T sim card. I'm quite sure you wouldn't get the 3G+ speeds. Edge only, just like the G1.

T-Mobile HTC G2. rage+gfree worked great. Tested on both TMO & AT&T Networks and everything worked with no problems. Went from getting no radio signal due to Code unlock method, to getting any network I choose.

That was from someone in the sim unlock thread. Not sure if any network chosen means 2g/3g but I would think 3g would be supported.

It isn't just your phone, I don't think any phones ever come out with the correct bands for ATT and Tmobile...Even the N1 which is supposed to be a world phone was only EDGE on ATT

The T-Mobile G2 will not work with 3G on AT&T (as you stated in the original post, the 3G or UMTS bands are different). It will instead use the regular GSM bands for 2G data.
If you want a Desire Z that works on AT&T's 3G, you have to get the NAM version offered by Bell Canada (check out the Desire Z forums). Once unlocked, it'll work fine on AT&T's 3G network.

Actually, Nokia's latest smartphones are pentaband - they can use 3G on AT&T, T-Mobile, and the European networks. This includes the C7, N8, and upcoming E7.
I have the N8 right now and have used it on both AT&T and T-Mobile with 3G.

Ah this was extremely helpful!
Thank you all for the help as well.

This is where I got my Desire Z: http://negrielectronics.com/htc-desire-z-850-1900-3g-unlocked.html
I didn't believe it and was scared that I'd open the box and see the wrong bands but sure enough, it works. Brandon from pocketnow.com did a review on it as well with that specific device.
Let me know if you need/want screenshots for proof

Ah proof/screenshots for AT&T 3G working on the HTC Desire Z? Sure that would be great! Thanks for your time!
I'm probably going to go for this phone then!

Here are a couple for you! Let me know if you want more. I tried taking pictures with another phone (I still have my N1) but it wasn't very clear.

Check the baseband in my screenshot against the basebands in the dev section if you'd like. They should match up

Ah! Beautiful!!
Thank you so much I think that's proof enough! haha.
I'll definitely be getting this phone!
I searched forever for an answer, and this surely is the answer.
Finally will be putting my G1 to rest haha

You betcha! For what it's worth, this is how I found out.

I have a NAM Unbranded/Unlocked version that I am using on AT&T as well. I purchased mine on Ebay, it was a little cheaper than buying it through Negri (which also didn't have any when I purchased mine)
Definitely works on 3G AND can be used with a 'dumb-phone' data plan ($10/month unlimited) =D

How do you get the $10/mo data plan? I don't have that option!

Yeah I know this is going a little off topic (sorry mods)
but I think he's talking about individual unlimited data plan for "basic" phones?
I kept trying to pester AT&T about it.
So is it true you don't need the DataPro plan in order to acheive 3G data networks with smartphones?
And you can use the "basic" unlimited data plan for cheaper for the same 3G networks?
The AT&T reps kept saying otherwise.
Thanks again all for the replies!

I have a family plan with an Iphone line (sister). My phone (originally a BB when contract signed) and 2 Dumbphones (parents)
What I did was, take my SIM card, and put it into one of the dumbphones. Went into ATT and had them add unlimited Data to that line at the $10 option. (And cancel the BB services since I wasn't using the phone anymore - told them I sold it on CL) Went home and returned the SIM into my BB and I was all set to go with unlimited Data. The only thing that didn't work with the BB was the push Email services...
If you go to your online account with ATT it will show you an image of the device you are using with service and although it showed my device as a BB at the time, (after returning the SIM to the BB) the $10 plan continued to work without any hitches.
Now that I have a phone that is unbranded with an IMEI # that ATT doesn't recognize, they don't have an image for my phone, so they have no way to detect that I am using a smartphone.
I have used the $10 plan with many devices: BB, Touch Pro, Nokia E71, etc and have never had any problems.

Yes that is the plan that I am referring to and yes the reps are full of crap. ATT wants to charge you more for having a 'smartphone' even though you use the exact same data, frequencies, and service as other users. There are many ways around this, but going into an AT&T store and trying to 'reason' with them is not one. I suggest the method I used with a dumbphone. Alternatively, you can do the same process online through account manager without having to deal with a live person.

Side question here. I'm thinking about giving the G2 to a friend on AT&T. The thing is that he doesn't want to pay for a data plan. Will AT&T force a data plan onto the line? Also un checking data enabled, will that stop all data over the cellular network so he doesnt get charged at all?

I don't think they can force a data plan as the phone is not being subsidized by ATT because of a contract.
In theory disabling data will stop all data but in reality he will probably still use a bit of it. Search the forums as I remember another user having the issue of zero data use.

I finally did the whole unlock, super CID thing using gfree and adb.
Just want to make that no one has found a way to get 3G speeds on the G2?
Or is EDGE my only choice? I understand the whole band thing as well.

No. From what I've gathered on the g2 being on at&t, its impossible as the radio hardware is different and will not pick up the 3g bands. Flashing a different radio to match up the bands won't work, either (it will possibly brick your phone, actually.)
Go with the NAM Desire Z from bell canada. Its your best bet.

[Q] Tmobile customer traveling to Canada

Hey everyone- not new to the community but i need some help in figuring out what exactly needs to be done for me to get service in Toronto.
I have tmobile and i refuse to pay the roaming charges they have for Canada- I plan to use a telus or rogers prepaid sim. Which one should i choose and why? i am only there for the weekend too so dont need a bunch of minutes or anything.
Also- i have put in a request to get my phone unlocked through tmobile. Once i have it unlocked- do i just pop in either a Telus or Rogers SIM and be on my way? or is there more to it such as flashing a specific radio??
Any help is greatly appreciated!

Can't help you regarding which operator to pick . I can however tell you that once you receive the network unlock code , simply pop in the SIM card and move on. That's all there is to it.

yup it's that easy
just punch in the unlock code and you are done
you can use any network you want, since our phone is Pentaband, it will work with any operator with a SIM card in Canada
might want to turn of auto DATA sync as it will eat up your pre-paid in record time
data charges are ridiculous on pre-paid cards, so use manual sync for only the stuff you need to find/get

Thanks for the reply guys- I received the unlock code from Tmobile today and applied it using an ATT sim card.
So i dont have to flash any modems/radios? saw something in another thread about that or is that strictly to gain 3g/4g speeds on those carriers?

Need Help Getting Sprint Network on Verizon Note 2

Okay, I'm sure the information is all out there, so before I get told to search forums or google, I have. My issue is that I'm just having the hardest time putting all the scattered information together and understanding it. There's too much information to decipher whats needed, accurate andd up to date for my situation. So I was wondering if someone whose done this before could just give me the straight to guide.
I have verizon, my girlfriend has sprint. She broke her S4. I have an old verizon note 2 that is unlocked, rooted, custom recovery and on CM11.
What I need to do is get it on the sprint network and get her service switched over to it.
I know it has something to do with APN settings, but there's so many different ones whether it's for internet and MMS. I basically just want her to be able to use it to make phone calls and maybe regular texts. I got all confused when I saw things dealing with PRL and what not, so I don't actually know which things I need to make this work.
I put the sim card from her S4 into my Verizon note 2 and opened the access point settings under mobile network. There are a bunch of sprint ones in there now, I don't know which one to choose. I tried the one just labeled "Sprint" and then rebooted to get the APN settings to switch over but I still have no service to try and activate the phone.
So could someone please give me a simplified walk-through of putting in sprint's settings on a verizon note 2. I tried flashing a Sprint CM11 rom but it failed. So now i am going to try flashing a sprint touchwiz rom to see if that will make all the necessary changes for me.
Update: I Just finished flashing jellybomb touchwiz rom, it flashed but wont get into the phone setup, says there's an encryption error and the phone needs to be reset. I did that and it still does the same.
Thanks in advance guys, I've flashed a lot of roms, I've just never switched my phone to another carrier before.

You can't activate a non Sprint branded phone on the Sprint network. Period. The esn is not in the Sprint database and even if you wanted to use the phone strictly for traveling internationally, The sim card from Sprint will not work in the Verizon phone for the same reason. You'd have to "clone" the phone/esn and that is completely illegal. I would spend my time on craigslist or Facebook and try to trade your Verizon phone for a Sprint one. That's what I would do.
FYI . Verizon phones are actually in demand due to the much larger customer base so making a trade for a Sprint S4 or Note 2 should be fairly easy. But MAKE SURE you check the ESN with Sprint before making a trade because a blacklisted esn phone can NOT be activated and you will be SOL.

So only networks like at&t and T-mobile will work on my Unlocked verizon phone?

If you're referring to your Verizon phone being a "world phone" which does in fact have a sim card and gsm network capabilities, then technically yes it would perhaps be possible to get it to work on AT&T or T-Mobile onl;y but it would be very difficult and time consuming to unlock the sim portion of the Verizon phone and hack it so that it would not be rejected by either network due to the ESN. You'd have better luck trying T-Mobile because they seem to be more lax with unbranded iPhones etc on their network. But in all honesty you would be better off trading your Verizon phone especially if it has a clear esn and getting a phone that's ready to go with no headaches and fully functional on the network.

thanks for the replies

[Q] Porting rooted Sprint G2 to Verizon

First, my apologies if this subject is already covered. I couldn't find anyone with a similar situation.
I have a Sprint G2 that I rooted and it is running CMod 11. I want to switch it to Verizon. I tried taking the phone to the Verizon store and they could not activate it for Verizon. I assume the phone is unlocked however because it activated just fine for Sprint and the Sprint guy told me that's an indication of being unlocked. True? Not sure.
The Verizon guys told me that I need to hack the radio frequencies of the phone before it would work with Verizon. I don't know where the settings are for this though. I already tried the trick of deleting 'Spr' out of a certain system file and I effectively bricked the phone. That didnt work and luckily I was able to revert to the stock rom.
My question is this: Can I get the phone to work with Verizon simply by flashing Verizon CMod to it? Or is it easy to find the settings for the radio frequencies that I need to change? Do I get any data once all is said and done? I don't look forward to unrooting and restoring the stock ROM JUST to hear Sprint say "Oh well we don't want to unlock it for you."

The G2 is only compatible with Verizon's 3G network. I doubt our radios work on the Verizon variant for LTE. Also, the IMEI would need to be whitelisted on Verizon's database. There's no other way around it. Better off selling the LS980 and buying a VS980 for Verizon.

1) no because the IMEI isn't in verizon's database / white listed
2) hardware for the radio is different then verizon's and you will be unable to get lte at all from it.
3) I would just restore to 100% stock (tot) and then sell it and then buy the Verizon version

i have inverse issue
well i bought a verizon variant, only because it was the only one with next day air delivery... I didnt do any research other than seeing that they had the same model number of 980 i figured a radio change and maybe rom change. i tried flashing a sprint rom on it it wont finish the install. do i need to get a sprint sim?

i might be interested in trading that sprint g2 for my verizon g2

[Q] Verizon LG G4 on Straight Talk Help

It's possible that Verizon hasn't pushed the update out to Straight Talk customers yet. Have you tried manually searching for updates? You can also download verizon's update utility and should be able to manage manually updating with your PC.
Also, what makes you want to take the update so badly? Nothing noticeably changes, plus you're jeopardizing your ability to root in the coming weeks.

I had the S5 and as soon as I sold it to my friend and he put his Verizon SIM in, he got that update. Was wondering if maybe it was a Verizon/Straight Talk issue. I read about what the update did, but was hoping it might help the touch issue a little. Thank you tho..I will consider waiting or try the veizon software after work today.

If anyone was able to successfully set up their Verizon LG G4 on straight talk, please help me out because I absolutely can't figure out how

I don't get this thread, Straight Talk says the Verizon G4 is incompatible with their service. I'm assuming OP is saying it works? What kind of speeds do you get with Straight Talk LTE on Verizon?

As far as I know ST doesnt really know what devices are connecting to their network, so as long as you have a clean ESN device compatible with their network, popping in the SIM should work just fine. If you really wanted to try you could probably ask for them to unbox a G4 in store and pop your own sim in to see if it connects.

LG G4 works on ST/Verizon if you use their CDMA kit. The only downside is speed is limited to 5mbps.

Wow...I didn't realize Verizon limited ST to 5Mbps... I just did a Speedtest with my ATT SIM on "H" and got 11+! I guess that answers my question about trying to switch over to a Verizon SIM!
Here I am fighting to get my G4's IMEI Cleared and usable on ST's page and it's really pointless anyway!

The 5 is not the speed of the phone on the network, it is the limit of data usage for the 30 days before they throttle you back to 2G speed.

That's not what they said... 5GB monthly limit != 5Mbps Speed Throttle...
I've been on ST for a couple years, I'm well aware of the Bandwidth limit and the following 2G throttle. (I've only been throttled once)
This was one of the things that kept me on ST(ATT) instead of switching to Cricket because I heard they Throttle to 8Mbps for LTE and 4Mbps for HSPA

I have been able to use the Verizon Update Assistant to upgrade my LG G4 on Straight Talk. The only thing so far that does not work is Advance Calling. In order to get VUA to work I had to turn of Developer Options for the program to see my phone. Unable to active it. This maybe an issue with Straight Talk, as I never looked at it before now. The update also changed my Software Status back to Official from Modified.
