You will only be to access 2G/edge data speeds, no 3G connectivity since AT&T uses different 3G bands.. assuming you are currently using a T-Mobile G2 with the carrier T-Mobile... :?
You won't have any signal issues unless AT&T has horrible coverage where you live.

you will not change anything hardware related... you just unlock/root your phone which allows you to modify hardware and software related things. But if you don't touch the antenna software then nothing will change
@CaliBoyPhillip; when I was in the states my phone switched from AT&T and T-Mobile all the time (roaming) and still had 3g reception, the phone supports most frequencies.

no im currently using a Aria with AT&T but im getting the G2 or the G2X tomorrow. and ok so i wont lose my 3G?

G2x will work with At&ts 3g/4g. As for G2 I was told it doesn't support the 3g/4g from at&t. Remember the buy out isn't final yet.

hmmm Interesting... it was prob due to the reason that you were roaming but if he uses an AT&T SIM on his SIM unlocked G2 from T-Mobile, he won't have 3G access I think... The G2 runs on 850/900/1800/1900 for edge and 1700/2100 radio for 3G data, meanwhile AT&T operates on 850/1900 for EDGE and 850/1900 for 3G.... not compatible !
EDIT: source for the bands ATT uses for 3G gotten from here.. http://www.att.com/gen/press-room?pid=14003

THis is correct. The G2 WILL NOT work with ATT 3G. If you want 3G you need to purchase the NAM (North American Model) of the Desire Z. It is sold in Canada on the Bell Network. You can find it online unlocked and unbranded and it WILL work on ATT no problem. It is going to cost you though, 450-550 depending where you get it.

Same reason iphone won't connect to tmobile 3g...amazing people still don't understand this

Nope, the phone's hardware is what decides what bands it can use.

Get a desire Z from rodgers Canada the 3g bands are the same

To bad radio isn't software
It's to bad that phones don't have the radio frequencies programmable in software (much like an fm radio). Is that even possible?

The forum you're looking for is here...
http://forum.xda-developers.com/forumdisplay.php?f=1539
But to answer your question, no, neither the Teg3 One X (this forum) or the AT&T One XL support T-Mobile U.S'. AWS bands. There's a thread in the other forum where people are trying to get it to work on Wind Canada which is also AWS. No joy so far.

[Q] Verizon HTC One AT&T Sim

Hi,
I purchased Verizon HTC One from craigslist it was mentioned that it is pre-unlocked phone. I have used T-Mobile sim and it is working however when I tried AT&T sim in it that didn't work. It shows at top that network is AT&T but I am unable to make or receive calls. I was able to use data on AT&T's edge network ( though my sim is LTE). I know that both T-Mobile and AT&T are GSM networks and this phone is CDMA/GSM. Does anybody else using AT&T sim on Verizon HTC One? Do I have to change some kind of settings??
Regards,

Hello,
I have the same Verizon phone and I'm using T-mobile network, but I can't get data started. What APN settings did you use? If
you could please help I would greatly appreciate it.
Thanx,
SiouxV

You will only get edge because Verizon blocked some of the bands that you would need for hspa speeds.

You will have to change settings to gsm/umts as att uses. Settings>mobile data> preferred network. Also Google att 3g apn settings and edit son. You won't get lte but I don't see why you shouldn't get 3g.

Weird because I have a straight talk att and tmobile SIM card with correct apn's set and I only get edge. I know tmobile reformed my area to the 1900 band too. If I pop those SIM cards in my droid DNA I can pick up HSPA speeds with the same apn settings.

That is weird. I would assume if gsm/umts is an option that HTC would have also included the correct bands but nothing surprises me these days.

I think it has only the 1900 and 800 band. Not the 850, which you also need for 3g. Or Verizon blocked those bands despite the phone being factory unlocked.
Sent from my HTC6435LVW using Tapatalk

There's an app called "LTE On/Off", not sure if can download from play store, but included with certain Roms. It allows you to pick different bands. You can select HSPCA/GSM etc. Maybe this will help with other networks??

I'm not sure. On android central I have a thread there about the Verizon one. A person there says he tried it on straight talk with an att SIM and got hspa speeds. I tried both an att and tmobile SIM card in my Verizon one and only got edge with both apn settings. And tmobile rolled out the new bands where I live too. At the time my one was not rooted so I didn't have that app.
Sent from my HTC6500LVW using Tapatalk

could you flash a new radio? Seems like that might help.. and if the hardware is the same and you get the bootloader unlocked, root the device, and achieve s-off could you re-flash firmware, radios, hboot and rom could it potentially operate as a modified at&t (or other gsm) htc one? sorry if this is completely wrong I'm not a firmware guy.. I know basics of rom's and installations that's about it just throwing an idea out there...

Not sure, but you could unlock your cid setting it to all 1's and flash a gsm edition Rom or ruu, flash radios too. Not sure weather it would work or not depending on the Verizon model hardware but all that stuff you can do.
Turns out the guy on android central was wrong, he was also getting edge data but didn't know it.

Are any of you who are trying to use the phone on AT&T running a custom rom, e.g. Cyanogenmod or Santod's Global Edition?

My one max works on at&t fine once you add the apn settings for at&t.

The Verizon one does not have the same frequiences unlocked that require you to have 3g. The DNA has pretty much similar radio frequiences and gets hspa but the HTC one has those bands locked so you only get edge, even with apn settings.

Great. It's usage like this that was a big contributor toward the unlimited data plans going away. Thanks. This is why we can't have nice things.
Back on topic, I'm curious as well if flashing new radios would do the trick.

They would have to be fully compatible and I'm not sure they would be. Maybe possible but I have not tried. Mainly one reason why they stopped selling the DNA.

So the consensus here is that you cant do any better than Edge service when using AT&T SIM in a VZW HTC One?
See, I just swapped my Note 3 AT&T for this phone, and Id like to be able to use data. I use AT&T prepaid but my Note was always able to pickup HSPA and LTE

Have any of you ever tried doing a factory reset from hboot? That will clear out all of the network settings from verizon, and force the phone to be reprogramed from the sim.

I have, with TikTak Google Plus Edition 2.0, I'm still only getting EDGE data (same as with stock) I have tried using a gsm rom, radio, and RUU. The phone wouldn't start with the different radio flash, the RUU would just boot cycle, and the rom would always fail (status 7, 6, 4).
I have spend about 20 hours on this flashing separate roms, radios and pretty much anything i can find

The same problem is getting me as well. According to the Network provider(WaridTel Pakistan) this model of HTC One M8 is not supported in Pakistan or Carrier Lock something even the LTE option is appearing in network modes. Meanwhile 3G and edge is working perfectly.
HTC one Mdoel Name: OP6B160
Network: waridTel (LTE 1800 MH)

Data issues

So I have a Verizon model M9 using it with a GSM sim. Its a data sim which can roam on both T-Mobile and AT&T.
Here is my issue, T-Mobile is only EDGE in my area, and the phone works perfectly fine on that, but for some strange reason on AT&T HSPA+/3G It will work for a few min and all the sudden stop working even though "H" will still be at the top of the phone like data is there when its went away.
Its not the carrier, or the sim as this exact sim works perfectly fine with my Verizon G4, iPhone 6S, iPhone 5, and so on with no issues.
Any suggestions for those who use this model on another carrier? Or any suggestions what May be causing this?
I've changed my SKU, S-off, root, etc even running stock roms (non verizon roms) , same issue so its not Verizon software causing it. Also tried setting it to WCDMA and other settings and the issue still occurs.
Any ideas would be great! I really like this phone and hate to have to sell it and go find something else or may end up going back to my G2 for my 2nd line. Could Fast Dormancy cause this?
Thanks!

You're going to be handicapped by the physical limitations of the Verizon M9. Check out what bands T-Mobile & AT&T use and see which ones match up with your moel. The bands that the Verizon HTC M9 supports are:
LTE Band 13/4 (700/1700MHz),
CDMA/1xEVDO Rev. A (800/1900 MHz)
EDGE/GSM (850/900/1800/1900)
HSPA/UMTS(850/900/1900/2100)

Thanks but it's not a matter of being supported. It supports AT&T 100% 2G and 3G wise. I get HSPA+ just fine without issue its a matter of the phone some how loosing data connection randomly until putting it into airplane mode or rechoosing the network under network selection. But it's fully supported AT&T 3G wise.

Thanks I might try that. Yeah it's not the matter of the bands is the issue.
What's strange is I'm not having signal issues as signal is perfect it's just the weird loosing data issue while signal is perfectly fine. But worth a shot.
