Okay so i'm in an area where T-mobile only has edge coverage and I'm hating my life right now without 3G, but AT&T has 3G coverage here, so why won't it let me roam on to the faster network? I can pull it up under network services but it just won't let me actually roam on to the network. Is this an issue of the phone simply not having the VPN's and such? Cuz if T-mobile won't charge me for roaming I damn well wanna use it! I'm using Cyanogen's Mod and the Hero 1.3.5 theme. All I want for my birthday is 3G!!!
They use different frequency's for the 3G signal.. thats why unlocked G1's can't use att 3g even if they have a AT&T sim
Hmm... seems strange the G1 would still be able to see the network being that it's using a different signal. Is there any way around this? Cuz they just stationed me in Quantico, VA for the rest of the summer and I'm ready to shoot myself on this Edge crap! And sadly 2 months is just too short of a time to actually get internet installed lol
hum.. I doubt it will help any but thier are som VPN settings floating around the board here that haykuro made. most ROMS come with it, I doubt it'll help though.
if that doesn't help take 2 Motrin and drink plenty of water. /end navy joke
Haha, yeah I'm a corpsman, we're working down here at the Marine Corps officer candidate school, so my mantra has been "Take Motrin, hydrate, and change your socks." These past couple weeks. Yet they somehow still mess those things up lol.

Im sorry to say but you cant use 3G on AT&T. Tmobile didnt want to wait for any bands in the 1700mhz or 1900mhz band to become available, so there 3G runs in the 2100/1700mhz band and that is the only band the G1 can use to get 3G. You can see AT&T service but that is voice, not 3G. AT&T 3G runs over the 1700/1900mhz band. here is a artical about this.

You must be barely outside of their coverage area. The map shows 3g coverage on both sides of where you are. The schedule that is floating around says they are supposed to expand coverage to Chesapeake, Hampton, Norfolk, Portsmouth, Richmond, and Virginia Beach this summer so you might get lucky and get it before you leave.
Quantico's huge, T-Mobile has no 3G service there, and WiFi is out as NMCI doesn't permit wireless APs.
You're stuck with EDGE on T-Mobile, or EDGE on AT&T if you roam, but you won't get a speed increase if you use it, just a roaming charge. The problem is the frequency, as others have mentioned. AT&T uses 850/1900 where as T-Mobile uses 1700/2100. There's no known way (yet *crosses fingers) to use a T-Mobile G1 with AT&T's 3G service, so sadly, you're going to be stuck for 2 months out there with what you have.
I have my Dream working on AT&T's 3G service, and it works quite well, but it's not a G1. I specifically bought a Rogers Canadian HTC Dream (which is band-compatible with AT&T) for this purpose. So if you're *that* desperate for 3G service, you could spring for a Rogers Dream or Magic phone, but they aren't cheap. Additionally, they don't run custom ROMs yet (we just got root on the Rogers Dream this morning, and the Rogers Magic was only last week). So... There is no perfect solution for you yet if you want 3G and root. I've been living on my ADP1 with EDGE for 5 months now, and it isn't *that* bad, I guess.
On the more "bleeding edge" frontier, there's speculation that if one were to flash the Rogers dream radio to the T-Mobile G1, that it would do 3G on AT&T instead of T-Mo, but nobody's been able to get it done yet. A few people say it's the same chipset, it'll work, a few others say it won't, but till somebody tries it, we'll never know for sure. Either way, it's not currently possible as we don't have a Rogers Dream radio image.
So, there's your options I'm afraid. And something else to consider - even though AT&T says they have 3G, check with somebody else who has their service to see if they're actually getting it first. Quantico is a huge base, and there's no cell towers on it to my knowledge. So it's possible that nobody is getting 3G signal there, on either network.
I'm a Cellular South user who's reallllly lusting after the Epic 4G -- sadly it looks like it's going to be the only Galaxy S slider released. Once the phone is released and rooted, would it be possible for the phone to work on non-Sprint carriers? I've currently got a HTC Hero, and I know for the longest time our ROMs were based off of the Sprint RUU.
Just curious if this is plausible, very likely, or not a chance in hell.
Thanks,
DrHogie
Sure it will be possible just like the Hero was. 4G won't be possible, but the phone will be able to at least make calls until you figure out any of the other stuff needed for data and market.
How compatible do you think this phone would be with MetroPCS? Also, I heard that LTE could be added with a firmware update on this phone, or at least phones like it. Is that true? If so, do you think it might work on other future 4G networks, like that of Verizon or Metro? Sorry for all the potentially silly questions, I've never shopped for a CDMA phone before.
LTE uses a SIM card I believe so without the hardware built into the pone, you couldn't use it on that kind of network.
I read a blog with an interview of a Sprint higher up saying that they could potentially change the technology of 4g quickly and cheaply in places that currently have 4g. However, I don't know if that means another set of GSM 3G vs CDMA 3G like we have now. Maybe it would be a CDMA LTE that doesn't use a SIM?
Hopefully they just leave well enough alone. I know the technology will be different at Verizon (LTE) and T-MO(HSPA+), but differences usually foster growth for the best to keep up. I guess that would also eliminate a roaming data possiblity.
Who knows...lots of questions.
LTE isn't CDMZA based, it is its own beast.
This is where I read about the SIM card http://gizmodo.com/5590530/leaked-documents-and-lte-sim-show-verizon-4g-launch-is-imminent
Wikipedia is more info if you search LTE about the technology.

Being that Verizon and Sprint use two different bandwidths I'm going to say it wont work. Its like trying to pick up FM with an AM radio.

Sprint and Verizon's 3G are compatible with each other. That's why Sprint phones can, or used to be able to, roam on Verzion's network...
Sprint and Verizon's 4G networks are not compatible, though.
Sprint and VZW still roam off each other... so the freq's aren't an issue.
I guess it depends on whether or not you upgraded to the 4G radio.
Can it operate on Sprints network? yes, will sprint allow it? probably not. Sprint employees have to let the device work on the network and technically they're not supposed to do that, but if you're good friends with a sprint technician maybe you can talk them into it.
There seems to be some confusion about this phone working on T-Mobile 4g
YES THE PHONE WORKS!! however if you want 4g you need to be in a 1900 refarmed area and yes LTE works as well.
I live in Katy, Texas which is a suburb of Houston which is a 1900 refarmed area. Phone works perfectly fine. I didn't have to do any set up. Basically just like a tmo phone. I haven't noticed LTE yet. It switches from 3g to H. Runs just as fast as my nexus 4 and one s. Just thought I would drop this info, hopefully it helped someone.

I would like to confirm that the Unlocked 32GB HTC One works perfectly in Phoenix, AZ as well. We're another 1900MHz refarm, and I've spotted LTE in some areas as well. Don't be afraid to grab this from HTC rather than dealing with T-Mobile's shinanigans and bloatware.
I'm in the boston area, which is also refarmed. pretty much same experience as op. all the set up was automatic.
the only thing different is indoors, sitting at my desk which is 3 feet from the window, my phone switches between E, 3g, and H every few minutes like it cant get a stable connection.
havent gone outdoors yet.
Speedtest during H connection was: 104ms ping, 5.13Mbps down, 2.07Mbps up
this is comparable to my g2 speedtests

Working faster than my galaxy nexus around chicagoland, only problem is that I cant no longer tether even with the mod UAstring but If I switch back to the galaxy nexus everything works fine. We need to fix this issue ASAP
I live in SD, our refarm is kind of strange and this is the first time I've ever used it(only used primarily tmobile phones for last 10 years). The one thing I will say is that it in SD it seems every other tower has been refarmed, as I will keep going in and out of HSPA. This was seen as I was driving around on the freeway(not texting but checking service). Another thing is that I can be on a tower that has been refarmed, go into a building, and have it revert to edge from HSPA outside. And then when I take a couple steps outside the building it works again.
Also I was wondering if anyone else has handcut their sim to microsim? I'm hoping that may be the issue, and if I get an official tmobile microsim it will be fine. Otherwise the refarm is superb when it works, getting about 10 Mbps down with my handcut(from diagram) sim
Houston Area
The Developer Edition work fine in Houston area. However, the data speed is jumpy. My Note 2 LTE speed stay above 15 MBS all the time but the One LTE will go from 5 MBS to 20 MBS. H+ on the one is not stable at all. Tmo agent told me to call back in a week for more info. If someone find out a way to optimize the Dev edition on Tmo radio please let me know.

Finally got tethering working by using FoxFi and I get around 10mpbs, the stock one that comes with the phone doesnt quite work for tmobile.
New to the htc one but what is the tmo radio required for? Since it already works unlocked?
If I'm not mistaking it's 1700/1900/LTE out of the box the unlocked one doesn't have 1700 enabled. I'm sure a dev will eventually get it done. If you want 3g/4g data then you need to be in a 1900 refarmed area.

The ATT/dev ones are 850/1900/2100MHz UMTS; band 4 (AWS) is the only UMTS band that uses 1700MHz at all.
I wouldn't count on getting AWS enabled on the dev version. It is very likely that the allowed bands are configured in hardware as has generally been the case on MDM9x15 devices.

The unlocked version is strictly worse from a 3G standpoint but might have a couple of extra LTE frequencies (not 100% sure on that one, tmo version definitely is bands 4/17 only). AFAIK the only other place AWS is at all likely to matter is Canada, but assuming tmo will unlock your One there is no frequency advantage to getting the unlocked version from HTC--I think it's $5 cheaper.
If you travel internationally then that's a huge advantage.. but I'm sure tmobile will unlock your phone, if you ask. I purchased the unlocked version because I didn't wanna deal with my uncle (account holder) nor tmobile. Plus there wasnt any information about tmobiles release at the time, I so I hopped on the unlocked version.

I'm having the same issue with T-Mobiles Refarm @ 1900mhz keeps dropping from H to EDGE, and I just spoke to my Buddy that works for T-Mobile and there LTE will be on AWS 1700MHZ... I'm shipping this phone back to HTC, I was thinking of buying T-Mobiles HTC One Branded phone that includes the AWS 1700mhz Band, but I don't like the fact that its only a 32GB.

After checking in to why this would not work I was told that it just isn't supported. You can use 4G and wifi data duringa call but not 3G. It's a little bit ofa draw back for me. I was just wondering what any one else's thoughts where on this?
I do like the phone so far other than this.

I'm taking a chance on sounding silly, but that's just the way it is on CDMA networks. You can only do one or the other on 3G: voice or data. Being able to use voice and data simultaneously is a perk of 4G, LTE or wifi. Of course, if you have no LTE available where you are, or no wifi, it's voice or data. I know it's frustrating. I live in Minneapolis, Uptown area. We never did get very good Wimax at our house, especially indoors.
When the LTE phones came out, I was in no hurry to upgrade, as there was no LTE anywhere in the Twin Cities. No one could hazard a guess as to when it would be rolled out. The Evo LTE has been out for almost a year, and LTE is finally becoming available. It's still pretty spotty, though. The good thing is, even with a weak signal at my house, I still can get nearly 5000kbps down inside my house. That's a lot better than 3G for sure! Sprint is saying we'll have LTE pretty much throughout the city in the next couple of months. I'll believe that when I see it.
I like my S 4 pretty well. It's still strange getting used to Touch Whiz after Sense. I moved to the S 4 after having the original Evo and then the Evo 3D. I'm looking forward to rooting and being able to run custom ROMS on my S 4.

That's not exactly accurate. Some phones can do simultaneous CDMA voice and data. However, it requires extra complexity in the phone (what's called "multiple paths") and with Sprint going to LTE, they decided to put a separate transmit path in the device just for LTE (and Wi-Fi).

There's no harm in sounding silly. :silly: We forgive you.
The Sprint S3 and Evo 4G LTE both do it, it's called SVDO, simultaneous voice and EVDO 3G data (and ofcourse simultaneous voice and LTE and or WiFi).
For some reason, Sprint decided to fore-go SVDO on LTE phones after those two (S3 and Evo 4G LTE) and instead focus on SVLTE. To be fair, in all the years i've been with Sprint (13) i never thought i would ever need or use that feature until i got the S3. The first time i unknowingly used it i didn't even realize that while on a call, i was playing WordFeud multiplayer. It's something i do all the time now, and definitely sad to see it gone on the newer phones.
As their LTE network gets more robust and mature, it won't be much of an issue, but as of now 3G is in more places than their LTE network is. So...

Thanks to both you guys for setting me straight. I was parroting what I'd always heard from the OG Evo (which I had) and then the 3D, which I just left. Of course, you couldn't do SVDO on either. On the 3D, though, you could do a call + data if on 4G (Wimax), which was and still is, pretty spotty here in Minneapolis-St Paul. Of course, Sprint has been rolling out LTE for a while now. It appears, then disappears a lot. Unfortunately 3G has been awful for months. I will be so thankful when LTE is finally and fully deployed!
No problem, welcome. We are all here to help and learn from each other along the way. :good:

Those devices did not support SVDO. I know the S3 and EVO LTE support it, and possible the Nexus LTE (additionally, the newest Optimus maybe?). I really liked this feature when on the phone and being able to quickly check email or pull up traffic info without relying on WiFi.
The S4 does not support simultaneous voice+data, and I believe that anandtech/ars had good articles describing the data paths employed by the HTC One and S4.
What I found interesting is that when the 4G connection drops out and 3G connects, I can just send a text and get 4G back immediately instead of waiting to hop towers. I suspect that a phone call would serve the same purpose.
Also, toggling 4G off and on will get you back the same mobile IP address. This is not the case with 3G, which results in a new IP address being assigned. In order to get a new IP on LTE, you have to toggle airplane mode (which is likely why this is the first step in troubleshooting LTE connectivity).
Thought I'd help you all out to understand it since you all are sooooo new to having LTE on your phones and all (that was a joke, don't get bent out of shape over it....)
The LTE standard only supports packet switching with its all-IP network. Voice calls in GSM, UMTS and CDMA2000 are circuit switched, so with the adoption of LTE, carriers will have to re-engineer their voice call network. Three different approaches sprang up. Most major backers of LTE preferred and promoted VoLTE (Voice over LTE, an implementation of IP Multimedia Subsystem or IMS) from the beginning. The lack of software support in initial LTE devices as well as core network devices however led to a number of carriers promoting VoLGA (Voice over LTE Generic Access) as an interim solution.[13] The idea was to use the same principles as GAN (Generic Access Network, also known as UMA or Unlicensed Mobile Access), which defines the protocols through which a mobile handset can perform voice calls over a customer's private Internet connection, usually over wireless LAN. VoLGA however never gained much support, because VoLTE (IMS) promises much more flexible services, albeit at the cost of having to upgrade the entire voice call infrastructure. While the industry has seemingly standardized on VoLTE for the future, the demand for voice calls today has led LTE carriers to introduce CSFB (Circuit Switched Fallback) as a stopgap measure. When placing or receiving a voice call, LTE handsets will fall back to old 2G or 3G networks for the duration of the call.

Just to be a bit more clear, it was not a sprint decision it is based on Qualcomm's chip design. The s4 krait simply supported svdo out the box and the snapdragon 600 doesn't.

I am not sure that is correct. First of all, the 600 is the CPU, not the modem - which is a separate component altogether. Secondly, I believe SVDO support is more a factor of the front end RF design being set up to feed multiple transmit paths to the modem, which in the case of the Qualcomm modem, I believe has the necessary additional ports to handle it. However, it would have necessitated a more complex RF design which Sprint and Samsung probably opted to forgo, given that Sprint's is already getting on the LTE bandwagon.

My best guess is that the advanced modem in the S4 could handle it, but to add it on top of SVLTE along with the newer MIMO antenna configurations and multi-band transceivers and switches found in the latest LTE capable handsets would require the addition of another RF chain in the device and thus significantly raise the complexity of the design to a degree that doesn't make it worthwhile for Samsung to implement it.

Yes, for the most part, cdma devices has never been able to do voice and 3g data simultaneously but there is something called svdo which allows supported devices to do just that. The HTC thunderbolt on verizon was one of the first phones to support svdo(simultaneous voice and data over 3g on a cdma network). Getting it to work has absolutely nothing to do with the network but how the phone is designed. Now I am a sprint customer so I don't know what other devices supported it on verizon since but I do know that both sprint and verizon's gs3 both support svdo as well as sprints evo lte and a few other devices.

Not true. There have been several devices that could do it.

You keep talking like the network is preventing it from being possible, yes there are technical obsticals but obviously there are ways around it. So the botton line is, can you have a phone thats on a cdma network that can do voice and 3g data at the same time? That answer is yes
Seriously, why are we arguing this much about this? Simultaneous voice AND 3G on Sprint, yes, period. S3 and Evo LTE do it, S4 doesn't. Let's move on to other things.
