the kaiser, t-mobile, and 3G

Hi everyone--
I have an unmodded, "unlocked" at&t tilt that has a t-mobile gsm sim chip in it. I'm still running the WM6 that came in it, and can't seem to get access to the 3G speeds I know this thing is capable of. I've tried numerous software apps to "force" the phone to go 3G, to no avail. T-Mobile customer "support"--HAA! tells me I need a t-mobile phone to be able to take advantage of the 3G speeds. Needles to say, I feel this is a bunch of malarkey. T-Mobile put out this phone, did they not, and called it the "MDA Vario III"? Is there a rom for the mda that I could flash this thing with so I could get the 3G speeds? Or another rom perhaps? Any suggestions would be most appreciated. Thanks!

Unfortunately, the malarkey is the truth! Because T-Mobile runs its 3G network on a different band than the Tilt is capable of! Sorry, this also effects me as I am a T-Mobile customer using a Tilt as well! My advice is to use Opera mini 4.2 for your internet browsing it is very fast on the Edge network!

The T-Mobile you refer to is European
It does not run on the same 3G as the US T-Mobile. The US T-Mobile uses 1700 Mhz and 2100 Mhz, I believe. The Tilt does not use the 1700 Mhz band. There was a rumor going around that there would be a new version of the Kaiser (KAIS140) that would use the US T-Mobile 3G bands but it was never released for sale. I don't think it will since it is pretty much at the end of the life cycle of the phone. They (HTC) have moved on to newer models with more features. If you would like to use the US 3G and live in an area with 3G, The T-Mobile G1 (HTC Dream) uses T-Mo 3G and has its own section on this forum.

bleh. newer models should still freaking tilt. that is the coolest thing about this phone. and it's pretty solid construction. my friend has had his over a year and its still going strong.

I thought the Tilt accessed 3G through it's tri band frequencies 850/1900/2100Mhz so that it could connect to most 3G networks worldwide, making it a world business tool for users?

True but T-Mobile uses the 1700 for upload and 2100 for download. ATT uses 1900 for both.

A few easy questions.

So I am currently looking for a G1 to buy.
It will be bought from ebay, and basicaly my questions are.
They say unlocked and that the mobile will work for any GSM network, does this mean no 3G network? My simcard allows my current cellphone to go in 3G and I woundering if this would change with the new phone.
And are there any good tips for me? To look out for while I'm browsing the G1 auctions and stuff?
Thanks in advance, Bread. <3

Unless you end up buying some kind of crazy G1 knockoff or a broken phone, it will work on 3G. Most likely 1700AWS (US T-Mo) and 2100 (pretty much the rest of the world).

Ofcourse I will aim for the real G1 ^^
No point in buying a chinese fake now is there? ^^
So should I aim for an unlocked one or can I do it myself?
(even though I wouldn't have access to any other sim than my very own.)

I'm not sure but I think I've heard of issues getting 3G with AT&T

The G1 will not work on AT&T's 3G.

Be aware that AT&T and rogers in north america operate on 1900mhz and 850 for 3g as T-mobile uses 1700 and 2100. Not sure about overseas as they use 2100 too. You would have to ask someone else about that.

AT&T 3G vs T-Mobile 3G

Trying to figure this out, Is the hardware basically the same. I read alot about UMTS and WCDMA, I am familiar with GSM vs CDMA, but I am not sure if this could work or not.
Basically I am wondering if a Google G1 on AT&T can run at 3G speeds. No need to tell you all the phone specs, I am sure your all aware.
AT&T
GSM 850/900/1800/1900MHz, UMTS 850/1900/2100MHz
TMOBILE
GSM 850/900/1800/1900MHz, HSPDA/WCDMA:1700/2100 MHz
Anyways from my HTC phones with AT&T I usually use 1900&2100 MHz
Is it possible to get this thing running on AT&T 2100, I figure if I was always roaming it would have to barrow some part of the TMO network, or does roaming only default to GSM 2G.
Another thing I think of is maybe updating my simcard with cingular so I can get a bigger network list or am I just dreaming about the whole Idea. It really seems like a software problem. Does that radio chip really make that much of a difference.
Again, is this not just a radio-build/sim config???
Thanks for any input....

It is not possible because the G1's HARDWARE does not support AT&T 3G. Only T-Mobile.

Im pretty sure you could use the rodgers g1 though for 3g on att

Yes the Rogers G1 has the same frequency as AT&T

Verizon HTC 1 to T-mobile

Hey everyone. So i have a question that i can't find on here so im going to ask it. I have a Verizon HTC one unlocked. The sim car works fine and i can do everything on the phone with the T-mobile sim card. The issue is its always Edge data. Is there a specfic APN i have to use? something im not seeing? Does anyone else have this issue? It is a stock factory HTC One, nothing custom.

I don't think the Verizon model will have the correct radio frequencies to use T-Mo's LTE or HSPA+ network, hence you're stuck on Edge. If you're staying with T-Mo, I'd suggest selling your current One and buying a T-Mo specific HTC One.

This is pulled from Verizons website
Network: LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(1900/2100) aGPS capable for E911 emergency location, aGPS (assisted), sGPS (simultaneous), Standalone GPS, eCompass, GLONASS
T-mobile uses the 1900 Mhz base band and the HSPA as well. So i don't see the issue in that one.

From what I can tell, nobody uses the dual 1900/2100 to achieve 4G like TMO. The UMTS referred to on that phone is for worldwide use, not US. So while it may have the frequencies, it is not set up to use them like TMO. Your software and firmware are set up to work with Verizon and overseas, not with a competitor like TMO. TMO refers to theirs as HSPA+. However, it might work on the new "reframed" 1900 bands (which is called HSPA), but those are not very highly deployed. Unfortunately, I don't see LTE on that list of frequencies. The TMO LTE is really great. EDIT: I mean TMO LTE, which is also 1700/2100.
I suppose you could try unlocking it and flashing the TMO radio, but there is an entire thread on trying to unlock TMO frequencies (in that case on the developer version), and no one has figured it out yet.
I concur that your best bet would be to sell the phone and get a TMO model.

Yeah thats what im thinking. I need to contact and t-mobile rep and see if the re-farmed LTE here. Ill call and ask.

Alright so i called the rep and he said the area i am has been re-farmed to the 1900 range and i should be getting at least HSPA/3G but im not. Very odd issue

Verison use the CDMA, maybe that's why you can only use 2.5G network, just like some phones in China, they only have GSM in common

yes but this phone has 4g lte already in it which accepts the sim card. Also, i have seen other verizon htc ones with t-mobile and never had a issue. I fell i may have to use a custom rom.

What he is referring to is that what Verizon uses as "3G" is CDMA technology. So although they (T-Mobile and Verizon) may be on the same frequency they're using totally different technologies. Just because it has a sim card slot for a Verizon sim doesn't mean the device will be compatible with another carrier's sim. A custom ROM would not resolve this issue. Your best bet would be to sell this device and purchase one from T-Mobile. :fingers-crossed:

I know what the best way to go is but i am very curious as to what is really keeping it from going out of edge. baseband? Is the TMO and Verizon radios the same? these are things i need to know! >.<

My understanding is that the devices run on different systems for 3G and different LTE bands. You wont get more than GSM compatibility (GPRS, EDGE). Hopefully it is something that a software hack can fix but if you read around all the HTC One forums you will see no one has found it. Right now it is not possible.

My question is that HTC makes phones for all T mobile verison sprint the same, so I believe its just software problem that we cant use Tmobile 4g lte on Verizon unlocked phone. SO does anyone have any comment for that?

It is hardware not software that is the issue. The T-Mobile variant has different bands than the other variants including Verizon. T-Mobile is a GSM variant while Verizon is a CDMA variant. Here is a comparison of the specs for the variants.

CDMA and GSM technology requires the antenna to be done differently. If they are not programmed to use those signals. Nothing you can dox will change it short of putting a new antenna in.

Because you can only unlock GSM. Cdma uses the serial/esn number of the device.

Has there been any update on this? I called tmobile and they said it was simply because I couldn't put in the APN. So, there's no chance that rooting the phone and putting a tmobile rom on it would fix the problem and let me get more than edge speeds.

I myself have been wondering the answer to this. The device might seem the same but under the cover they are different. The actual daughter board which the camera, vibrating thing, volume rocker, power button are connected to are fairly different from each other. The CDMA variant is not compatible with the GSM variant. Not even by adding a CDMA daughter board to the GSM motherboard and vice versa, the are made quiet differently and will not be able to use GSM bands on a CDMA m7

[Q] Local carrier has one phone using LTE, am I able to utilize it with the One?

Hello everyone,
I have a question I am hoping can be answered.
I used to own an HTC Dinc with that device I was able to watch YouTube no problem, however I can't watch any videos at all with this new phone.
I am thinking it's just slow connectivity*this is prolly it* but what's so different with my old phone to this?
My local carrier sells this particular model so I bought it second hand, it's a great device don't get me wrong but this one thing is killing it for me.
Is there a way to bring it back to the carrier and have them set it up to use the data like on my Dinc or am I just stuck with crappy connection?
Now with that all said, my local carrier markets 4G LTE but it has only one device which is an LG AS840, I actually asked if I can implement this to my One. They said they can't, I am wondering why wouldn't it work? Is it because the frequencies don't correspond with each other? Or am I missing something entirely?
All I want to do is be able to watch videos when I am not using WiFi*no internet at home atm, I have WiFi at work though*.
Another thing to add as well is, my girlfriend has an S3 which is AT&T branded, well to say it frankly her phone has much better connection than my One. I am also wondering about SIM unlocking, if I SIM unlock will I be able to use a SIM card from her carrier? Currently the carrier she uses is DoCoMo Pacific which uses AT&T branded devices while mine uses Sprint.
If anyone can enlighten me on this subject or even shoot down all my hopes I would appreciate it!!

Who is your carrier, specifically? If your girlfriend is on DoCoMo Pacific, I’m guessing you live in Guam. The Sprint One can only use LTE on the 1900 MHz G-block (Band 25). Currently, I believe that Sprint is the only carrier in the world that uses that frequency/block, meaning the Sprint One will only be able to use Sprint’s LTE network. Since this is part of the physical design of the radio/antenna, it cannot be changed.
Here is the full list of frequencies that the Sprint One can access:
2G/2.5G - GSM/GPRS/EDGE: 850/900/1800/1900 MHz
3G - UMTS/HSPA: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA: 800/1900 MHz for Sprint
4G - LTE: Sprint: 1900 MHz

In order to access the UMTS/HSPA bands, you would have to SIM-unlock. You would have to find out if there’s a carrier in Guam that transmits on those 3G frequencies (1900/2100 MHz) if you want to do things like stream video because the 2G/2.5G is very likely not fast enough.

My carrier is IT&E.
So doing a SIM unlock will help me at least switch to a different carrier, I was actually thinking about doing it just to switch. But as I was reading the various SIM unlock threads here, it's still pretty sketchy.
How about that LG AS840 using LTE on my carrier, or should I throw that thought out the window?
I will look around and see what kind of prices the carrier's offer, I dont want to be on contract so maybe prepaid is the way to go*I'm actually off contract but still pay my contracted amount.
This device is exceptional but the data speeds here locally suck.
