I was wondering if I can have internet with Verizon since our phones have WCDMA but keep my GSM phone service with my sim? I am sick of this T Mobile internet things not working with outr HTC branded phones in south florida. Anyone?
Negative. The radio will not work CDMA. The chip is not provisioned for cdma. You would need the MSM7500.
Yes that, and the fact that GSM is different then CDMA. If the kaiser supported both but gsm was the main one then you could probably do that but it doesn't.

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
I tried to get TMobile service for my Nexus one but it wouldn't pick up 3G. So I called Google tech support and they said my Nexus one is an AT&T only nexus one. What's up with that? I thought this was an unlocked phone able to handle any GSM carrier? Can I get it to work on TMobile?

maybe they meant AT&T 3G, it should pickup the EDGE network on Tmo or you are in a dead zone.

it will work on tmobiles edge service, but not on 3G. tmobile and att have different frequencies for their 3G signals. and yes, there are 2 kinds of nexus ones. one for tmobiles frequency, and one for atts frequency.
If I root the phone will I be able to use it on tmobile?
No, Tmobile runs 3G through 1700mhz band & ATT runs 3G through 850mhz & 1900mhz bands. Both carriers use 850/1900mhz bands for gprs & edge network. There is no way to change the frequencies your phone uses because its a hardware issue. This has been attempted many many times with the US always getting phones last.
This is something to determine when first buying the phone. Did t-mobile sell you the wrong version of the nexus?

There is a difference between "unlocked", meaning - any SIM can go in and the phone won't stop it from working, and "correct band for GSM/3G", which is in hardware - the phone has support for X different frequencies of GSM and Y different frequencies of UMTS (3G), and if the carrier you're trying to connect to doesn't work with any of those frequencies and works with some other ones - having a working SIM won't help you, since the phone won't find the working frequencies.
And this question was answered about 10000 times.
Will SGS Captivate 3G work on a 4G network?? I am curious, as i am looking for another carrier other than AT&T.
depends on what that other carrier is.
it will NOT work on 3g/4g tmobile network at all. hardware limitations
the '4g' networks that AT&T and Tmobile tout are all running on the same frequencies as their 3g devices, so its not like you are connecting to different towers or frequencies.
LTE is a different story altogether and requires special hardware and runs on separate frequency from 3g/4g(HSPA/HSPA+) networks
verizon and sprint us CDMA technology, so you wont be able to use it on those carriers either

I somewhere read that htc one supports both gsm and cdma network. which mean we can insert gsm sim OR cdma sim. Both will work.
So, is it really supports both network?

CDMA networks (Sprint, Verizon) don't use SIM cards, only GSM (AT&T, T-Mobile, etc.) networks do.
The Verizon and Sprint models contain both GSM and CDMA antenna hardware. If you have a CDMA device, you can get it carrier-unlocked (search the web, costs $20-30) and then activate it on another CDMA carrier, or insert an active SIM from a GSM carrier.
The GSM versions of the HTC One (AT&T, T-Mobile, International, Developer, Google Play Edition, etc) only have GSM antenna hardware. They physically do not contain the CDMA antenna. So these devices would only work on other GSM networks if carrier-unlocked.
So with your HTC One Developer Edition, it only contains GSM antenna hardware, you cannot use it on CDMA networks.
There are posts floating around suggesting to flash a different radio to "enable CDMA", but I'll tell you that flashing software cannot magically make a physical piece of hardware appear in your device.
Most of the GSM radio drivers are cross-compatible (an international radio driver will still work with AT&T and vice-versa). But the Verizon and Sprint models use specific radios for those networks.

Thanks a lot bro.
My son's AT&T S5 got stolen and my wife bought a US Cellular S5 off of Craigslist. My 1st thought was she got ripped off, but I took it in to US Cellular and they unlocked it for me. The phone doesn't have the option to switch to GSM network, so my AT&T Sim still doesn't work, but it doesn't say invalid Sim now. My question is this: is the modem GSM capable, but not listed? And if I root and flash another rom, will that enable the settings for GSM ?
I did notice the unlocked bootloader. I just rooted it very easily. Now if I can just get it to work on ATT.

the unfortunate answer is no, CDMA devices do not work on GSM networks.
Thank you sir. Guess I'll put this one up for sale for a Sprint, Verizon, or US Cellular customer.

Usually CDMA Phones wont work on GSM Network. But Verizon CDMA Phones does work on GSM too when unlocked as they have GSM Frequency.
I looked at Spec of US Cellular S5 and looks they don't have GSM Frequency. Its more like a strip down version and no GSM Frequency.
Here are the spec for
US Cellular
FREQUENCIES AND DATA TYPE
LTE: Bands 2/4/5/12/17; CDMA 1x/EVDO Rev.A: 800/1900MHz
Verizon S5
FREQUENCIES AND DATA TYPE
LTE: Bands 4/13; CDMA 1x/EVDO Rev.A: 800/1900MHz; GSM: 850/900/1800/1900MHz; HSPA+/UMTS: 850/900/1900/2100MHz
ATT
FREQUENCIES AND DATA TYPE
LTE: Bands 1/2/3/4/5/7/17; HSPA+/UMTS: 850/1900/2100MHz; GSM: 850/900/1800/1900MHz;

Verizon switched to GSM thats why there devices will ocasionally work as long as the freqs are the same (some arent)
they still also have CDMA/EVDO configs as well since their network is still supporting both once they complete the switch over (from what ive been told mid to late 2016) they will no longer support any CDMA devices.

Sorry to sound harsh but what you're saying is complete nonsense. Verizon did not (and is not planning on a) switch to GSM. They were, and still are a CDMA carrier.
The reason Verizon devices support GSM is so that their customers can roam in countries outside the US, some of which happen to use the same GSM frequencies as AT&T and T-Mobile do in the US (and therefore, by extension, support these two carriers domestically). And since all Verizon devices which include support for LTE are completely unlocked, in most instances you can take the phone and use it on AT&T or T-Mobile US. That said, when it comes to LTE specifically, these devices often do not have all of the LTE bands supported by T-Mobile and AT&T so on them they will often only work on GSM (2G) or UMTS (3G).
The reason the US Cellular variant won't work on AT&T or T-Mobile is because it looks like US Cellular didn't care about giving their customers the capability to roam internationally with their variant of the S5 - meaning they had the phone made in such a way that it doesn't support any GSM or UMTS bands at all.

I can tell you with 100% certainty that the person you talked to has no clue whatsoever (and Lord help Verizon if that is the level of technical understanding of their store managers ).
My suspicion as to where the confusion is coming from is that at some point in the future Verizon will stop putting CDMA radios in their devices and rely solely on VoLTE (voice over LTE) technology to provide voice services (currently most voice calls on Verizon are carried on their CDMA network). However, that certainly doesn't mean that they will be shutting off their CDMA service anytime in the foreseeable future .since they will still have a lot of legacy devices whose voice support will only be on CDMA. Nor does it mean that they are switching over to GSM, which is certainly not something they are planning on doing.

well like i said was info passed on by a verizon store manager so take that as you may im not a verizon customer nor will i be since they dont provide coverage where i need it.
Thanks for the info. I ended up selling the phone on ebay and now the guy wants to send it back claiming it's only unlocked for us cellular. I told him it should work on any cdma network, but they might have to flash it on their network. Oh well, if all else fails, I can use it to download movies and stream to the TV! Lol.
I'll install Kodi on it and use it as a media center.
Lol
