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.
I have a friend who currently has a Sprint BB (Tour) with a SIM card. He's looking to get the Captivate because it has a SIM card slot. I already know of the two different Network Types (GSM vs CDMA), and their different network frequencies. I was just curious if that SIM would work in that phone?
I would highly doubt it. But give it a shot
Sent from my captivate so excuse the spelling mistakes
Thanks, but I also read that the frequencies supported in the BB include the ones supported by AT&T network , 850MHz and 1900 MHz. We will just have to see tho..
No. Sprint & Verizon used CDMA networks. AT&T and T-mobile use GSM. Completely different radios. Square peg/round hole.
Thanks. I understand the CDMA/GSM differences, just thought that the SIM would support GSM networks and with the Captivate being a GSM phone, it would just work. But w/o an AT&T account, that just really wouldn't work out.

Sprint sim in the BB is for overseas use making it a global phone. The sim that is in there should be Vodafone or something like that. It is so it can be used in the UK or accross the pond.
You can have the BB unlocked and put an ATT sim in it and use the edge network but no 3g. But the sim that is in the BB now will not work on ATT network.

Negative. It's not for use overseas like Verizon's BlackBerry devices.
The reason for the SIM Card in the Sprint BlackBerry devices is for connection to the old Nextel IDEN network for their push-to-talk system.
What that means is, though, that it will -not- work in a Samsung Captivate because though the IDEN SIM is the same size/shape as a GSM SIM, but they are not even remotely the same. Still square peg/round hole like a previous poster said.
Now that we can SIM-unlock our Sprint HTC Ones, I've been curious about buying a prepaid a T-Mobile SIM to use when I can't get LTE or decent 3G. My friends on T-Mobile get great HSPA speeds (even when it's just HSPA 14.4) around Chicago, usually in places where my data sucks.
Ideally, I would like to pop a T-Mobile SIM card in my phone, but still receive calls and texts on my Sprint number without setting up some kind of forwarding service. Unfortunately, I suspect that SIM cards don't work in this fashion, though I am hopeful because the removal of the SIM on the Sprint HTC One simply cuts off support for LTE (probably because the only purpose of the SIM card in the Sprint HTC One is to authenticate LTE, but I'm not totally certain).
Alternatively, could I jump between my Sprint service and T-Mobile service if I installed a T-Mobile SIM by using the *#*#4636#*#* menu? Say I chose "EvDo Only," would I connect to Sprint 3g and get calls and texts on my Sprint number and simply select "WCDMA Preferred" when I want to use T-Mobile's HSPA network?

On paper you should be able to connect to HSPA 14.4 on 1900MHz or 2G on 1900MHz. In actuality I don't know but there have been several other threads discussing similar topics. Here's one: http://forum.xda-developers.com/showthread.php?t=2386408
When I tested my T-Mobile sim, once I went into mobile networks and selected it, my phone number and my sms was thru the T-Mobile. So I don't think it will work as data only by default at least not saying that it is not possible, just sharing what I experienced.

Oh, this I know, thanks though. Actually, I was telling someone else just that earlier today:

The Sprint HTC One ONLY supports LTE on band 25. There are currently no carriers in the world other than Sprint that supports LTE on this band.
http://en.wikipedia.org/wiki/List_of_LTE_networks
EDIT: Oh, and the Sprint HTC One supports HSDPA on the 1900/2100 MHz UMTS bands up to 14.4Mbps, which is is slower than a lot of HSPA/HSDPA speeds available now (21.1Mbps and 42.2Mbps), though still more than fast enough for browsing or even streaming.

So you can leave a T-Mobile card in there and just switch between Sprint 3G/voice as well as T-Mo 3G/voice at will? That could be useful; for example, my favorite bar is a total dead zone for Sprint data, but T-Mobile flies. When I know I'm going there, I could pop a T-Mobile SIM, switch to that to check websites and whatnot, but switch it back to periodically check my text messages, right?
That I am not sure. I only tested with a friend's sim card from his nexus 4. With the Sprint sim card removed I was still on sprint cdma but once I went into the available GSM networks and chose T-Mobile, it registered and I was no longer on Sprint at all and it shows GSM icon up where my signal is at. Made a phone call and phone call came thru under my friend's phone number instead of my Sprint number. I'm not sure about sms I did not really played around with it long enough as I was just testing if the unlock really worked.
yes it work

Hmm... I might just stroll over to a T-Mobile store today, activate/pick up a SIM for $10, and spend another $3 for the daily pay-as-you-go plan. 200MB for $3 isn't bad if you need it in a pinch...

I've heard of these issues, does it happen if you stay in the same spot? Have you tried different modes in the *#*#4636#*#* menu other than "WCDMA Preferred"?

Just an update: I went to a T-Mobile store over lunch to buy a SIM. I was prepared to drop the $10 for the SIM and $3 for the day pass, but it turns out I would need to buy a $10 minimum plan first. >:-\
I'd rather not spend $25 after tax just to see if it works. I'll ask my friend on Sunday if I can try hers. Hopefully I'll be in an area that's covered in 1900/2100MHz.

Where did hi did the guide to sim unlock with domestic carriers?
I was under the assumption only foreign SIM cards worked.

Once ur SIM unlocked it will work with any SIM card ur just limited on the antennas the phone has. Our phone supports voice 3g and minimal 4g on domestic carriers. The 4g has to be on 1900/2100 mhz in order for this phone to pick it up

Ehh... Not really "4G" since the Sprint HTC One only supports LTE on 1900MHz band 25. T-Mobile uses 1900/2100MHz for HSPA, and the Sprint One only supports 14.4Mbps on those HSPA frequencies (much slower than T-Mobile's phones support).

I see what you're saying, and I think that you're right, but their HSPA network (which they suddenly started calling "4G" strictly for marketing reasons) is significantly slower than most LTE networks. Only phones that would run on HSPA 42.2Mbps would give Sprint phones a run for their money. HSPA was never classified as even being a pre-4G network by the ITU. I think that only WiMAX and LTE hold that distinction. Anything that's HSPA but marketed as "4G" is a lie.
Sent from my Sprint HTC One
If you're in a Sprint 3g only area then t-mobile if on 1900 hspa is still faster. If you integrated your sprint number with Google voice the you can still get your sprint text messages from the Google voice app and use an app like talkatone or groove ip for voice over ip

So I am not intending to get into a large debate about the HSPA ver of 4G vs the LTE networks other than to say that the top four carriers are not really using LTE to its truest potential because they're limiting backhaul connectivity to keep costs down. So that LTE network you're connected to doesn't have the fastest ethernet connection it should so in many cases it is "possible" for 42MB HSPA network to actually be faster in its actual deployment.

I have a Nexus 6 that I bought from Motorola.com and am using it with an activated nano sim card on Verizon. Previously I have had no problems with getting signal (LTE or 3G) but now that it just updated to 5.1.1 I can only get 3G when network settings are on "LTE/CDMA" and I get LTE when set on "LTE/GSM/UMTS". I am in an area that has pretty strong 4G but cant get it unless I change the setting. Has anyone else had a problem with this? Also I am open to suggestions for alternate ROMS that have been found to work well on Verizon. Thanks.

Verify that you are using the correct APN. However, I believe the correct setting for you would be LTE/GSM as Verizon is a GSM carrier.
LTE/CDMA works fine for me on Verizon.
Verizon is not a GSM Carrier. They are CDMA just like Sprint. The only reason both companies use SIM cards is for LTE only.

Thanks for clarification! I thought AT&T was the other CDMA and the rest were GSM besides Sprint. Again, thanks for setting me straight.
AT&T and T-Mobile are GSM, Sprint and Verizon are CDMA. Just for future reference.
Hello everyone! I am trying to switch over to Straight Talk because my current carrier, nTelos, has been bought by Shentel and I was told that my current phone could not be used on the new network. Even though nTelos goes off of both the Sprint and Verizon network, my phone will not be able to use the new network that is owned by Sprint. (Which honestly confuses me since my phone has been running off the nTelos, Sprint, and Verizon networks just fine.)
Anyways, I was wondering if it was possible to use the AT&T or T-Mobile sim cards that come with the Straight Talk activation kit. I am wondering because AT&T, T-Mobile, and Verizon all use 1900MHz on band 2 for LTE. Also, the AT&T and T-Mobile variants have some of the same LTE bands as the nTelos variant. So, is it possible or should I just stick to the Verizon sim card that came with the activation kit?
Never mind. I can't get any of the sim cards in the kit to work with the phone.
