So I broke a phone and a friend gave me a Sgh-t679 for TMobile... I did a little searching and I see I pretty much have to pay for an unlock code... If I pay for a code can I use it on Verizon as they use cdma and lte? And as they use a micro Sim? I thank you kindly for your time I greatly appreciate a reply...

:what: You cannot use a GSM phone on a CDMA network. :banghead:

Thank you kindly for you reply... I was just checking, as in *#*#info#*#* menuthere is the option cdma only... So I take it, that statement was your kind and polite way of saying "no sir, unfortunately this is a GSM only device and you will not be able to use it on a CDMA network"....so if that's the case I thank you for that...

There is a difference with what you are talking about and what your asking. What you asked refers to hardware, the modems are not compatible. Roaming is slightly different. Most CDMA carriers do not use a Sim style card, as far as I know Verizon is the only company that does. In the U.S. there are a few gsm carriers that would work with the t679. But it will never work on a CDMA network. For more info on the difference between CDMA and gsm check Google, there are several articles explaining why its not possible. That's how I knew the answer to your question to begin with.
I am using ATT. ATT is also gsm. Verzon is cdma. You cant use a gsm phone on CDMA. Sorry:crying::crying:

Apparently they now carry 4G SIM cards to allow access to their LTE network (see here). The details are a little sketchy, though, and I wouldn't bank on it working.
If you're really interested in doing this, I would suggest going directly to a Verizon store and speaking with someone there. Maybe even see if they'll let you test it out (probably not, but it can't hurt to ask).
The only other Verizon sim cards I found were international ones that allowed roaming on Vodafone's network. Since Verizon in the US uses CDMA for its non-4G network, SIM cards don't work. With a non-4G SIM card you would end up piggybacking on some other carrier's network.
That's my understanding, anyway.
Okay I have a droid incredible 2 it got damaged but it has a sim card its not 4g either so yeah

That's one of the international sim cards, which basically just lets it hop on GSM networks internationally when it doesn't have Verizon's US CDMA network.
So you mean its not possible
Sent from my SAMSUNG-SGH-I897 using XDA App
I can't say for certain. You would need to talk to someone at Verizon and ask them if their international GSM sim cards work here in the states.
My guess is that they'll tell you it will work, but since you would be essentially roaming all the time you're using it, it would be either costly or they wouldn't do it. Again, I'm not a Verizon employee, so I can't say that's 100% accurate, but that's my gut reaction.
Yeah ok makes sence my incredible 2 can only go into safe mode thats why I ask this

Yes but verizon is so protective you have to have them activate it through the phones imei

Unfortunately verizon does not like you to be able to use at&t on there global phones so afaik there's no way to make it work.
Getting my droid 3 from ebay tomorrow. Do i need a sim if im just using it in u.s.?
It isn't the question but the way its asked.
That depends on what you intend to do with it. For most users, no.
No I have my global sim card out and it does not require a 4g sim either because... well because its not 4g.

That's not a stupid question. You need a sim card to use it in the US as well.

This is a Verizon phone and Verizon has never used sim cards because they are CDMA. The sim card slot is for GSM signals in other countries, since US based GSM providers like at&t and t-mobile are blocked on this.
Thanks for the replies. It came with one....but as I found out, its not needed for U.S. operation. BTW....loving the phone(even without root).
At my second job my company is sending me a Sprint HTC one to use as my work phone and they want me to activate it on my Sprint account or they'll pay the deposit to open the account if there's one. But where I live I don't good coverage from them and there 3G is SUPER SLOW, I can't really stand the sucky service in my area. I Have T-Mobile and have good coverage where ever I go and was wondering if the sim tray in the Sprint Htc one is Unlocked so I can just activate with my T-Mobile account and pop in a T-Mobile SIM card. If any one can please confirm this would be much appreciated. Thanks in advance.
No

I'm 99% sure it's a no. T-Mobile uses different radios from Sprint, I think AT&T and T-Mobile use the same radios, which is why you can use unlocked AT&T phones on T-Mobile.

It says the HTC one has been modified for sprint and it doesn't confirm that the phone supposes gsm on the sheet it only specifies CDMA and lte frequencies

According to some Sprint forums it is a world phone. It just isn't unlocked.
Sent from my LG-LS970 using xda premium
A world phone can have many different interpretations such as using a gsm network somewhere else or just roaming outside the us and we can all roam outside the us such as mexico which is domestic roaming and I think that is also considered a world phone since ur using it somewhere else
Sent from my EVO using xda premium
In the OP's case, a discussion as to whether the phone is SIM locked or unlocked on the One is completely moot because the Sprint variant of the device does not possess the GSM or UMTS/WCDMA frequency bands needed to operate in most of the Americas, including the United States. It only does GSM 900/1800 and UMTS 2100. In other words, even if it was unlocked for other companies' US GSM or UMTS SIM cards it wouldn't be able to get any signal in the US, or for that matter, anywhere in most of North, Central, or South America or in other parts of the world where the GSM or UMTS 850 or 1900 MHz bands are used.

According to this article, which I have linked several times on here in response to this question, the ONE on Sprint most likely has GSM 900/1800mhz capability. Which is the GSM most all of the world uses except for the US. That is why it is a "World Phone."

Partially true since this does not only apply to the US specifically. See my post right before yours.

Fixed that for you. You could not use it in the US.
but even by flashing a customized firmware once the phone has been rooted the phone is unable to manage others sim cards?
is there any change to remove the sim lock somehow?

Even if it was sim unlocked it wont work. Its a hardware limitation, not a software one. It cant run on the frequencies that North America uses for GSM.
It does run frequencies that we run here in the us. It supports 1900 and 2100 utms. 850 and 900 gsm. Both are used here in the us by at&t and t-mobile.

Isnt it hardware limited to a point where it cant operate on a 3g/hspa gsm data network? i.e. if you do sim unlock and take it to a gsm carrier you will not get anything over 2g/edge speed?
I know as the phone sits currently it will not work with AT&T but I was wondering if anyone had found a way around the differences in the networks to make it compatible. You people are pretty smart here so I'm sure someone has. :good:
There's actually a way to SIM unlock your Sprint HTC one to use almost every network using a SIM card but it will lack certain frequencies. U will be able to use 3g and certain locations will let u use 4g based on the frequency in the area.

I have heard of people doing this and still not being able to use AT&T because of the different frequencies with Sprint and ATT. If I can just SIM unlock the phone and use the voice I would be happy. But I have not seen where anyone has had any luck with getting AT&T voice to work on a Sprint phone. I will try it thought and see what I get!
Could you post a link to directions on SIM unlocking the HTC One? It would be greatly appreciated.
So I'm thinking about buying an unlocked moto x originally through Verizon but was used on t-mobile, my question is can anyone guarantee me that it'll work on att if I put my apn settings and will i get LTE ... any answer is appreciated

Ok... So you're thinking about buying an unlocked phone that was originally a Verizon phone but was used on T-Mobile that you want to use on AT&T? That is a bit convoluted, each vendor uses different bits of spectrum and a Verizon phone isn't a pure GSM phone such as AT&T or T-Mobile might have, I would be cautious, why not just get an unlocked AT&T device?
That being said, if it can be used on a GSM network like T-Mobile it should work on AT&T, the problem being that - as I said - each carrier uses different bits of the spectrum.
Save yourself the potential hassle and buy the proper AT&T model.
Yeah i am being cautious I'm passing on it thanks for the responses
