Can I convert My galaxy y GSM into CDMA

nope,
thats a hardware thing,
you can't change the radio of your phone

In your dream maybe you could lol

or get a new phone
:highfive:

Yep u can... Change your network hardware things with galaxy y cdma...

Thats the most impossible thing since its the cellular radio inside the phone and it uses a diffent frequency range
this post is potato friendly

Yes you can and radio has nothing to do with it. I worked at a gsm cellphone company. You can use a cdma on a gsm network. I also worked for a cdma.. yes you can use a gsm on a cdma network. Though it has to be hacked and changed. I'tl void your warranty but yes it can be done.
You have to search hard for it and again radio frequency has nothing to do with it so that is bull.
The phone in part was a factory bought unlocked gsm asus zenphone 2. They wanted to use there unlocked phone on a cdma network knowing it was a gsm.
I told them it's not possible. Sorry.
Well they came back a few days later same phone. I checked the serial ect to make sure. It went from gsm to cdma. He said he got it sent away by someone online who fixed the phone.
Entered a simple from our company and we'll it worked. Not the best signal 3g at best but it worked. He woudnt tell me how he did it other then it cost ALOT.
But it can be done iv seen it in person.

I'd be very interested to learn more if anyone has additional insight. It occurs to me one might be able to swap the radio unit from a donor device if you want to make a "permanent" switch...
On a side note, is it just me or are new tablets coming out with lower specs than they did a few years ago? I'm looking to get a new Tablet, compatible with Sprint. All their offerings are way underspec'd compared to my Galaxy Tab Pro c2014. It also baffles me that nobody bothers to offer a dual radio option, especially considering how (relatively) big devices have become. How much could a radio unit cost at quantity? I suppose the carriers are commissioning the designs to be best suited for their service alone?

Radio Frequencies on mobile phones reply
May be that device was a gsm and cdma when manufactured; and maybe the calling company that sold it first demanded the manufacturing company to lock it on a gsm. It seems that the online guy, who made it work on a cdma, had to only inlock the feature and not hack it’s hardware radio frequency to get it work.

what about honor play COR-L29?

Need help on carrier change

Hello everyone!
It's my first post here, I'll try to make this simple and understandable.
I've got an HTC Vogue (obviously), unlocked it last week, installed NFSFAN's ROM, everything is fine. The phone is currently out of plan, which means my contract ended. I want to change carrier (currently on Bell's CDMA), but I don't know where to start. Basically, I want to go with Fido. I read alot about PRL and those ESN, CDMA Tools, etc... Just want some help and small how-to on changing the carrier from Bell to Fido. I have another phone which is with Fido, (LG Neon). Can I get the carrier informations from this phone with some software/hardware or just common sense method (like calling them). At the store, they told me they couldn't get my phone on their network because it was with Bell, but I know there's a way of doing it.. There's a way for everything, and this must be easy.
I qualify myself as moderately advanced in computer skills, so don't be shy to share even the most complicated methods of doing it!
Bump. No one did this before till the Touch Vogue was released?...
I sent you a pm about this a few days ago.
Bell=CDMA
Fido=GSM
Can't switch.

Somewhat true up until last year. New phones that use SIM cards for Bell/Telus HSDPA network are now interchangeable with Rogers via some handiwork.
But yeah, the Touch is, well, a little bit older no SIM cards for her.
You should be able to switch to another CDMA network though, like Sprint (in the US) or Telus.

But HOW?

Nexus One lives on as Google's official developer phone!!!

http://www.engadget.com/2010/08/05/nexus-one-lives-on-as-googles-official-developer-phone/
LONG LIVE THE NEXUS ONE!!!
Only problem, at least for me, is that it's the T-Mobile band version.
But it's still awesome nonetheless.
I am glad I am with tmobile is tbis phone going to be the one they gave out to developers with security off or will it be like the retail version

I bought an AT&T version before they stopped selling them, and on the slip that came with it it says
GSM 3G 850/1900/2100MHz
If i'm not mistaken, what is "the 3 UMTS Bands 900/AWS/2100" mean.
Does this phone not cover all bands? It's quoted to be carried independant.
There are two different nexus ones out there. Each one is compatible with both AT&T and T-Mobile voice and data frequencies. BUT, if you get the T-Mobile banded model, then when you put an AT&T sim card in it you will only get Edge speed internet. The difference between the two is 3g connectivity. The really ****ty and annoying thing is the chip that is in the phone is supposedly capable of all GSM frequencies and all 3g frequencies but the phone is missing the correct ancillary chip to activate them all. So they made two different ones. I would bet that the American carriers weren't hap py about having a phone that could be taken from one provider to another and put their foot down. Just my theory though.

How compatible is the atrix with T-Mobile?

Sorry if this has been answered but I'm on the xda app and can't search. I'm thinking about getting this phone and unlocking it to work on T-Mobiles network. How cross compatible is it? Will it work with the T-Mobile "4G"?

Nope, you will only get 2G (EDGE).
t-mobile and at&t use different 3G frequencies, so if you unlock it you will only get EDGE speeds. Not worthy IMO, you have lots of options in your country, i would recommend to wait for the samsung galaxy s II phone.
Will work on the network but data will be at Edge speeds, not 4G.

On the new Nexus S - if you run out of internal storage - what size memory card can you add? Oh, wait they left off the SD card slot on that model. But those super AMOLED screens are really easy on the battery right? Oh wait, if the screen is black they use less juice but not otherwise.
Sorry, had to pick on you. Suffered with the captivate for 8 months..... yeah i drank the Koolaid - now i know better - but samsung sure can spin it.

Just ignore him, hes been trolling all over the Atrix forums. The gyroscope in his phone apparently makes his keyboard so fast that he cant use punctuation.

Inspite every where they said you'll only get EDGE , I Saw one guy saying he got 4G on simple mobile which uses the TMO towers sometimes (both have same frequencies)!!!
I bought the ATRIX on TMO and for 2 days now only EDGE

nowhere do they say you can use an att phone on t mobile 3G. it's been known for years that their frequencies are different and incompatible. you just didn't do your homework before purchasing.

That code process is to unlock the phone to enable it to be used with networks other than AT&T. But that doesn't get you data speed any faster than 2G/Edge using an Atrix on T-Mobile's network.
I'm a little confused here. You guys are saying that the Atrix will only get 2G/EDGE speeds on TMobile because the frequencies are different.
I am currently using the Nexus One.. how is it that I'm getting 3G speeds with a phone that is compatible with both AT&T and TMobile then??
Doesnt this mean that the Atrix should be able to get 3G speeds as long as it has the appropriate software? or am I not understanding something..
There are 2 kinds of nexus ones.. one with AWS bands (tmobile) and one with the regular 850/1900 (ATT). That's why you see them work on both tmobile and att. But a single device won't work on both bands.
It is a hardware issue. No software flashing will be able to fix it. If you bought the wrong one then you're stuck with it.

False. There's not a chance in the world that is true. T-Mo USA and AT&T use mutually exclusive bands. No carrier-branded phones carry both bands. The only modern phone that carries bands necessary for 3/4G on either network would be the upcoming, not-for-sale/developer-only Nokia N950.

The Nokia N8 and E7 also have the 3G frequencies necessary for both At&t and T-mobile, as well as Europe/Asia (850/900/1700/1900/2100). However, I agree with you that no At&t/T-mobile branded device carries all the needed bands.

Ah, I see. I didnt realize that there are 2 types of the Nexus One.
I had assumed that since they are not branded by any carriers that they were all the same device.
Thanks
I was really hoping to have my TZones internet plan, which runs at 3G speeds on the Nexus, run on an unlocked Atrix but that doesn't look possible.
Are there any phones newer than the Nexus One that will work with Tmobile 3G and are unbranded by Tmobile?
The branded Tmo android phones lock out my Tzones.

Here's a list of phones that will work with tmobile 3G. Take your pick. You may have to source it from somewhere else if you wish to buy it unlocked and unbranded.
The Nexus S is unlocked and unbranded even if you get it from tmobile. But since you are coming from the Nexus One, it is up to you if its worth the upgrade. Other than the Nexus S, have a look at dual core phones.

Atrix on t-mobile
i am currently running atrix 4g on system version 4.5.141 and android version 2.3.6.. I am rooted and have and unlocked boot loader. I also got the unlock code for my phone and it was successful and i am now running T-mobile sim chip i am only getting the Edge .. I have a thought as if you could change the phone frequency settings with sqlite editor i mean if you can disable the entitlement_check to enable theathering with AT&T's 2gb plan then we should be able to figure out how to change the frequency ratings of the phone to be able to run on t-mobiles 4g ... I wish that someone with a little more Knowledge could help out with this..

Hd2 on at&t

I have a hd2 tmobile usa version, i need a At&t friendly Nand rom. Whats the best rom out there for At&t????
Sent from my Desire HD using XDA App
as far as I know any NAND Android ROM should work on AT&T as it is not the ROM that controls this but a combination of you sim card, APN settings, and you having your HD2 sim unlocked. Wait for more replies though as I do not use AT&T and it might actually be a ROM out there that has certain things adjusted for AT&T, but what that might be I do not know.
This is true, the ROM does not control the radio. There are methods of flashing the radio to a different version, one that may work for the AT&T 3G bands. I am looking them up, but that is how you would flash the device to change the radio.
Hardware wise, the GSM module does support all world wide bands but what makes then different from one HD2 from one carrier ot another is the firmware version that is used in the phones that make them work on the network's bands. Correct me if i am wrong though.

Untrue my friend, the T-Mobile HD2 only supports the bands used by T-Mobile for 3G. If you sim unlock the T-Mobile HD2 you can use the device with other carriers but you will only get Edge for a data signal as the hardware only supports the T-Mobile 3G bands. There is a model of the HD2 that supports a different 3G band the same ones AT&T uses in the US, it is the Australian model that Telstra a Australian cell carrier released as they use the same bands as AT&T. go to "Official HD2 T9193 (Telstra 850Mhz) Discussion Thread" and you can learn more about it. I also saw your other post in another thread about trying to help your friend out getting 3G on his HD2 using AT&T. Unless he is willing to buy a Telstra HTC HD2 T9193 or have his T-Mobile HTC HD2 T8585 worked on to switch out the hardware for the hardware in the T9193 then he will never getb 3G with AT&T.
Just to answer your question, every rom is an AT&T friendly ROM, meaning, they'll allow you to talk, text and surf the internet.
What you DONT have is AT&T 3G on your tmous HD2. You'll be stuck with EDGE speed.
Thank you all 4 your help,greatly apreciated!! I'm in puerto rico where tmobile is still on Edge. But for some reason tmobile is still alot faster when it comes to receiving & sending MMS than At&t on this phone. Currently using Coredroid 1.5
Sent from my Desire HD using XDA App
its interesting they would use different hardware GSM modules for the slightly different models. I would think the radio firmware version woudl take care of that. Thanks for clarification. I assumed that all GSM modules would be built the same way.
Sadly they are not, this in my opinion is just cellular carriers trying to keep you locked to their networks cause the know most people don"t want to have to buy another device when changing carriers if they already have a good device. So they make it were branded devices can only utilize high speed data with it's intended carriers network. I think this is unfair to consumers, but again just my opinion.

I think there is technical reason. The various carriers have very different technologies. Even AT&T uses a different 3G network than T-Mobile, despite the fact that both are GSM. Sprint and Verizon use non GSM technologies that are even more different. When a device manufacturer makes a certain model, there is only so much room inside, and unless one wants a really thick and heavy device, a choice has to be made as to which hardware goes into the phone.
I'm not saying that they don't want you to stay on their network - they do, which is why they have those 2 year contracts in exchange for buying a discounted phone. But I don't think that is why the hardware is different.

[Q] Possible to Unlock?

Hi I wanted to buy this pone from amazon, but the thing is that I would buy the sprint versión with no contract and I don't live in the US, so my question is, can I unlock this pone to use it with any other company? like Movistar? I read that the pone was GSM so I thought it would be posible, however I won't take the risk of paying 590 dollars for a pone that I can't use, thanks

The ONLY part about sprint that is NOT CDMA is LTE which the sim card slot is LOCKED to sprint.
They MIGHT be a fix but right now there is NOT. Some of the older phones like the Moto Photon its not LTE but its a world phone and people could flash a few things and make it work, But only EDGE in the USA anyway.
But as of right now and problay for a while its NOT going to work.

I expect Sprint will provide a method soon to unlock the GSM and UMTS functions in the phone to be able to use it internationally. However, I don't expect the GSM and UMTS functions to operate inside the US. Sprint has always disabld them on GSM capable Android and iOS devices it sells.
I don't see why it wouldn't work for you as long as you can get it unlocked.
Sprint is not going to unlock it for you unless you are a long time customer or have the phone with them for 90 days.
hyelton is completely wrong though.. the sim does authenticate lte on sprint but also acts as a gsm sim internationally.
you can also remove the sim and insert any international sim once unlocked providing the carrier uses the correct bands.

You are all kinds of WRONG.
Sprint's GS4 is fully capable of voice and data on international GSM/HSPA+/UMTS 850/900/1900/2100MHz networks. You have to request Sprint to unlock your phone's sim (or find a work around if you're not a Sprint customer), but once unlocked you can pop in any international sim and it will WORK JUST FINE on international GSM networks, they don't have to support LTE. Heck the only thing preventing the SG4 from working on US GSM networks is Sprint locked the Sim from using USofA GSM carrier sim cards.
As long as the OP can get their Sprint SG4 sim unlocked, they can pop in their international sim and use the GSM in their country NO PROBLEM like any other GSM phone.
SO ONCE AGAIN, Sprint's SG4 has a fully functioning GSM modem that supports international carrier GSM/HSPA+/UMTS 850/900/1900/2100MHz bands!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You would think someone with almost 2,000 posts and who made a statement like "I KNOW my Cellular Networks!" would know better. Do yourself a huge favor and actually know what you're talking about before you go spouting off again, because you really made yourself look like an ignorant fool.

Well YES you can easily use your phone overseas, But it was POSTED in the Sprint Forum which is ONLY in the USA and in which using it does NOT apply in the USA. And to get the phone unlocked I`m not sure if a regular unlocking company would be able to do it someone with a sprint account would and it would be MUCH more trouble than just to pick up a ACTUAL GSM carriers Version of the phone.( I should had just said that to begin with) Its VERY pointless to TRY and want to use the sprint Version when they are SEVERAL OTHER varrients that are GSM they could have got to use.
EXCEPT... the op specifically said they wanted to purchase it from Amazon America to use on their country's GSM network.
Why they want to do that? WHO KNOWS, maybe it might be cheaper doing it this way, but that is what they want to do and despite all your unnecessary wrongful information, the OP can do what they asked as long as they can get the sim unlocked.

I sell on Amazon and Most people wont ship out of the USA on Amazon. Mostly only Candia but Ive tried ordering a lot of things overseas and 90% I cant as they wont ship here
Amazon sells the Sprint for $599 this is probably why. I bought mine at Best Buy and had them price match Amazon for that price.

Looks like everyone here is an expert in this matter but so far haven't seen a single link to reputable sources... OP call sprint international department and get answer straight from the carrier (888) 226-7212
Even IF the phone is capable of being used in GSM bands internationally, you would have to get it unlocked by sprint and they change policies all the time so just call..

I got my phone unlocked for international use. I contacted sprint international services. I was initially told that you have to be activated for at least 90 days before they could unlock the phone but would forward my request to some department. After one day I got a email that my phone has been unlocked.

Yea.... but it ONLY works internationally AND you have to be a sprint customer.
The POINT I have been trying to get across is that people need to understand Sprint is a CDMA carrier and ONLY relies on GSM for LTE. I think what people think is that they are solely a gsm carrier like most of the world is but its NOT
