  • Does The iphone 5s on Virgin Mobile support CDMA or GSM?

    so I'm going on a carnival cruise later this year and theyre talking about how their internet connection requires cdma or gsm to be able to use data and i just want go make sure my phone has it.

    Even if WHAT is in the Bahamas?
    You will have to pay international roaming charges outside of your home country. If it's a US Virgin Mobile iPhone, it's CDMA. If it's from another country, it's GSM.

  • Should I purchase CDMA or GSM iPhone for use in U.S. and Hong Kong/China?

    I currently have an unlocked GSM iPhone 4 that I bought in Hong Kong, and have been using it in the US through Straight Talk. I love having the flexibility of an unlocked phone when I travel. Unfortunately, the GSM networks in my area are pretty spotty, and Verizon's CDMA coverage is MUCH better. Not to mention the data speed is really slow.
    I'd like to purchase an unlocked iPhone 5s without a contract, and hopefully be able to use it on the CDMA network here in america, while still have GSM available for use when I travel back and forth to Asia.
    The pros and cons of GSM vs. CDMA iPhones are still pretty muddy for me, but it sounds like buying a CDMA iphone would be better for my situation because I could utilize both networks when traveling, and yet have the best speed/coverage in my current home in the US.
    Straight talk or Page Plus is what I'm looking to for carriers. Verizon's too expensive for me.
    Here are my questions:
    1. Does my choosing CDMA seem to be the best choice? Or are there any cons regarding purchasing CDMA that I've overlooked? I've heard people say there is no such thing as an unlocked CDMA iphone. My biggest concern is that I arrive in Asia and find that some CDMA lock prevents me from using any other carrier--CDMA or GSM. (Both networks are available there, btw.) I need to make sure I can use data and make calls when I'm there.
    2. If a CDMA iphone is the best choice for me, how do I purchase the right one without a contract? Apple store? Verizon? Straight Talk (do they sell CDMA iphones)?Canada? Ebay seems kinda risky to get an iPhone with the specifications I need.
    3. Does a CDMA iphone still have the slot for sim cards? That's how I've always switched carriers when in Asia.
    Thanks in advance!

    Thanks for the reply. I didn't know that StraightTalk disabled their iphone's GSM capabilities. Guess I won't be going there to buy one.
    A few follow-up questions...
    So is a SIM slot only used for GSM? This is something I never knew. I assumed for any network (GSM or CDMA) that a new sim card was the way you changed numbers/networks.
    I've heard people mentioning that they've been able to buy Verizon iphones and use them on PagePlus, but this information was a year or two old, so perhaps things have changed with the newer models/carrier contracts. Do you know of any people who have had success in using a Verizon iPhone 5s on the PagePlus network?

  • USB sync cable different for CDMA and GSM version phones?

    I recently ordered a USB sync cable for Iphone 4S from ebay. I want to know whether the USB sync cable for Iphone 4S is different for CDMA and GSM version phones? And if they are then what are the likely consequences if they are interchanged and used inadvertantly.

    All recent iDevices use the same type of connector/cable.

  • HT1414 Hi, I'm MODELS Iran is the iPhone 5 I need to download any type of cdma or Gsm?

    Hi, I'm MODELS Iran is the iPhone 5 I need to download any type of cdma or Gsm?

    CDMA and gsm are types of radio used by cell networks.
    They are not downloadable software.
    What is it that you are trying to do?

  • Will there be a universal phone with 4G/LTE + Current CDMA + Foreign GSM?

    This would be a true universal phone, yet I see none on the horizon:
    http://www.phonearena.com/phones/carriers/Verizon/upcoming
    This would seem an obvious great niche to fill...  So where is this phone?  Any ideas why this niche isn't being filled?

    While this sounds like a good idea, in reality it means now you have to find space for 3 radios and antennas in the same space you typically fit only one (or sometimes two).  And then tie them all together in the software.
    The biggest question is if there will actually be a market for this type of device, nothing gets built if it won't sell.  My opinion is the market would be very limited.
    I think that manufacturers will wait until LTE is established and working (reliably) on the Verizon network and then design phones with just LTE & GSM radios (no CDMA).  These will be the 'global' phones of the future (at least until the next technology comes out).
    I don't think we will ever see a CDMA/LTE/GSM 'universal' phone, there is just not a big enough market for it.  Just my opinion.

  • Greetings. Do you know if an unlocked Iphone 5S can switch from CDMA to GSM with a sim card, or if you have to choose one capacity or the other when you buy the phone?  Many thanks.

    Is this a Verizon or Sprint iPhone 5S?

  • Hello I want to Buy iPhone 5 CDMA and GSM open and I am in Yemen how to do it

    Hello I want to Buy iPhone 5 CDMA and GSM open and I am in Yemen how to do it

    NO it won't work in India because all the iPhones for sale in the USA are carrier locked to networks, so no they won't work outside the USA.
    There will be no unocked iPhones for sale in the US at the moment which is what you need, and anyway, if you purchased one in the US, there is no international warranty so there is nothing you can do.
    You will have to wait because it won't work in India.

  • Switch between CDMA and GSM Iphone 5

    Hi,
    I am wondering on the Verizon Iphone 5, can you switch between CDMA and GSM via a setting or is it still like the iphone 4s where you have to remove the sim card to switch back to CDMA?
    Thanks.

    A SOLUTION: cut another corner and insert the nano-SIM upside-down, and keep a SIM card ejection tool on your key ring or tape one to your phone's case or both.
    Adam, and anyone else who like us, was hoping that there were a software based method that would allow iPhone 5 users the option of toggling between Verizon (or other CDMA carrier) and whatever other SIM Card based GSM carrier we have inserted/installed into our SIM tray.
    For myself, I have a SIM card with the "Minutes" type of plan, specifically the minutes plan that gives 2000 minutes for $100, which is good for one year. This is my backup network. 
    Since I do not need a SIM for the CDMA network that I use as my primary network, my SIM slot is empty (I am not running LTE, only 3G).
    So, in order to be able to switch my handset from one carrier to the other, which would be most helpful in the event of a system failure on my primary carrier I can switch over to my "backup/gsm network; it would be very, very nice to be able to toggle between the two networks, (like in the old days where we could simply select either the 'A' {non-wireline} or the 'B' {wireline} carrier/network) by simply pressing a couple-few buttons.  It is funny to me to actually realize my old "Brick" phone actually had a feature lacking on my iPhone 5.
    This would have been great during hurricane Sandy when my Verizon service was (literally) dead in the water for several days.  And, there is always the possibility of a cell site going down on the primary network, again.

  • CDMA and GSM

    So in reading about the new Iphone 4s, it looks like it will support CDMA and GSM.  So to make it would not matter as much who your carrier is.  Or is it two of the same annttena so it can not switch between gsm and CDMA?

    Yes. It's a true "world phone".

    I'm not sure what you mean by this... The big reason for building a world phone is so that people who use a CDMA service in the very few countries that have them can put in a SIM card and get service in the rest of the world.

  • Upgrade question-W​hata CDMA and GSM

    I recently upgraded by blackberry bold to 6.0 and it as me a question.  I don't even know what it means so I said no!  I think this coded language is a bit assuming.  Here's the question.
    What does this mean ?
    "you have inserted a SM Card. Would you like our blackbery to automatically selct CDMA or GSM based on the network availability?"
    I think SM is my memory card. so what is CDMA or GSM and what would happen if I answered Yes!
    Will this end up costing me extra money?
    I hope someone can help me out, I spent 25 minutes wading through Support trying to get an answer.

    It's a routine question I get often on my CDMA devices, and unless you roam into another country, there's really no problem.
    If you're traveling internationally, you'll want to call your carrier anyway and set up an international calling and data plan.

  • What Configuration/Profile should use for Nokia 2280 ?

    I got a mobile phone Nokia 2280.
    In the box is written "Supports J2ME".
    In the Nokia website and java.sun.com, I can't find information about the configuration, profiles or APIs that i could use to write apps for this phone.
    Did anyone already write apps for this phone ?? Some tips ??
    I know. I write bad english ;(

    From the Nokia forum page for this phone it doesn't look like it support J2ME. It doesn't have the Java APIs section all Java phones have.
    But seeing as it's a Series 30 B/W phone, I'd try developing with standard MIDP 1.0 + Nokia extensions, possibly using the 6310i SDK (which is also Series 30 B/W).

  • Nokia 6275i cdma phone book transfer

    Can i transfer my phone book to a computer through pc suite
    in nokia 6275i cdma phone

    Try this
    Common methods of transferring data are:
    Transferring phone numbers via SIM card
    Transferring data via Memory Card
    Transferring data via Bluetooth
    Transferring data via PC
    Transfer via PC is the most effective, but it initially requires more effort to set up. You will need to download and install PC Suite software on your compatible PC and ensure that a number of variables line up, including PC Suite version, Windows operating system, and connection method compatibility.
    Transfer via memory card is the easiest method as long as both models support the same size of memory card. SIM card transfer is a simple method for transferring phone numbers only.
    Transferring phone numbers via SIM card
    SIM card transfer makes sense if you are only transferring phone numbers. Copy the phone numbers to your SIM card, remove the SIM card from your previous phone, insert it into your new phone, and store the phone numbers in your new phone's memory. For basic phone models without additional memory, the phone numbers may already be stored on the SIM card.
