Possible to use iPhone on GSM and CDMA networks?

If I have a SIM for one of the iphones that supports versions of both CDMA and GSM, could I actually switch between, say, Verizon in the US and foreign networks wihile overseas?

The only phones you can use on Verizon's network are ones that were originally sold as "Verizon" phones. This is true of, as far as I know, all CDMA carriers. Verizon will unlock the GSM side of an iPhone 4S for international use for their own customers. Other CDMA carriers have other policies. The Verizon iPhone 5 and later are unlocked and will work on any GSM network.
An unlocked phone purchased from the Apple Store will not work on a CDMA carrier.

  • I bought a used iphone 4 (gsm) and it was locked on an icloud account i asked the old owner to remove the device from his devices list on icloud and he did but the iphone is still asking to be activated on his icloud account. any help please???

    If it's still asking for the seller's Apple ID and password, then he most likely did not actually remove the iPhone from iCloud. If the problem persists, return the iPhone and get your money back. The seller can figure out the problem and resell the iPhone later.

    Can I use iPhone 5  GSM AT&T in US, Europe and Japan

    Yes  on roaming but only on 3G
    However if you want to use a local sim only an unlocked iPhone will work but only 3G again
    The US LTE bands in US shipped iP5  will not work in Europe or Japan
    @serdriver There is NO CDMA in Europe for reference and OP is talking
    a GSM AT&T

  • Why not to be unlocked iPhone working with GSM and CDMA/LTE in one device?

    why not to be unlocked iPhone working with GSM and CDMA/LTE in one device?

    I'll explain, does Verizon unlocked iPhone 5s work with CDMA networks (with SIM or without SIM), and if I travlled to another country that provide GSM operators, does the phone will work with GSM SIM normally?

    I'm copletley unhapy with ISO 7 Im using iphone 4 GSM it's so slow now how to downgrade back ???

    Thanks a lot for the link. I'll try out if that will help to speed up my phone.
    However, there has to be a possibility to downgrade to ios6 - otherwise the guys from Apple wouldn't have advised me to do so.
    Beside of all the problems I have withe the new ios it also looks childish designwise and lot of of things like handling was much better with ios 6.

  • HT3939 Gsm and cdma inquiry in Middle east

    which iPhone model support the both gsm and cdma  in middle east ??

    Yemen is not listed as there are no LTE networks, as per this Apple Doc.
    Also that Apple do not sell iPhones in Yemen, officially.
    Moreover, CDMA iPhones are for a specific operator whereas GSM unlocked iPhones are available.
    Please remember, Warranty and out-of-warranty services of iPhones are provided by Apple in the country of sale only.

  • Is it possible to use both an ILB and an ELB (listening on the same port) in the same Azure cloud service?

    I'm building a test Lync deployment on Azure; yes, I know this is not supported, hence "test".
    Lync Front-End servers expose two set of web services, one for internal users and one for external ones; they listen on different ports (443 and 4443) on the same servers; when external services are published, you need a reverse proxy or a port forwarding
    in order to map port 443 of a public IP address to port 4443 of the Front-End server(s). When you have multiple Front-End servers in a pool, you also need to load-balance them.
    So, a typical Lync deployment looks like this:
           Internal users
                     |
                   443
                      |
              Internal LB
            192.168.0.20
            443         443
              |               |
       Lync FE 1     Lync FE 2
    192.168.0.21 192.168.0.22
              |               |
          4443        4443
              External LB
           Public IP Address
                     |
                  443
                     |
           External Users
    This should be easily replicated in Azure, as it supports both external load balancing and internal load balancing. They are even supported together in the same cloud service, so this configuration should be easy. However, it looks like "should"
    is the keyword here.
    After creating the external load balanced endpoint (which listens on external port 443 and forwards to port 4443 on the servers), I'm trying to create an internal load balancer and add internal endpoints to is; however, while the ILB can be created successfully,
    adding an internal endpoint listening on port 443 and forwarding to port 443 on the servers fails miserably, with an error stating that port 443 is already in use by another endpoint:
    Update-AzureVM : BadRequest : Port 443 is already in use by one of the endpoints in this deployment. Ensure that the port numbers are unique across endpoints within a deployment.
    For reference, my commands are:
    Add-AzureInternalLoadBalancer -InternalLoadBalancerName "LyncILB" -ServiceName "LyncFrontEnd" -SubnetName "LabSubnet" -StaticVNetIPAddress 192.168.0.20
    (This completes successfully)
    Get-AzureVM LYNCFE1 | Add-AzureEndpoint -Name "Https-Int" -Protocol "tcp" -LocalPort 443 -PublicPort 443 -LBSetName "HttpsIntLB" -DefaultProbe -InternalLoadBalancerName "LyncILB"
    (This fails)
    The existing external endpoint is configured as such:
    Get-AzureVM LYNCFE1 | get-azureendpoint
    LBSetName : HttpsExtLB
    LocalPort : 4443
    Name : HTTPS-Ext
    Port : 443
    Protocol : tcp
    Vip :
    ProbePath :
    ProbePort : 4443
    ProbeProtocol : tcp
    ProbeIntervalInSeconds : 15
    ProbeTimeoutInSeconds : 31
    EnableDirectServerReturn : False
    Acl : {}
    InternalLoadBalancerName :
    IdleTimeoutInMinutes :
    LoadBalancerDistribution :
    The error doesn't even make a lot of sense; the external load balancer listens on a public IP address, while the internal load balancer listens on a private IP address in the internal network; there
    shouldn't be any conflict here... however it looks like there is one instead.
    Why doesn't this work? Am I doing something wrong, or is Azure networking just being silly as usual again?

    Hello Massimo Pascucci,
    The issue that you are facing when creating an endpoint with internal loadbalancer is the limitation of not allowing same ports to be listening under a single cloud service. This reason for this is that there is a limitation of only one private IP (Also
    known as the Internal load balanced IP) per cloud service.
    There is also a limitation on the Internal load balancer more than one port to be published per load balancer:

    I believe because you migrated from a Nokia to an iPhone you need to register the Bn phone number with your Apple ID so it can be used for iMessage. The Pn number seems to be the only one registered

    Manage your Apple ID and see if that does the trick

  • Is it possible to use an exact phrase and a wildcard in the same query

    I am building an address finder, and i have an option where the user can enter part or a full uk postcode. There is a ctxcat index on the address field. I am having a problem searching for part of the postcode, if i enter 'ZZ1 2*' it finds all ZZ1 and all house number 2's if i enter ' " ZZ1 2"*' it fails with an error, is this a bug or is it not possibl to use the exact phrasing and wildcard at the same time.
    If its not possible can anyone suggest another way round this query.
    Thank

    hi,
    in my table i have a column called address,
    these would contain something along the lines of these 2 records.
    10 high street anytown ZZ1 3ZZ
    3 bridge street anytown ZZ1 8ZZ
    If searching on the postcode, the user may enter ZZ1 3 at the moment this would bring back both records, the first one from the ZZ1 and the second one from the house number 3. however if ZZ1 3 is entered i am wanting to just search on the postcode, so it would only match on the first record. so i would like to put the double quotes round the "ZZ1 3" to match on the exact phrase, but then no records come back because of the two letters after the 3, this was why i am asking about the wildcards after the exact phrase ,atch, so it can match the exact phrase of 'ZZ1 3' but then allow any characters after that.
    hope this explaings my problem a bit better.

    I am unable to access intranet on my MacBook Pro 13" with OS X mavericks. Is it possible to use files on the Local Area Network? I use the files on the Local Area Network on my windows computer by typing in the I.P address in the library. Kindly guide me how i can use these files stored over the Local Area Network.

    I disabled GateKeeper's automatic blocking of unrecognised developers, and so I was able to install the driver.
    The Mobile Connect program is now installed, but the computer still does not recognise the modem.
    I also borrowed a USB hub from a friend and it didn't make a difference.
