There has been a verizon baseband update you can check about that...what is your carrier version? is there "Verizon 13.1" in the carrier field?

  • jjftexas Level 1 Level 1

    I'm a bit confused.  If I'm not mistaken, All Verizon phones, including the iPhone, run on CDMA not GSM.  Therefore, you can't expect to make calls on a GSM network in India with a CDMA handset.  Read this article about CDMA and GSM here - It's a simple and basic description of a Verizon iPhone but I'll copy out of the article what I'm talking about:

     

    Can I use my existing AT&T iPhone 4 on Verizon's network?

    Unfortunately, the iPhone 4 that is designed for and sold by AT&T will not work on Verizon Wireless' network. The reason is that the AT&T iPhone is based on a technology standard known as GSM, while Verizon Wireless uses a technology standard called CDMA. These are different technologies, and they are not interchangeable. So if you want to use the iPhone on Verizon, you'll have to purchase the new CDMA iPhone 4 designed specifically for Verizon Wireless.

     

    Again, you can't use a CDMA phone (Verizon iPhone) on a GSM network.  This is one reason that the Verizon iPhone is not a good world phone candidate as most networks outside of the USA are GSM (I believe).

    Hope this sheds some light about why your phone isn't functioning on a GSM cellular network.

    Starting with the iPhone 4S, unlocked CDMA iPhones can be used on GSM, 3G, and some LTE networks.  Verizon iPhone 5s should all be unlocked.

     

    Are you sure the SIM is active?  Was it cut down to nano size?  That may have damaged it.

  • Parin11 Level 1 Level 1

    When i Put Verizon Sim it Shows Carrier 13.1

     

    Again when i put other Sim it Shows 13.0

     

    it means the Verizon SIM is Getting Updated

  • acx12345 Level 1 Level 1

    but which sims are able to connect to network fully i.e fully functional...calling, edge data

  • diesel vdub Level 7 Level 7

    Read the specs:

     

    • GSM model A1428*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 4 and 17)
    • CDMA model A1429*: CDMA EV-DO Rev. A and Rev. B (800, 1900, 2100 MHz); UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5, 13, 25)
    • GSM model A1429*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5)

     

    On GSM, it should work.  ON UMTS/HSPA+/DC-HSDPA it will not work on the Verizon model because of a lack of hardware support on those frequencies.

     

    This is the problem that occurs when trying to use a device on networks it was not designed for.

  • acx12345 Level 1 Level 1

    Which SIMs are able to make calls??? Technically all of them should be working fine as the GSM bands are same for both at&t and verizon versions and these are also the same on iphone 4s. Only the LTE bands are different.

  • acx12345 Level 1 Level 1

    Read carefully, the UMTS/3G/HDSPA bands are the same

  • acx12345 Level 1 Level 1

    Parin i would recommend you to do a restore via itunes

  • diesel vdub Level 7 Level 7

    Ah, my mistake... I was misreading something... just too many numbers in the same spot.
