Thread: iPhone 5 on Sprint. Can it be used on Cincinnati Bell?

  1. #1
    Default iPhone 5 on Sprint. Can it be used on GSM networks?
    Help me out here guys and girls. I have been playing with iPhones for some time but the 5 is new to me.
    A friend of mine has an iPhone 5 he purchased on the Sprint network that I would like to use on Cincinnati Bell (GSM network, same as T-Mobile).
    Iíve been using iPhone 3Gís, 3GSís and 4ís for years but I havenít messed with the 4S or the 5 yet.
    Is it possible to unlock a Sprint iPhone to be used on a GSM T-Mobile type network and what kind of problems should I expect to run into? And what do I need to do to unlock it? He claims to have replaced it so it should be off contract. AT&T iPhones are easy to unlock so long as they are off contract but Sprint is a new adventure for me.
    Any help is, as always, greatly appreciated.
    Thanks in advance,

    I found this on the Mac forums. Sheds a little light on the subject. Would seem its almost impossible to use a Sprint/Verison iPhone 5 on the USA GSM networks. I have heard the unlock is very difficult and expensive and it leaves you with other issues to deal with on the texting side of things. Guess I'll be selling and looking for an AT&T version of the phone.

    "In deciding to go with blazing fast LTE capability in the iPhone 5, Apple was forced to release three different devices to meet compatibility with different LTE network standards worldwide.

    The A1428 model iPhone 5 is the Canadian and US AT&T network GSM iPhone, including broad support for UMTS/HSPA+DC-HSDPA (frequencies 850, 900, 1900, 2100 MHz), GSM/EDGE (frequencies 850, 900, 1800, 1900 MHz), and LTE bands 4 and 17.

    The A1429 iPhone comes in two different flavors, one CDMA and one GSM. The GSM model is designed to support LTE in Asia (including Hong Kong, Japan, Singapore, and South Korea). This GSM iPhone will also work on LTE in Australia, Germany, and the UK on bands 1, 3, and 5.

    The CDMA version of model A1429 works on Sprint's and Verizon's LTE networks in the US, along with the KDDI network in Japan on bands 1, 3, 5, 13, and 25. The CDMA version also supports GSM bands, making the CDMA iPhone 5 compatible with GSM networks. However, the CDMA A1429 will not support LTE on GSM networks in the US.

    Full specs from Apple:

    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)"
