Hi, I want to buy an iPhone in the US in the next few weeks to use here in Ireland, as it is about 200 euro cheaper. However I'm getting confused on the model numbers and what I need... Let's just assume I'm buying the unlocked version and the regular iPhone 6. Also bear in mind that any CDMA version bought unlocked will be unlocked to all GSM carriers so choosing the Verizon/T mobile/AT&T versions is irrelevant as they're all the same model number, only the US Cellular/Sprint model is a different model number. However, correct me if I have this wrong. In Ireland, they only sell Model A1586 (GSM), which is the Sprint/US Cellular model. It has extra LTE bands, but as far as I'm aware (read: what I've googled and wikipedia tells me) the LTE bands for Ireland are 20, 8, and 3, with the frequencies 800, 900 and 1800 Mhz, respectively. These bands are in both the Verizon/AT&T and Sprint versions of the phones. http://www.apple.com/iphone/LTE/ Essentially, Model A1549 and Model A1586 both have the LTE bands I supposedly need. http://en.wikipedia.org/wiki/4G#Ireland So, tell me, can I buy Model A1549 (GSM) (or the CDMA version) and use it here no problem?
