Hi, I bought my iPhone SE in June at Apple Store in US. I got a A1662 version - LTE was working fine. Recenlty I moved to Europe - Poland. Right now I do not have LTE, I tried 2 carriers. I checked http://www.apple.com/iphone/LTE/#iphone-se and I see that my phone supports band number 3 and 20 which is used by my carriers in Poland. I also checked BTS map around my place and they are 1800 MHz - Band 3. I do not understand why I don't get LTE. Is this version (A1662) not supported in Europe because of software restrictions ? Is it possible to unlock this LTE feature by making a Jail Break ?
