The sticker and the firmware (Optus AU) both say it is an E5186s-61a which is the Band 28 model but I don't get 2degrees B28 on it at home. It has been suggested that maybe it supports part of the band but 2D where I am is on an extremity of the band which may not be universally supported. Pass. It worked fine in town on all the networks on 4G and works fine here on 2D 3G and the others 4G but they have multiple bands in use here.
Make me an offer really. I paid $200ish for it but it's no use to me now.
