as far as i know you have to wait the upcoming update.
You need to be on 4.3 for 4G.
search and read other thread on this forum, many people have your issue.
bye
unlocked UK do not have 4.3 .
it's not released yet.
yeah i tried them . couldnt find my phone on the sus one . thanks for replying
unbranded UK should receive .205 version which is the latest that should be avaiable soon.
for SUS if you are running on win 8 or 8.1 try compatibility mode and it should work
yeah im on 8.1 . ill give that a try . thank you 
anytime
"You need to be on 4.3 for 4G."
You don't have to be on 4.3 for 4G. It also worked on 4.1.2. Check the APN setting of your mobile network and whether or not you actually have the right to access 4G network since ome mobile networks are charging extra for use of 4G.
hi thanks for replying . yeah i got unlimited 4g on my plan with 3 .
