has anyone managed to use an unlocked Galaxy S4 I9506 with LTE/4G on 3UK (three.co.uk)?
When I use a 4G 3UK SIM in a Galaxy Tab 10.1 (2014 Edition) I can see a Network Mode of WCDMA/GSM (auto connect), as well as WCDMA only and GSM only.
When I use a 4G 3UK SIM in a Galaxy S4 I9506, I can only see 3G/2G (auto connect) and 3G only modes - no option for 4G/LTE.
If I use a Vodafone or EE SIM in the same I9506, then I see Network Mode options for 4G/3G/2G (auto connect), as well as 3G/2G and 3G only.
Any advice on firmware/baseband versions gratefully received.
Thanks in advance
