I bought a new unlocked S4 from Vodafone and have switched to Telecom now.
Everything is working fine however it won't connect to 4G LTE.
Under "Network mode" there are only three options and none with LTE.
I have taken this into both Telecom and Vodafone shops, and they didn't know what the problem was.
I've got a 4G Telecom sim, that works on 4G in a friends phone, so it's definitely to do with the S4 device.
Details about my phone are:
Baseband version: I9505XXUEMK9
Build Number: JSS15J.I9505XXUEMK9
Is there an easy way to fix this problem?
