So I upgraded to os 7.1 during the week and thought I'd phone vodafone uk because I had read that you needed to phone them to activate the mobile hotspot option so I did and spoke to a representative... Turns out he had no idea what I was on about and said I must have a faulty handset. Anyone else phoned them and got it activated? Or is it not available for uk or vodafone?
Works for me. here's the screenshot. I upgraded my 9380 into OS 184.108.40.2066 from other carrier since on Telkomsel there's no available update, I just delete the vendor.xml file. And everything is fine till now. I checked and it costs more on the data connection. Perhaps I have to apply for the other data plan that covered all the data connection.
(Sorry, forget to capture when the other devices connect to the Mobile Hotspot)
