Hi, I bought BV8000 Pro two days ago and i'm using it in UK with LYCAMOBILE network. I am not able to connect to mobile data network. I've tried 4G and 3G both and none of them work. I am guessing LYCA mobile's bands are not compatible with this phone. But, even if want to switch, i am not able to figure out which other network provider in UK is compatible with this phone. EE, O2, Vodafone, Lebara... Which one should i use?
