razer phone 2 LTE issue (vodafone NL)

Hello everyone,

I have a problem with my razer phone 2, the LTE function is not wrking properly. i've fiddled with the prefered network types but those do not seem to work, also put in the APN for vodafone but also does not work already had a new sim, it does, sometimes, connect to LTE but then i don't have any internet. 3g works fine but problem is vodafone is cutting of 3g in february and im still on a payment plan for over a year. contacted vodafone but they are sending me to Razer. put in a ticket over a week ago, no reply. i really need some help here

regards,

Bart
