Sorry if this is in the wrong area (I didn't know if I was meant to post this in the spark fourms or in here because iPhone) Anyway, Whenever I try to activate 4G on my phone it acts as if it's trying to activate it but then it just ends up saying "3G"   Have checked and my area is 4G. My Samsung Galaxy S5 used 4G perfectly and 99% of the time it stayed on 4G.   My iPhone model (in settings) is MF356X/A but the back of it says A1530 (looked up online and apparently it's an Australian model)   Works perfectly fine on the Spark network and everything but like I said 4G just won't activate. Can someone help me please? I've tried resetting network setting, resetting my phone as if it just came out of the box and hard restarting; all with no luck.
