Default Slow 3g speeds?

I did a speedtest on 3g with my phone and compared with a iphone 5 also on 3g. My phone got .4 mbps and the iphone got over 1 mbps. Im just speechless here, since this makes no sence. 4g speeds are comparable with other devices on 4g, its just 3g thats the problem. Would it matter that im on cyanogenmod 11? Thanks
