Bluboo XFire phone - 4G issues and internet settings

I just bought a Bluboo XFire and I'm trying to get internet 4g or 3G working. I've tried all the settings on Straight talks website and some on XDA's site. I just wanted to know I'm not alone on this. I've tried different setting. I think it's a rom version issue. But really not sure. Has anyone else had this issue?
