What data are you getting? Only Edge(2g) or are you able to pick up umts or hsdpa 3g?
Also,just to make sure were on the same page,are you looking of "old" 4g(hspa+) or are you looking for LTE?
Its possible you may need an apn change,has your carrier walked you thru a setting that supports your missing 4g?
