What were you paying before? How much did extra did those 2 GB increase the data portion of your bill? Are you on the More Everything or Verizon Plan? If you are on the Verizon Plan, did this addition of 2 GB mean you changed from the More Everything to the Verizon Plan. If you didn't change plans but just changed your data bucket, your taxes should not change. If you changed from the More Everything to the Verizon Plan, your taxes could have changed because the line access fees for those 2 plans may be different. No one on here can answer your question without more information.
