Yeah - I had the same thing happen earlier in the year and now again. It is hard to tell if these are truly government mandates taxes, or since I have "locked in" pricing on my phone and internet if these are other ways to raise the cost. Back in April or May I had a 50 cent increase on my cell phone and 20 cent increase on my 5G internet line (but the base plan price stayed the same). Now, I am getting another 50 cent increase on my cell phone, but no mention of anything changing on my 5G internet plan.
My thought is that if it is a governement tax/recovery fee, wouldn't we see an increase on AT&T and Verizon as well? Why just T-Mobile?
