I was with T-Mobile for 6 years
I received a offer via email stating if I use Mint.The limited offer I could have unlimited data for 15.00 a month for three months I then let the representative know ok let's do it I'll prepay the year. Once I activated my phone with Mint my said I only have a allowance of 5 GB per month. When I called to get what I was promised "unlimited data" they told me because I prepaid for a years plan Mint could not honor first time customer offer of unlimited data. I had to come out of pocket a additional 179.00 for unlimited data. What a shame they did not offer to prorate or only have unlimited for three months so I can try their services as solcited. I will add more stars when i get compensated for breaking their limited time deflation promise to their customers. This whole process took 7 days to finally activate my phone and two charges. Not so advanced for today's technology. Very simple to make custom fixes to plans without some much back and forth and telling my story with every rep I speak to.
