T-Mobil Shocking international charges! Nationwide

 I'm originally from Ukraine and live in USA  for 25 years now. It was my first triap out of USA- to Canada to see Niagara Falls.

I was aware that I cannot use my sell phone to call or text, so I did not! But I took it with me in car becouse it was 12 hours driving and I was planning to use 'hot spot " from my cell phone to activate WI FI on my tablet, so I could watch movies or brouse internet.

Ahother think I did, I looked on my emails, but not opening them a few times, not understanding that it was consider " internet" on my phone

First think I found on my phone next day in the morning was text from t-mobil warning me about using data. But since I did not make any calls and did not text or brousing internet, I was looking on it as a warning.

Next morning I receive another text from t-mobil with shoking amount on my bill for international data use and phone number to call them, so I called them. they said that charge will be on my next month bill ($369.00)

I turned my phone off and did not touch it any more until came back home in Illinois

I was upset about charge , I contacted t-mobil and they say that they can take off my bill $69.00 and I have to pay $300.00 plus my monthly charges on my next bill.

For a few last month I was complain to t-mobil about conection problems and disconecting calls problems, but it was never fixed and a few my friends sufering with bad conections to.

I was thinking to change my cell phone company for while and now I'm ready and doing it!
