I have a family plan. I found how t-mobile can take your money without your permission:
- T-mobile sent to your kids/grandma/grandpa cell message like "If you want more gigabits please click Yes!". Nobody dislikes more gigabits! And yes, of course, your kid/grandma will click "Yes!"
- You kid/grandma click Yes and wow: you data plan payment for the kid/grandma's line became $40 instead $30!
- Yes, t-mobile just inform you by sms your data plan was changed, but did you read carefully any sms? I'm not because I don't like commercials and annoying services sms.
My question is: if you are an account holder and you pay bill for all your family lines how to possible your bill may be increased even without your permission?
I'm working in advertising last 20 years and this is just marketing tricks created by "smart" t-mobile management.
I found the trick after 6 months I paid for highest data plan on one of my family line. Of course t-mobile support doesn't return my overpayment money for the half year.
The method for upgrade data plans may be work if t-mobile will be sent you message with question: "Are you agree data plan for the line xxx-xxx-xxxx will be changed to new plan?" Yes or NO
