T-Mobile may be changing its data plans come May 22. An internal screen shot has shown its face showing four different data allotments: $10 for 200MB, $20 for 2GB, $30 for 5GB, and $60 for 10GB. The company is keeping up with its “unlimited data with no overages,” except now the data speed will be reduced to 2G once the customer hits the data allotment limit.
