Can the t-mobile store use my old phone to see my texts and data
The t-mobile store transferred my phone data to my new phone - they showed me they deleted the data from the old phone with the clear data button. But I had a strange text come on my new phone while I was texting someone and I didn't type the text and am not sure where it came from. Could the store still have my data and the ability to use my old phone and see what I'm doing on my new phone?
