Anyone else get this email ?

I do still ( not sure why ) have a 4G booster that is still plugged in that was free I assumed. 

I did try thier Home INternet service when it came out a year or so ago but ditched it as it wasnt fast enough. 

So I have NO idea what this is about and the last 4 do not match any of my numbers… 

Also checked and had no credit on my account..

So…  T-mobile.. what is this about ?
