RCA 7" 8gb tablet can not open new Google account topic

My sister received a RCA 7" 8gb tablet for Christmas. Yesterday I was trying to set it up for her when I got to accounts section and tried to open a new Google account for her but, every user name (25+) I tried use was not available. I tried using different variation of the same username and different usernames plus there variations and none work. Anyone have this problem before and fixed? If so how did you do it?

Buying from tmobile contract free without account? topic

How much luck have you guys had buying a full price Note 4 from TMobile without a contract or Tmobile plan? I'm on AT&T and wanted to bring one over. I'm a bit leery of swappa, eBay and Craigslist as I see a lot of these scams going around where either it's reported stolen/lost for the insurance money, or they stop paying the payment plan on Next/Jump and the phone gets blacklisted.
