I went to the T-Mobile store and was thinking of switching to their service, because I recently moved and AT&T coverage is really bad at the new place. The rep said that in order to get post-paid service I must provide my SSN and have them run a soft credit check. Pre-paid service doesn't include features like wifi calling, international data, and free calls to Mexico and Canada. I asked if it's possible to pay a deposit. He said they only know whether to take a deposit or not after they run the credit check. So, has anyone here signed up for T-Mobile post-paid service without an SSN? This blogger: http://www.forbes.com/sites/adamtan...bile-really-need-your-social-security-number/ says it's possible, but that was written in 2013. Has the policy changed, or is the store rep incorrect? Thanks.
