Hi, I am planning to port 2 of lines from att to t-mobile. I currently have smartphones on att with $300+ ETF due. As part of the ETF reimbursement plan, can I trade-in any non-smartphone to t-mobile and receive the full ETF ? I didn't find any verbiage in the tmobile ETF FAQ regarding trading any the same type of phone. But I read in some other forums that trading in a non-smartphone is only eligible for $150 ETF. Is that true ? Has anybody who has switched to tmobile and traded in a non-smartphone confirm that they received a $300+ ETF ?
