ETF Clarification As Per FCC

According to T-Mobile Reply to FCC  on ETF - They have mentioned following as true.  I am not able to refer any documents or Term details in T-Mobile site which explains ETF for Value  Plan , how that works and what is the trial period for the customer. Do we have any document which explains that ?  Where can we obtain this document.

Here is the reference from T-Mobile explanation on ETF to FCC

9. How long is the trial period during which consumers can cancel their service without an ETF penalty? If they cancel, can they return the handset? If they return it, will they receive a full refund, no refund, or a refund minus a restocking and/or refurbishing fee?

Response:  For service plans subject to an ETF, T-Mobile offers customers a 14-day trial period, during which time customers can cancel service for any reason without paying the ETF. For customers in California, the trial period is 30 days; and for nonCalifornia customers who activate service online or over the phone, the trial period is 20 days.  Customers returning phones in these circumstances are entitled to a refund on a

handset purchased along with their activation (with the exception of a very small number of “limited edition” devices), subject to a restocking fee so long as the phone is returnedin a “like new” condition and with the original packaging.
