NEW YORK (TheStreet) -- At its CES press conference T-Mobile (TMUS - Get Report) announced the fourth phase of its "Uncarrier" strategy that will offer credit towards the early termination fees (ETFs) from other carriers.
Shares of the carrier rose 0.5% to $33.37 Wednesday.
Starting Thursday, Jan. 9, T-Mobile will offer up to $350 per phone to customers who trade in a phone from another carrier and sign up with T-Mobile. That should cover the ETF for Verizon (VZ), AT&T (T) and Sprint (S) customers looking to switch to the fourth-place carrier.
In order to get the credit new customers must trade in their phone, transfer a phone number over to T-Mobile, and sign up for a new T-Mobile plan. Customers then have to send proof of their ETF to T-Mobile either through the carrier's dedicated website or by mailing a bill directly to T-Mobile.
