Replying to: Q&A For Cell One to AT&T Transition - Part 2 (LONG) by hardcorehavok
A: Anyone who signed/signs a contract between now and the time the transition occurs, will have the existing ETF policy which is $20 per month left on their contract (per line as well if canceling more than one contracted phone). AT&T's ETF policy is a flat $175 fee. It doesn't matter if it is 31 days or 23 months into the contract. However, Cell One's current trail period for new service is 14 days whereas AT&T's is 30 days. That will definitely change to reflect AT&T.
UPDATE: AT&T Mobility recently announce that they will go back to prorated ETFs. It will be $20 per month (per line as well if canceling more than one contracted phone). This is the same as Cell One currently does.
