Switching numbers between family plan to terminate contract?

[WalmartSecurity]

So here's the deal: on our Sprint family plan, we have

1 line that is eligible for an upgrade/termination (has been 2 years)
1 line that is eligible in October (my plan)

Is it possible to switch numbers and plans? If I switch numbers with the other plan would I be eligible to switch carriers without paying an early termination fee?

In your scenario you should be able to switch the numbers. If you terminate line 1 as it is now, line 2 becomes the primary number any way. Line 1 has fulfilled the contract obligation, but line 2 hasn't so that's all they can really do is hold you to the contract on line 2.

You're in a good position to try to get something extra from retentions though so don't forget that.
