Porting numbers with existing phones successes?

[One]

We have begun the porting process for our 2 main RP lines to Twigby.
Did all the preliminary steps at both places & even placed port-out tickets at RP for whatever good that may do.
Confirmation emails came in from Twigby within hours - no word from RP & lines are still active.
Glad it is only tuesday the 7th...as we may even be out of there on time to keep our 2 main lines away from the Ting disaster looming on the 11th that we have no desire to partake of...

Got confirmation from Cellnuvo today that they'll waive the $29 'sign-up fee':

If you are current Ring Plus subscriber, you can use the following promo code at checkout to waive activation fees:
RPFree
This promo code is good through the end of March.

Visited their site to try porting out our spare line, and after entering its infor rrom RP it says:

This is a valid device, but it appears that this device is not able to be transferred to our network.

Then tries to upsell the user to a new phone - Boo !!!

So I wonder if others here have already gotten out of RP to places other than Ting - and how long it took from initiation to completion ??

Thanks.
