TMO doesn't want people doing what you're wanting to do.
To accomplish it, you would need to:
1. Add free line.
2. Wait a year + one day.
3. Port out paid line to another carrier.
4. Keep paid line active on another carrier for 90 days (to preserve number).
5. Port old number back in on free line.
This whole process has taken you 1.25 years.
I have 2 of my free lines in a iPad and a Samsung S4 tablet, with UNLIMITED data.
You have to call them and tell them you want to use the line (promo line) in a tablet but don't want to lose the promotion and you don't want to open a new line for this.
What they did for me, was block the phone service on the line and kept the messaging and data. That way I am able to use it in my tablet.
Every summer my daughter comes and visit from Germany. I take one of the sim card out of my tablet and put it in her phone..
I call T-Mobile and have them unblock the phone service. That way, my daughter has a phone while she is here in country.
When she leaves I call them back and get it blocked again. I have been doing this for close to 5 years. So I know for a fact it works.
Tomorrow I will be calling to try and get another free line.. (Fingers Crossed)
Hope this helps

So for 9 lines (9th line free) it should be:
$310 - $40 (autopay discount) - $54 (Hook up Insider discount) - $30 X 3 for free lines = $126.
OK, now that I have the free line added (my 8th total line), and I see the promos, it definitely looks like it might make sense just to add a 9th line, even if it's paid. My situation is very slightly different, but I think this is what it would be:
I am currently at $143 for 8 voice lines (4 paid, 4 free) plus an Apple Watch line at $10 + $5 since I have the auto-pay discount on the 8 voice lines.
If I add a new line, even if it's paid, my total price should go down because I would have 5 paid lines, 4 free lines, plus the Apple Watch line:
- As chrissmith stated, I start at $310
- $40 autopay discount
- $54 insider discount
- $30 x 4 free lines ($120)
- Total $96 for the voice lines
- Add $15 for Apple Watch line, so I am back to $111
I can reduce it further by dropping the Apple Watch line to 500 MB instead of unlimited, but that's for a different discussion.
Is my math right? If so, I'm back to Costco to see if I can get another $150 on a BYOD...

"Gotcha and thanks for the clarification. I know you don't want to lose the add a line promotion and I want you to keep it as well. Using the rebate that was offered from Costco will not affect your free add a line promotion. Just more money for your pocket! I also reviewed your account to make sure you're all set for your free add a line promotion. I hope this brought some ease to you my friend. "
