I had an issue with my Lavender 128, but my situation was a bit more complicated. I used my husband's upgrade like I do every even year, and I use my upgrade on odd years. I got the Note 9, of course, and he got my Note 8. So there were 2 swaps.
The Note 9 had its sim card already installed with my husband's number, so I knew the automated system activation would not work, I'd been through this multiple times. So I called and got an off shore CS with a very thick accent, I explained clearly what I needed to happen. Swap my Note 8 to the Note 9 and my husband's Note 4 for the Note 8, which is attached to my phone number. The Note 4 will become an emergency back up if ever needed, it was not reactivated after the swap.
The first CS said she couldn't figure out the problem, could she call me back in 10 or 15 minutes. I waited and no call, so I called back. Got another off shore CS, explained everything again, she couldn't do it either, she wanted me to go to a Sprint store and I told her I was babysitting my 10 month old granddaughter, and had to transport my 11 year old granddaughter to school and my grandson to half day kindergarten. The Sprint store is an hour away, I can't physically be in 2 places at once with a 10 month old.

So she finally connected me to Tech support and they were stateside. I got a very knowledgeable calm and funny tech. She went through the usual steps and still couldn't get the Note 9 to activate. She had me try a few things including the ##.... ##, it didn't work. The Note 9 was not showing up on the account. So after trying a few more codes, finally she updated the profile, I rebooted the N9 and had an LTE signal. Then she tried the same thing with my husband's Note 4 to the Note 8. More issues. Finally, after numerous reboots it was activated. What an ordeal.
I give the Tech much credit, she was truly confused as to why the phone was shipped to me, but would not show up on the account. She had never had that happen. Apparently, a lot of people had issues with activation on Sprint, more so than usual it seems.
Moral of the story... A good tech is hard to find, but worth her weight in gold when you're staring at a $1000 paperweight.
