Whitelistandregularusage plan? Really?

So just to add to this. Last night I was on the phone with tech support. The first person of tech support couldn't do anything with my whitelist plan issue. She then switched me to the real tech support who had to put me on hold to discuss this with what I believe was going to be super tech support. I was then hung up on and have yet gotta call back. After that I did a goggle search and found this thread. Go figure that T-Mobile tech support can't answer our question but here sits the answer for the issue. So here it is in a nut shell. 
1- the primary account holder had to login to your T-Mobile app on your phone

2- go to the bottom and tap account. 
3- somewhere on that scream towards the top find a red line that says ad ons 

4- that will show the primary phone and it's add ons. If  DATA only has a blue dot then scroll down to your plan and tap the empty dot turning it BLUE. Scroll all the way down and tap accept and change. 
5- make sure the plan you tap has the word free next to it as that will be your plan. 
6- you can then check other phones lines on your plan by tapping on the add ons feature and select the phone. I also had to do my sons phone last night. It may take a while for you to notice your plan has changed. To check the function see if you can access the internet and text using lte or 5g

This worked out the problem  and I hope it's helpful to you. I only wish T-Mobile tech support would copy and paste this to there trouble shooting line for when this error or change is made
