Any way to link 2 phone lines to same account on TMos website?

Since now both my wife and I have ported over to TMobile in the last 2 weeks, we both got those friendly TMobile texts with your temp p/w to their website account management login.

So I signed in with mine, but my wife hasn't yet. Is there any way to show her phone line under my "account" when I log in TMobile's website under my phone number?

I'm assuming this can't be done on their website and will have to stop by a retail location or call CS, but thought I'd ask first and try to avoid calling people..haha..

Thanks!

 

Hi guys..
Sorry, to clarify, my wife ported over first to TMobile and got on the $60 prepaid plan/unlimited talk/2.5GB. She received the text soon-after from TMobile about logging into her new account by using her ported phone# and temp p/w.

Then a week later, I ported over and got on the "special" $30 prepaid 100min/5GB plan and received the same text soon-after to use my ported phone# and temp p/w.

I wanted to know how to get her "account" to show under my TMobile account login.

If it can't be done online/easy way then I'll call the 611 as suggested by Crash...
