I work odd hours so I am unable to easily call T-Mobile support. My wife moved to a different provider for work, so I need to drop her line from my account. (Her EIP is paid in full) I want to switch to an individual simple choice plan instead of a family plan. If I am able to do this online instead of over the phone it would be greatly appreciated. Thanks.

Beyond that, I BELIEVE their phone lines support something like 9a-10p in each time zone, so that means 9a eastern to 10p Pacific (which is 1a eastern). That SHOULD give you enough of a time frame to call in to Customer Care. Plus, they're available 7 days a week, which you shouldn't be working 7 days a week. It's even illegal in some states
