Sorry if this is covered elsewhere but I didn't see anything recent when searching via Tapatalk. I just picked up a used 9.7 pro for my daughter and tried to find the 200 mb plan but it's not showing. My options under T-Mobile are: -Add to existing account; -5gb/5mos/$10; -View all T-Mobile plans (when I click on it it says Connection Failed, the connection to the server was lost); -existing plan. I'm pretty sure this is working off the embedded sim. Do I need to go get a T-Mobile sim instead? Not sure if there's a known issue of it not working with the embedded sim.
