Recently switched over from Virgin Mobile to the T-Mobile $30 Walmart prepaid plan, and am about 3/4 of the way through my first 30 days, which ends on the 12th. So my question is, can I put $30 into my account at any time (like now) before my 30 days are up, and TM will then automatically deduct it from my account on the 12th to pay for the next 30 days? That is how VM worked, and I always paid a few days in advance. In regards to TM, I had read a post somewhere about TM prepaid plans that implied that as soon as you deposited your monthly fee into your account, your new 30 days started right then, but that doesn't seem right to me. Can someone clear this up please. Thanks. BTW, very happy with this plan so far. Speeds are waaaaay faster.
