Another thing, if you lose your minutes with a little social engineering you could call T-Mobile and have them instill the balance once again for a certain a mount of time, they have the option as to how long it will show until it expires again. Obviously prompting you to make a $10 refill at the least. Unless you get them to add it for another year off the bat ;) some accounts have .7 cents a minute, .6 or .9 cents a minute.. don’t know how that occurs but you might want to look into it if at all.

Only problem was that I forgot to renew and lost all of it. How do you consider power or memory into the equation ? :) OK I had not done this analysis but given than $100 gets you 1 yr validity and you need to just get minimum $10 minutes to keep them alive for another year made quite sense.
