Husband and I have 2 phones with T-Mobile. One rep said it didn't matter what phones we had the sim would fit, WRONG! Called back next rep said now we need new phones AND chargers WITH the block! That's INSANE. Some random phone that I can't even use a generic block in?! Lonny story short saved us only $15 a month and thank god the sim didn't fit. Went to T-Mobile they took us right back and fixed it all and actually lowered my bill!
