Recently switched my droid RAZR max xt926 from Verizon to straight talk. Originally got the kit from Walmart. When trying to port over my number ran into issues. Called straight talk customer services an they and to ship me a special sim. That said, it did cost me extra because I has to get a new network access card from straight talk. So $10 extra buck but I save about $100 a month I call it a win. Oh one other thing, I went in and reset the APN to default. Works beautifully now.
