What's the difference between the blue and white ATTWS SIM cards?
NOTHING CEPT THE WHITE SIM IS FOR PRE-PAID AND BLUE IS FOR POST PAID CONTRACT SERVICE, THE PRE PAID YOU CAN'T BILL TO ACCOUNT FOR DOWNLOADS OR OTHER THINGS LIKE TONES OR GAMES, THE CONTRACTS ONE WILL AND WILL KEEP YOUR E-WALLET INFO ON YOUR PHONE TO BILL TO AIR.
...
We use White SIMS on the regular for Post Paid and everything works exactly the same for months and months now.
