Red Pocket Colors

Okay, I'm pretty smart and all that, and I'm able to look to the Red Pocket plans on eBay and Amazon and figure out that yellow is Sprint and red is Verizon. (Yay, me!)

Blue would seem to be AT&T except that there are light blue and dark blue SIM kits. Does anyone know what the difference is?

And, on Amazon, there are peach colored SIM kits. Any idea what network those use?

Thanks, in advance!

It is important to note that the Ebay Red Pocket "Ultimate plan" which offers 5Gs of data with unlimited talk/text for $240 per year is AT&T NETWORK ONLY

sprint as well for the annual plan

ATT only for the monthly version.
