You can buy a Red Pocket Mobile SIM in a retail store like Target or Best Buy or order it online from their web site. I could still use the nano SIM in my Nexus 5 and Lumia 920 with a nano to micro SIM adapter. I wanted to buy a nano SIM because that is the correct size for my iPhone 5s. Since I was signing up for their GSMA service, I needed to buy a SIM for my phone. That leaves just their CDMA, or Verizon network supporting 3G. According to their web site, their GSMA, GSMT, and CDMAS networks all support 4G LTE. These four networks are their AT&T, Verizon, T-Mobile and Sprint networks respectively. When you sign up for Red Pocket Mobile, you need to choose one of their four networks: GSMA, CDMA, GSMT, or CDMAS networks. My goal was to try Red Pocket Mobile with my iPhone 5s, Google Nexus 5, and Nokia Lumia 920 with their AT&T compatible network.Unfortunately my Lumia 920 stopped working, it doesn’t recognize SIMs anymore so I was unable to use it for this review. It also means you can buy a discount monthly prepaid wireless plan and still get roughly the equivalent service you had on one of the big four. In general this is a good thing, because it means that in most circumstances you can bring your own Verizon, AT&T, T-Mobile, or Sprint phone to Red Pocket and it will be compatible with their service. Red Pocket handles all the sales, marketing, support, and billing but if you use Red Pocket Mobile your phone will be using one of those four networks. This means they don’t own their own cellular data network of towers, instead they lease service in bulk from the big four wireless networks, Verizon, AT&T, T-Mobile and Sprint.

In the industry, the are what is known as a Mobile Virtual Network Operator, or MVNO for short.

Red Pocket Mobile is a prepaid wireless company.
