I've bought several Steam Cards from Game Stop and Best Buy and Walgreens and the ones I purchased did not work...I'm very upset because I've lost about 600 from purchasing them for my grandkids and other kids...I'm in Las Cruces, NM and would really like a refund on them..its really terrible when I call you don't have my phone carrier on your list..I have Cricket they use AT&T and Verizon towers..thanks Chris Schultz User's recommendation: Make sure you can get ahold of customer service.
