I bought this 3 May 2014, I served 2 times! It has failed and that Amazon considers that neither the past nor time are the company that sells Radio Sim, want not replace me! Lamentable when I bought a lot on the site. So I do not recommend this product, and advise you to be wary of purchases made on the Amazon site! Apparently, for them, we're good and then has to pay for the sav there more person
