answer:Net10 has good customer service. They aren’t always fast-fast-fast, but they do eventually get the job done. He can go online and discuss the problem with them via their website or call them (from another phone, obviously) at 1–877-TEN-CENT (1–877-836–2368). (You can’t make the call for him, as they will be asking questions about the phone serial number that you won’t have, and probably have him enter codes into the phone directly to reset his minutes.) Good luck.
