Pros: cheap
Cons: problems with adding minutes, TERRIBLE customer service, supervisors lied
Summary: The air time I bought NEVER added correctly to my phone. The wait on the phone was ALWAYS longer than 20 minutes. It ALWAYS took more than one hour to solve one simple problem. You think that's the end? NO. They would promise you one thing, and that would NEVER happen. You would have to call again, go through another hour to solve the problem.
Case 1: I bought a new phone. They sent the wrong phone. After a long wait, I got the right phone but it was broken. Again, after many days of waiting, I got a functional phone with a wrong SIM card. I called and argued.Finally, I got the right SIM card. The whole process took me more than a month.
Case 2. They sent me the wrong SIM card for my parents' phone. Because I was going out of town, supervisor X from the company told she would make sure I received the SIM card in 1-2 days. After 4 days, I was still waiting for my SIM. Supervisor Y from Net10 told me I would received extra minutes for the long wait. On the 5th day, I called again, and supervisor Z told me there was no documentation for my previous 2 conversations. So.... either they all lied to me or I was talking to the air.
Bad experience. NOT RECOMMENDED.
