This is the HOME 5G HR01 unit. There is no remaining balance. The complete set is included. I only set it up for about a month after purchasing it, and since I put it back in the box, I think it's in excellent condition. There is no SIM card. Recommended for those who want to easily set up a WiFi environment. You can use WiFi just by getting a WiFi contract and plugging it into an outlet. No pets, no smokers. Please comment if interested.
