Talking about the telephone is a kind of software that can recharge the telephone bill. I bought shoes for activities today and sent two prepaid cards. After charging, why didn't I check the phone bill balance? It should be a targeted recharge card. Someone once gave me a recharge card, which is this type. I can only dial the number they gave me to make inquiries and make calls. After two days of use, I couldn't get through. It's best not to be cheated by the merchants. I said that I would send the phone bill, but I couldn't get through at all.
