Pay top-up through third parties such as Taobao or operators.
Merchants who provide online recharge services through Taobao pat. , buy products as a recharge service to recharge and pay by credit card. Generally, there will be a discount for Taobao recharge. For example, the phone bill of 50 yuan Mobile is only 49.8 yuan. But recharging in this way is risky. First, the recharge time is long and short, and second, there may be fraudsters.
Recharge directly in operator official website through online payment. For example, in many provinces, mobile can pay directly online, and sometimes there are preferential activities. For example, 100 yuan to send phone bills to 50 yuan is more cost-effective and convenient than buying prepaid cards in cash at convenience stores.
The above is my personal suggestion, I hope it will help you.
