I charged my girlfriend 500 yuan for the phone bill. Will it be displayed on her mobile phone? I know it has been charged.

You will receive a text message from the communication company.

Charge the other party's phone bill, and the other party knows. If a person's mobile phone is recharged by others, he will receive a short message notice from the communication company. In other words, the owner knows that someone has charged his phone bill, and he also knows the amount of the recharge, but he won't know who is the person who charged his phone bill. So you can send a text message to the other party, or reply to the other party through WeChat, and you have already recharged the phone bill for the other party. The other party will know who you are from your SMS or WeChat reply.
