Enough traffic with 5G, thanks. Does this include phone cards? How long can Moroccan domestic phone cards be used for ?

Dear Secretary, Mr. Wu instructed me to lead a team (four people) to Guangzhou to participate in the Group's corporate culture speech contest. The activity will end on the 31st. I would like to report this to you. The call time included is not long, but it is enough to use there. There is basically nothing that needs to be communicated by phone, and it is also difficult to communicate by phone. At most, you can ask the store to pick you up at the parking lot and take you to your accommodation.
