The secondary card of the mobile phone receives epidemic information

Then pay more attention to the epidemic and send messages just to remind you.

As long as the dual-SIM dual-standby mobile phone supports the mobile phone card, there will be a signal worth displaying after installation. When the signal is displayed, it means that the two cards can accept text messages and incoming calls at the same time.

Epidemic refers to the occurrence and development of epidemic diseases. Larger epidemics that have occurred on a large scale include Severe Acute Respiratory Syndrome (SARS), Influenza A (H1N1), and Coronavirus Disease 2019 (COVID-19).
