Can I make a phone call and send a text message without a SIM card?

Of course. Is there an emergency phone with a card in the mobile phone, such as110.12.119.120 and so on.

The SIM card is just an authentication link. Whether there is a SIM card or not, it will not affect the normal work of the mobile phone RF module.

If you want to make a phone call through the network, you must meet the specific conditions of the network operator. The function of SIM card is only to tell you who the base station is, and it does not assume the role of communication module.

In order to facilitate people to deal with some emergencies, China has some special telephones, such as 1 10- Fei Jing telephone, 1 19- fire alarm telephone, 120- emergency telephone, 999- Red Cross emergency telephone,/kloc-0. These calls are free of charge.
