Sim card reader, can the computer send and receive short messages?

Yes, but download the software to connect the card reader.

There is a mobile network card, which is inserted as a mobile phone SIM card. Basically, this function is included in the software that comes with the device.

There is a notebook with a card slot for inserting cards.

1, the card slot is only a peripheral, so you need to confirm with the notebook manufacturer whether this notebook has a built-in "3G Internet module".

2. If yes, please check whether this device exists in the network card project of the device manager.

3. If not, sorry, it can't be used.

Supplement: If you have it, you can use notebook random software, and you need to use a separate third-party software to make a phone call.
