4G sms Cat and sim card connector

The 4G SMS Cat with sim card connector, also known as 4G LTE Modem, is a modem that uses mobile communication systems based on

LTE-TDD/LTE-FDD/HSPA+/TD-SCDMA/EVDO and GSM/GPRS/EDGE and other frequency bands.

4G LTE MODEM can only be used together with sim card connector. After inserting the operator's SIM card, you can access the operator's

wireless network to realize data communication, voice call, SMS and fax sending and receiving, 4G Internet access and other functions. 

It can support various TCP/IP terminal devices such as PC, laptop, PDA, etc. When the SMS cat is connected to the power supply, the 4G

LTE MODEM starts to work. The SIM card of the mobile communication operator is inserted at the sim card connector, and the SMS cat

is completely connected to the mobile communication network just like the mobile phone. The computer can connect the SMS cat through

the serial port/USB interface, and control the use of relevant functions through AT commands, such as sending and receiving SMS, dialing a

phone, sending and receiving faxes, and 4G Internet access.

4G LTE MODEM generally uses drawer type sim card connector. Because the drawer type structure is more stable, it can prevent the card from

falling due to shaking.
