What is SIM800L module?
SIM800L is a miniature cellular module which allows for GPRS transmission, sending and receiving SMS and making and receiving voice calls. Low cost and small footprint and quad band frequency support make this module perfect solution for any project that require long range connectivity.
Does SIM800L support 4g?
Description: – SIM800 module is a GSM/GPRS module. The development board supports China Unicom mobile 2g/3g/4g card. – With NET_STA light, convenient to watch the current SIM800 state.
How do I know if SIM800L is working?
If the power to the SIM800L is enough, the on-board LED starts blinking. If it is blinking every second, this means it is searching for a network. You will know if it’s connected to the network when it blinks every three seconds. If the LED blinks very fast, this means it’s connected through GPRS.
Does SIM800L support 3g?
The SIM800L seems to be a Quad-band GSM module with GPRS. So yes it’s only 2G, but you’ve got the potential for SMS and maybe even 512kbps data. At least some mobile operators are getting rid of their 3G networks and shifting focus to 4G/LTE, but keeping 2G because of how common it is.
Does SIM800L support Bluetooth?
The SIM800 series GSM modules from SIMCOM supports Bluetooth functionality. varies from 0 to 36 depending upon the present state of the Bluetooth Module. You can download the firmware that supports Bluetooth function from here.
Which SIM is used in SIM800L?
What kind of a sim card is required for sim800 module? The SIM interface complies with the GSM Phase 1 specification and the new GSM Phase 2+ specification for FAST 64 kbps SIM card. Both 1.8V and 3.0V SIM card are supported. The SIM interface is powered from an internal regulator in the module.
Can 4G SIM work in GSM module?
Its a Quad-band 850/900/1800/1900MHz – 2G GSM module. Doesnt support 3G, 4G, VoLTE. But you can use 4G SIM which supports 2G (example: IDEA, AIRTEL etc…) But you cant never use JIO since it doesnt support 2G….

How does the GSM module work?
A GSM modem or GSM module is a hardware device that uses GSM mobile telephone technology to provide a data link to a remote network. From the view of the mobile phone network, they are essentially identical to an ordinary mobile phone, including the need for a SIM to identify themselves to the network.
Why is SIM800L not working?
You need to make sure that you share the ground between the power supplier and you use some 2 pins on your arduino to connect the GSM module. Dont try to get a fast baudrate as software serial doesnt work, try with 9600 to start then see if it response to the AT command.
Which SIM is used in sim800l?
What does the led on the sim800l mean?
If the power to the SIM800L is enough, the on-board LED starts blinking. If there’s not enough power, the LED blinks for about three seconds, then turns off. The frequency of the blinking means something: Every second: searching for a network. Every three seconds: connected to a network. Twice per second: connected through GPRS.
Is there a sim800l breakout board for Arduino?
The SIM800L is a cheap and portable GSM breakout board with all the capabilities of the larger SIM900 shields. In this Arduino SIM800L tutorial, I will help you with using this nifty device.
Is the sim800l compatible with the sim900?
Between the SIM800L, SIM800L EVB v2.0 and this version of the SIM900, I found the SIM900 the easiest to get up and running and working reliably. I haven’t figured out for sure the SIM800L and SIM800L EVB v2.0 yet but I’m sure once I do they will work just as good.
Why does Arduino module work with sim800l module?
However, these might explain why their modules work: their Arduino’s have internal regulators that drop the voltage to ~4.4-4.5 V when the SIM800L is connected they are very close to mobile network transmitters, which means the SIM800L doesn’t need to draw too much power to establish a connection
