Works as a charm. Thank you
Hi...are both modules reliable for industrial applications? Have u ever tested these GSM modules by running them for some weeks or months?
how can the recieved message displayed on the serial monitor be converted to a string?
Hi i used SIM900A for this project but when i type the (CMD) C for calling its not going....what to do ?
Hello, thank you for this great tutorial. I found datasheet of the SIMCOM chip but where can I find datasheet of the EVB board ?
Followed the instructions but using pic18f assembly . Mail is sent but the phone says content not supported. Any ideas?
Great video. But im working with a rele, and if the contact is continuosly closed it continues sending messages until I open the contact. How can I solve this problem?
Could you tell me how to buy a phone number recorded in the SIM phonebook with the AT + CPBF command, or one that will give you a result, please
Is there any AT command for sending SMS to the SIM address book?
BEST TUTORIAL EVER !!! ! ! ! ! 1 Million
THANKS
Thanks!
Can help, led 1second blynk
can i know this version 2 can connect with arduino nano?
Hi Sir! Do you suggest any SIM800L V2 library?
sorry may i ask. im following ur step and when im uploading it spamming '?????????????????'
hello! can i use this code to inform when there's a detection detected?
Thank you
what library are you using
Really neat explanation✌Can I send, receive sms and calls with 4g sim card?
How about the issue with peak current usage? since it can be connected to the arduino, how will it handle currents up to 2A?
It can't handle up to 2A. but sometimes it just work under 2A.
ATD+(my number);
ERROR.
Any idea?
Hi can i ask if it supports 3g to 5g sim card?
hi sir hope ur doing great im right having a problem ,the module keep blinking and cant connect to the my sim card even if im using the xl4005 DC-DC connecting to my sim800L v2.0 module , i guess that the problem is in the network registration processus ,can you give the specific and successive AT commands that shoud i use in order so i can connect my sim card to the module ?
Hello i have same problem how can i solve it ?
Hola muy buen video, tengo una consulta, por lo que vi en varios videos, en el codigo tenemos que poner el numero de telefono al que queremos recibir el SMS. Pero por ejemplo yo necesito mandarle un mensaje al SIM800L preguntandole si esta la luz prendida y que me responda SI/NO, pero yo quiero que lo puedan usar todos los integrantes o cualquier invitado, (no se si me explico) ¿no hay forma, por ejemplo de mandarle un mensaje al SIM800L, que guarde el numero de telefono desde el que recibio la pregunta y responda a ese numero ? luego si viene otra persona con otro numero de telefono distinto, manda un mensaje al SIM800L que guarde el numero y le responda a ese mismo y asi??
(no se si logre explicarme)
Saludos!
nays nays thank u
How can you make the call just by pressing a button
Please show how to let the sim send each second a signal to my phone oder to a webside.
Or how I set a time lile 1/minute 1/sec ...
This is great tutorial. But will it still work if I plug my gsm module on different source but still the output is on the arduino?
yes it will be fne
Hello, thank you for your videos, very useful. I ask you, you propose the 800L connected to the 5v of the arduino but my question is, when you send or receive an SMS or calls, the consumption of the 800l can be up to 2A I understand and this cannot damage the arduino or both boards? Also, what is the difference between the SIM800 L and the SIM900? Greetings
It can not micro, speaker
it can not damage?
Hello,😊 I would like to ask where I can buy those hardwares online?
Good afternoon It is not clear where the SMS text is stored and how to write it to a variable.
Wow amazing, looks better than v1, I have one question, it have GPS fuction? i need to send via SMS my location .... it's posible to do it only with this module or I need to use GPS modulo like NEO-6M???
Yes, you need GPS module. This module doesn't include GPS
@@miliohm TY!
please make tutorial with gprs connection
Hi, great video! Does the module turns on automatically when you apply power? In the datasheet is states that the module has a power key pin that must be held low for at least 1 second for power on/off. Thanks!
yes, but the power supply is critical.it uses 5v with peak of 2 amps at very high frequency transients. Put a more than 470uF capacitor with power supply. LM2596 with capacitors work well.
If power supply is inadequate, it will keep resetting itself and never managing to register to network.
Thanks for details, your solution solved my problem
@jeetenz hurlollz I have the same problem with my SIM800L EVB v2.2, I'll be sure to give this a try. Thanks..
@@jeetenzhurlollz8387 can you explain to me how to connect capacitor with 5V output of arduino?
+ capacitor on VCC of SIM800L and - capacitor on SIM800L GND
LOVE U MEN
Dou you have some code for making call , receiving and send sms with raspberry
Can we send SMS to multiple number? Thank you
does SIM800L wirk with 5G sim card?
Hi, I am using the esp32. I follow your instruction. However, the last function _String _readSerial(). when I comply the code, it said In Function 'String _readSerial()': warning: control reaches end of non-void function [-Wreturn-type]
Can you help me to explain the function of String _readSerial(). Thank you so much.
I am using esp8266, the network does not register, maybe you also need to connect a capacitor to increase current. That error is due to the network not registered, thus sim is not detected
You resolved it? I have the same problem
Can you send/receive USSD code ?
Can I use LM2596 buck convert to provide 5v 3a to this module?
I'm going to make my project portable so I need to use 18650 battery instead of adapter.
Single 18650 should be boosted since the voltage around 3.7V. use boost converter like XL6009. LM2596 used to stepdown the voltage. Did you use some 18650 in series?
Or you can use the red SIM800L (v1). It can be powered with voltage around 4V.
@@miliohm Thank you for reply. I use Sim900A and two 18650 (in series) on LM2596 5v
fixed 3a which I made by myself by watching youtube tutorial. I don't know why network never established. I guess my micro-sim card is not properly seated in the module's lid. So I'm looking for new GSM module.
@@jumbo999614 try watching this video to find the cause ua-cam.com/video/qI8vdiQdXtA/v-deo.html
What a great video and thank you very much for sharing your knowledge. I have implemented your program and it does not compile for me by Serial.println(_buffer); and the error it shows me is: unterminated argument list invoking macro "F"
can you help me to solve it thanks Edwin
did you copy the sktech from my website?
hello. i am from norway and i am doing a project that uses sim800L. i have a telia sim card which wtill has 2G network and still my sim800l V2 is not finding network. i get no blinking not even without sim card inserted. the network light is just off all the time. can you help me?
try watching this video, it has step by step troubleshooting for sim800l. Even it uses the sim800l v1. It almost the same.

With out serial monitor this project is not worked. When I send 's' from mobile to 800l then 800l send sms to my mobile as reply. With out serial monitor connected.
Can I use SIM 800L as the module in a way that can send SMS of the GPS location once the button (SOS) is pressed? Do note that I have used Neo 6M module for GPS tracking... So is it possible to automatically send an SMS alert to predefined mobile number??
Sure, I think many UA-camr already made that
@@miliohm Thanks for the reply!! Can you please provide the link to any tutorial ?

good day! my sim800l v2 can send texts but not links or urls. can i ask how this happens?
Hi what sim did you use did u use a 4g sim?
Makasih bang
I tried it by connecting module with arduino UNO but its not connecting with it ..???
Any reason please guid
this tutorial does not explain how to connect speaker/microphone, can you explain how to do it?
Can you share how to connect the SIM800L V2 to Blynk using GPRS? Thanks
There is a library for that actually. It's easier, you can google it
the module is ready but cannot send sms
the code says no dialtone how can i fix it
Hi, I actually wanted to ask that I'm using sim800l with Arduino uno to send SMS and make call simultaneously one after another but the problem is that after connecting to network call function is working really fine but SMS are not sent somehow,.... I've tried tons of code but SMS are not being sent please help if anyone can ! I would be really thankful
Try watch my video with the title SIM800L Troubleshooting guide
how to fix if it says can't open device. ASAP AHHA
Can the GSM be fed from the Arduino or should it be an external power source?
It has 5V pinout. So it should works with 5V input. Unless the current is not sufficient.
@@miliohm But arduino does not output a current of 2A which is required by the GSM module. How then can it work? I have tried powering the GSM with arduino and did not get any blink from the GSM LED
@@mutheuatsiaya6451 Hi! Did you solve the problem?
You should try external power supply. Like 5V adapter
I even try external power supplies of 5V with 2A but its still not connecting
Hello
My sim800 doesn't found the network. When I put the voltage D2 is on.after D6 is flashing 1 second every second and D2 is on 7 seconds and off 2 seconds.RIO and R7 always off
Can you help me . Thanks

Same here i tried externel power lm2596 but same problem
god belas you
Great!❤❤ By the way, I wanna ask if it can send message without a Load specifically here in the Philippines. The case is I wanted to inform the receiver using sensor. If the device detects a sense, it will send a message to a mobile phone. I only want arduino to send message and thats it. I am a student and I wanted to include this onto my research device. I hope someone will notice me po. Thank You 🤗🤗
Hindi sya makakapag send ng message if walang load yung sim.
@ Pwede po ba gumamit ng 4G network?
@@nellynfedejuan1212 yes po. Pwede.
Ahh, sabi po kasi pg Sim800L hindi dw po gumagana. Phase out na dw kasi yung 2G na Simcard dito.

Works for me
@@miliohm hi I am stuck on a project and don't know what's wrong with it can you help me?
@miliohm are u using 4g simcard? or what
Yes, but the module only has GPRS ability
Sms800L doesn't work, is only for 2G, and in my country is not longer available
Didn't work for me in 2023
sir, can i used 4g sim for sim800L?
In my country. I can use 4G card. But sure, the module, only works for GPRS/EDGE
No i2c device found pls help
It's not even use i2c
hello, why mine is error?
same, did you find some solutions?
I don't know whose code it is actually, because I can see the same code being copied and pasted in various channels.
