- This is tutorial about how to use SIM800L GSM module with an arduino. It uses only ATCommand without library.
There are so many GSM modules that came to market right now. And SIM800L almost the cheapest. It cost under 10$ and has the same feature as other. In this tutorial, we will examine how to use this GSM module with an arduino.
Still have problem with your SIM800L module? here's the solution :

I made mistake when drawing the wiring diagram. I should connect the VCC of SIM800L to 5V, not 3.3V. But it's better and safer if your power supply no more than 4.2V. 4V is the recommended voltage.
And if you are still have problem with your SIM800L. here's the troubleshooting guide :

I'm not sure since I'm not experienced on that field. But I think it should works. Compare the signal when use the antenna and when it's not
Very good it is workingfor arduino mega i used pins 50 51 instead of 10 11
Congratulations and thank you very much for the sharing (from Belgium).
didiersee thank you. Don't forget to subscribe
i'm subscribe see you soon for your next video.
what are the specifications for the sim card for this project ?
Thank you very much. I have a headache because of this problem for 2 days
Thank you for this video
Can you please tell me what I should type after s
Thank you, it is working also i used lm2596 for regulating voltage.
Great
@@miliohm I wonder, how can i send to sensor value? String SMS = "what is exactly write in this area";? for example dht sensor? Thank you.
@@uy8884 you need to convert to string. So it should like this SMS=String(temperature)
@@miliohm Unfortunately, it did not happen, i tried different combinations like this.
@miliohm: I'm surprised your SIM800L module even worked seeing you had it running at 3.3V. My understanding is that the SIM800L requires at *least* 3.4 volts and it's recommended to run at 4V.
Thank you for the useful video!
on the diagram it showed 3.3 but when he is connecting it together he says he puts it on 5v
sir module did'nt perfome any action sim 800l light blinking, arduino code uploaded all data correct no sms recvie on my number
thank you so much
Question : when making a call we should receive "ringing ringing" on serial monitor as a result?
Hello.. Pls Tell me my Led is glowing too faster. maybe not signal form my sim. my module sim is new. can you fix it for me. thank you very much
I done like it but my sim is not registering if I need to give external power supply to gps module
I dont know why my gsm is not sending any message even though it is working properly... The light is blinking after every 3 seconds. Can you tell me what could be the problem
Thanks for sharing
Sir...
I want to make sim800l based mobille phone.. plz can you help me..?
I tried it on arduino beetle and change the pin number TX (1), RX(0), but it doesn't work
Thank you.
you are welcome
hi ,it is better than to use a regulator when work with a sim800l
Hi! Nice video. I have some questions and hope you reply.
I am trying to connect it with Flame Sensor. But I already used 5V for the Flame sensor. What am I supposed to do in order to feed the SIM800L? Do I have to buy an external power supply(like 3.7V, 4V, 4.4V) and converter?
or Connecting to Ground(GND) is enough to run it?
You can try the 5V for SIM800L and the sensor. But if that looks like doesn't enough current you should buy external power supply
Hello watht's difference SIM800L and SIM800C?
is it possible to make a call more than 1 phone number using these modules
Please I have problem when I send message, I receive this message what the problem
Does this module support 3g sim card
ATDnumber
Error
how to clear this error
Plz would u tell us how to connect nodemcu with sim800l for message and calling?
gsm is not required instead you can use IFTTT services
Kalau kirim smsnya berdasarkan keadaan sensor yg deteksi terus2an gimana kodenya ya? Sensornya ngasih output kontinyu tp smsnya cuma mau sekali aja. Kecuali nilai sensornya udh sempet keluar rentang nilai yg dipakai jd trigger sms.
Sir, if we send the message from sim800l to android phone, then that show does not happen, please reply me.
Sir i want blink led through sms tell me how can I do it
thanks

Bang kalo kita mau menelpon arduino lalu mengkatifkan pin buat menyalakan sesuatu gimana caranya bang?
The code works fine and have good signal strength and the functionality is set to "full functionality" .The problem faces here is that when pressed for call command 'c' it returns NO CARRIER error an important note is that is I was successful in sending SMS. Can you please help to rectify this error?
I found something that might interesting. Check this link : stackoverflow.com/questions/30952079/receiving-no-carrier-error-while-tring-to-make-a-call-using-gsm-modem-in-pytho
Thank s .......................... :)
Do you have to use a SIM card without a pin code or is there a way too enter the sim code in the script when arduino is starting?
you must to remove pin code
so good
how can i interface sim800l with pic 16f877a ? can you help me
hi, is there an app that we can directly type there and send just like messages app without the use of serial monitor from Arduino IDE???
You can use button or another device to send the message. It is just sample using serial monitor
if anyone nothing happened, make sure the voltage is 3,7 volt and current is 2 Ampere. And buy external antenna for SIM800l module.
For 2A supply , is arduino enough to supply that
Or external power supply is required
He hasn't used any external power supply :/
Ritik Bhutani External power supply is required.
sir how to recieve call.plz can u provide me code.
Could you send the code for making call to 5 phone numbers pleaseee
My module received message but can't send a message so help me waht I do
Sir, this module is not messaging Android phones. It is a small multimedia phone, messaging it.
I am using a giffgaff 4g but it is not working, help me pleasee!!
Good day sir,
Is it possible to send messages to a registered phone number? I mean, without using the laptop but instead just buttons after doing something with the codes?
And is it possible to attach some buttons on the module to operate it with battery?
@@talin_of_earth4506 of course that is possible, even you can input with keypad. Just use the variable. And of you need to save the the number you can use EEPROM
@@miliohm thank you very much sir.
If you don't mind sir, do you happen to know an article with a step by step procedure on how to assemble the buttons?
After OK
i get reverse question mark when the sms is received and should be displayed help? 1 sms did show up but thats all now every time ''⸮''
hello. can you solve this problem?
this module has no antenna connected and its still working???? and also sim800l does not operate under 3.7V, current from Arduino is very low to support network connection
pomerai zimbango yes, and still work for me
I want to ask .. kenapaa ya AT Command saya ngak keluar pada serial monitor .. tapi call and send msg jalan sperti biasa .. cumaa ngak tunjuk the At Command

J'ai un problème quand je reçois un Sms ,l'Sms arrive avec ce message
hey are you facing the issue like sending long sentences to gsm but reciving in accurately the words when short messages sent it recieves accurately...is the problem gsm module or is it common?
how long is the sentence? maybe it took two sms?
@@miliohm just 3-4 words only but some letters are changed ...and some are changed question marks while recieving it to the GSm ....baud rate is 115200....9600baud rate not working with it
@@electricalcoder3025 did you use software serial or hardware serial? if you use software serial, it's likely that software serial can't handle at 115200. Try with 9600. Restart the arduino and SIM800L. SIM800L should automatic detect the baudrate. And if still had problem, try open my another video about SIM800L AT command. There you can try the AT command first
@@miliohm yes dude...iam using AT commands only but while doing it with 9600 baud rate ...only question marks receiving and msg even not getting sent.....so I set it as 115200 from web page...its working but...3-4 word msg ...get..some letters...get ...errored
@@electricalcoder3025 the problem Seems because the baudrate. Maybe you can try arduino Mega with serial1 so it can handle at that speed. But for normal SIM800 it should able to use at 9600
how come u use module without even any antenna connected? i m curious!
I never use antenna and always get excellent signal quality
is sim 800 ட use 5V
My module doesn't responds to any AT command. Sim registers successfully. I am using external power supply. At what logic levels it works? 5v or 3.3v?
Check the wiring. It uses 5V voltage level
I'm getting a ATD error....please help
Recieve is on Unicode Notation How can i change it? thank you!
maybe you use wrong baudrate?
@@miliohm
Thank you very much for the reply aor!
Is it possible for the gsm to send something like integers?
Of course, whatever text you need to send. Just convert it to string first
miliohm do you have tutorial?
Brother i can't understand why my gsm not getting the signal. sim card placement, code, power everything is ok but still not getting the signal .. need help
try use more current power. don't use only ardunio
@@miliohm bu
t here you use only ardiuno????
My Sim module doesn't blinking for every 3 sec..it was blinking for every second.
What type of sim I would like to choose for that whether it is 2g or 3g sim
What type power supply did you use? Sometimes just use arduino is just not enough
I've used the cable supply only (data cable)
@@vamsisai5235 maybe the current is just not enough. Sometimes happen to me too. Try using external power supply that can supply 2A current. Set the volatge to about 4 Volt. You can use step down to set the voltage. Watch my another tutorial about http request using SIM800L. I use different power supply there.
How can I use SIM800L for sending LPG leakage alert? Please provide me detail circuit diagram and code.
I have done everything like this ....and connected the Board using Laptop's USB.
1) Module is ON,
2) LED is blinking every 3 seconds.
3) Module is in TEXT mode.
4) Incoming SMS can be read and displayed on the Serial monitor
Problem is that whenever I am trying to send a text SMS, it is delivered without text (means an empty/blank message) to the recipient. On the screen, it just shows "SMS Failed"
Can you please help me out on the root cause of this?
maybe the problem is in your code? did you edit the code?
can work on 5v in arduino mega? or just 3v
Sometimes it worked
I did as u said...but it's not working...please help me because I have a project to submit on this before this month 25th..!
Teja Pothukanoori what's the problem? I can't help you if you don't expalin the detail
miliohm my module kept blinking for every second.....please help to get signal
miliohm it worked fine yesterday night...but now, it's not getting signal

Abdesslam Merrouche what's the problem?
miliohm when I send the program from the ardwino the gsm didn't send the message why I don't know ?
I did what you do in the video
link does not work !!!!
I did as the video but I got an error when I press s
what it said?
miliohm it said ERROR
hello will this ruin my sim card if i do it to my daily one ?
No, I also test it with my daily sim card
@@miliohm omg thank you dude
thanks you for this video now i know make call what i seek since but when i send sms from my smartphone the serial monitor don't display my sms it display a string of numbers please what's the problem?
number like what?
Hi, your serial print is probably in PDU format. Try to include "AT+CMGF=1" in your code.
Bro can i send multiple message at a time
Ini think it can't. This device works just like Cell phone
In your code you wrote only one phone number to make a call and send sms then how to make a call and sending sms to more than 1 phone number
Just make another variable with new phone number. And call the function with it
I need help.. I try your code, manage to send SMS make call, but I don't receive anything on my serial monitor.. Just "system started.. Type s for sms....." what ever I type it doesn't show on serial monitor
Check the wiring, and what power supply did you use?
@@miliohm I am using sim 800L v2.0 EVB.. Your code works, I type s and it send SMS, c for call. all works. But on serial monitor It doesnt show what I type.. just "system stared..." Wiring is ok, power external with dc to dc converter and grounded together. Is there any possibility to send you my code and what I'm trying to make.. I really need help.
What is this error plss help
any one please help

Hello, my sim800l blink 7 times and wait for 3 sec. and repeat again please help me!
Usually it's the power problem. Use power supply with more current. Don't use only arduino
@@miliohm I use with my computer. ıf ı feed to arduino with other battery like this www.robotistan.com/6v-13a-kuru-aku will it ok?
@@saldoc itu should be ok, don't forget to use Vin or black power cable port in arduino. Because arduino should powered only with maximum of 5V.
@@miliohm ıf ı feed arduino with 6v 1.2A battery, could it be problem?
@@saldoc the ideal should be about 7V-12V if you use power pin. But you can try 6V battery with USB to computer still connected to gain more current.
my sim 800l led blink fast, it mean that no signal so what should i do
yem longthay how long you've wait? Normally itu should not more than 10 seconds. Make sure the position of simcard is right. There is a small picture on the cover about position of simcard.
it blinked three times and stop for awhile before blink again
i wait for along time but it still be the same. sometime it's stop blinking nearly 1 minute and start blink three time again. i followed all the same thing but it doesn't work.
my monitor display only " system started"..........
yem longthay what type arduino did you use? Did you connect another device like sensor to arduino? It can caused by LOW POWER. Try using external power like adaptor. Make sure the ground from adaptor connected with ground of arduino and SIM800L
LED is not blinking and no Led is ON ..What can i do now?

maybe the wiring is wrong, it should immediately ON after you wire the vcc and ground
@@miliohm it doesn't turn on ..
I connect the vcc pin with Arduino vcc .. no led is blinking ..
Is it supply current problem ??
@@miliohm i checked it many times brother .. bt no response.
What can i do ?? Can i connect with other 5v supply ??
@@k.m.sayembinrahmotullah8721 try lower voltage like 4.2V. Use one or two diodes from supply before connect to gsm module to drop the voltage.

bro, ane udah coba tapi lampu kedip terus kadang mati begitu terus, volt udah aman 3.7-4.2 , dan jugga pas ane mau ketik di serial monitornya malah gk keluar tulisan s/c yang ane ketik itu kenape ya ?? soalnya udah diketik ketik malah gk keluar tulisan yang kita ketik padahal udah dienter
arus kekecilan paling bro, coba kasih adaptor yang 2A. Jangan pakai arduino doang, terus pastikan posisinya ga susah sinyal.
kalau agan pake kartu apa ? paketnya ?? ini punya ane udah kedip terus katanya kalau kedip terus gk ada sinyal, ane udah pake antena soalnya tapi tetep kedip terus setiap detik
tadi ane nyoba tanpa kartu sim800l nya lancar kedip terus di 3.8v , tapi saat ane masukin kartu indosat nya gk stabil kadang 3.3 , 3.5 , 3.8 begitu terus itu kenapa ya ?? padahal ane udah pakai voltage regulator lm2596 biar 5v jadi 3.8v
tapi sumbernya apa? kalau sumbernya arduino mah sama aja. Coba pakai regulator tapi sumbernya adaptor yang minimal 2A. ane pakai simpati.
Hello I type “c” “s” but no response. what should I do now?
did you make sure that your SIM800L already registered on network?
@@miliohm yes i did
@@linhlequang2957 make sure your TX/RX connection is right. TX should connect to RX and RX to TX. Did the LED blink slowly? what power supply did you use?
@@miliohm i use power of the board arduino uno(5v), the LED blink every 3 seconds, the TX/RX connection is right
@@linhlequang2957 you can check communication first using AT command in serial monitor. See at my other video : m.ua-cam.com/video/HjFX40tYIec/v-deo.html

what it said?
miliohm the Sim was not getting detected ...
KK TALKIES maybe the position wrong?
No .. I checked it all..
sim.println("AT+CMGS=\"+91xxxxxxxxxx\"
"); i dont want to write this. i want to write mobile number on serial monitor in arduino and on that number, i want to send message. how can i do?
you can use AT command directly from serial monitor. Check my another video about SIM800L
Modul GSM nya pake yg merah itu/bukan om?
iya SIM800L seperti di video
Bro kalau pas kirim sms tiba-tiba ada notif error pemecahannya bagaimana?
Error gmn bro?
Bang tegangan dari arduinonya masih terlalu besar gimana nuruninnya yahh.? Tolong jawab bang
Pake stepdown aja, biar stabil. Bisa sih dikasih dioda dulu setelah 5v sebelum ke vcc SIM800nya. Tapi kadang kurang stabil
@@miliohm iya mas sya pake dioda sama kapasitor tapi tetep aja belum bisa
@@KuliOnline009 kalau mau stabil lagi, pakai power supply sendiri mas. Minimal 2A. Lalu pake stepdown agar turun ke sekitar 4V
