thank you so very much, a bit of searching and this is the first video I found after a good bit of searching that covered SIM usage properly and was not just about setting up GSM with a over built module that used more power than I needed. they also did not cover the basics and basic tool information like you did in such great detail. My usecase is a little different but now I finally have a good understanding of the direction I am going in.
Great explanation, thanx
very well. step by step tut!
Great video! I've just bought one of these modules. Could I simply drop a 5 volt supply through a diode and provide a large capacitor after the diode, to power the module?
Thanks for your sharing, I got stuck in the ctrl-z command. I need to press the ctrl and z keys simultaneously from the keyboard. how should i do.
thanks for your sharing i was stuck on ctrl-z scroll keyboard. how should i do
Very helpful
Amazing!
Hi ... Great video !
Can the bell output be fed directly into arduino digital port to detect hi/low .. I want to trigger a relay and operate a factory analog bell ..
Thank you
Paul
Great Explanation Dear. Hats Off
Thanks for watching!
Hi. Thanks for the class. One doubt: the SIM800L is only 2G? won't the 2G system end? therefore, can using this module be a problem?
Very good.

Good day sir,
Is it possible to operate the module without the laptop instead with the use of buttons? Like you will do some coding then attach some buttons to the module that if you'll press, it will automatically send the message?
Yes, I made a video interfacing a gsm module with a microcontroler and used a motion sensor to make a stand alone alarm. You can modify the code to use a button and send a specific message : ua-cam.com/video/Ph6yolRmD4E/v-deo.html
Did you check how many SMS could you send in a minute? What is the SMS throughput? I would like to make my own SMS gateway for 2 factor authentication and notifications, and this looks like a neat solution!
For my application, I don't have the need to do that. Sounds interesting.
one hour one ports can send 800 sms

there is a limit in gsm/2g itself. you can simply look it up, its not specific to this module :)
Sir, this module is not messaging Android phones. It is a small multimedia phone, messaging it.
my Question is whose number write in the code (String number = "+xxxxxxxxxxxxx";) that are insert SIM in module SIM 800L or other On which we receive message or call
Hello!
I want to use jio 4g simcard..
can i use such sim with sim800L gsm module??
help me please....
thanks in advance..
Same here. Plz amswer.
No.. the GSM modem is GPRS which is 2G .. so you cannot use jio..
u can use a 3g sim
It will work, but the data connection will be limited to 2G
Sir I want to know how to write code for a pic/microcontroller interfacing with GSM can you refer me to any platform
That is what I have done. Everyone seems to use Adruino.
Can we directly connect sim800l to 5v? Will it fry chip?
The input voltage of the sim880l is about 3.8V - 4.2V.
Im using a giffgaff 4g it dont work, Can you help me figure out what im
doing wrong, what sim card do i need and how do i get one.
Not familiar with giffgaff. If the sim card works with unlocked gsm devices then it should work with the module. If the your sim card only works with a particular carrier then it will probably not work.
First try using your card in a unlocked gsm phone. If it works, then it might work in the sim800.
Eye-On-Stuff I ordered a 1pmobile sim card... works perfectly 👍
Bro in my project sim800 l blink after 20-22 seconds plz help me network doesnt stable
Or
2g sim is mendatory or 4g can be used plz help bro plzzzz
If you have not tried it. I would use a regular Tmobile sim card and set it up for pay as you go. Just put maybe $10 on it. Verify the sim card is working on a unlocked gsm phone. You can find them on ebay amazon or even the tmobile store. Make sure your serial connection is good connected to a terminal. AT > Ok. The OK does not mean your sim card service is ok.
-Tmobile sim card pay as you go
- check wiring
- verify serial communication
- Are you in an area where you have tmobile service? Verify with unlocked phone
- Is your sim800l bad?
Hope this helps.

Can we connect sim800l to esp8266.?
Please send me the code.
Sorry, my compiler only targets pic microcontrollers. Thanks for watching.
hello sir ur explanation is good but how to write code for it.
buzz me for coding with arduino
SIM800L Problems: Setup:
1-Checked ATT coverage for 2G at my location. Covered OK
2-Used SIM card from my phone to make sure it was active and working.
3-Used a 12Volt, 10 Amp/Hr. battery as a power source.
4-Used a 3 Amp 'Step-Down' converter, set to 4.1 Volts output.
5-Used 25mm (about 1") long power leads, 20 gauge, soldered directly to the SIM800L board.
6-Tested with 2 antennas (the helix included) and an external IPEX Connector Antenna.
7-Using Putty, communicated with the SIM800L module with AT commands.
8-Communication was OK, working but NO connection to the ATT network.
(Did try my bench power supply as well, same results, LED blinking at 1/second-no connection)
In all cases, when powered up, the SIM800L LED blinked once/second. I then transported the powered up
SIM800L to within about 150 meters (about 400 feet) of the nearest ATT Cell Tower. I disconnected power to
the module and reconnected, LED still blinking 1/second. I powered down the module, removed the SIM Card,
cleaned the contacts and re-inserted the SIM card. STILL within 150M of the ATT Cell tower, I powered the SIM800L up, still blinking at 1/second, waited about 10 minutes, still blinking at 1/second, no connection.
NOTE: Replaced my SIM card in my phone, all OK.
Any suggestions would be appreciated.
AT&T sunset their 2G network years ago. 3G is the oldest standard still in use by them. You would need a T-Mobile (or one of their MVNOs) SIM card, as they are the last 2G provider in the US.
@@daynater MY BAD!--I looked again,...OLD MAP! AT&T 2G DEAD, Verizon 2G, DEAD at the end of this month. T-Mobile 2G DEAD in 2020, etc. Any Idea what module to use to duplicate the SIM800L with 3G?
Adafruit has a couple 3G and LTE options for modules. they may be backwards compatible.
I would try a Tmobile pay as you go or prepaid sim card. You can find them on ebay, Amazon or even a tmobile store. Call 1-800-866-2453 to activate as pay as you go. You can just put $10 on it for testing. You can even buy a sim card by calling the tmobile number.
can i use the same circuit with arduino as well !
buzz me if u need assistance with interfacing with arduino and coding
Yes,
Where is hech is cnmi?
can i use this for 4g sim ... ? plz anseer

yes, you can if the gsm modem it is 4G device
@@natalielin7261 thanks .. 👍🏼
Can I use Arduino uno? Please send codes for it I need it ASAP
My compiler is pic basic pro from Melabs. I don't use arduino. To answer your question, Yes it will work with arduino. I'm sure you can find code out there for arduino.
