It works like a charm! I spent hours trying to solve it!! I never would have figure that out. I was about to dismiss it. Thanks a lot!!!!!!!

I can't believe it, the problem's solved by a simple effort. But, it works. Thank's, bro. I'm from Jakarta, Indonesia.

Excellent solution, it worked . I had used Dupont wires and was struggling for nearly 4 hours , tried to extend the antenna of SIM800L and did lot of research but it could not connect to the network , Just could not believe it was such a simple solution you discovered !! , I used some good and short wires ( which I retrieved from my dead computer SMPS .. it has very good wires ..) and voila ...it worked... hats off to you dude ..keep it up

It's the first time in my life I write a comment, but man... you deserved that. The solution is pretty obvious and in the end I would probably get it, however I saved at least two hours because of you and I'm very thankful for that ;)

Your video has to be on top because it's the only solution i found after wasting hours on the Internet

Dude you are a life saver it worked like magic i've been working on that module for about 12 hours and i wached all the youtube videos and read all the articles about sim800L and the documentations there is no body mentioned about the connections before, except you. Bro thank you soo much for this ❤❤❤❤

Thanks for sharing. I discovered the same with SIM800C and SIM800L. The Dupont cables can not supply enough current when the module is transmitting. I also put a 1000 micro Farad +100 nF across the + and - terminals close to the chip for better stability. There is also a problem with the proto breadboard to supply current. I have designed Digital Circuits since 1974 so I'm a little paranoid when it comes to decoupling. They don't teach this in schools and universities anymore.

Thank you from Brazil my friend, I have spend my entire monday trying tô solve this, thank you !!!

I comfirm that worked! the current on the wire between the regulator module and the SIMCOM module is the cause.

OH Man you saved my sanity! Thank you do much i was about to leave my project And come back after mabye a week , but your solution helped me immadiately. Huge thanks!!!

I spend many hours to solve this problem,but man,your solution works great,thanks for your help.

Eureka moment for SIM800L folks! Thanks a lot man!

You are genius bro it worked and behaved as you shown I have seen many videos and visited may websites but no one told this problem I usually dont like videos even I watch it many times but this saved my whole day effort thanks a lot!

1 day wasted to make it work, fixed it in 1 minute. Thanks bro!

quick question in the code do u put the number of the sim thats in the sim800L or the one in the phone you're calling ? and also i have a sim800L Z143N is it the same wiring plz

Huge respect for you for solving one of my major problems

Thanku sir. I lost a full day with this problem, now it is fixed. Thanks from my bottom of the heart.

Wow, hermano tenía 5 días buscando solucionar ese problema, hice lo que aconsejas y me resultó de una, mil gracias. A estaba que tiraba eso a la basura. Me caistes del cielo, estoy que te mando hacer un altar😂😂😂😂, saludos desde colombia

I was getting crazy with this module. I tried everything I found on internet... why didn't I find you the first?? Thanks a lot!!

Thanks dear. My project was not working. The problem was quality of wire. Thanks again from Bangladesh 🥰

Can't believe this actually worked thank you very very much

What is the resistance value u used?

I have one sim800l blinking but inserted sim remains out of network. Can you help me to decide whether board damage or any other problem. It was working ok since Oct 2021.

Thanks from Brazil!!! it's very helpful

this just worked for me too. Thank you!

Hi Brother, this is the favour done to me by you. Thanks a lot. I was struggling to get my sim registered to the network. But was not happening. But you break it. Super super

Bro you are genius yll you solve my big problem... thank you,🥺🥺

At first i thought this was total bs! But i was so desperate still tried and it works! Man u are a genius! Never thought cables would not be able to handle 2A of current..

Hello, I wanted to ask If we use the sim800i module, can we use Bluetooth headset?

What a simple solution, thank you so much

OMG!!! It worked... Thank You so much... I just subscribed to your channel. THANKS AGAIN

ohhh brother you solved my problem.... it worked...!!! love you brother... thank you so much.... you saved me....

Brilliant, It worked !!! Thank you soo much bro..

Lot of thanks for bringing me out of misery! I was trying to power the module from an arduino 5v pin. After watching the video I realized that it can't drive 2A. I will start getting a more capable power source now

it works very well , thank you so much

Thank you for helping me resolve a big problem! thank you x1000

it really worked, thanks man

My problem is it powers up and after 5 seconds it registered to network and led blink every 3 sec But it doesn't respond to AT commands at all , did you face this problem before ?

It works, thank you mister!

thank you very much it's work with me on sim800C, it's was a big problem. the problem is solved.

I had the same problem when trying to connect my MCU to my car's OBD2 port. I was using dupont wires to do so and was receiving no response. I worked on it for nearly two months until I decided to use bigger wires and it worked! Since then I use bigger cables for every connection and never use dupont wires anymore

Seriously man ...I tried so many things but didn't work.At last it work's.Thanks a lot man

Same problem i faced during my project, actually the problem is not due to that birk connector wire gauge/thickness, the problem is due to the loose connections. We can overcome this problem by soldering the joints with the same (birk connector) wire with the reccomended battery/power suply easily. Better to use a 1000 micro Farad 16V, Capacitor connected across Vcc and Ground of sim800L for the requirement of burst current supply for short period of time.

Yeah! Awesome Bro but you didn't describe the sim card you are using 4g-3g- or 2g? Cos some guys guided that this SIM 800L does support only 4g? Is it?

I am using Sim800l GSM module with Arduino UNO and giving power to Arduino using 9V Zinc-Carbon battery. Will it work? Please reply. Its LED is continuously blinking, but not at a gap of 3second, means connection is not established. Please reply. It's really important.

Sir,can you please tell me where you purchased the sim card

THANK YOU SO MUCH

When you tried to connect directly to 1 cell lipo, both wires should be of thicker gauge. Nevertheless, thanks for highlighting this problem and confirming the solution : )

my problem is ok now, really it take 2 amperes at the begining , good explanation , thank you very much

Thanks, replacing thin wires solves connection problem.

Can i use li-ion battery instead of lipo

Bro i throught it would be easy to.deal with this module. But after buying o faced this major big probelm and k was really anoyed to it Thanks a lot for helping me out

i tired to work with this... but i try this inshallah... thenk u so much

you are the boss . thank you

huge respect sir🙏🙏

Thanks a lot, saved my day....It worked

Thank you for this help

i think what you mean is change the fiber jumper (that mostly use in project) with just a single jumper. thank you it works

Thank you This is really work 🙂😀🎉

I have used lipo battery of 3.7v 2500mah and also I have tried with 3.7v 1000mah..I have followed the same method but I couldn't get the connection. pls do help me.

Wowww.. Amazing coz it's working. Thank you very much sir.

at first i was like.. maaann, he is doing the same thing!! just powering it up.. wft is the difference!! But ive tryed my self to move my wires with the supply voltage af close to the sim800L board pins as possible at it helped.. Such a wierd issue that dosnt make any sence, But i guess the 2 A burst load, is not a myth, and kills the powersupply.. Thanks for the video..

Wow. Its really work.

Thank you, it's works

Thank you sir

thanx it worked best wishes

for those of u who still are not getting solution -- use another lipo in parallel (my single 18650 batt. wasnt able to do the the trick) huge thanks to the delta NeutRAL YTB channel.subscribed😍

Bro can i use 3.7v lithium rechargeable battery?

What kind of resistor did you cut to use connectionds?

It worked for me too. Thank you

wahhhh it worked. Thank you boy

my savior!

Good bro, its working...

GOD will bless you. this thing was a nightmare. thank you very much for the video

Thank you for the solution! I was ready to throw it to garbage!

Will it connect without antenna

Hi I need the circuit diagram if anyone can share it, please

it worked thanks !!!!!!!!

I would have liked to see you repeat this with the lipo charging circuit as if we are using it for alarm etc it is not practical to keep taking away the battery to recharge it

Greetings Dear, I have he car mirror with 3g support and the SIM card not registered to network, Will I try fix it with same method,.Thanks

Does this gsm module works on 4g sim card

Will it work plzz tell

Sir i can use 5volt 5amp smps and zenar diode 4.4volt

what happen when sim800l light is not bliinking when it is connected by arduino and pc

We cut 4 resistors what happened to the other 2?

Can I use Lithium-Ion battery (3.7 V 3000 mAh) in place of Lithium-Polymer battery?

Super concept bro

Yes its work. Thanks Bro.

bhai it worked really thanks

Pls help me AT command not responding in sim800l V2

Thanks bro

thank you . it's work

i don't hv this lipo battery.. can i use Vin of arduino which it will be feeded with a phone transformer (5V, 1.55A) ?

THANKS A LOOOOOOOOOOOOOT BRO

Hi, my module showing short when i put power on the module...i have use laptop power supply and dc dc step down module to power up the sim800L module. Now im feeling helpless... Tnx in advance.

As the wire is a conductor why there is huge resistance

thanks a lot brother

100% working 10q bro

the problem is ur power supply , max current for such a lipo battery is about 1 amps , but module require at least 2 amps to get started

Mine isnt having any indication nor any led glowing will try this method
