SIM800l Powering 5v DC | SIM800L Not Connecting To Network

Ahmad, you are my friend :) This video solved an annoying problem. Thank you a lot!

[@AhmadLogs]

MOST WELCOME

[@renzocarignano373]

Hello, thank you very much, I was trying to get it to connect to the network without success, but thanks to your video I was able to do it, thank you very much.

[@AhmadLogs]

Glad to hear that

[@marianagradoscelsius1590]

I connected a capacitor of 10uF and powered it through my usb port, it worked! Thank you

[@AhmadLogs]

that's great

[@stephencarlm.calatrava8877]

By God's grace mine worked, the set-up I had though was using two 18650 batteries in series-so total voltage was around 7.4V, and used a buck converter stepping down the voltage to around 4V and connecting the output of the buck converter, directly towards the SIM800L Mini GSM module, I made sure that the wires I used was as short as I can enable and used AWG24 wires, I did not use any capacitors, and everything worked fined, I even used 5G capable SIM card and it worked well with no problems; hopefully those working on this had theirs working, God Bless

[@AhmadLogs]

you are right must use best quality wires also power supply must as close to the sim800l as possible. you can directly attach single 18650 without buck convertor. just try it. I have use single 18650 battery in my most of projects without using buck converter

[@stephencarlm.calatrava8877]

@@AhmadLogs yes indeed 😄, one 18650 is already enough, I used two 18650 in series set-up because of the project I worked on

bro if you mind me asking. what sim did you use? are you from the philippines?

[@stephencarlm.calatrava8877]

@@vincepapolonias1599 yes po, from the Philippines, I used a 5G TM SIM card, the GSM module uses the micro SIM size, though the GSM module itself operates at 2G using a 5G SIM card did not cause any problems, it worked fine

[@rollerkingonce]

I keep burning the module . I bought a second one and it does not turn on again... I am doing only 3.7 battery.

[@rochdimaria]

This is the only solution working for me. Many thanks

[@AhmadLogs]

so nice of you

[@oliviermeunier1594]

This is confusing, but works, I'm able to connect for the first time Thanks... I can move forward now

[@AhmadLogs]

It also very confusing for me. but amazingly it works fine

[@badrinathmurugesan7375]

What problem did you faced before

[@824pavel]

To safely power the sim800 module with 5V, put a diode in series on 5V line, just before the capacitor. The cap can be 860-1000mF.

[@AhmadLogs]

thanks for sharing your knowledge

[@samrev292]

what's the value of the dioda exactly? Please

[@manikantaboddu2197]

​@@samrev292it may be IN4007?

[@dhanush4132]

in my case, i have used step down buck convertor and i had set it to 4v, it still facing the power issues(7 times blink and reset), then i have the increased the voltage to 4.35v still i had faced the power issue. but totally, i removed the step convertor and connected directly to 5v by using this capacitor trick. finally it worked!!!

[@shuyikhor6461]

May I know the sim card that you used is 4G?

[@СергейИванович-к7л]

it works!!! You are the best!

[@manikantaboddu2197]

Thank you Ahmad Bhai... It's solved my network issue SIM800L V2.0 module. But diode also required across capacitor?

[@saeidpourafshar4824]

Man this module is a pain in the arse, weird operating voltage range, 2A surges that needed to be handled with.. are there any better alternative for GSM/GPRS connection?

[@AhmadLogs]

try sim800L V2. (5v)

[@m.furqonrabbani7610]

how much the current of your usb laptop i am using usb that used to be phone charger but it fail

[@AhmadLogs]

usb is capable of provide enough current to the gsm module. also you can use 2A rating mobile phone charger, I have tested it.

[@cornel830]

Hello, did the same thing but mine doesn`t work, i have a 18650 3.7V battery connected to it and Arduino but id won t connect to network, tried everything, need help please! Without SIM card csq range between 29-31 when i plug the sim card, it sees it and csq is 0 0. I just don t understand

[@AhmadLogs]

try to change the sim card. or verify the sim card if it is working or not, by inserting it into the phone. only 2g sim card will work. try with another sim800l

[@samrev292]

Does it has a side effect for a long time use? Like damaging the sim modul as the example

[@AhmadLogs]

using a capacitor in parallel with the power supply of the SIM800L module can have some benefits, such as reducing the noise and ripple in the power supply, which can improve the performance of the module. However, it is important to choose the right value of capacitor and to properly install it to avoid any negative effects on the module. In general, using a capacitor in parallel with the power supply should not damage the SIM800L module, as long as the capacitor is correctly selected and installed. However, if the capacitor is too large, it may cause excessive inrush current when the module is first powered on, which can potentially damage the module. Similarly, if the capacitor is not installed properly, it could create a short circuit or other electrical problems that could damage the module.

what isa difference of method 1 and 2?

[@ranaaalihaider]

Ahmed bhai my module is blinking 10 times tried parallel capacitors and source from 3.7v to 4.2 volt but same problem previously it was showing same issue after 1 or 2 days but now its not going and issue is still there 2nd most important thing can we use sim800l in product for selling like is that reliable or it is just for demo projects

[@suzanaothman8552]

Hello sir, if I want to do GSM calling and my GSM blink non stop mean don't have enough power and the solution is capacitor 16v? And need to do command for calling and SMS if not doing that cannot work?Please sir I need your explanation for my project gsm laser security

[@AhmadLogs]

you need 3.7v and at least 2000mAh battery for powering sim800l. if your gsm blink non stop, then its mean that 1. there is some issue with your sim card that you have inserted in the module. 2. there is some issue with your gsm module antenna. 3. or your gsm module might be damaged. just try another sim800l

it is power supply issue. use 5v 2A power supply

[@manikantaboddu2197]

Use separate power supply for sim800l v2 and use 1000uf 6.3V capacitor across Vcc and gnd pins at module. It will work

[@101mobiles4]

Can we connect Neo-6m antenna to sim800l

[@AhmadLogs]

No, the Neo-6m GPS antenna cannot be connected directly to the SIM800L module. The SIM800L module does not have a GPS receiver built-in and cannot be used for GPS tracking without an external GPS module.

this is not a proper way to power sim800l. it is just a trick. you need proper power supply like 3.7v battery

[@adnanhabib6501]

this means we can connect directly to 5 volts????????

sometimes?
