ESP32 with GSM Sim900, ESP32 & GSM, GSM Wifi, text message & Blynk App, IOT GSM,esp32 project

I Have a one doubt...is there no necessary for creating object for softserial SIM900A

can it still connect if i left the device far away from me?

Hello can you help me I used sim900a module and esp32 board

The module is not connect to network the b6 led blinking fast. Please help

How do you power this module while you're away from home?
I'm able to power this module and make gsm connection only with 5v 2amp adapter.
I want to make it portable.

Bringing together the ESP32-CAM + GSM SIM Board + a solar panel to have an autonomous web cam. Could that work?

will GSM work with 4g sim?

Does sim900 work with 3G or 4G networks?

Does this have to connect to an Access Point to send messages ? I see in the Sketch that you have put in the
char ssid[ ]
char pwd[ ]

Are you connecting it to a Wireless Router / AP ? before it is sent to the Blynk broker / cloud.

My project does not have any WirelessRouter nearby, and this unit has to connect to the Coud/Blynk in your case direct over the SIM card.

Can you send a WhatsApp Message ?

Awesome ♥

Can we use SIM800A instead of SIM900A?
If yes, what are the changes that we need to make?
Please help!
