Also, you might want to take a look at this library…

BlynkGSM_Manager

This is the new library, adding to the current Blynk_WiFiManager. It’s designed to help you eliminate hardcoding your Blynk credentials in ESP32 and ESP8266 boards using GSM shield (SIM800, SIM900, etc). You can update GSM Modem and Blynk Credentials any time you need to change via Configure Portal. Data are saved in SPIFFS or configurable locations in EEPROM. If it cannot connect to the Blynk server in 30 seconds, it will switch to Configuration Mode. You will see your built-in LED turn…
