WiFi is a networking standard that offers indoor fixed-location internet connectivity. It is similar to LTE in that it needs a data provider, but differs from LTE in that it also needs a router or other wireless transmission-capable device.
GSM makes use of both third-generation (3G) and second-generation (2G) communication standards. LTE is limited to using fourth generation (4G).

The main benefit of combining the ESP32 with the GSM Module is that, if you have an internet connection and the ESP32 module is connected with WiFi, you can use the Blynk application or any other IOT Platform to watch the sensor data in real time from anywhere in the globe. You will also be able to...
LTE is the de facto industry standard for 4G wireless connectivity that facilitates high-speed data delivery. Contrarily, the 2G and 3G networks use the CDMA technology for communication. Due to its ability to utilize the available bandwidth to the fullest without significantly increasing disturbance, CDMA was widely used.
