+A number of Arduino boards are able to connect to the Arduino Cloud using a sim card, using either the GSM or LTE-M (Cat-M1) technologies.
 
 ## Supported Boards
 
 - [MKR GSM 1400](https://store.arduino.cc/arduino-mkr-gsm-1400)
 - [MKR NB 1500](https://store.arduino.cc/arduino-mkr-nb-1500-1413)
 
-Connection through mobile networks can be considered in remote areas where there's no Wi-Fi, or in mobile projects (such as cargo tracking).

 ***For more information, visit the [Arduino SIM page](https://store.arduino.cc/digital/sim).***
 
 ***Note that a secured connection is a memory intense operation, so there's not a lot of memory for the user application (e.g. around 2.6 kB on the MKR GSM 1400). Using a lot of Arduino Cloud variables may cause the sketch to run out of memory on boards which don't offload the SSL stack and make it crash.***
 
 ## Setup
