 ## Introduction 
 
-The Portenta Max carrier adds a lot of functionality to the Portenta H7. With the Portenta Max Carrier it is possible to use NB-IoT and Cat-M1 technology. In this tutorial we will show to connect to GSM with the Portenta Max carrier and the Portenta H7.

 ### Circuit
 
-For this tutorial we need to plug the Portenta H7 into the Max Carrier, like shown in the image below. By attaching the Portenta H7 board to the HD connectors on top of the Portenta Max Carrier. Press firmly to let it snap in. Once attached, plug the Portenta H7 into your computer using a USB C cable.

-And we also need to insert a SIM card and connect an antenna to the Max Carrier, like shown in the image below. Put the SIM card into the SIM card slot at the top of the Carrier, the same side where the Portenta H7 is located. Next to the SIM card slot there is an antenna SMA connector where you will need to screw on your antenna.

 ## Conclusion
 
-In this tutorial we went through how to connect the Portenta H7 and Portenta Max Carrier, with peripherals to be able to use the carriers GSM feature. We then learned how to set a preference between NB-IoT or Cat-M1 technology. And at the end we tested so everything works by running an example sketch on our setup.
