 ### Cellular Connectivity
-The **Arduino® Portenta Cat. M1/NB IoT GNSS Shield** provide access to various cellular networks via the TX62-W Module (U1). It is possible to connect an external cellular antenna via a micro UFL connector (J7). Both SMS and data transfer functionality is are provided. SMS messages can be stored in the SIM card module.  The modem is addressable via AT commands. Modem status is provided by the RGB LED (DL1).

 ### Requirements
 
-The GSM Feature requires:
-* An antenna (e.g [Dipole antenna, at the arduino store](https://store.arduino.cc/products/dipole-pentaband-waterproof-antenna?queryID=52d9fdab80e7fcace62aae924c084a93&_gl=1*msh8uc*_ga*MjA5OTMyMzAwMC4xNjIxNTE1OTY3*_ga_NEXN8H46L5*MTYzMDkzMzQ3NS40NS4xLjE2MzA5MzM5MTAuMA..)) at the **RF OUT** antenna connector on the top side of the shield.
+The GPS Feature requires:
+* An antenna (e.g [Dipole antenna, at the Arduino store](https://store.arduino.cc/products/dipole-pentaband-waterproof-antenna) at the **RF OUT** antenna connector on the top side of the shield.
 * SIM Card capable of running with the CatM1 specifications  (check with your provider if your Card has that feature)
 
 To check if our setup it's working we can open an example sketch from the GSM library inside the Mbed Portenta Core. Under **Examples > GSM > GSMClient** we open a sketch that connects to the SIM card provider, then connects to a webpage and downloads the content of it to display it inside the Serial Monitor.
