Welcome to the range of Cellular Arduino shields from PMD Way.
Your Arduino can communicate via a mobile phone (cellular) network! Ideal for sending and receiving SMS text messages with data, instructions, alerts and more. (Please click here if you need a Cellular device for your project but not in Arduino shield format!)
Please note that not all shields will work in all areas. You need to find out from your intended mobile telephone network if they are a 2G or 3G network - and which frequency they use. Then match that data against our shield specifications to make sure you get the right one.
If you need any help choosing the right shield for your task - first, get your network information as mentioned above - then email it to email@example.com and we'll guide you to the correct cellular shield for your Arduino.
