[Updated] Tutorial 3 | Make a PPP internet connection with 3G, 4G/LTE Shields on Raspberry Pi

Previously we have used GPRS shield to establish internet connection. Now we will use 3G, 4G/LTE shield for PPP internet connection. In order to make a 3G and 4G connection we will need to use Quectel UC20 and Quectel EC25 modules respectively.

As this tutorial is for 4G PPP Internet connection, we will use Quectel EC25, which is a series of LTE category 4 module optimized specially for M2M, IoT and multimedia applications. Due to rich set of protocols, industry-standard interfaces and abundant functionalities extend the applicability of the module ti a wide range of M2M and IoT applications such as industrial router, industrial PDA, rugged tablet PC, video surveillance and digital signage.
