Tutorial 3 | Make a PPP internet connection with 3G, 4G/LTE Shields on Raspberry Pi [OUTDATED]

#Note: The new PPP installer Tutorial is Available now. LINK to the tutorial

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 3G-4G/LTE PPP Internet connection, we will use Quectel UC20 3G module or Quectel EC25 4G/LTE module, which are series of powerful function UMTS/HSPA+ module and series of LTE category 4 module optimized specially for M2M, IoT and multimedia applications respectively. 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.
