15 Nov

While an acronym sometimes is techno babble the layperson needn’t master, others are important for everyday cell phone understanding.
Though the jargon 1G, 2G, 2.5 and 4G might not have ever popped into your head, 3G very likely has given today’s emphasis on high-speed data usage from your mobile phone.
But what’s different between these technologies and how do they impact you? This article will help you understand the differences between 1G vs. 2G vs. 2.5G vs. 3G vs. 4G.
