10 Smartphones with the Fastest Internet in 2024

Today, most smartphones support the 4G network. This network is much faster than older networks. But now, there's an even newer technology called 5G, or Fifth Generation.

5G networks are the latest and offer internet speeds that are way faster than 4G. Some smartphones with 5G modems can even reach download speeds up to 7 Gbps! To understand more about 4G and 5G, you can read about the different types of mobile networks in the article "Types of Mobile Networks from Generation to Generation."

In this article, Carisinyal will talk about several smartphones that support both 4G and 5G technology and have incredible internet speeds.

Before we start, here's a disclaimer. This list of fast internet smartphones does not mean these phones will always provide fast internet. The internet speed also depends on whether the network in the area is good. The mobile operator plays a big role in this.

Also, this list is based on information from websites that claim to have tested these phones. What are these phones?
