Mobile broadband refers to wireless internet access you can get by using your phone as a modem.

It happens when cellular towers transmit internet access and your phone picks up the signal. Your mobile broadband connection happens behind the scenes, and it’s why you can scroll through Facebook and Instagram even when you’re not connected to Wi-Fi.

Your mobile broadband connection will either be a 3G, a 4G, or eventually a 5G connection.

What’s the difference between 3G, 4G, and 5G?

Here’s something you probably never knew—the “G” stands for generation. (So simple, yet so profound.) The more G’s you have, the faster your internet speed will be. Here’s a breakdown of what speeds to expect with each generation:

0.1 Mbps


42 Mbps

8 Mbps


1 Gbps

50 Mbps


10 Gbps


The older the network, the more it will struggle meeting the demands of our internet use. It’d be like trying to play Fortnite on a Windows XP operating system. (Your poor computer.)

But what if you don’t want to part with your beloved oldschool iPhone that runs on a 3G network? It might still meet your needs now, but it won’t soon. Take a look at the latency you can expect with older mobile broadband connections:

Latency (milliseconds)









Yes, we are dealing with milliseconds here, but we both know how annoying it can get waiting for the internet to load. How many of us have been in the awkward situation of showing someone a video and the connection craps out on us? Filling that silence is always uncomfortable.

(Not to mention how much harder it’ll be to check email and social media.)

Bandwidth vs. latency

Bandwidth refers to how much data your internet connection can upload or download at one time. Latency is a measure of time delay and refers to how much time it takes your computer to send and receive signals.
