3G, 4G, and 5G for IRL streaming
You want to know which network to trust before you go live. The network your phone is on shapes your stream, and 3G, 4G, and 5G each have a moment to shine. Your phone runs one SIM's data at a time, so this is a choice you genuinely make rather than one the app makes for you. Here is when to reach for each, in plain English.
The quick version
- 3G: slower, but it can hold a steadier connection in awkward spots.
- 4G: the everyday workhorse, fast and available almost everywhere.
- 5G: much faster, and the best pick in a crowd, especially mmWave.
3G, for stability when it counts
3G is old and slow by today’s standards, but the radio waves it uses travel further and hang on where faster networks wobble. That makes it a surprise hero when you need a steady link that sends less data (a low-bitrate link, where bitrate is how much data your stream sends each second) more than raw speed. It is the trick behind some wild streams, including going live from a helicopter, where staying connected matters far more than going fast. Drop your bitrate to match, and 3G just holds.
4G, the everyday workhorse
For most streams in most places, 4G is the sweet spot. It is fast enough for a clean 720p or 1080p, and it is available almost everywhere you will want to stream. If you are not sure what to use, use 4G.
5G, speed and crowds
5G is a big step up in speed, and its real superpower is capacity. In busy places where everyone’s phones are fighting over the same towers, like festivals, stadiums, and packed city centres, 4G clogs up and streams stutter. 5G has far more room, so it stays fast exactly when you need it most.
A word on mmWave
5G comes in two broad flavours. The common one uses lower frequencies for wide coverage and a solid speed bump. The other, mmWave (millimetre wave), uses very high frequencies for enormous speed and capacity, but only over short distances and with a clear line of sight to the mast. Where you can get it, mmWave is fantastic in dense crowds, as long as you stay close to a node (a nearby 5G transmitter).
How to choose, and why bonding helps
- Stable but slow spot, or up in the air? Try 3G and lower your bitrate.
- A normal day out? 4G.
- A big crowd or a dense city with 5G? Use it, and mmWave if you can reach it.
Because Super Simple IRL bonds connections, you do not always have to bet on a single network. Your phone can carry Wi-Fi and its mobile data at the same time, and a second phone on the same Wi-Fi network adds a second carrier. One phone alone cannot run two SIMs at once, so on a bare walk with no Wi-Fi the network you pick is the network you get. See what is bonding for how the links work.
Frequently asked questions
Which is best for IRL streaming, 3G, 4G, or 5G?
For most streams, 4G is the sweet spot of speed and coverage. Reach for 3G when you need stability in an awkward spot, and 5G when you need speed in a crowd.
Why would I ever use 3G?
When you need a steady, low-bitrate link more than raw speed, such as high up in a helicopter or far from towers where faster networks get flaky. It is slower, but it holds on.
What is mmWave 5G?
mmWave, or millimetre wave, is a very high frequency flavour of 5G with huge speed and capacity over short distances. It is brilliant in dense, crowded places like stadiums and city centres, as long as you are close to a node.
Can I use more than one network at once?
Yes, with a second device. A phone uses one SIM's data at a time, so the app bonds its mobile data with Wi-Fi, and a second phone on the same Wi-Fi network joins as an extra link on its own carrier. See what is bonding.
