Fibre vs LTE: which is right for you?

Both get you online — but they behave very differently. Here’s how to choose without overpaying.

If fibre reaches your home, it’s almost always the better long-term choice. But LTE and 5G still win in specific situations — and knowing which you’re in can save you thousands a year.

Speed & consistency

Fibre delivers the speed you pay for, around the clock. A 100 Mbps fibre line gives you close to 100 Mbps at 8pm on a Sunday just as it does at 3am. LTE is shared — your speed depends on how many people are on the same tower, so it sags during peak hours.

Cost

Rand for rand, fibre is cheaper per gigabyte by a wide margin once you use more than ~50GB a month — which most households do in a single weekend of streaming. Uncapped fibre from around R400/month replaces both a capped LTE plan and the anxiety of running out.

Rule of thumb: if you work from home, stream in 4K, game online, or have 3+ people sharing — get fibre if you can. If you move often, rent short-term, or fibre simply isn’t on your street yet, LTE/5G is the sensible bridge.

The verdict

Check coverage first. If a network is live at your address, compare fibre deals before defaulting to mobile data — you’ll usually get more speed, no caps, and a lower bill. If nothing’s live yet, a 5G router is a great stopgap until the trenches reach you.
