Fibre vs LTE: Why You Should Upgrade
Moving from 4G to light. We look at why fibre is a massive upgrade over traditional mobile data.
Fibre vs LTE: Why It's Time to Ditch the SIM Card
Executive Summary
For many South Africans, Fixed LTE was their first experience with "home internet." It was a great bridge technology, but in 2025, it is being rapidly phased out in favor of fibre. If you are still using an LTE router (4G), you are likely paying more for a slower, less stable connection. This guide explains why upgrading to fibre is the single best digital upgrade you can make this year.
The 3 Main Reasons to Upgrade
1. True Unlimited Data
Most LTE plans are "Capped" or have very strict "Fair Use" limits (e.g., 200GB). In a world of 4K streaming and 100GB game downloads, this is no longer enough. Fibre is truly uncapped, allowing you to use terabytes of data without worry.
2. Symmetrical Speeds
LTE is designed for downloading. Its upload speeds are often abysmal (1-5Mbps). Fibre offers symmetrical or near-symmetrical speeds, which is essential for the modern world of video calls and cloud storage.
3. Congestion-Free Performance
LTE towers are shared with every mobile phone in your neighborhood. During peak hours (6 PM - 9 PM), your LTE speed can drop to a crawl. Fibre is a dedicated physical line to your house, meaning your speed stays consistent regardless of how many people are online.
Comparison: Fibre vs. LTE
| Feature | Fixed LTE (4G) | Fibre |
|---|---|---|
| Avg. Speed | 10 - 30 Mbps | 50 - 1000 Mbps |
| Data Limit | Often Capped | Truly Uncapped |
| Stability | Low (Weather/Congestion) | Very High |
| Latency | 30ms - 60ms | 2ms - 10ms |
| Value (Price/GB) | High | Extremely Low |
Is LTE Still Useful?
LTE still has a place in 2025:
- As a Backup: Keep an LTE router for when the fibre line is physically cut (e.g., by a construction crew).
- In Remote Areas: If you live where there is no fibre and no 5G, LTE is your only affordable option.
- For Travel: A mobile LTE hotspot is great for holidays or working from a coffee shop.
Practical Checklist: Making the Switch
- Check for Fibre Coverage: Use our availability tool to see if the cables have reached you yet.
- Compare Monthly Costs: You might find that a 50Mbps fibre line is actually cheaper than your current LTE plan.
- Look for "Free Switch" Promos: Many ISPs will give you a free router if you switch from their LTE service to their fibre service.
- Cancel your LTE: Don't forget to give 30 days' notice to your mobile provider once your fibre is live.

Frequently Asked Questions
Can I use my LTE router for fibre?
Usually, no. LTE routers use a SIM card; fibre routers use an Ethernet (WAN) port to connect to the ONT box on your wall.
Is fibre cheaper than LTE?
Yes. If you look at the cost per Gigabyte, fibre is significantly cheaper. A R500 LTE plan might give you 200GB, while a R500 fibre plan gives you unlimited data.
How long does it take to switch?
You can order fibre today, and once it's installed (3-7 days), you can cancel your LTE. We recommend keeping both for a few days to ensure the fibre is stable.
