Compare the connection at your actual address and for your own tasks. Include data limits, equipment and total cost alongside performance. A technology name alone does not prove which option will work better in your home.

Define the use before the package
List video calls, streaming, downloads and the number of devices used at the same time. Use your own usage records where available rather than an invented national average. Identify tasks that cannot wait and whether a temporary connection is enough. Keep portability as a separate requirement if you need connectivity away from home.
Check restrictions for both options
For fibre, verify address availability and installation. For mobile, check coverage, device compatibility and whether the package is restricted to a location or network. Afrihost’s Telkom LTE FAQ describes conditions for that named service [1]. Read data caps, fair-use rules and out-of-bundle treatment instead of interpreting an unlimited headline by itself.

Test and compare a real month
Where a legitimate trial or existing connection is available, test the tasks at the times you need them. Record problems without claiming that one test represents every user. Compare installation, equipment, monthly service and any extra data for the same month count. Ask about exit terms if the service cannot meet the requirement.
Build a task-based test sheet
Choose the tasks that matter and record when you need them, how many devices are active and what counts as an acceptable result. Where testing is possible, run the same task under each available option rather than comparing unrelated speed screenshots. Keep a problem with Wi-Fi coverage inside the home separate from an unanswered question about the internet service. Check what support the provider offers for the actual equipment and package. Compare the cost over the expected period and include additional data only where your own usage scenario needs it. A limited test is evidence for that test, not a guarantee for every future day.
A calculation you can check
Fictional three-month comparison: fibre setup R600 plus 3 × R500 = R2,100. Mobile equipment R400 plus 3 × R550 = R2,050, before any extra data. A R100 extra-data need each month changes mobile to R2,350.

Questions about this decision
Is fibre always faster?
Compare the actual package and observed service at the address. This guide does not assign a universal winner.
Does mobile coverage guarantee indoor performance?
Check the provider’s conditions and test your required tasks where possible. A coverage indication is not your measured indoor result.
Can I move a home LTE package anywhere?
Read location and device restrictions for the exact package. Do not equate every mobile-labelled product with unrestricted roaming.
What does unlimited mean?
Read fair-use, speed and other applicable conditions in the provider’s agreement.
Should I count equipment twice?
Separate owned equipment from new required purchases and check compatibility before reusing it.
How do I compare a capped package?
Add extra data needed for the same usage month using a real price, and note what happens when the cap is reached.
Is backup connectivity another full package?
Define the essential tasks and interruption duration first, then price a suitable supported option.
Where do I confirm the terms?
Use the provider’s current package and help pages with the network, address and date recorded.
