In an era where reliable, unlimited internet is a household necessity, navigating South Africa’s competitive broadband market to find genuine value requires a careful analysis of speed, stability, and true cost. “Cheapest” must be qualified by understanding the technology used—Fibre-to-the-Home (FTTH), fixed-LTE, or 5G—and the nature of the “uncapped” offer, which can range from truly unrestricted to “soft-capped” or “shaped” after a certain threshold.
This guide details ten of the most affordable uncapped WiFi deals available nationally, providing a clear breakdown of their pricing, speed profiles, and key limitations to help cost-sensitive consumers make an informed decision that balances monthly expenditure with practical usability for browsing, streaming, and remote work.
10 Cheapest Uncapped Wifi Deals In South Africa
Deal 1: RSAWEB Fibre – Home Uncapped 10/5 Mbps
A competitively priced entry-level fibre plan from a established provider, targeting light users and small households.
Monthly Price: R297
Speed & Technology: Symmetrical 10 Mbps download and 5 Mbps upload speed on a Fibre-to-the-Home (FTTH) connection. This requires pre-existing fibre infrastructure in your area.
Data Policy: Truly unshaped and uncapped, with no Fair Usage Policy (FUP) that throttles speeds. It is a pure, unthrottled connection suitable for consistent light use.
Ideal For: Single users or couples whose primary needs are web browsing, email, social media, and standard-definition (SD) video streaming on one device at a time. It is the baseline for affordable, stable fibre.
Deal 2: Cool Ideas Fibre – Access 10/5 Mbps
Another major fibre provider offering a nearly identical low-cost entry point into the fibre market with a strong reputation for customer service.
Monthly Price: R307
Speed & Technology: 10 Mbps download / 5 Mbps upload on an FTTH network.
Data Policy: Uncapped and unshaped. Like RSAWEB, Cool Ideas offers a premium, no-throttling policy on all its fibre lines, ensuring consistent performance at the advertised speed.
Ideal For: Budget-conscious users in fibre-ready suburbs seeking a reliable provider for basic internet tasks. It is comparable to Deal 1, with choice often coming down to which provider has a better relationship with the local Fibre Network Operator (FNO).
Deal 3: Afrihost Fixed LTE Uncapped
A wireless alternative for areas without fibre, using the MTN LTE network with an installed router.
Monthly Price: R449
Speed & Technology: Fixed LTE with average speeds of 10-20 Mbps. Performance is dependent on MTN network coverage and signal strength at your specific address.
Data Policy: Uncapped but subject to a Fair Usage Policy (FUP). After consuming 300GB of high-speed data, speeds may be managed during network congestion. Not suitable for 24/7 heavy downloading.
Ideal For: Homes in non-fibre areas needing an uncapped solution. Good for moderate streaming and browsing, but variable speeds and the FUP make it less consistent than entry-level fibre.
Deal 4: Telkom LTE-A Uncapped
A competitive wireless offering from Telkom, leveraging their LTE-Advanced network for improved performance over standard LTE.
Monthly Price: R499
Speed & Technology: LTE-Advanced, offering potentially better speeds and stability than standard LTE, but still entirely dependent on Telkom tower coverage.
Data Policy: Uncapped with an Acceptable Use Policy. Similar to other LTE offers, extremely high usage may lead to prioritisation during peak times. It includes a WiFi router.
Ideal For: Telkom network coverage areas where fibre is not available. A strong option if your location gets a strong, stable Telkom signal, offering more value than standard LTE for a small premium.
Deal 5: Vox Telecom Fibre – MoreLink 10/5 Mbps
A value-oriented fibre plan from Vox, which operates on various open-access fibre networks across the country.
Monthly Price: R339 (often with promotional discounts for first 3-6 months)
Speed & Technology: 10 Mbps download / 5 Mbps upload on FTTH.
Data Policy: Uncapped and unshaped, providing a stable, no-throttling experience at the entry-level speed tier.
Ideal For: Shoppers comparing the baseline fibre market. Vox frequently runs aggressive sign-up promotions, making the effective cost for the first half-year very low.
Deal 6: Axxess DSL Uncapped 10 Mbps
A legacy copper-line (ADSL) offering, remaining an option in areas still without fibre or stable LTE coverage.
Monthly Price: R399 (plus Telkom line rental of ~R200)
Speed & Technology: Up to 10 Mbps on a copper ADSL line. Requires an active Telkom telephone line.
Data Policy: Uncapped and unshaped. DSL is a stable technology, though maximum speeds are distance-sensitive from the exchange and lower than fibre/LTE.
Ideal For: Users in older suburbs with reliable copper lines but no other infrastructure. The total cost (R399 + R200 line rental = ~R599) is higher than fibre for slower speeds, making it a last-resort uncapped option.
Deal 7: Supersonic Fixed Wireless Uncapped (on MTN)
A pure-play wireless internet service provider (ISP) offering competitive fixed wireless packages.
Monthly Price: R477
Speed & Technology: Fixed wireless on the MTN network. Includes a free router. Speeds are advertised as “up to 20Mbps” but vary with signal.
Data Policy: Uncapped with a FUP. Typically includes 300GB of high-speed data before potential network management applies.
Ideal For: Those seeking an alternative to Afrihost or Telkom in the LTE space. Supersonic often bundles value-adds like streaming service trials, enhancing its appeal.
Deal 8: Mweb Fibre – Simply Uncapped 10/5 Mbps
A legacy ISP with a strong reputation, offering a straightforward entry-level fibre product.
Monthly Price: R347
Speed & Technology: 10 Mbps download / 5 Mbps upload on FTTH.
Data Policy: Uncapped and unshaped, aligning with the standard premium fibre offering at this speed tier.
Ideal For: Customers who value brand familiarity and bundled support. Mweb is a well-established name, providing confidence for those new to fibre contracts.
Deal 9: Rain 5G Unlimited
A disruptive mobile data product offering truly unlimited data on Rain’s 5G network, usable as a home WiFi solution with a compatible router.
Monthly Price: R479
Speed & Technology: 5G mobile data. Crucially, requires excellent Rain 5G coverage at your address. Speeds can exceed 100Mbps where coverage is strong.
Data Policy: Truly unlimited, with no FUP or throttling. However, speeds are not guaranteed and fluctuate with network congestion, unlike fibre.
Ideal For: Technically savvy users in a proven Rain 5G zone. It offers incredible speed potential at a low price, but the variability and coverage dependency make it a high-reward, higher-risk option compared to fixed lines.
Deal 10: MetroFibre Networx – 10/10 Mbps Uncapped
A direct offer from a Fibre Network Operator (FNO), often available in areas where they have laid their own fibre.
Monthly Price: R349
Speed & Technology: A symmetrical 10 Mbps download and upload connection on their own FTTH network.
Data Policy: Uncapped and unshaped. Buying directly from the FNO can sometimes provide a more stable service with lower latency.
Ideal For: Residents in a MetroFibre-serviced area. It eliminates the ISP middleman, potentially simplifying support and offering a robust connection at the low-end price point.
Critical Evaluation and Comparison Table
Choosing the best deal requires a direct comparison of the core value metrics: price, speed stability, and reliability.
| Provider & Deal | Tech | Promo Price | Speed (DL/UL) | “Uncapped” Type | Best For |
| :— | :— | :— | :— | :— | :— |
|RSAWEB Fibre 10/5 | FTTH | **R297** | 10/5 Mbps | **Truly Unshaped** | Absolute cheapest, stable fibre |
|Cool Ideas Access | FTTH | **R307** | 10/5 Mbps | **Truly Unshaped** | Reliable, customer-focused fibre |
|Afrihost Fixed LTE | LTE | R449 | 10-20 Mbps (varies) | FUP (300GB Hi-Speed) | Non-fibre areas, moderate use |
|Rain 5G Unlimited | 5G | **R479** | 20-150Mbps (varies) | **Truly Unlimited** | Homes with proven 5G coverage |
|Telkom LTE-A | LTE-A | R499 | Varies | Acceptable Use Policy | Strong Telkom signal areas |
Final Decision Framework:
1. Check Fibre Coverage First: Always use ISP websites to check if FTTH is available at your address. If yes, a sub-R350 plan like RSAWEB or Cool Ideas offers unbeatable value and stability.
2. If No Fibre, Test Wireless Coverage: For LTE/5G deals, confirm network strength. Rain and Telkom offer coverage maps. Order a free Rain 5G SIM to test before committing.
3. Understand the “Uncapped” Fine Print: Fibre is generally unshaped. Wireless deals (LTE/5G) almost always have FUPs or network management; clarify the high-speed threshold.
4. Calculate Total Cost of Ownership: Include once-off costs: router (often free on LTE contracts), installation (fibre install can be free or cost R1000+), and any mandatory line rental (for DSL).
By applying this framework, the “cheapest” deal becomes the one that provides adequate, reliable speed for your household’s needs at the lowest sustainable monthly cost, making options like RSAWEB Fibre at R297 or Rain 5G at R479 (where viable) the most compelling starting points for budget-focused South Africans.
