Best 30GB data deals in South AfricaNovember 2026
A practical comparison for people who want roughly 30GB this month. Every restricted wallet and eligibility condition stays visible, so a split bundle cannot masquerade as 30GB of general daytime data.
Quick verdict
MTN is our best overall 30GB pick
Super Data 30GB provides 30GB of pooled anytime data for R269, or R8,97 per anytime GB. 30GB is available as one pooled anytime allowance.
Eligibility: New or existing MTN prepaid customers must migrate to the Super Data price plan.
Before switching to or from Super Data
Moving to Super Data forfeits Bonus Bonanza “Recharge and Get” and any other benefits from your previous price plan. Moving away forfeits unused, unexpired Super Data and Voice bundles.
This is a price-and-structure result, not a coverage or speed claim. Check signal where you live, work and travel before moving networks.
Best unit value: Standard Bank Connect offers 35GB for R299, or R8,54 per anytime GB.
Like-for-like view
30GB-class offer comparison
Rows marked “context only” are current and useful, but do not enter price awards because the validity, product bundle or restriction makes the price non-comparable. All R/anytime-GB calculations exclude night, streaming, social and daily-release wallets.

How DataCost counts 30GB
Pooled anytime
A general-use wallet available as one monthly pool. Daily releases remain separate even when each daily slice works throughout the day.
Night
Data usable only in the provider’s overnight window. It counts toward the advertised total, not the anytime target.
Streaming or social
App- or service-specific wallets stay separate because they cannot support every normal internet task.
Other restrictions
Daily releases, device locks and conditional bonuses get their own fields and never disappear inside a headline number.
Why this ranking is editorial, not commercial
DataCost does not raise an offer because it has a bigger advertising number, includes an affiliate opportunity or comes from a major network. Every qualifying row follows the same deterministic order.
1Guaranteed pooled anytime data must fall from 30GB up to, but not including, 50GB.
2Validity must be 28–31 days or an explicitly monthly allocation.
3The source and price must be current, official and publicly reproducible.
4Best overall uses the lowest monthly price; ties use fewer access restrictions, then once-off billing. Unit value is awarded separately.
This public URL stays evergreen. Each monthly review is stored as a separate internal snapshot, so updating September’s prices will not erase the August evidence. The visible month, checked date, source register and structured data all come from the same active snapshot.
A provider may change a checkout price between reviews. If the price or eligibility shown here differs from the official checkout, use the provider’s current terms and tell DataCost so the next review can correct the record.
