Cost per GB = bundle price divided by the listed general-use GB. Social and router products are excluded; a night bonus is shown separately and does not remove the anytime allowance; an empty network row means no matching recorded bundle, not that the operator sells no monthly data. The checked dates beside the rows describe the pricing evidence; the page update date describes the editorial changes.
What to watch out for
Monthly value differs sharply by bundle size, so compare like-for-like usage levels.
Recurring bundles may auto-renew, which can drain airtime if not monitored.
A cheaper monthly offer is only valuable if your local coverage is dependable.
Practical savings advice
Compare the total you would spend on repeated top-ups over the same period, allowing for data that expires unused.
Check whether your line shows a personalised monthly offer and compare its full terms with the public menu.
Review expiry and renewal settings so you do not lose value through rollover assumptions.

Frequently Asked Questions
Which network gives the best monthly data value in South Africa?
There is no single winner for every allowance and eligibility requirement. The quick picks here apply only to the selected once-off smartphone bundles in this table. Use the dedicated 10GB, 20GB and 30GB monthly comparisons for larger allowances, with night data, daily-release data and bank-account requirements shown separately.
Are monthly bundles always better than daily bundles?
No. Compare the total cost for the same usage and period. A daily bundle may suit an occasional top-up; a monthly allowance may suit use spread across the month. Data that expires before you use it reduces the practical value of either option.
How do I choose the right monthly bundle size?
Base the decision on your average month: messaging and browsing vs heavy streaming and hotspot usage. Avoid buying too small and repeatedly topping up.
What should I watch out for on recurring monthly bundles?
Check auto-renew rules and available airtime behavior. Recurring bundles can be convenient, but only when renewal settings are understood.
