How to Buy Telkom Data: USSD, App, Voucher & Bank Options
Start with the Telkom buy-data route that matches your situation: USSD when you have no data, the Telkom app when you want a clearer bundle view, vouchers or banking apps when you are topping up from outside the Telkom menu, and airtime when you already have prepaid credit available.

Ways to Buy Telkom Data
Option 1: Buy data with Telkom USSD
Dial *180# from your Telkom SIM, choose the current data action shown, then compare the available bundle sizes and validity periods. USSD is useful when you do not have active mobile data.
Option 2: Check Mo'Nice-style personalised offers
Dial *123# where available and compare any personalised Telkom offers against the standard *180# menu. Treat these as account-specific promotional offers, not guaranteed public prices.
Option 3: Use the app, vouchers, banking apps, or airtime
Use the Telkom app when you want a fuller bundle breakdown, load a voucher when you have a recharge PIN, or buy through a supported banking app. If you already have airtime, confirm the final price and validity before converting it into data.
Common Telkom Data Buying Mistakes
Assuming every personalised offer is available to every SIM
Mo'Nice-style offers can vary by account profile and campaign period. Check what your own line shows before planning around a specific deal.
Buying before checking balance and validity
Check current airtime, data balance, and expiry first so you do not duplicate a bundle or lose value on a short-validity offer.
Choosing the lowest price without matching use case
Daily, night, social, and monthly bundles serve different needs. Compare price, validity, and where the data can be used before buying.
