Official Cell C contract route
Cell C lists 084 145 as its Contracts & Upgrades line on its contact page, and its upgrade page asks you to call 084 145 so a consultant can help with your upgrade. The same number is listed for Cell C Direct. Calls from any other network or a Telkom line are charged at normal rates.
Some older Cell C FAQ text still points to 084 143 or 143 for upgrades. Cell C’s contact and upgrade pages both give 084 145, so use that number.
If you would rather be called, the contracts page at cellc.co.za/cellc/contracts has a call back form: enter your name and mobile number and Cell C says it will call you shortly. Business customers looking for contracts use Business Sales on 084 1234.
Contract deals and upgrade support
The contract deals page lets you filter device contracts by 24 or 36 months and by price band. For quick product and service information from a Cell C phone, dial 147.
If you upgrade in a Cell C store or an approved outlet, you get the device immediately when it is in stock. Upgrades done through the call centre are delivered within 3 to 7 working days. Upgrade call backs come from 084 135 and include a reference number, so you can tell a genuine Cell C call from a stranger.
Eligibility and account requirements
You can check whether you are due for an upgrade in three ways: dial *147*9# from your Cell C phone, use the online eligibility checker at cellc.co.za/cellc/upgrade, or call 135 and choose option 1 (Manage) and then option 4 (Upgrade Eligibility).
Cell C’s upgrade windows are:
- 6-month contract: end of month 6
- 12-month contract: month 11
- 18-month contract: month 16
- 24-month contract: month 21
You must show proof of identity before upgrading. For RICA you need a green bar-coded ID book, Smart ID card or passport, plus proof of address not older than 3 months.
How to get a Cell C contract or upgrade
- Check your eligibility: dial *147*9# from your Cell C number, use the online checker, or call 135, option 1, then option 4.
