Cell C contract deals online application
The online route for Cell C contracts is the contract deals page at cellc.co.za/cellc/contracts. It lets you filter device contracts by 24 or 36 months and by price band, and each deal carries a “Get this deal” or “Buy now” button that starts the order on Cell C’s site. Cell C notes on that page that the deals are only available to new and upgrading customers.
If you would rather be called, the same page has a call back form: enter your first name, last name, email address and mobile number and Cell C says it will call you shortly. The form gives you a reference number once it has been submitted, so keep it.
Cell C contract deals contact number: 084 145
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.
Business customers looking for contracts use Business Sales on 084 1234. For quick product and service information from a Cell C phone, dial 147.
Checking when you can upgrade your Cell C contract
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
What you need to apply: ID and RICA
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. Have these ready before you start an application or take a call back, so the order is not held up.
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.
- Choose a deal on the contracts page or request a call back there.
- Upgrade in a Cell C store or call 084 145.
- Have your proof of identity, and proof of address for RICA, ready.
Delivery times and Cell C call backs
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.
Problems with an existing Cell C contract
Cell C does not publish a separate escalation line for contract sales. For problems with an existing contract, call customer care on 135 from a Cell C phone or 084 135 from another network.
