When a contract ends you have three options, not two: upgrade with your provider, start fresh elsewhere, or drop the handset entirely and move to SIM-only. The third is usually cheapest and the most often overlooked.

Direct comparison

Upgrade New contract elsewhere SIM-only
Process Simplest — provider has your history Full application Simple, lower threshold
New handset Yes Yes No
Cost Similar to a new contract Similar Substantially lower
Change network No Yes Yes
Keep your number Yes Yes, by porting Yes

Start with the question that saves most

Does your current phone still receive security updates, and is the battery holding up? If yes, moving to SIM-only is the largest saving available to you at that moment, because the handset is already paid off and you stop financing one.

People upgrade by default at end of term without asking this. See SIM only vs phone contract and SIM only deals.

When upgrading makes sense

When switching makes sense

Number portability applies, so switching does not cost you your number. Compare on networks and cheapest network for phone contracts.

The trap in doing nothing

If you let a contract roll over, many agreements continue at the same rate — meaning you keep paying device financing on a phone you own outright. Doing nothing is the most expensive of the four options.

Frequently asked questions

Is upgrading cheaper than switching?

Pricing is broadly similar. Upgrading is simpler; switching lets you change coverage.

Can I keep my number if I switch?

Yes. Number portability applies across South African providers.

What is the cheapest option at end of term?

Moving to SIM-only and keeping your current phone, provided it still receives updates.

What happens if I do nothing?

Many contracts continue at the same rate, so you keep paying for a device already paid off.
