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
- Your phone no longer receives security updates.
- Coverage with your provider has been reliable.
- You want the process to be quick and simple.
- A trade-in on your existing handset improves the deal.
When switching makes sense
- Coverage has been a problem. The strongest reason, and one an upgrade locks in for another two years.
- Another provider prices your bundle meaningfully better.
- You want a handset your current provider does not stock.
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.
