Switching networks involves two things that people tend to run together: porting your number, and exiting whatever you are on now. The first is straightforward. The second is where the cost sits.
Establish the exit cost first
If you are mid-contract, early cancellation normally carries a settlement charge covering the outstanding device value. That figure frequently outweighs whatever you would save by moving.
Get it in writing before doing anything else. If you are within a few months of the end, waiting is usually cheaper than switching now.
Then check the destination properly
Switching only makes sense if the new network genuinely works where you are. Test with a prepaid SIM across your normal routine — home, work, commute — before committing to another term.
This matters more when switching than when starting fresh, because you are giving up something that presumably functions. See check coverage before a phone contract.
Porting, in order
- Apply for the new contract or SIM-only plan.
- Request the port during the application, giving your existing number.
- Keep your current service active.
- Confirm the new SIM receives calls on your number.
- Only then close the old account.
Cancelling first is the mistake that causes real damage — a closed account can mean losing the number, and recovering it is far harder than porting was.
Check your handset
If you are keeping your phone, it must be unlocked and support the new network’s bands. Handsets bought on contract are sometimes locked until that term completes.
Good and bad reasons to switch
| Good reason | Weak reason |
|---|---|
| Coverage has been genuinely poor | A promotional price that expires |
| You have moved and the network no longer suits | Marginal monthly saving |
| Your data needs changed substantially | Wanting a new handset mid-term |
If you want a new phone rather than a new network, an upgrade with your current provider is usually simpler. See upgrade vs new phone contract.
