Do my payments reduce when my contract ends as I have paid off the handset?

[RJ72]

I am paying about £30 per month for handset and usage. 

Contract ends this month. Will my payments reduce as the handsety is paid off?

@RJ72 Yes, you will only pay for the air time once your contract is finished. If you're happy keeping the phone you have, you can then also look for a sim only tariff that may be better than your current air time tariff.

If you are making two separate payments then yes it works as @Bambino has advised.
If you make a single payment, then no it will not.
If a single payment, once your final bill has been paid you can then upgrade to a sim only deal (like I did).
Depending on the deal you choose it should reduce your payment.

Good info above from @Bambino and @gmarkj , hope you got all you needed @RJ72 but don't hesitate to come back to let us know if you need anything else.
