Transfer SIM to SIM Only Deal

[JoshG97]

I'm now out of my previous contract with O2, and have found a cheaper SIM only deal with O2. How do I transfer my existing number to this, and ensure I don't continue paying the one I'm now out of contract on?

I tried calling them but it was no help, and the person didn't seem to understand what I was asking for. Thanks!

Use USwitch

https://www.uswitch.com/mobiles/compare/sim_only_deals/o2/

Choose the deal you want

This will automatically redirect you to the O2 website

Just follow the prompts and choose the UPGRADE option

Complete the deal and nothing on your account changes except the tariff at the new cheaper cost

Payment date is the same and your next bill will be at a cheaper rate and will be made up of the pro rata cost of your old tariff and your new tariff

The change should show in My O2 within 24 hours

Volt benefits will still apply as will possibly a 3 month extra such as Disney+

Just seen this as I want to change, unfortunatley the smallest option is 32Gb at £8 per month. Think i will go to Lebara.

Always pays to compare deals, @nickw - good luck!
