MPN move to another o2 account

[SMc17]

I’m an o2 and Virgin customer and my husband is an o2 customer too. We want to migrate my husbands mobile number to a SIM only contract on my o2, so that he gets the Volte benefits. Any idea how we do this? Tia

Everyone at the same address gets Volt.

No need to change anything.

Bigger benefits - Volt

If he wants to upgrade ::

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 the 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+
