Hi Spacebucks,
Thanks for your post and it's great to hear you're able to benefit from a speed boost under our Volt offer.
As mentioned above, you would get a new hub to allow us to activate the speed boost.
You will still need to join in the same way though. Just log in to your O2 online account where you will be able to opt in to the benefits. Once you've done this, O2 will apply the data boost to your SIM and we will reach out to arrange the new hub. It usually happens within 14 days for both sets of benefits to be applied however as you need new equipment, there may be a slight delay on this time.
If you have any issues, or need any further help, pop back and let us know.
Thanks,
