Upgrades
All upgrades will be processed with effect from the 1st of the next month. For example if you request an upgrade on the 14th January, this would then be applied with effect from the 1st February.
Downgrades
Downgrades are also processed with effect from the 1st of the next month and can not be done retrospectively.
For example, as you are billed on the 1st of each month, you can not contact us on the 11th August to ask to be downgraded from the 1st August. Instead the downgrade would need to be processed with effect from the 1st September.
To request an upgrade/downgrade, please email our support team (support@onsim.uk).
For security reasons, please ensure the email is sent from the email address we currently hold for you, if this is not possible, we may need to request more information from you to verify your identity before we can implement this change for you.
