For example:
You currently have a $99 shareable Business Mobile Plan with a 12GB monthly data allowance and Extra Data (an Eligible Service) and a non-shareable $45 My Business Wireless Broadband Plan 20GB with Extra Data (not an Eligible Service). You then buy a Medium Business Mobile Plan for $60 and a 60GB included monthly data allowance.
Your Business Mobile Plan is automatically converted to No Excess Data Charges, giving your account a Shared Monthly Data Allowance of 72GB across both your Business Mobile Plan and Business Mobile Data Plan. If you exceed the Shared Monthly Data in a month, then both services will have speeds shaped to a maximum of 1.5Mbps but no excess data charges will apply.
Your Business Mobile Plan continues unchanged with the same minimum monthly charge and any existing bonus data or credit, except that Extra Data will be removed. However, Extra Data will remain on your non-shareable $45 My Business Wireless Broadband Plan, which continues unchanged.
