If you scroll down to the FAQ section at the bottom of the Pricing page, it says:
Usage allowance is proportional to the number of credits that you purchase. For every 10,000 credits, you receive a set amount of the parameters detailed below.
Usage allowance
Entitlement per 10k operations licensed per month:
- Data transfer 5 GB
So, if you want more data transfer, simply purchase more credits either through your organisation’s subscription, or additional credits (one-time, or auto-purchasing).
Hope this helps! If you are still having trouble, please provide more details.
