What type of emails will drivers receive and how will this affect their mobile data usage?

There are two types of emails drivers may receive:

• An electronic weigh receipt (if the driver elects to receive them during registration)
• A service interruption message should CAT Scale encounter a system issue

Regarding mobile data, the data used by checking your favorite news website would be the same as weighing several times per month. So, you can expect a very low impact on data usage.
