There is no restriction on talk and text with any of the Mediacom Mobile plans. If you have the Unlimited plan and your data usage exceeds 20GB, then you’ll still have access to data but at reduced speeds. If you have the By the Gig plan, 1GB data will be automatically added after the consumption of the data limit. This will be done four times during the billing cycle. After that, you’ll still have access to data but at reduced speeds.
