Compare data caps across major providers. Learn how much data you really need and which ISPs offer truly unlimited plans.
What Is an Internet Data Cap?
A data cap — also called a data limit, fair use policy, or data allowance — is the monthly limit on how much data you can use. If you exceed it, you may face overage charges (typically $10 per 50 GB) or have your speeds throttled.
Many providers now offer unlimited data plans with no caps at all. Here's a quick comparison of major providers:
| Provider | Connection Type | Monthly Data Cap | Overage Fee |
|---|---|---|---|
| Spectrum | Cable | Unlimited | None |
| AT&T Fiber | Fiber | Unlimited | None |
| Optimum | Cable, Fiber | Unlimited | None |
| Kinetic | DSL, Fiber | Unlimited | None |
| Xfinity | Cable | 1.2 TB (Unlimited option) | $10 per 50 GB |
| Cox | Cable | 1.25 TB | $10 per 50 GB |
| Mediacom | Cable | Up to 3 TB | $10 per 50 GB |
