There is no fixed amount of data a tablet uses per hour on a hotspot: it depends mainly on what you do, the quality you choose, and background activity. As a rough guide, AT&T lists video streaming at 240 MB per hour in SD and 900 MB per hour in HD, while its examples for video calls, gaming, and music are 480 MB, 60 MB, and 30 MB per hour. Treat these as estimates, not a guaranteed rate for every tablet or app.
Estimated tablet hotspot data use per hour
The hotspot is the connection; the tablet’s activity drives data use. These estimates come from different providers and settings, so they are useful comparisons, not results from a single standardized test.
| Activity or setting | Estimated data use | Source and qualification |
|---|---|---|
| SD video streaming | 240 MB per hour | AT&T, support page last updated March 9, 2026 |
| HD video streaming | 900 MB per hour | AT&T, support page last updated March 9, 2026 |
| Video calling, such as FaceTime or Zoom | 480 MB per hour | AT&T, support page last updated March 9, 2026 |
| Online gaming | 60 MB per hour | AT&T, support page last updated March 9, 2026 |
| Music streaming | 30 MB per hour | AT&T, support page last updated March 9, 2026 |
| Netflix Low | Up to 0.3 GB per hour | Netflix; publication year not stated |
| Netflix Medium | Up to 0.7 GB per hour | Netflix; publication year not stated |
| Netflix High, SD | Up to 1 GB per hour | Netflix; publication year not stated |
| Netflix High, HD | Up to 3 GB per hour | Netflix; publication year not stated |
| Netflix High, 4K | Up to 7 GB per hour | Netflix; publication year not stated |
| Disney+ highest-quality mobile setting cited as “Stream over Wi-Fi only” | Approximately 2.5 GB per hour | Disney+, page dated June 29, 2026; service-setting estimate, not a universal hotspot rate |
Why video quality changes the estimate
Video quality is a major variable: AT&T’s examples place HD streaming well above SD, and Netflix’s estimates rise to 3 GB per hour for HD and 7 GB per hour for 4K when High quality is selected. Apps may offer their own quality controls, and actual consumption can differ with the content, settings, and app behavior. Do not treat one service’s estimate as a prediction for every stream.

Estimate a session against your hotspot allowance
- Choose the activity and the closest published hourly estimate. Use the app’s quality setting when available.
- Multiply the hourly estimate by the time used. For example, two hours at AT&T’s HD estimate of 900 MB per hour is about 1.8 GB. That is arithmetic based on AT&T’s estimate, not a separate measurement.
- Compare the result with the hotspot data allowance shown for your own plan, then check actual recorded use in the tablet settings and carrier account.
Background activity, such as system or app updates, large downloads, and cloud syncing, can add substantial or less predictable usage to a session estimate.

Check and limit hotspot data use
Check device and carrier counters
On Galaxy devices, Samsung says users can check mobile and Wi-Fi data use, set data warnings and limits, and enable Data saver to restrict background data for selected apps. Available options can vary by carrier. See Samsung’s Galaxy connection and data-usage guidance. Device counters are useful estimates; check your carrier account for the usage recorded under your plan as well.
Plan rules differ. AT&T says each device connected or tethered to a mobile hotspot uses the plan’s data allowance. T-Mobile says hotspot availability and high-speed allowances vary by plan, and speeds may be reduced after the high-speed allowance is used. Check your carrier’s plan terms and usage counter rather than assuming these examples apply to every provider. See AT&T’s hotspot data-use instructions and T-Mobile’s hotspot plan guidance.
