Does Starlink Have a Data Cap? Data Limits and Usage Explained (2026)
Short answer
Most Starlink plans have no hard data cap. The exception is Roam 100GB, which slows to under 1 Mbps after 100GB until your next billing cycle; Roam 300GB has a 300GB high-speed allowance. Residential and Roam Unlimited are unlimited, though Starlink can slow traffic at busy times, and in September 2026 some extreme users (several terabytes a month) reported 10 Mbps speed limits.
Key takeaways
- Residential plans and Roam Unlimited: unlimited data, subject to Starlink’s fair-use policy.
- Roam 100GB: under 1 Mbps after 100GB; you can no longer buy extra high-speed data on that plan.
- Very heavy users (around 5TB+ a month) on consumer plans have reported temporary 10 Mbps limits.
- A one-hour HD video call uses roughly 1–1.5GB; an HD movie about 3GB.
- Star Surf rental kits come set up with unlimited data as standard.
Does Starlink have a data cap?
Mostly no. Starlink advertises unlimited data on its Residential and Roam Unlimited plans. What it does have is network management: in congested areas some plans are deprioritized at peak times, and the terms prohibit business or enterprise use on consumer plans.
What are the data limits on each Starlink plan?
| Plan (US, Oct 2026) | Data | After the limit |
|---|---|---|
| Residential 100 / 200 / Max | Unlimited | No cap; fair-use rules apply |
| Roam 100GB ($55) | 100GB high speed | Under 1 Mbps until next cycle |
| Roam 300GB ($80) | 300GB high speed | Reduced speed; check plan terms |
| Roam Unlimited ($175) | Unlimited | No cap; fair-use rules apply |
In January 2026 Starlink replaced Roam 50GB with Roam 100GB, added unlimited low-speed data after the allowance and removed the option to buy extra high-speed data on that plan.
Is ‘unlimited’ really unlimited?
For normal households and travelers, yes. In September 2026, ISPreview reported that some users who regularly passed about 5TB a month, mostly in the US and Mexico, had speeds limited to around 10 Mbps for the rest of the billing cycle, with Starlink citing business use on a consumer plan. Starlink hasn’t published a threshold, and some users had the restriction reversed.
How much data will I actually use?
Rough figures help you choose a plan or decide whether a rental is enough:
| Activity | Approx. data | Per |
|---|---|---|
| HD video call (Zoom/Teams) | 1–1.5GB | Hour |
| HD streaming | About 3GB | Hour |
| 4K streaming | About 7GB | Hour |
| Card reader / POS | Under 0.1GB | Day |
| 1080p livestream upload | 2–4GB | Hour |
A remote worker with four hours of calls a day can use 100GB in under three weeks. A wedding livestream plus guest Wi-Fi can use 20–50GB in a day. Our event bandwidth guide covers bigger events.
Our recommendation
Don’t want to worry about data at all? Star Surf kits come pre-configured with unlimited data as standard, so a camping trip, an event or a few weeks of remote work won’t run into a 100GB slowdown.
Reserve a Starlink kitAsk us a questionHow can I cut Starlink data use?
Lower video quality in streaming apps, turn off auto-updates and cloud photo backups while on a capped plan, and use the Starlink app’s usage view to watch totals. For events, put card readers and staff on their own network and limit guest streaming.
FAQs
What happens when I hit the Roam 100GB limit?
Your service continues at under 1 Mbps until the next billing cycle. That’s enough for messages and email, not video.
Does Starlink throttle unlimited plans?
Starlink can deprioritize traffic during congestion, and very heavy users on consumer plans have reported temporary speed limits.
How do I check my Starlink data usage?
Open the Starlink app or your account page and look at the usage section for the current billing cycle.
Is 100GB enough for a month?
For light browsing and occasional streaming, yes. Daily video calls or streaming will use it up in a few weeks.
Do rental kits have data limits?
Star Surf kits come set up with unlimited data as standard.
Need Starlink for a few days or a few weeks?
Rent from $20/day. Pick up in American Fork, UT, or have it shipped anywhere in the US in a protective hard case.
