The short version
T-Mobile is faster and cheaper when you have 5G coverage. Starlink works everywhere you can see the sky. For RV owners, the question isn't which is "better" — it's where you travel.
If you mostly stay at RV parks near cities and towns, T-Mobile wins on price and speed. If you boondock, visit national parks, or travel through the rural West, Starlink is the only option that reliably works.
Most serious full-timers end up running both.
Head-to-head comparison

| Equipment cost | $299-599 (dish) | $50-300 (gateway) |
| Download speed | 50-200 Mbps | 50-300 Mbps |
| Upload speed | 10-20 Mbps | 10-50 Mbps |
| Latency | 25-60 ms | 15-35 ms |
| Works while driving | Yes (with actuated dish) | Yes |
| Rural coverage | Everywhere with sky view | 5G/LTE towers only |
| Power draw | 75-100W (Gen 3), 25-40W (Mini) | 10-15W |

Where T-Mobile wins
Price. T-Mobile AWAY starts at $50/month. Starlink Mobile Regional is $150/month. Over a year, that's $1,200 in savings.
Speed in coverage areas. When you have a strong 5G signal, T-Mobile often outperforms Starlink. We've seen 200-300 Mbps at well-covered RV parks, compared to Starlink's typical 50-150 Mbps.
Latency. T-Mobile's 15-35ms latency is better for video calls and gaming than Starlink's 25-60ms. If you work remotely and spend all day on Zoom, you'll notice the difference.
Power consumption. The T-Mobile gateway draws 10-15W versus Starlink Gen 3's 75-100W. For boondockers counting watts, this matters. Though Starlink Mini at 25-40W narrows the gap.
Setup. Power on the T-Mobile gateway. Done. No dish positioning, no obstruction checks, no mounting.
Where Starlink wins
Coverage is everywhere. This is the whole reason Starlink exists. National forests, BLM land, remote beaches, mountain passes — anywhere you can see a patch of sky, Starlink works. T-Mobile has zero coverage in most of these places.
Consistency. Starlink delivers 50-100 Mbps whether you're in a Walmart parking lot or a dispersed campsite in Montana. T-Mobile's speeds swing wildly based on tower distance, congestion, and terrain.
No address restrictions. T-Mobile Home Internet is locked to a specific address. T-Mobile AWAY works on the road but is a separate product with different terms. Starlink's Mobile Regional plan works anywhere in the US with zero address games.
In-motion use. With the Starlink actuated dish ($2,500), you get internet while driving. T-Mobile also works in motion, but drops out frequently between towers on highways through rural areas.
The real question: where do you camp?
Mostly RV parks near towns? → T-Mobile AWAY. Save $100/month and get faster speeds.
Mix of RV parks and boondocking? → Starlink Mobile Regional. The rural coverage is worth the premium.
Full-time, everywhere? → Both. Use T-Mobile as primary when you have signal, Starlink as fallback. A travel router like the GL.iNet Slate AX with dual WAN can automatically fail over between the two.
Work remotely and can't afford drops? → Both, no question. One will always be up when the other isn't.
Cost comparison over 12 months
| Setup | Year 1 total | Monthly average |
|---|---|---|
| T-Mobile AWAY only | $900-1,500 | $75-125 |
| Starlink only (Mini) | $2,099 ($299 dish + $1,800/yr) | $175 |
| Starlink only (Gen 3) | $2,399 ($599 dish + $1,800/yr) | $200 |
| Both (T-Mobile + Starlink Mini) | $2,999-$3,099 | $250-258 |
Equipment you need
For Starlink
- Starlink dish ($299 Mini or $599 Gen 3)
- No-drill RV mount — ladder clamp or hitch mount
- Mobile Regional plan ($150/month)
For T-Mobile
- T-Mobile 5G Gateway ($50-300 depending on plan)
- T-Mobile AWAY plan ($50-100/month)
- External antenna ($30-50) if you want to boost weak signals
For both (dual WAN setup)
- GL.iNet Slate AX travel router — connects to both and auto-switches ($70-90)
- Cat6 ethernet cables for wired connections to each device
- Surge protector — protect both devices from campground power spikes
Common mistakes
Buying T-Mobile Home Internet for your RV. Home Internet is address-locked. It will stop working when you leave your registered address. You need T-Mobile AWAY specifically.
Assuming Starlink works in dense tree cover. Starlink needs a clear view of the sky. A campsite surrounded by tall pines will have constant dropouts. Check obstructions with the Starlink app before committing to a spot.
Not testing T-Mobile coverage on your actual routes. Coverage maps show theoretical coverage. Real-world coverage in mountain valleys, canyons, and remote highways is often much worse. Drive your planned routes with a T-Mobile phone first.
Oversizing your Starlink dish. If you don't need in-motion internet, the Starlink Mini ($299) is plenty for most RV setups and draws a third of the power of the Gen 3.
Our recommendation
Start with whichever matches your travel style. If you mostly stay in developed areas, try T-Mobile AWAY first — it's the cheaper experiment. If you go off-grid regularly, start with Starlink.
After 2-3 months of travel, you'll know whether you need the second service. Most full-timers who work remotely end up adding the other one within their first season.
