Mobile Internet Speed Report: 4G vs 5G by Carrier 2026
By SpeedTestHQ Research · Updated April 28, 2026
Measured median mobile speeds by carrier — T-Mobile, Verizon, and AT&T — across 4G LTE and 5G. What you actually get versus what the ads claim.
US mobile internet speeds by carrier
T-Mobile leads US mobile speeds due to its mid-band 5G deployment on the 2.5 GHz spectrum (acquired from Sprint). Verizon's mmWave is faster in dense urban areas but covers a fraction of 1% of locations. AT&T trails in 5G speed but has comparable 4G coverage nationwide.
| Carrier | Network | Median DL | Median UL | Median Latency | Consistency Score |
|---|---|---|---|---|---|
| T-Mobile | 5G (mid-band dominant) | 185 Mbps | 22 Mbps | 28 ms | ★★★★★ |
| Verizon | 5G (C-Band + mmWave) | 210 Mbps | 28 Mbps | 20 ms | ★★★★☆ |
| AT&T | 5G (C-Band) | 155 Mbps | 18 Mbps | 25 ms | ★★★★☆ |
| T-Mobile | 4G LTE | 45 Mbps | 12 Mbps | 42 ms | ★★★★☆ |
| Verizon | 4G LTE | 38 Mbps | 10 Mbps | 38 ms | ★★★★☆ |
| AT&T | 4G LTE | 32 Mbps | 9 Mbps | 40 ms | ★★★☆☆ |
Median speeds from mobile speed tests (not WiFi) across urban, suburban, and rural environments. Consistency score reflects variability — how often you get near-median speeds vs outlier drops.
4G LTE vs 5G: when does 5G actually help?
- Streaming: 4G LTE (35–50 Mbps) is sufficient for 1080p streaming. 5G makes a practical difference only for 4K streaming on mobile, which few people do.
- Video calls: 4G LTE handles Zoom/Teams comfortably. 5G's lower latency (20–28 ms vs 38–45 ms on LTE) reduces audio sync issues in congested areas.
- Gaming: 5G's lower latency is meaningful for real-time mobile gaming. Mid-band 5G at 20–28 ms vs LTE at 38–45 ms is a 15–20 ms improvement — noticeable in competitive games.
- Crowded events: 5G's superior spectral efficiency (OFDMA) means you are less likely to see degraded speeds at concerts, stadiums, and airports.
Rural mobile internet speeds
In rural areas, most 5G is low-band (600–850 MHz), which delivers speeds only marginally faster than LTE: 60–80 Mbps vs 30–50 Mbps. For rural residents, home internet alternatives like Starlink or T-Mobile Home Internet often deliver better sustained throughput than mobile data.
Key findings
- T-Mobile leads on overall 5G speed and coverage: T-Mobile's mid-band 5G (n41/2.5 GHz) delivers a median 245 Mbps down with the broadest nationwide reach. Its consistency score of 82% is the highest of the three major carriers.
- Verizon mmWave is fastest but extremely limited: Where available, Verizon Ultra Wideband delivers 800–1,500 Mbps — the fastest mobile speeds measured. Coverage is limited to dense urban areas and select venues; most Verizon 5G users connect to mid-band at 120 Mbps median.
- Low-band 5G offers minimal improvement over LTE: AT&T and T-Mobile's 600–700 MHz 5G bands achieve 60–80 Mbps median — nearly identical to LTE. Users in areas served only by low-band see little practical benefit from a 5G-capable device.
- Mobile latency remains higher than wired: Even the best 5G connections average 20–28 ms — 2–4× higher than fiber at 5–8 ms. For latency-sensitive applications like competitive gaming, wired broadband remains preferable to mobile.
Methodology
Mobile speed data represents median SpeedTestHQ measurements from cellular connections (excluding Wi-Fi) on 5G-capable devices, segmented by carrier and reported network generation (5G NR vs LTE), over the 90-day period ending April 2026. Consistency score reflects the percentage of tests delivering at least 25 Mbps download. Rural figures are drawn from tests in census-designated rural areas with fewer than 2,500 residents. Carriers with fewer than 50,000 qualifying tests are excluded.
These figures are planning ranges, not a guarantee for every address or device. Your result can change with router placement, local interference, server distance, ISP routing, plan tier, firmware, client hardware, and time of day. For your own connection, run a speed test to see your current mobile performance.
Frequently Asked Questions
Which carrier has the fastest 5G?
Verizon's mmWave is fastest in select dense urban areas (1–3 Gbps), but T-Mobile has the fastest and most consistent 5G nationally due to its mid-band 2.5 GHz deployment. For most users, T-Mobile delivers the best everyday 5G experience.
Is 4G LTE fast enough for working from home?
4G LTE (30–50 Mbps download, 10–15 Mbps upload) is borderline for heavy WFH use — adequate for video calls and basic tasks, but insufficient for large file uploads or simultaneous calls. A fixed home internet connection (cable, fiber, or fixed wireless) is recommended for WFH.
How do I test my mobile internet speed?
Run a speed test on SpeedTestHQ with WiFi disabled — ensure you are on cellular only. Run 3 tests and record the median. Note whether your phone shows 4G or 5G in the status bar to determine which network you are actually on.
Why is my 5G speed lower than expected?
Most likely you are on low-band 5G (600–850 MHz), which offers only modest speed improvements over LTE. True 5G performance requires mid-band (1–6 GHz) or mmWave spectrum. Check your carrier's coverage map to see which 5G band your area receives.
