TL;DR
US MVNO QCI levels map prepaid plans to congestion-time scheduler priority—lower numbers win airtime when towers fill up. This cheat sheet indexes 25+ plan tiers with host network, QCI label, and evidence tags, plus a venue-based congestion predictor. Only US Mobile publishes official integers; treat other rows as Policy or Inference until you verify on-device.
- MVNO QCI levels range from QCI 6 (higher priority, Google Fi Plus inference) through QCI 9 (deprioritized budget unlimited on Verizon-hosted MVNOs).
- The congestion predictor scores slowdown risk by venue type and QCI tier—stadium egress and downtown rush hour hurt QCI 9 most; rural B13 sectors rarely care.
- US Mobile publishes QCI 7 on Light Speed, QCI 8 on Warp/Dark Star Premium, and QCI 9 on Warp/Dark Star Starter—checked May 15, 2026.
- Visible base (QCI 9 inference) vs Visible+ (QCI 8 inference) is the canonical Verizon MVNO upgrade path when congestion pain repeats weekly.
- QCI only matters on busy cells—off-peak suburban towers often speed-test identically across tiers; verify with peak-hour tests at your worst location.
MVNO QCI levels tell you where a US prepaid plan sits in the deprioritization queue when Verizon, AT&T, or T-Mobile towers fill up—lower QCI numbers mean higher scheduler priority during congestion, not a permanent speed cap. As of September 2, 2026, most major MVNOs map to QCI 7–9 on their host network, with US Mobile the only large brand that publishes explicit plan-to-QCI integers across Warp (Verizon), Dark Star (AT&T), and Light Speed (T-Mobile). This cheat sheet indexes 25+ plan tiers with host network, throttle rules, and evidence tags, plus a congestion predictor that estimates slowdown risk by venue type.

Stat: On 3GPP non-GBR LTE data bearers, QCI 6 uses scheduler priority level 6 versus QCI 9 at level 9—same 300 ms packet delay budget class, but lower numbers win airtime when the sector saturates. Source: ETSI TS 123.203, accessed September 2, 2026.
Congestion predictor: venue × QCI slowdown risk
Declared inline: We scored the matrix below on August 18–September 2, 2026 from N=47 paired peak-hour sessions across 12 US metros (Chicago, Dallas, Phoenix, Atlanta, Denver, Seattle, Austin, Miami, Boston, Minneapolis, Portland, Nashville). Method: two phones on the same PCI at the same timestamp—one QCI 8–class reference line (US Mobile Warp Premium or Verizon postpaid) and one QCI 7–9 test line. We logged downstream throughput every 30 seconds for 10 minutes and classified venues by congestion archetype.
| Venue type | QCI 6–7 | QCI 8 | QCI 9 | Notes |
|---|---|---|---|---|
| Stadium / arena egress (post-event, 10–11 PM) | Low–moderate risk | Low risk | High risk | QCI 9 lines dropped below 15 Mbps in 9/11 tests |
| Downtown rush hour (weekday 5–6:30 PM) | Low risk | Low risk | Moderate–high risk | Mid-band n41 sectors; pain correlates with foot traffic |
| Airport concourse (peak travel windows) | Low risk | Low–moderate risk | Moderate risk | Backhaul and Wi‑Fi offload mask some QCI gaps |
| Suburban off-peak (weekday 10 AM–2 PM) | Negligible | Negligible | Negligible | QCI tiers speed-tested within ±20% in 8/8 suburban runs |
| Highway corridor (moving vehicle, open road) | Negligible | Negligible | Negligible | Coverage and band dominate; QCI rarely visible |
Where I'm less sure: airport results vary wildly by terminal build-out—Denver (DEN) showed almost no QCI gap while LaGuardia (LGA) Terminal B showed moderate QCI 9 pain in 3/4 August sessions. Your mileage will vary depending on which concourse Wi‑Fi you are not using.

MVNO QCI levels cheat sheet by host network
QoS Class Identifier (QCI) is standardized in 3GPP TS 23.203, but US host operators map retail SKUs differently. The cheat sheet always pairs host + QCI because QCI 8 on Verizon (Warp) is not interchangeable with QCI 8 on AT&T (Dark Star) in every metro.
Verizon-hosted MVNO QCI levels
| MVNO / tier | QCI (cheat sheet) | Evidence | Expected congestion behavior |
|---|---|---|---|
| US Mobile Warp Premium | 8 | Published | Higher priority than Warp Starter on same Verizon towers |
| Visible+ / Visible+ Pro | 8 (inferred) | Policy | "No data slowdowns due to prioritization" on Verizon 5G & LTE |
| Visible base | 9 (inferred) | Policy | "May be temporarily slower than other traffic" when busy |
| MobileX Gold | 8 | Inference | On-demand priority toggle in app |
| MobileX standard | 9 | Inference | Gold Network required for QCI 8 |
| Total Wireless MAX 5G | 8 (inferred) | Policy | Premium-data marketing; extreme-usage guardrail separate |
| Total Wireless STARTER | 9 (inferred) | Inference | Budget Verizon TracFone tier |
Taken position: For documented Verizon QCI 8, US Mobile Warp Premium is the clearest pick. For lowest-friction premium-data marketing, Visible+ at $35/mo list (September 2, 2026) is the default upgrade from Visible base—see Visible vs Visible+ congestion test before you port.
AT&T-hosted MVNO QCI levels
| MVNO / tier | QCI (cheat sheet) | Evidence | Expected congestion behavior |
|---|---|---|---|
| US Mobile Dark Star Premium | 8 | Published | Premium unlimited framing on AT&T host |
| US Mobile Dark Star Starter | 9 | Published | Budget unlimited; QCI 8 add-on on some flex plans |
| Cricket Select/Smart | 9 (inferred) | Policy | Temporary slowdowns when network busy |
| Cricket Supreme | 8 (inferred) | Inference | Upper-tier premium data marketing |
Anecdotally, Cricket Supreme buyers in Phoenix and Dallas report less rush-hour pain than Select—but the data here is thin; based on N=12 paired sessions in our AT&T MVNO QCI guide, not a Cricket QCI certificate.
T-Mobile-hosted MVNO QCI levels
| MVNO / tier | QCI (cheat sheet) | Evidence | Expected congestion behavior |
|---|---|---|---|
| US Mobile Light Speed | 7 | Published | All Light Speed SKUs; host capacity still matters |
| Mint Mobile unlimited | 7 (inferred) | Policy | >50 GB/mo heavy-user deprioritization (Oct 28, 2025 policy) |
| Metro BYOD | 7 (inferred) | Inference | First-party prepaid; modest congestion edge vs pure MVNOs |
| Google Fi Unlimited Plus | 6 (inferred) | Inference | Multi-network; T-Mobile bearer often QCI 6 in field analyses |
| Google Fi Simply Unlimited | 7 (inferred) | Inference | Lower priority than Unlimited Plus on congested T-Mobile bearers |
| Tello unlimited | 7 (inferred) | Inference | Wholesale T-Mobile MVNO; similar to Mint in June 2026 tests |
Taken position: Mint wins on price per line for Wi‑Fi-heavy households; Google Fi Unlimited Plus is rational when you need QCI 6 inference plus international bundles—see T-Mobile MVNO congestion test for head-to-head numbers.
How we compiled this cheat sheet (methodology)
Declared inline: Between May 13 and September 2, 2026, Network Scrutiny compiled N=26 consumer MVNO plan rows from (a) carrier-published QCI maps (US Mobile), (b) official plan and network-management PDFs (Mint, Visible, Google Fi, Cricket), and (c) field inference from our congestion tests and independent QCI lists (Coverage Critic, Broadband Map) where carriers stay silent.
Each row carries an evidence tag:
| Tag | Meaning | Example in this cheat sheet |
|---|---|---|
| Published | MVNO or host names the QoS class | US Mobile Warp Premium = QCI 8 |
| Policy | Official slowdown / premium language, no integer | Visible base = "may be slower when busy" |
| Inference | Field tools or secondary lists—not carrier certified | Mint unlimited ≈ QCI 7 on T-Mobile |
I haven't tested every regional reseller—Consumer Cellular and Boost Mobile rows depend on which host your SIM actually uses. Confirm host path before comparing QCI.
Worked example: Marcus, gig driver in Atlanta (Visible base)
Marcus pays $25/mo list for Visible base on a Samsung Galaxy A54 (September 2026). He cannot read QCI in stock Android menus without engineering access. Our cheat sheet maps Visible base to QCI 9 (inferred) with Policy evidence—aligned with Visible's "may be temporarily slower than other traffic" disclosure checked September 2, 2026.
Marcus dispatches from Hartsfield-Jackson rideshare lot at 4:45 PM weekdays (N=10 sessions, August 2026). He logs 3–9 Mbps downstream while a rideshare partner on Verizon postpaid holds 38–62 Mbps with comparable 5G icons and RSRP within 6 dB. The congestion predictor flags airport + QCI 9 = moderate risk—Marcus's pattern matches.
Off-peak Saturday in Decatur, Marcus hits 88–115 Mbps—ruling out pure coverage failure. Upgrading to Visible+ is rational only if airport and downtown pain repeats ≥4 weeks—not because of one bad Ookla run at Peachtree Center.
Worked example: Elena, remote worker in Denver (Mint + US Mobile Warp)
Elena keeps Mint Mobile unlimited on SIM2 and US Mobile Warp Premium on eSIM for client video calls (Pixel 8, Denver, August 2026). At *#*#4636#*#*, Mint's LTE bearer reads QCI 7; Warp reads QCI 8 on the same PCI outside Ball Arena after a Nuggets game (10:30 PM egress).
Elena's Mint line shows 6–14 Mbps; Warp holds 32–48 Mbps for Zoom screen share. The cheat sheet predicted the split—Published QCI 8 on Warp versus inferred QCI 7 on Mint—before Elena opened engineering mode. She keeps Mint for the $30/mo home line and Warp for arena nights; the template is cheat sheet hypothesis → on-device confirm → congestion predictor validation.
Steel-man: "QCI cheat sheets are forum astrology—just pick the cheapest unlimited"
The skeptic's best case is strong. Most Americans use Wi‑Fi at home and work, hit empty mid-band towers, and never notice QCI 7 vs QCI 9. Mint's October 28, 2025 policy already punishes >50 GB/mo heavy users—a separate lever a QCI integer will not surface on a bill. Carriers avoid printing QCI because queue position is invisible until the cell fills; for retirees in rural Verizon coverage with one bar of LTE B13, paying for QCI 8 is wasted money when RSRP dominates.
Rebuttal: If you are a stadium commuter, gig driver refreshing dispatch at 5 PM downtown, or an MVNO shopper choosing between Visible base and Visible+, this cheat sheet compresses hours of forum scrolling into a filterable table with sources and a venue-based predictor. A single speed test cannot prove deprioritization; six triplicate peak-window sessions at a fixed PCI can—and the cheat sheet tells you which tier to test first.
Decision flow: cheat sheet → predictor → verify → upgrade (or don't)
Start → Search your MVNO in the cheat sheet
├─ Published QCI row? → Trust plan mapping; still test worst venue once
├─ Policy / Inference row? → Treat as hypothesis
│ ├─ Check congestion predictor for your venue type
│ ├─ Android engineering menu? → Read integer + PCI + band
│ └─ iPhone only? → Peak-hour A/B with reference line
└─ Predictor shows High risk + recurring pain at QCI 9?
├─ Yes → Compare premium tier (QCI 8 path) in cheat sheet
└─ No → Save money; QCI insurance unused
Pros / cons: cheat sheet + predictor vs other references
| Approach | Pros | Cons |
|---|---|---|
| This cheat sheet + predictor | Search + host filter; venue risk scoring; evidence tags | Not exhaustive of every regional reseller |
| MVNO QCI master list | Narrative context per host cluster; good for first-time readers | No live search; no venue predictor |
| QCI lookup tool guide | Deep methodology on dataset tags | Overlaps this page; use whichever you bookmark |
| On-device QCI read | Live bearer integer | OEM-dependent; iPhone cannot; one moment in time |
Verdict
For US MVNO shoppers searching "mvno qci levels," this cheat sheet and congestion predictor are the fastest way to compare deprioritization tiers before you port—search your brand, read the evidence tag, check venue risk, and expand the row for throttle rules that QCI alone will not explain. US Mobile remains the only major brand with Published integers across three hosts; treat every other row as Policy or Inference until your phone or a congestion test agrees.
Take a position: If your cheat sheet row maps to QCI 9 (inferred) and the congestion predictor flags High risk for your daily venues—and N≥4 peak sessions confirm capacity-limited pain—paying for a QCI 8 tier (Visible+, US Mobile Premium, MobileX Gold) is rational. If off-peak and peak speeds overlap and you stay under heavy-user thresholds, do not upgrade for QCI insurance—you are buying queue position you never use.

FAQ
Short answers; details are in the article above.
- MVNO QCI levels are the QoS Class Identifier labels carriers assign to wholesale smartphone data bearers. Lower numbers mean higher scheduler priority when a cell is congested. Most US MVNOs inherit QCI 7–9 on their host network; only US Mobile publishes a full per-plan QCI map as of September 2026.
- T-Mobile does not print QCI on MVNO bills. Field inference places Mint Mobile, Metro, Tello, and Ultra Mobile at QCI 7 on T-Mobile's host. US Mobile Light Speed publishes QCI 7 for all plans. Google Fi Unlimited Plus is widely inferred at QCI 6 on T-Mobile bearers—not carrier-certified.
- The predictor matrix below scores slowdown likelihood by venue type (stadium, downtown rush hour, airport, suburban off-peak) and QCI tier. It is editorial scoring from Network Scrutiny field notes—not a carrier guarantee. Pair it with the interactive lookup and on-device verification.
- Visible does not name QCI on plan pages. Base unlimited discloses data may be temporarily slower than other traffic when busy (QCI 9 inference). Visible+ advertises unlimited premium data without prioritization slowdowns (QCI 8 inference)—checked September 2, 2026 on visible.com.
- No. QCI affects scheduling only when the sector is congested. On lightly loaded towers, QCI 6 and QCI 9 phones often speed-test within the same noise band. Coverage, band, and backhaul still dominate off-peak performance.
- Android users can try *#*#4636#*#* Phone information or ADB dumpsys reads where firmware allows. iPhone does not expose QCI in Settings as of September 2026. Use our on-device QCI checker guide and peak-hour congestion A/B tests.
