I haven’t paid “full price” for a cellular phone plan for decades, but that doesn’t mean there haven’t been any trade-offs. Mobile Virtual Network Operators (MVNOs) buy network capacity in bulk from major carriers (MNOs like T-Mobile, Verizon, AT&T) and resell them to individual customers. For a while, the main trade-off for going with an MVNO (which buys bulk minutes and data from the major carriers) was slightly worse cellular coverage due to a lack of roaming agreements with other carriers. If you were on a AT&T MVNO, you could only use AT&T cell towers.
These days, the primary catch is data de-prioritization. To manage the demand, there are different Quality of Service Class Identifiers (QCI levels) that have different priorities on the network. In areas where there are a lot of people, especially things like concerts and sporting events, there is a lot of demand and those not at the front of the line will notice slow or no data.
This r/NoContract Reddit post provides an excellent collection of the data prioritization policies of the major carriers. It’s still a lot, so I have attempted to summarize everything below as much as possible.

For Verizon, QCI 8 is the highest priority level for consumers. Includes:
- All Verizon Postpaid “Traditional” plans (except “Welcome”).
- Visible+ and Visible+ Pro (owned by Verizon).
- Total Wireless’ Total 5G Unlimited and Total 5G+ Unlimited (owned by Verizon).
- Xfinity Mobile and Spectrum Mobile (owned by cable companies).
- US Mobile Unlimited Premium “Warp” (*for 5G w/ Premium Only)
QCI 9 is a step lower, the base tier. Includes:
- Verizon’s Unlimited Welcome plan (their most basic plan)
- Visible Base plan
- US Mobile Unlimited Starter “Warp” and other Warp plans.
- All other Verizon prepaid MVNOs.

For AT&T, QCI 7 is the highest priority level for consumers. Includes:
- Select AT&T Plans with special “Turbo” data.
QCI 8 is a step lower, but still considered higher priority. Includes:
- Select AT&T Plans with “Extra/Premium/Max” data.
- Cricket Supreme Unlimited, Cricket Sensible 10GB plans (*owned by AT&T)
- H2o, Consumer Cellular, and PureTalk MVNOs.
- US Mobile Unlimited Premium “Dark Star” (*Premium Only)
QCI 6 is another step lower, the base tier. Includes:
- AT&T base Unlimited plans for both AT&T postpaid and AT&T Prepaid.
- All other AT&T plans once the “Turbo/Premium” data is used up.
- Cricket Select Unlimited, Cricket Smart Unlimited plans (*owned by AT&T)
- US Mobile Unlimited Starter “Dark Star” and other Dark Star plans.
- All other AT&T prepaid MVNOs.

For T-Mobile, QCI 6 is the highest priority level for consumers. Includes:
- All T-Mobile Postpaid and Prepaid plans (except “Essentials”)
- Google Fi
QCI 7 is a step lower, the base tier. Includes:
- T-Mobile Essentials plans (their most basic plan)
- All other T-Mobile prepaid MVNOs, including Metro and Mint Mobile (both owned by T-Mobile).
Long-time readers will know that I was with Mint Mobile for a long time. I didn’t need much data back then. But each year, I felt the low priority of Mint Mobile data became more and more noticeable. Anywhere crowded, even an airport, and things would slow down significantly. Oftentimes, I basically had no data at all, which was very frustrating when just trying to call up an Uber. T-Mobile sells a lot of data to MVNOs, so perhaps that’s another reason. I first tried to jump ship to Visible, but they messed up my number port so badly that I couldn’t get 2FA verification codes for days so I quickly switched back to Mint Mobile.
Late last year, after a positive experience with US Mobile’s customer service involving their Apple Watch plans, I decided to switch to US Mobile’s Unlimited Premium plan which offers “Priority Data” on their Warp (Verizon) and Dark Star (AT&T) plans. They run a lot of promotions (often extending them over and over) but I jumped on the Warp plan with Unlimited Premium because it also included a free Apple Watch cellular plan. I’m paying a bit more than I used to with Mint Mobile, but I’ve definitely noticed the improvement in data quality. My number port was nearly instant. With their Unlimited Premium plan, I can even switch between networks for free if one place has better coverage, allowing me access to AT&T and T-Mobile towers.
I am happy with US Mobile as I now have high data speeds, multi-network coverage, reasonable cost, and decent customer service.
