MVNO vs Big Three Carrier: What You Actually Give Up

Who runs on which network

What you give up

• Data priority: when a tower is busy, MVNO data is usually slowed before the big carrier's own customers. Most of the time you won't notice; at stadiums and rush hour you might.
• Hotspot speed: often capped at 3 to 15 Mbps.
• Phone deals: few MVNOs offer big trade-in credits.
• Family discounts: the per-line price usually stays the same as you add lines.
• Stores: many MVNOs are online only. Metro, Cricket and Straight Talk at Walmart are exceptions.
• Roaming: some MVNOs don't include the roaming partners big carriers use in rural areas. Check the MVNO's own coverage map.
• International data and perks like Netflix or Hulu.

What you don't give up

• The towers: you use the same network.
• 5G: most MVNOs include 5G, and several include Ultra Wideband (Total Wireless MAX 5G, Straight Talk Gold).
• Your number and your phone: you can bring both.
• Satisfaction: customers rate several smaller carriers above the big three (see the survey).

Price difference for one line

Paying a little more for priority

Several MVNOs sell premium tiers that fix the main drawback. Visible+ ($35) and Total Wireless MAX 5G BYO ($25) include premium data on Verizon's network. Metro Unlimited Premium ($55) and Mint Unlimited (50GB premium) do the same on T-Mobile's. These still cost much less than the big carriers' plans.

When to stay with a big carrier

• You have 4 or more lines and the family price is close.
• You want the newest phone with trade-in credits.
• You travel abroad often and want data included.
• You want help in person.

What deprioritization feels like

Most of the day, an MVNO line runs at the same speed as the big carrier's. When a tower is crowded, such as at a stadium, a concert or a busy train station, MVNO data is slowed first. Pages load slower and video drops in quality. If you're often in crowded places and rely on data there, pay a few dollars more for a plan with premium data.

Support

Big carriers have stores and phone support. Most MVNOs are online only, with chat. Metro, Cricket and Straight Talk (through Walmart) are the main exceptions. Customer ratings don't seem to suffer: smaller carriers often score higher in satisfaction surveys.

Switching from a big carrier to an MVNO

1. Check your phone works on an MVNO's network and is unlocked (is my phone unlocked?).
2. If you're paying off a phone, the remaining balance becomes due when you leave. Pay it off or plan for it (hidden costs of switching).
3. Get your account number and number transfer PIN from a big carrier. Don't cancel a big carrier yourself: the move cancels it.
4. Sign up with an MVNO and choose to keep your number. Most newer phones can use an eSIM, so you're often live within minutes (how to switch to eSIM).
5. Pick the MVNO on the network that already works for you. If you're on Verizon now, Visible or Total Wireless keeps the same coverage; on T-Mobile, Mint or Metro does.

The bottom line

For most single users and couples, an MVNO gives you the same coverage for about half the price. The real trade-off is slower data when a tower is busy. If that matters, a premium MVNO tier costs $5 to $20 more and still saves money. Related: prepaid vs postpaid.
