The MVNO Prepaid Trick: Buy a Flagship Phone for $400 Less

Some MVNOs sell flagship phones at deep discounts to attract customers. The trick: buy the phone, activate for one month, then cancel and use the unlocked phone on any carrier.

5 min readUpdated June 2026

How it works

Carriers like Boost Mobile, Cricket, and Metro by T-Mobile sometimes sell phones $200–400 below retail when you activate a new line. The phone is typically locked for a short period (often 60 days), but the total cost — discounted phone + 2 months of service — is still much cheaper than buying at full price or signing up for 36 months of bill credits.

Example: Galaxy S25 via Boost Mobile

Retail price (unlocked): $799

Boost activation price: $449

2 months of Boost service: $80

Total: $529 vs. $799 retail = $270 saved

After 60 days, request unlock and move to any carrier.

Step-by-step

1

Check which MVNOs currently have phone discounts (Boost, Cricket, Metro).

2

Buy the phone with a new activation. Use a new number (don't port your main number).

3

Pay for the required minimum service period (usually 1-2 months).

4

After the lock period, request a device unlock from the MVNO.

5

Once unlocked, insert your SIM from your preferred carrier.

Watch out for

  • Check the MVNO's unlock policy before buying. Some require 6+ months of service.
  • Make sure the phone supports the bands for your target carrier.
  • This works best with a spare number. Don't port your primary number for a short-term trick.
