About this Kexin Tone, Maxin Tone, I-Guarder × Sprint unlock

About Sprint unlocks (post-merger)

Sprint completed its merger with T-Mobile in 2020 and the Sprint network has since been fully integrated into T-Mobile's. Sprint-branded devices are now serviced under T-Mobile's unlock framework, though Sprint-locked devices retain their original Sprint lock code structure and historically had different eligibility windows than T-Mobile postpaid devices.

Eligibility (typical)

Per the published policy, Sprint-locked devices are generally eligible to unlock once the account is in good standing, the device is paid off (no remaining Sprint Flex / installment balance), the device has been active on the network for the minimum policy window, and the device has not been reported lost or stolen. Domestic SIM unlock and international unlock are handled the same way through the manufacturer channel.

What DeviceDecoded does

We submit your Sprint IMEI through the manufacturer's official unlock channel — not through Sprint or T-Mobile's customer-service request flow. The unlock is permanent at the factory level, persists through factory resets, OS updates, and SIM swaps, and works for any compatible carrier worldwide.

Sprint-specific notes

  • Older CDMA-only Sprint devices — some legacy handsets only support Sprint's old CDMA radio and cannot be used on a GSM SIM regardless of unlock status; the eligibility check identifies these.
  • Boost Mobile and Virgin Mobile — these are separate sub-brands; Boost devices follow Boost's own unlock pathway.
  • Lease vs. purchase — Sprint Lease and Sprint Forward devices had different unlock terms than purchased phones; the eligibility check distinguishes.

Sprint country coverage

Sprint operates in 3 countries. Your Kexin Tone, Maxin Tone, I-Guarder unlock works regardless of which country it was originally sold in.
