About this Montblanc × Sprint unlock

Sprint locks devices to its network when sold on contract or financed. Unlocking your Montblanc is straightforward once your account meets Sprint's eligibility criteria — typically the device must be paid off and not reported lost or stolen.

DeviceDecoded uses the manufacturer's official unlock channel. We submit your Montblanc's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.

FAQ — Montblanc on Sprint

Can Sprint block this unlock?
No. Once your Montblanc's IMEI is whitelisted on the manufacturer's database, Sprint cannot reverse it.
Will my Montblanc stay unlocked after a factory reset?
Yes. The unlock is permanent at the factory level — it persists through factory resets, OS updates, and SIM changes.
Do I need my Sprint account credentials?
No. We unlock by IMEI alone. You don't need to provide your Sprint username, PIN, or account number.
What if my Montblanc is still on a Sprint payment plan?
It depends on the device's status. Start with the eligibility check at our unlock checkout — that page explains how the two-stage payment works before you commit.
