Improper use of unlocking software can render the phone permanently inoperable ("bricked").
Because iDEN technology relies on a highly specialized radio interface (MOTOtalk for direct communication and specific carrier towers for network calls), unlocking the CNS architecture will not allow the phone to work on modern GSM (T-Mobile, AT&T) or Verizon networks. Even with a modern SIM card inserted, an unlocked iDEN phone will find no active towers to broadcast or receive signals. Legitimate Uses for Old iDEN Handsets
By the late 2010s, the unique "chirp" network infrastructure was gone, turning these unlocked handsets into strictly offline collectibles. Conclusion: A Digital Artifact
The infrastructure that supported these phones no longer exists. Sprint (which acquired Nextel) officially shut down the iDEN network on June 30, 2013, and repurposed the spectrum. Unlocking an iDEN phone today will not allow it to work on modern 4G LTE or 5G networks, as the physical hardware lacks the necessary cellular bands.

Certain later Motorola iDEN models (like the i355, i576, or i680) feature a feature called "Direct Talk." This allows the phones to function as heavy-duty, off-grid, digital walkie-talkies completely independent of a cellular tower. This mode operates on the 900 MHz ISM band and works perfectly fine regardless of carrier locks. Conclusion
