This is guidance on how to read and understand the data. **Understanding Carrier Status Results** A carrier result is several fields from one carrier on the day it was checked. This is guidance on how to read and understand the data. **Summary**: A carrier status check tells you how one US carrier (Verizon, T-Mobile or AT&T) currently sees a device: whether it is barred, financed, under contract, or active on an account. A CLEAN carrier status is one answer from one carrier at one moment. It does not mean the device is unlocked, paid off on another carrier, or absent from the GSMA Blocklist. **One Check, Several Fields**: A carrier check returns more than one field, and each field answers a different question. The status field answers "is this IMEI blocked on the network right now?" The financial and insight fields answer "is there money or an account still attached to it?" Read them together, never the status field alone. | **Carrier** | **Field** | **What It Shows** | **Example Value** | | --- | --- | --- | --- | | Verizon | vzw\_status | Network status | LOST/STOLEN | | Verizon | financial\_status\_vzw | Financial obligations | UNPAID BILLS | | Verizon | device\_insight\_vzw | Device and account detail | DEVICE PAYMENT PLAN ACTIVE | | Verizon | activation\_status\_vzw | Active line status | NOT ACTIVE | | T-Mobile | tmo\_status | Network status | LOST/STOLEN | | T-Mobile | financial\_status\_tmo | Financial obligations | LOAN FINANCING | | AT&T | att\_status | Network status | LOST/STOLEN | | AT&T | financial\_status\_att | Financial obligations | UNPAID BILLS | | TracFone | tracfone\_status | Device status / brand / account status | USED / STRAIGHT TALK / VALID ACCOUNT |   The portal and CSV exports label the same data differently: FinancialStatusTMO is financial\_status\_tmo, DeviceStatusVZW is device\_insight\_vzw, and ActivationStatusVZW is activation\_status\_vzw. **CLEAN Plus Financing Is a Conditional Pass**: A CLEAN status with an open financing value is the most common combination customers ask about, and it is not a contradiction. CLEAN means the carrier is not blocking the IMEI today. A value such as LOAN FINANCING (T-Mobile) or DEVICE PAYMENT PLAN ACTIVE (Verizon) means an installment plan is still recorded as open. That is normal for a device partway through a 24 or 36 month plan. The risk is what happens next: if payments stop or the account closes with a balance, the carrier can block the IMEI for non-payment after you have bought or resold it. Treat CLEAN with open financing as a conditional pass, not a clear. **Unlocked Does Not Mean Paid Off**: SIM lock, financing and blocklist status are independent. A device can show Unlocked on its SIM lock, CLEAN on the GSMA Blocklist, and UNPAID BILLS on a carrier at the same time. The carrier that holds the plan is the one that can block the device. **What if the owner says the device is paid in full?** PrologMobile reports what the carrier's records show at the time of the check. If the owner has recently paid off the device, re-run the check before release to confirm the carrier's records have updated. **Carrier Flags Come Before the GSMA Blocklist**: A carrier marks a device lost, stolen or delinquent in its own systems first. The report reaches the GSMA Blocklist later, sometimes days or weeks later. During that window, a Blocklist-only screen shows CLEAN while the carrier check already shows the problem. If you screen trade-ins or purchases with the Blocklist alone, add the carrier checks. **Which Carriers to Check**: Check the carrier the device is locked to first. If the device is unlocked, check all three major US carriers; a device can be locked to one carrier and carry unpaid bills on another. For Apple, the OEM check returns the locked carrier and intended carriers, and the Automated carrier check uses them for you. For Android, the carrier field shows the original carrier of record, not the current carrier or the lock state, so check the original carrier first, then the other two. For dual-SIM devices, records can be filed against either IMEI, so check IMEI2 as well. **MVNOs and Prepaid Brands**: Most US prepaid and MVNO brands run on Verizon, AT&T or T-Mobile. Visible, Total Wireless, Straight Talk and Tracfone are Verizon brands; Cricket is AT&T; Metro and Mint are T-Mobile. For an MVNO device, read the host carrier's check. Lost or stolen blocks carry across networks, and financed devices stay locked until paid off, so they will not activate on an MVNO, even one on the same network. **A Result Has a Shelf Life**: A carrier result describes the device on the day it was checked. In PrologMobile data from June to August 2026, devices checked twice about a month apart showed 0.22% of clean Verizon statuses had become barred, and 0.26% of clean GSMA Blocklist results had become blocked. Keep the check date with every result, and re-run any carrier check older than a few weeks before you sell or ship a device. **Carrier Results in Cascading Call Flows**: A Cascading Call Flow (CCF) returns PASS or FAIL in cascade\_summary, with the reason for a failure, for example "Fail - VZW LOST/STOLEN". Which carrier and financing values return PASS or FAIL is customized to each customer's requirements. To review your flow, contact support@prologmobile.com. **How Often This Happens**: Carrier and financing issues are far more common than Blocklist hits. For every device the Blocklist catches, about 14 more pass it and fail somewhere else once financing flags are counted. Figures are from PrologMobile screening, aggregated across all customers. | **Measure** | **Jun to Aug 2026** | **Jun to Aug 2025** | | --- | --- | --- | | Devices on the GSMA Blocklist | 0.9% | 0.8% | | Verizon results with a financing or eligibility flag | 20.2% | 9.7% | | Blocklist-clean devices failing another check, including financing | 21.8% | 15.7% |   - [Frequently Asked Questions](https://info.prologmobile.com/frequently-asked-questions?hsLang=en) - [Getting started](https://info.prologmobile.com/getting-started?hsLang=en) - [Troubleshooting](https://info.prologmobile.com/troubleshooting?hsLang=en#main-content) - [Account Access](https://info.prologmobile.com/troubleshooting?hsLang=en#account-access) - [General](https://info.prologmobile.com/general?hsLang=en) prologmobile.com Help Center Copyright © 2026, PrologMobile
