Serving-Cell Log Parser
🔒 Runs in your browser
Paste a log above to see the serving cell.
Traces can contain subscriber identifiers (IMSI/IMEI). This runs in your browser — nothing is uploaded. Use the masker before sharing a trace.
For lawful, educational and professional-testing use. Provided as is, without warranty.
What `dumpsys telephony.registry` is
On any Android phone, adb shell dumpsys telephony.registry prints the current
radio state that the telephony framework holds: the registered network, the serving cell and
the last signal strength it reported. This tool reads that plain text and pulls out the
serving-cell fields into a clean card — the radio technology (RAT), the operator resolved from
the MCC/MNC, the tracking area (TAC), the cell and physical-cell identifiers (CID, PCI), the
channel number (EARFCN) mapped to its band and frequency, and the RSRP/RSRQ signal levels.
Text logs only — not binary drive-test files
The dumpsys output is documented, human-readable text, so it is safe to parse in the browser.
Proprietary binary drive-test captures — QXDM/.qmdl, TEMS, XCAL and similar — need
licensed dictionaries and are deliberately out of scope; paste one and the tool will say it
cannot recognise it. Parsing runs entirely in your browser and nothing is uploaded. Because a
radio log can carry an IMSI or location, mask it first if you plan to share it.
Frequently asked questions
What log does it read?
The text from `adb shell dumpsys telephony.registry`. It pulls out the serving cell fields — RAT, the MCC/MNC (resolved to an operator), TAC, the channel number (EARFCN, mapped to its band and frequency) and signal levels such as RSRP and RSRQ.
Does it read QXDM or TEMS logs?
No. Those are proprietary binary formats that need licensed dictionaries. This tool deliberately handles only the plain-text dumpsys output, which is documented and safe to parse in the browser.
Is it safe with real logs?
Yes — parsing runs entirely in your browser, nothing is uploaded. Because radio logs can contain IMSI and location data, mask them first with the IMSI/ICCID masker if you plan to share.
