Free IoT tools
Utilities our own team uses daily: decode the ICCID printed on a SIM, identify the operator behind an IMSI, validate an IMEI, or size a fleet's monthly data usage before choosing a plan. Everything runs in your browser — no identifier you paste is ever sent to a server.
Identifiers you paste never leave your browser
ICCID decoder
Validate the Luhn checksum and break down any SIM's ICCID: MII, country, issuer and account number.
Open toolMCC-MNC lookup & IMSI decoder
Identify country and operator from an IMSI or PLMN code, and search the full table of 3,000+ networks.
Open toolIMEI checker
Verify an IMEI's check digit, split TAC and serial number, and identify the reporting body.
Open toolMSISDN decoder
Normalize any number to E.164 format and split the country calling code from the national number.
Open toolIoT data usage calculator
Estimate monthly MB per device and per fleet from payload size, sending frequency and protocol (MQTT, HTTPS, CoAP…).
Open toolSignal quality interpreter
Convert CSQ to dBm and turn RSSI, RSRP, RSRQ and SINR into a clear signal-quality verdict.
Open toolAT commands
Cheat sheet of AT commands (CREG, CEREG, CSQ, CGDCONT…) with an AT+CGDCONT builder and a network-registration decoder.
Open toolAPN settings generator
Generate APN configuration for AT commands, ModemManager (nmcli) and the Android fields.
Open toolIoT battery life
Estimate months of life from the sleep current, active burst, cycles per day and battery capacity.
Open toolLTE bands & EARFCN
Convert between band, frequency and EARFCN, with the NB-IoT and LTE-M bands flagged.
Open tooleSIM activation code (LPA)
Parse and validate an eSIM activation code per GSMA SGP.22, with its QR.
