I’m Han Lijie (@HANLIJIE
), founder of HKCARD ELECTRONICS CO.,LIMITED in Hong Kong. From our ISO 9001 Shenzhen factory, we ship 5 million blank SIM cards monthly — and Australia is now our #1 NB-IoT market. If you’re a Sydney, Melbourne, or Brisbane developer building smart meters, trackers, or sensors, this is your complete NB-IoT SIM programming tutorial using HKCARD’s 100% empty SIM cards.

“HKCARD’s NB-IoT blank SIMs passed Telstra Cat-M1 field trials in 48 hours.” – IoT Startup, Brisbane
Step-by-Step: Program NB-IoT SIM in <15 Minutes (Australia Fast Track)Tools You Need (Free with 1K+ Order)
  • Quectel BG96 / BC68 module (or any NB-IoT dev board)
  • ACR122U-NFC USB reader (for initial programming)
  • AT Command Tester + PySIM (Linux/Mac)
  • HKCARD NB-IoT blank SIM (MOQ 100)
Step 1: Initialize Blank SIM (USB Reader)
bash
 
# Detect card
pcsc_scan

# Select ADF_USIM (HKCARD default)
echo "00 A4 04 00 07 A0 00 00 00 87 10 02" | xxd -r -p | pcsc_send

# Auth ADM (HKCARD factory key)
echo "00 20 00 80 08 48 4B 43 41 52 44 00 00" | xxd -r -p | pcsc_send
Step 2: Write NB-IoT Core Files
bash
 
# 1. IMSI (use 90114… for Telstra/Optus test)
echo "00 F2 6F07 00 09 89 01 14 00 00 12 34 56 F7" | xxd -r -p | pcsc_send

# 2. KI (16-byte)
echo "00 F2 6F20 01 10 00112233445566778899AABBCCDDEEFF" | xxd -r -p | pcsc_send

# 3. OPc (optional for Telstra)
echo "00 F2 6F22 01 10 63BF...[32 hex]" | xxd -r -p | pcsc_send
Step 3: Configure NB-IoT Parameters (EF Files)
bash
 
# EF_NBIoT_APN (custom APN: iot.telstra)
echo "00 D6 6F4C 00 0C 69 6F 74 2E 74 65 6C 73 74 72 61" | xxd -r -p | pcsc_send

# EF_PSM_eDRX (PSM: 1hr, eDRX: 81.92s)
echo "00 D6 6F4D 00 04 0A 08 51 00" | xxd -r -p | pcsc_send
Step 4: Insert into Module & Test AT Commands
bash
 
AT+CFUN=0
AT+CPIN?
AT+CGDCONT=1,"IP","iot.telstra"
AT+QNBIOTRAI=1,1   # Enable RAI for low power
AT+CFUN=1
AT+CEREG?          # Should return +CEREG: 0,1 (registered)
Result: Your NB-IoT SIM is live — sending data in PSM mode.
