MC-i4: Adding a Topcon SIM card – SIM installation and configuration (Part 1 of 2)

The following steps apply to the MC-i4:

  • Remove the eight (8) retaining screws from the base of the MC-i4.
  • Remove the base.

Note: When working with multiple MC-i4s at one time, be careful not to mix bases as the unit's serial number and other important information is marked on the label affixed to the base.

  • Insert the SIM card into the SIM card slot.
  • Reinstall the base and the eight (8) retaining screws using Blue Loctite and torque to 12 in-lbs.

Note: Failure to tighten all screws to the recommended torque may lead to moisture or dust entering the MC-i4.

IMPORTANT NOTE: To activate the MC-i4 on the CDMA network using the Topcon data plan, you must first cancel your existing contract with your CDMA provider (either Verizon or Sprint). This MUST be done prior to entering in the provisioning request in Topnet Live Manager.

Information needed before configuration:

  • MC-i4 Serial Number
  • Modem Serial Number, also called the IMEI/MEID number (see Capture modem serial number section in this document for instructions on obtaining the modem serial number)
  • ICCID Number from Topcon SIM card (19 digit number that starts with 8931)
  • Topcon SIM card installed in the MC-i4
