Use a micro-SIM in an Airwall Gateway 100g (v2.1.x and v2.1.5)

Help if your Airwall Gateway fails to properly recognize the micro-SIM when inserted.

Solution

Use a SIM carrier to install the new micro-SIM in a Airwall Gateway 100g. The carrier allows the micro-SIM card to maintain better contact with the modem.

Cause

The punchdown micro-SIM is thinner than the old, full-sized SIM used to be.
