Phoenix International offers the SIM Plug, a device for exchanging subscriber identification module (SIM) cards without risk to machine-to-machine (M2M) devices. Exchanging SIM cards can be costly and time-consuming from a change in wireless carrier or from damage. Most cards are not adequately protected and are vulnerable to dust, debris, water, and warping. SIM cards needing to be changed in an entire fleet of equipment can incur substantial cost and risk. The SIM Plug holds a standard 15- x 25-mm (0.6- x 1.0-in) SIM card and provides a rugged, weatherproof connection to the M2M device. Cards can be quickly and easily exchanged without exposing sensitive electronic components. Available SIM options include embedded, solderable, and plug-in cards, which are accessible via a sealed-socket assembly from outside the enclosure.
