SIM Card Size
Your mobile network operator / wireless carrier will need to provide a SIM card for use with their service; SIM cards are not included with the Teradek Node.
The Node's slot accepts a Mini-SIM (2FF) form factor SIM card (sometimes called a "Standard SIM", "Regular Size SIM" or "Normal Sized SIM") with dimensions of 25 mm x 15 mm.
SIM card adapters allow the use of either a smaller Micro-SIM (3FF) with dimensions of 15 mm x 12 mm, or a Nano-SIM (4FF) with dimensions of 12.3 mm x 8.8 mm, within the Mini-SIM slot on the Node.
A Micro-SIM and Nano-SIM converter is included with each Node -- do not try to use a Micro-SIM or Nano-SIM directly in the Node without an appropriate adapter!
