Noosy SIM Card Adapter Kit
An economical SIM Card Adapter Kit.
One of the more common connection issues associated with custom LTE router builds can be traced to a misaligned SIM Card.
As with any SIM Card adapter, it is important that the SIM card fits properly into the adapter. This often requires sanding the small tabs/tits off the edges of the SIM card until it fits perfectly into the adapter–not a loose fit, but definitely not a tight one. Sand down the sides of the SIM Card using an Emery sanding board or piece of sand paper laid flat on a desk or surface.
A tight SIM card can and will prevent it from laying flat. When the unit is pushed into a SIM card slot, one end of the SIM card can rise (unnoticeable), resulting in a poor connection between the SIM card and the pins in the SIM slot.
