How SIM Card Router Works? Mobile Router with SIM Card Slot

The OutdoorRouter SIM card modem routers use contemporary Nano SIM cards, the same size SIM cards as used in most mobile phones.

SIM Card Measurements

There are three different sizes of SIM cards, including Standard SIM, Micro SIM, and Nano-SIM.
The Standard SIM card size is 1″ long by 0.6″ wide (25x15mm).
The Micro SIM card is half the size of a standard SIM card – 0.6″ long by 0.5″ wide (15x12mm).
The Nano SIM card is 40% smaller than the micro-SIM card – 0.5″ long by 0.3″ wide (12.3×8.8mm).

Please turn off the router power before inserting or taking out a SIM card.

Firstly, use the SIM pin to push the pinhole gently until the SIM card holder pops out.

Then, put the primary SIM card on the first slot. Make sure notch in the inside direction and pins face down. There is only one correct way to settle the Nano SIM card into the SIM cardholder.

Finally, carefully reposition the SIM card holder in the slot and push it back gently.

Sometimes the 4G SIM router might be unable to detect the SIM card. The Mobile status shows this or a similar contents error message of “SIM card unavailable.”

To fix the SIM card error, firstly, please verify if the SIM card is inserted correctly, then check if the SIM card is clean, especially on the golden contacts. For example, if there is dust/dirt/oil on the SIM card, you can follow the below tips to clean the SIM card.

• Wipe the gold SIM card contacts gently with a soft cloth to remove dust or oils.
• If unable to clean the specks of dirt, use a soft rubber pencil eraser to clean the gold SIM card contacts and a soft cloth to wipe away any eraser residue.
• The old SIM card might have oxidation on the golden contacts. You can use rubbing alcohol to remove oxidation. Dampen one end of a cotton swab with rubbing alcohol. Then gently rub the alcohol against the gold contacts on your SIM card. Continue cleaning the contacts until all of the oxidation is gone.
