Insert SIM Cards

The 5G router uses Nano (4FF) SIM card to connect to mobile internet networks.

Preparations

Use a Nano size SIM card (12.3x8.8mm) in the EZR35-5G router. If it's a new SIM card, please follow the instructions from the provider to activate it before inserting it in the router.

Please always turn off the power while inserting or removing the SIM card. Please use an unlocked and activated SIM card.

Insert A SIM Card

Turn off the router power before inserting or removing a SIM card.

1. Locate the SIM1 and SIM2 slots in the top right corner of the motherboard.

2. Hold the lid of the SIM card slot and slide left to open the cover.

3. Put a Nano SIM card in the SIM1 slot. There is only one correct way to settle the SIM card - the gold pins should be face down, and the notch should be on the top right corner.

4. Cover the SIM lid and slide right to lock the lid.

Check and Clean the SIM Card

If the router cannot detect the SIM Card:

First, confirm that the SIM card is already activated and has enough data allowance.

Then, check if the SIM card is inserted in the correct orientation and fully seated in its slot. The golden contacts should face down.

After that, inspect the SIM card's gold contact points to ensure they are clean and damage-free. If you notice any dust or dirt on the gold contacts, gently clean them with a soft, dry cloth or eraser.
