We are installing a Max HD4. We are using 2 Verizon and 2 AT&T cards. Was wondering if I could set this up with the Verizon that I have received and later install the AT&T when they come in? Or should I wait till all for card are installed? Didn’t know if as easy as powering down inserting the new cards and powering back up.
This is doesn’t matter. You may install HD4 with existing cards on hand. Our sim slot are hot swappable. You no need to power down the entire unit to insert new sim card.
