I have searched the forums to try to find an answer to this question but could not find a thread on this. I apologize if this is a duplicate thread. Does the Model 3 cellular connection step down from LTE to 4g or 3g when there is no LTE reception? I often park in an underground garage that has ATT 4g repeaters but no ATT LTE signal. Will my model 3 have connectivity in the this garage when I get it next week?
