Do I have to ReJoin after being out of range

Hello All,

I am developing an GPS based data tracker with a WioE5 module to sent battery voltages, temperatures etc. to a NodeRed dashboard.

My question, do I have to rejoin the TTN network after being out of range or after repowering.
BTW I used Activation by personalization (ABP)

Thanks in advance,
Michel (from Belgium)
