Hey Legend

While reading through other posts, i notice that another customer found themselves in the situation whereby they lost connectivity (reason is irrelevant), and your advice was to have another SIM (replacement SIM) in hand if the situation arose again. Thereby maintaining connectivity. 

This is logical, so without having any issues myself with my SIM, i've ordered a replacement SIM (future proofing). My question is, how long will the replacement SIM remain operational without activation?.

If i put the SIM in a draw for 6months lets say (as of yet, auto renewal in place) then an issue occurs, will i be able to activate the SIM 3,6,9 months later. How long does the SIM remain viable without activation.

thank you in advance
