I topped up my Thai ph.No 3 times last month in TH but if only extended 90 days from last top-up I will have lost my No. when visiting TH again in FEB next year.

(I don't care about the small balance on my SIM but I would prefer to keep my Thai phone No.)
It depends on your main promotion. if you switch to the SIMPLE SIM promotion on DTAC the loads seem to stack. Few months ago I found that 3 x 50 baht gave me +270 days. YMMV
