Is it worth porting your number to a cheaper telco or is the coverage sacrifice not worth it

I ported from a big telco RM88 plan to a cheaper RM35 plan last year and here's my honest verdict after 12 months. In the Klang Valley and most towns the coverage and 4G/5G speed are basically identical because many budget plans actually ride on the same network towers as the big boys, so I save RM50+ a month for zero difference in the city. BUT, and this is the real consideration, when I balik kampung to a rural part of Kelantan, the coverage did drop noticeably in the deep kampung areas where the premium telco still had a slight edge. My advice: check which network your chosen budget plan piggybacks on, ask people in your specific kampung which telco works there, and since number porting keeps your number and is reversible, just try it for two months, worst case you port back.
