I switched from Telstra to aldi this year and haven't noticed any difference except i save enough from the switch to buy a nice eyepiece every two months
I use the 25$ a month deal, never use all the data and it all rolls over. I think i have 100gb in the bank now
I stream redbull tv for mountain bike action, watch vids no probs, dont ever use the wifi at home because my phone is faster. Its a no-brainer for me, even out in the sticks it doesnt seem any different. Canberra has 5G now, and i dont need that so aldi is fine
It uses Telstra network.
