I see, do u need to pay the rm100 (upfront payment) when u first subscribe to the sim only package? Tbf, the router+sim package actually have the 30days-trial return policy, tho I need to pay the upfront payment first. What I didn't quite sure is whether I would get the rm100 back or it would be burned just like that if I were to return the modem within 30-days using the policy. I tried asking the tm agent I'm dealing with on wa, the answer she gave was quite ambiguous, but I'm 70% sure she said that I wouldn't get back that payment. Weird.

Also, I thought existing streamyx user didn't need to pay the upfront payment. Not in my case tho, got told that the promo had already ended so need to pay. Anyone knows whether this is true?

I also confirmed this with tm agent, she said it is available. Tho in my case, it seems that the upfront payment will be used as the bill payment of the 30-day trial.. Which is kinda strange for me as I am currently a streamyx user (I read that streamyx user doesn't need to pay the upfront)

U should try ask directly tm for confirmation
