Been trying for weeks. I could not subscribe to mobile internet via "100#.
Number is in active period.
Balance is enough.

Kept getting:
Yr request failed due to technical issues. Try again later or call 123 for assistance.

Please advise.

Hi Fulvian,

We are sorry for the inconvenience. Have you tried to subscribe via Hotlink Red App for mobile internet?

Thank you.

Anything under "2 Mobile Internet" in *100# doesn't work.
But "3 Monster Bytes Promo" does work, however I don't need that much quota, I just need longer pass period.

I had not tried the Red App, but I will do try it once my current 1-day Monster Bytes expires.
