I'm still on Hotlink FAST 3.0 plan. Should I quickly change to Hotlink Internet 365 and subscribe to 365 days unlimited?

I've been doing the RM5 top-up for a long time. It's has RM350 credit in it and don't know what to do with it...

Main line with DIGI at the moment. will be using Digi/Hotlink Internet most of the time depending on coverage/speed.
