Simpatti expire about 7 days after expiry.
I only charge in small amounts to keep active. A re-charge lasts 6 weeks approx. then another re-charge so there is plenty of credit for the next trip. I use my for Data also so 150,000rp ($15) lasts about 10 days. I don't know what those other cards run at in respect to calls and data.
Going in less than a week. I have those scratchie cards but have not been very successful with them. They link to Optus Australia and I get a service that is not the right one so I re-charge on the net.
