30 Day Tourist SIM - Data & Voice

[alt]

Hi All,

When we landed in Swampy last year (Dec 2015) for our annual 1-month holiday to LOS, we were able to purchase a 30 day data (Think 10GB?) / Voice / SMS SIM there and then from the counter (Could have been AIS... can't remember)

 

Does this still exist? I see 15 day etc. but ideally we want a 30 day.

 

Wondering if this no longer exists? Any advise would be appreciated. We just want a pre-pay 30 day Data / Voice / SMS.

 

Many thanks.
