My parents are on the Starhub 4G4 plan currently (the $70 plan), paired with the free TPG/Circles Life sim. As they have minimal usage (under 30m call and under 200mb data) BUT would like to retain their Starhub number, which will be the cheapest plan (from any telco) for them to do so?
Both TPG and Circles don't allow porting unless I upgrade to the $28 plan. Prepaid plans also don't seem to allow retention of old numbers.
