Blogger Lester Chan notes that SingTel is now offering a micro-SIM as part of the multi-SIM package.
If you want a micro-SIM on SingTel's multi-SIM plan, you have to pay $16.05 a month for two SIM cards, and of the two, only one can be a micro-SIM card.
As he notes, the cheaper option is to pay $5.35 a month for a normal multi-SIM plan and cut one of the larger SIM cards down to size.
See the blog post for the full details. SingTel's microSIM plans are here (look under the Others tab).
