cklimmUncle Lim, here are some unverified suggestions to solve your problem.
Please call POEMS SG, before trying any method. I have not tried any method, so I am sorry that it may not work.
1) Do you have a DBS, OCBC Singapore, or UOB Singapore savings account with access to internet banking website? Bill payment to Phillip Capital may be available in only internet banking website of DBS, OCBC Singapore, or UOB Singapore. Being a smaller bank in Singapore, internet banking website of Maybank Singapore may not have Phillip Capital as a bill payee. Or;
2) Try to ask POEMS SG, whether you can transfer SGD 1.00 via FAST to the following business account of Phillip Capital. I know that this account is meant for Telegraphic Transfer. Mention to POEMS SG that you have no other options to pay SGD 1.00 to POEMS SG (no trading account yet, so cannot use Electronic Payment for Shares).
Worst case scenario, you may have to perform Telegraphic Transfer from your savings account In Malaysia, to the following business account of Phillip Capital.
It is more of trial and error, Uncle Lim. Just try, and please let us know your successful outcome. Good luck, Uncle Lim.

Being old and lazy, unker ended up using FSM Singapore dah, at least the registration process was a breeze.
