I just did the same yesterday. Took almost 24 hours for the linkage request to be approved (just got the approval 5pm just now). The linkage approval was not accompanied by email or SMS. I had to check every hour for updates.

Also prior to linkage approval , I transferred SGD 1000 via TransferWise (last night) to the CIMB SG account. By the time the linkage was approved, I can already see the SGD 1000 inside, with account status "active". Not sure if I just got lucky, or the "active" is not really active. Still pending CIMB Clicks SG activation code to be received. If by Thursday I still don't get the code then I might redo the initial transfer from CIMB MY.

1) To test the theory that it can/can't be done
2) Parallel work while waiting for SG-MY linkage
3) Penny pinching. CIMB MY->SG would've costed me an extra RM30 (effective exchange rate that day was 3.08 vs 3.05).

Eh? I thought CIMB SG is the more cost effective one? Isavvy has SGD500 minimum balance requirement, while FastSaver has none.

Anyway, would like to add to the wealth of info in this thread on SG account opening:

1) Opened CIMB MY account at local branch (3pm 21/9 Monday)
2) Opened CIMB SG account online via CIMB SG website (5.30pm 21/9)
3) Initiated linkage of CIMB SG to CIMB MY via CIMB Clicks MY
4) Initiated Transferwise transfer SGD 1000 into CIMB SG account (11pm)
5) TransferWise transfer SGD 1000 completed (9am 22/9 Tuesday)
6) Linkage of CIMB SG to CIMB MY completed. CIMB SG account status shows "active" already when I checked. Still pending activation code for CIMB Clicks SG (5pm)
7) Performed SGD 1 from CIMB MY to CIMB SG for KYC (as advised on page 1).
8) Received call from CIMB SG for identity verification. Clarified with officer that CIMB MY "active" is just linkage active, not account active. (11am 23/9 Wednesday)
9) CIMB Clicks SG activation code received. (2pm).

Yes. Account type/name is FastSaver, which is what almost everyone in this thread applied (if they went the CIMB route).

@Ramjade got it right. I only got a call from CIMB SG after I did the SGD1 transfer from CIMB MY. TransferWise SGD1000 was successful but did not prompt the CIMB SG call.
