Keep the +65 OTP path, or replace it?

Singpass and bank SMS still need a reachable number. Compare prepaid keep, postpaid keep, port, and drop-and-replace sketches.

Months you still need +65 OTP

Strategy to price

Prepaid monthly (SGD)

Postpaid monthly (SGD)

Port / admin one-time (SGD)

Replace OTP path one-time (SGD)

How this sketch works

Prices keeping prepaid, keeping postpaid, porting out, or dropping the number.
Multiplies monthly keeps by months needed and adds one-time costs where they apply.
Recommends the true minimum with no handicap for any path.

Dropping the number often breaks Singpass SMS and bank OTP until you re-bind contacts.
Check postpaid early-termination fees before comparing against prepaid.
