How fast does the text really need to go out?

Within about a minute, because that is while the customer still has the phone in their hand and has not yet dialled the next business. A reply an hour later reaches someone who has already booked elsewhere. The MIT and InsideSales lead-response research points the same way, though it is US B2B and directional, not a Singapore benchmark. The entire value of the automation is that it hits that first minute every time without you having to notice the miss.

Is texting someone back after a missed call allowed under PDPA?

Yes, because you are replying to a person who just contacted you, which is a service response, not unsolicited marketing. Singapore's Do Not Call rules under the PDPA, run by the Personal Data Protection Commission, target marketing sent without consent. Keep the reply about their enquiry, do not roll the number into a promo list without consent later, and offer an opt-out. This is not legal advice, so confirm with the PDPC guidance.

What if the customer wanted to talk, not text?

Then they will say so, and you call them back knowing it is worth it. The text-back does not replace calling. It buys you time by holding the customer in a conversation so they do not vanish to a competitor before you are free. Plenty of customers will happily finish the whole thing over text or WhatsApp and never need the call.

Will it annoy people to get an automated message?

Not if it reads like a real person and arrives fast. Someone who just failed to reach you is relieved to hear back, not irritated, as long as the message sounds human and helpful rather than like a stiff corporate auto-reply. Write it in your own voice, keep it short, and it lands as good service.

Do I need special phone hardware for this?

No. It works with a mobile, a landline, or a virtual business number, because it triggers on the missed call rather than needing a particular handset. The setup connects to your line, detects the miss, and fires the message. You keep the phone you already use. If you only fix one thing about how your business handles the phone, make it this. Turn every missed call into an instant reply and a booked slot on your calendar, so the customer who reached out never has to give up and dial the next name on the list.
