You don't have to pick a channel. Different customers reach for different apps, and a shop that answers on both meets people where they already are. The question isn't which one — it's when each one shines, and how to keep your records straight across both. This page answers both.
SMS vs WhatsApp, side by side
The honest comparison, without the marketing gloss:
| SMS | ||
|---|---|---|
| Reach | Every phone, no app needed | Anyone with WhatsApp installed |
| Customer setup | None — just a phone number | Needs the WhatsApp app |
| Starting a conversation | Send any message (to opted-in contacts) | Requires an approved template if outside the 24-hour window |
| Replying to an active chat | Always free-form | Free-form while the 24-hour window is open |
| Media | MMS — images, basic media | Rich: HD photos, video, documents, voice, buttons |
| Best when | Quick quotes, broad reach, customers you can't assume are on WhatsApp | Photo-heavy back-and-forth, international customers, richer conversations |
| Read receipts | Delivery status | Delivered + read receipts |

What stays identical across both
Here's the part that matters for accountability. However a message arrives, the parts that protect you don't change:
- One shared inbox. SMS and WhatsApp threads sit side by side. Your team doesn't switch tools or think about channels — they just answer customers.
- Per-message attribution. Every outgoing message, SMS or WhatsApp, is tagged with the teammate who sent it. No manual signing, no exceptions.
- One audit trail. Sends, edits, assignments, and handoffs are written to the same reviewable log regardless of channel. Pull the full history of a conversation and it reads the same whether it happened over text or WhatsApp.
- One off-boarding action. Revoke a teammate's access once and it covers every channel at once. Nobody keeps a back door through "their" channel.
The channels differ in how they deliver a message. They're identical in who's accountable for it. That's the point of running both through one inbox instead of two disconnected tools.
A customer who switches channels
It happens constantly: someone texts you for a quick quote, then sends photos over WhatsApp because the images are clearer. With two separate phones, that's two disconnected conversations and no single record. In Go2Msg, both threads belong to the same contact, both are attributed, and both land in the same audit trail — so the full story of that customer is in one place.
Pick a starting channel, add the other later
You don't have to launch both at once. Most shops start with the channel they already use — usually SMS on their existing number — and add WhatsApp once the team is comfortable. Because attribution and audit are identical, adding the second channel changes nothing about how your team works; it just gives customers another way in.
Do SMS and WhatsApp share one inbox or two?
One. Both channels feed the same shared inbox, and threads from the same customer are grouped under one contact.
Can I report on activity across both channels together?
Yes. Attribution and the audit trail are channel-agnostic, so you can pull a teammate's activity or a conversation's full history spanning both SMS and WhatsApp.
Is one channel more compliant than the other?
Each has its own rules — 10DLC/opt-outs for SMS, templates/windows for WhatsApp — and Go2Msg handles both. The audit and consent record is kept the same way regardless of channel.
