Key Takeaways
- Device health for WhatsApp vs an Android SMS gateway is a false friend: Cloud API has no handset battery. SMS does.
- WA on-call watches quality rating, template status, and phone-number display. SMS on-call watches last-seen, OEM, prepaid.
- Do not page a Pixel for a Meta quality dip. Do not open Business Manager for a sleeping SIM.
- We meter SMS devices and volume. We do not sell WhatsApp conversations. Operator airtime is the SMS path only.
- Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
Searchers want one device health checklist for WhatsApp vs SMS gateway. WhatsApp Cloud API does not run on your Pixel. An Android SMS gateway does. If you apply a battery-saver runbook to Business Manager, or a quality-rating runbook to a dock, you will page the wrong layer.
Service pricing is based on device count and total SMS sent through the gateway. Clarifier: WhatsApp vs SMS. Comparison: Cloud vs Android SMS. SMS dock list: API device health. Meta: Cloud API docs.
There is no OEM battery exemption for a cloud quality rating. There is no WABA for a phone in a drawer.
Cloud has no Pixel
Dual-stack products still have two health jobs. Dual-stack readiness.
Health by network
| Watch | WhatsApp Cloud | Android SMS gateway |
|---|---|---|
| Primary signal | Quality rating, template status | Device last-seen, DLR fail rate |
| Power | N/A (their servers) | Charge + OEM exemptions |
| Balance | Meta billing | Operator prepaid/postpaid |
| Identity | Display name / WABA | SIM MSISDN |
| Spare | Second number / backup WABA (their rules) | Second paired phone, plan slot |
WhatsApp: quality, not battery
Template pauses and user blocks are Meta’s ops. We do not sell those conversations.
SMS: the dock
You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance. Setup. Spare phone.
Fallback is two health jobs
If SMS is OTP fallback, the Pixel must be healthy while WA is also healthy — or you discover the spare during an outage. OTP.
Checklist
- Separate dashboards. Separate alert names.
- WA: quality + templates. SMS: last-seen + prepaid.
- Do not share a “device down” Slack channel without a prefix.
- Fallback path tested when *both* are green, then when WA is red.
- No invented unified health API.
Next steps
Rename the alerts this week. Then unplug the SMS phone and pause a WA template in staging — separately — so each page still makes sense.
