Key Takeaways

  • WhatsApp SMS gateway searches: people mix Meta conversation pricing with SMS. Our plan is devices + SMS send volume on your Android SIM — not WhatsApp Business message tiers.
  • Operator SMS/MMS airtime is a separate bill from our service fee.
  • Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
  • Free canary: 300 SMS lifetime · 300 contacts · 1 device max.
  • Starter, Professional, and Business list Unlimited SMS as platform send volume; that is not unmetered carrier SMS or equate WA templates with SIM OTP.
  • Consent rules differ by channel — treat them separately.

Searches for a WhatsApp SMS gateway usually want one box that texts everywhere. This page contrasts cost models: Meta’s WhatsApp Business pricing versus an Android SIM SMS gateway. Related: When SMS still wins. Our pricing. WhatsApp pricing docs.

Priced by devices and SMS send volume. You use your own phone and operator SMS credit.

WhatsApp conversation fees and your prepaid SMS balance are not the same ledger — bundling them in one “gateway” pitch confuses buyers and finance.

They want OTP, alerts, or chat on whatever the customer opens. Channels differ: WA needs the app installed; SMS hits the radio number.

We are not WhatsApp Business pricing

Do not map our Starter/Pro cards onto WA tiers. Free is 300 SMS lifetime for canaries — not a Meta sandbox.

When Android SMS still wins

Users without WA, regulators that expect SMS OTP, or a local number customers already call — OTP.

Hybrid is normal

WA for rich chat; Android SIM for fallback OTP. Keep templates and consent per channel — comparisons.

FAQ

Frequently asked questions

Direct answers about whatsapp sms gateway.

Does SMS Gateway include WhatsApp Business API?

No. We send SMS/MMS via paired Android handsets. WhatsApp has its own cloud APIs and pricing — unrelated to our device/volume meters.

Is your SMS cheaper than WhatsApp?

It depends on country, volume, and whether users have WA. Compare total cost: our plan + your airtime vs Meta conversation fees + quality ratings — not a single slogan.

Can I use the same phone for both?

Technically a handset can run many apps; operationally keep OTP SMS isolated and follow each platform’s rules.
