Every SMS is the same 160 characters on the wire, but the routing, compliance surface, and deliverability profile are wildly different depending on what you're sending. A 6-digit OTP into Indonesia takes a different route through our platform than a travel-advisory SMS into Argentina or a payout-confirmation into the Philippines. This index walks through the common use cases we see, so you can match your workflow to the right starting point. Every use case runs over the same REST API — a 12-line Python integration is all you need.
Use cases
2FA coming soon
Two-factor authentication SMS — lowest-latency routes, per-country template-approval guidance (US 10DLC, India DLT), fallback patterns, and session/code lifetime best practices.
OTP delivery coming soon
One-time passcode delivery at scale. Deliverability patterns by country, what to do when carrier-rejected, how to design the 6-digit code + expiry message for GSM-7 to avoid falling to UCS-2.
Appointment reminders coming soon
Healthcare, salon, service businesses. How to honor quiet hours per destination (§ 7 UWG in Germany, PROFECO in Mexico, PECR in the UK) and reduce no-shows with a reliable T-minus-24hr reminder.
Alerts & monitoring coming soon
PagerDuty-style incident SMS for ops teams. Highest-priority routing, sub-200ms p50 to on-call phone numbers in most countries, redundant path failover.
Travel SMS coming soon
Flight updates, hotel bookings, itinerary changes, multi-country broadcast. Includes roaming considerations, country-of-phone-vs-country-of-traveler routing, and USDC/XMR-funded balance for privacy-conscious operators.
Remittance corridor coming soon
Payout-confirmation SMS for remittance flows. Specialized routing into high-volume corridors (PH, NG, MX, IN, ID) with the delivery receipt webhook wired into your ledger reconciliation.
Crypto exchange notifications coming soon
Deposit/withdrawal confirmations, login-from-new-IP alerts, withdrawal-approval 2FA. Natural fit for smsroute because your infra bill is payable in the same crypto your exchange already handles.
SMB client messaging coming soon
Small-business client comms: invoice reminders, delivery updates, support replies. No monthly fee, no seat-based pricing — pay per message, top up with crypto as needed.
Which route profile does smsroute pick?
Transactional (OTP, 2FA, confirmations). Routed through lowest-latency paths with highest-priority carrier treatment. Typically sub-200ms p50 to the handset; success rates 98.5%+ across our 11 priority markets. Sender-ID treatment follows per-country rules: alphanumeric in Europe, 10DLC long codes in the US, DLT-registered headers in India.
Service notifications (appointments, alerts, status updates). Same routing as transactional but with quiet-hours enforcement surfaced at the country-page level. You can override quiet hours for genuinely time-sensitive operational alerts (a server down doesn't wait for 08:00 Mon-Sat), but the defaults are safe.
Marketing (promotional, lifecycle, retention). Requires documented opt-in and honors destination-specific opt-out registries (Bloctel in France, REPEP in Mexico, NDNC in India, DND 2442 in Nigeria). We route these through paths that expect STOP/unsubscribe replies and won't put your account in a spam-filter list at an operator.
