SMS gateway comparisons — cloud APIs, modem stacks, and Android SIM paths
Neutral guides that put architecture, total cost, deliverability, and ops side by side. Android SMS Gateway is priced by devices and SMS volume; you supply phones and operator airtime.
Score your corridors
Domestic high-volume OTP often favors local SIMs; multi-country long-tail often favors cloud CPaaS.
Model full TCO
Include airtime, phones, plan allowances, number fees, and spare capacity—not list price alone.
Prove with dual POC
Same templates, staff canaries, two weeks of P95 delivery and support tickets before you commit.

Cloud / CPaaS side
Integrates in software only. Strong for multi-country catalogs, rented numbers, and teams that refuse handset ops. Bills usually track destinations, channels, and inventories—model peak months carefully.
Android SIM side
Your phone and SIM are the radio path. Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Best when domestic volume, reply-to-local numbers, and airtime economics dominate—and ops can watch devices.
