Pricing
No subscription fee. Usage draws from your prepaid IOSOR balance.
$1,000/ month usage
Top up from $20 anytime after access. Around USD 1,000 monthly platform usage we review tariffs and can assign closer support.
Prepaid balance
Top up once — SMS, voice, email, and number rental debit the same balance. No surprise invoices.
Rates that scale with you
Per-message and per-minute tariffs in your contract. Volume discounts when monthly usage justifies a review.
Who IOSOR is for
Clear fit for B2B teams that need messaging without surprise invoices — and honest examples of where to use it.
SaaS & product teams
Login codes, password resets, and account alerts with prepaid caps so OTP abuse cannot empty the wallet overnight.
Fintech & marketplaces
Transactional notices buyers actually open — payment confirms, dispute updates, seller pings — on routes fixed in your contract.
E-commerce & logistics
Shipping updates, delivery windows, and reminder bursts without juggling five vendors for SMS, voice, and email.
Agencies & white-label
Run client brands on your portal: sender identity, DIDs, and inbox under their name — you keep the ledger.
Support & field ops
Two-way SMS and inbound on rented numbers so agents reply where the customer already is.
Growing businesses
Start from a $20 prepaid wallet. Around $1,000 / month usage we review rates, volume, and closer support — no platform subscription.
What you gain working with IOSOR

Every send debits one wallet. No platform subscription. Top up from $20 — you see cost before volume runs away.
One stack under your brand

Swiss data posture
Hosting posture aligned with Switzerland. Built for nFADP and GDPR expectations on B2B messaging.
