What OTP delivery looks like in USA.
Latency profile, peak-hour behaviour, recommended fallback chain, and the fraud signals our firewall watches in-market.
Typical latency window
Median 2.2 s with a 95th-percentile inside 8 seconds across operator-direct binds. Two-shot delivery confirmed by DLR.
Peak-hour behaviour
Operator throughput holds steady through local business peaks; throttling kicks in only during outlier mass-send events. BroadNet load-shapes per-MNO to avoid firewall blocks.
Fallback chain
Recommended fallback: Voice OTP after 30s no-delivery. Toll-free messaging used as a redundant short-code fallback.
Fraud signals we watch
STIR/SHAKEN-attested origination on voice fallback. Watch for short-code re-rental fraud and 10DLC campaign drift.
What you can — and can't — send.
Opt-in, opt-out, quiet hours, content restrictions, and the penalty regime for the USA market.
Opt-in
TCPA-compliant express written consent required for marketing. Transactional traffic permitted under the established-business-relationship exception.
Opt-out
STOP keyword honoured immediately and confirmed once. CTIA short-code monitoring audits compliance.
Quiet hours
Marketing A2P restricted to the recipient's local 08:00–21:00 window under TCPA.
Content restrictions
SHAFT-content categories blocked. 10DLC campaign brand must match the registered use case; toll-free traffic requires verification.
Regulator penalties
TCPA private right of action: USD 500 – USD 1,500 per violating message. CTIA can audit and revoke short codes.
Termination,
network by network.

Can I send marketing SMS in USA without prior consent?
No. Verifiable opt-in is required across every market BroadNet supports, with the consent source, timestamp, and channel logged. Transactional OTP and account-level alerts are exempt from marketing-consent rules.
