Tools
SMS Deliverability Pre-Flight Linter
Paste a message, pick destination countries, and catch link-shortener flags, ALL-CAPS ratio, missing opt-out keywords, GSM-7→UCS-2 segment jumps and registration flags before you send.
Sender-ID & Registration Rules by Country
Look up whether alphanumeric sender IDs are allowed, need pre-registration, or aren't supported across ~40 countries, with the registration regime and a cited basis for each row.
Anonymity Threat-Model Matrix
Pick an adversary and get an honest yes/partial/no read of what a shared-sender SMS API actually hides — and what it never can.
Multilingual Opt-Out Footer Generator
Compliant, natively-phrased opt-out footer text in 15 languages, plus the exact character and segment cost of adding it.
Crypto Top-Up Network Fee Comparator
Compare typical on-chain network fees across BTC, ETH, USDT, XMR, LTC and SOL for a chosen top-up amount. Editable snapshot defaults, not live data.

DLR / SMPP Error-Code Lookup
Search every SMPP 3.4 command_status code and standard DLR state — hex or decimal — with meaning, typical cause and what to check next.
SMS Throughput / TPS Campaign Planner
How long will your send take? Recipients, segments and TPS in — drain time, per-day batch schedule and required throughput out.

SMS Volume Cost Planner
Build a multi-market destination mix - volume, parts, GSM-7/UCS-2 - and get the honest all-in figure: published US rate, floor bound elsewhere, competitor delta if you paste a quote. All client-side.
MCC-MNC / Mobile Network Lookup
Search 626 sourced E.212 allocation rows - MCC, MNC, country, network - with an honest MNP disclaimer: allocations, not live lookups.
SMS Send-Window Planner
