Tools for people who send messages.
Free tools to plan a launch, test an integration and troubleshoot delivery, with no sign-up. Most run in your browser on public standards such as GSM 03.38, SMPP v3.4 and E.164. Five use BroadNet's own coverage and list-rate data: the Country Launch Planner, the Verification Cost Explorer, the Coverage × Compliance Explorer, the SMS Cost Estimator and the Channel Cost Comparison.
41 tools
Country Launch Planner
Pick a market, channel, sender type and use case to get the regulator and documents, sender-ID lead time, direct operators, price band and fallback path, as a downloadable launch brief.
Open toolSMS Fraud Workbench
Run labelled sample traffic (OTP, smishing, pumping, spoofing, grey route) through a firewall and see the verdict, reason, latency and action from the enterprise and the operator side.
Open toolVerification Cost Explorer
Model channel mix, encoding, resends, fallback and fraud to see the spend and the cost per completed verification, not just per message.
Open toolSMS Segment Calculator
Detect GSM-7 vs UCS-2 encoding, count segments and characters left, and see exactly which characters force Unicode — with an optional cost estimate at your own rate.
Open toolSMPP Error Codes
Search every SMPP v3.4 command_status value by hex or symbolic name, with a plain-English meaning and the likely cause and fix.
Open toolMCC / MNC Lookup
Find the Mobile Country Code and Mobile Network Code (ITU-T E.212) behind an operator — search a curated GCC, MENA and global subset by MCC, MNC, country or operator.
Open toolSMPP DLR Decoder
Paste an SMPP delivery receipt or pick a stat value to decode the final message state, the err field and every parsed field, per the SMPP v3.4 spec.
Open toolWebhook Signature Validator
Compute and verify an HMAC webhook signature (SHA-256 or SHA-1) with the Web Crypto API — paste payload, secret and signature and see match or mismatch. Nothing leaves your browser.
Open toolErlang C Calculator
Size a contact centre: enter call volume, handle time and a target service level for required agents, occupancy and ASA — plus a CPS × ACD concurrent-calls helper.
Open toolGSM-7 / Unicode Checker
Paste any SMS text to classify every character as GSM-7 basic, GSM-7 extension or Unicode-only, with a per-character table pinpointing exactly which characters force UCS-2.
Open toolTPS Calculator
Throughput planner: enter message volume, TPS and segments per message to get total time to send, messages per hour and a completion ETA — standard math, shown in full.
Open toolOTP Cost Estimator
Estimate monthly OTP spend and effective cost per successful OTP from your volume, delivery and retry rates and your own per-message SMS and voice rates. Your rates only.
Open toolcURL Command Generator
Build a ready-to-run cURL command from a method, URL, headers, JSON body and Bearer token, with one-click copy and a messaging-API send preset.
Open toolDeveloper Utilities
A small bundle of everyday converters: Unix timestamp ↔ ISO date, Base64 encode/decode, a UUID v4 generator and an E.164 phone validator — all client-side.
Open toolSMPP PDU Decoder
Paste the hex of an SMPP v3.4 PDU to decode its 16-byte header — command_length, command_id (with name), command_status and sequence_number — plus the submit_sm / deliver_sm body-field layout.
Open toolSMPP Session Simulator
Walk a full SMPP 3.4 session — bind, submit_sm, delivery receipt, unbind — with the real PDU bytes. Nothing connects, nothing sends.
Open toolSender ID Validator
Check an alphanumeric or numeric SMS sender ID against the GSM standard: the 11-character limit, the GSM 7-bit charset and the format rules that decide whether a network accepts, strips or rejects it.
Open toolPhone Number Formatter
Normalize a number to E.164 (+CCNSN) from a curated country table, see national and international display forms, and run an E.164 length plausibility check. Cites ITU-T E.164.
Open toolCodec Bandwidth Calculator
Pick a voice codec (G.711, G.729, G.722, Opus, AMR) and packetization interval to get bandwidth per call with and without IP/UDP/RTP overhead — the full math shown.
Open toolDelivery Rate Calculator
Enter sent, delivered, failed and pending counts to get delivery rate, failure rate and a clear breakdown — from your own numbers only, with a DLR reconciliation check.
Open toolSMS True-Cost Calculator
Compare two providers or routes on cost per delivered message — total spend divided by the messages that actually arrive. The headline rate can lie; this shows the real cost. Your figures only.
Open toolWebhook Payload Inspector
Paste a messaging webhook — a delivery receipt or an inbound message — to validate the JSON, detect the event type, and see every field explained in plain English. Runs in your browser.
Open toolMessage Template Previewer
Write an SMS template with {{variables}}, fill in sample values, and preview the resolved message in a phone-style bubble with live character count, GSM-7 vs Unicode encoding and segment count — flagging unresolved variables. Runs in your browser.
Open toolCoverage × Compliance Explorer
Search, filter and sort every market BroadNet covers — operators, delivery rate, latency, price band and sender-ID registration rules — in one interactive table, with per-country coverage and regulation deep-links.
Open toolAPI Request Builder
Fill in the fields and get a correct BroadNet SMS API request — POST /sms/sendSms with a Bearer token and a JSON body — plus copy-paste cURL, Node, Python and TypeScript SDK snippets, with the legacy HTTP API too. It builds the request; it never sends.
Open toolSMS Cost Estimator
Enter monthly volume, pick a destination country and type a sample message to get an indicative monthly SMS cost — real per-country reference rates times segments times volume. Get a quote for exact pricing.
Open toolSMS Marketing ROI Calculator
Enter your campaign assumptions — audience, conversion rate, order value and SMS cost — to project revenue, cost, ROI and ROAS. Your numbers only; not an industry benchmark.
Open toolNumber Insight
Enter a phone number to see its country, region, dialing code and E.164 formatting, plus the operators serving that market. For the live operator and line-type, use HLR Lookup.
Open toolBulk Number List Validator
Paste a list of phone numbers to normalize them to E.164, validate, de-duplicate and flag invalid ones — then copy or download the clean list. Runs entirely in your browser.
Open toolCampaign Link Builder (UTM)
Build a correctly-tagged UTM tracking URL for SMS, WhatsApp and RCS campaigns, with validation and an SMS-length check. Runs in your browser; nothing is sent anywhere.
Open toolSend-Window Planner
Pick destination countries to see each markets compliant marketing send window — quiet-hours-aware — converted to your own timezone, with an overlap across all selected markets. Guidance, not legal advice.
Open toolOTP Security Calculator
Configure an OTP scheme — length, character set, expiry, attempt limit — to compute its combination space, entropy and brute-force resistance, with hardening recommendations. Exact math.
Open toolWhatsApp Template Validator
Compose a WhatsApp Business template and validate it against public Meta structure rules — header, body, footer, buttons and variables — with a live preview. Final approval is Meta's.
Open toolA2P Compliance Checklist
Select a destination country and message type to generate a country-specific A2P SMS compliance checklist — sender ID, consent, timing, data protection — from published regulator and operator rules. Guidance, not legal advice.
Open toolChannel Cost Comparison
Compare the cost of reaching your audience via SMS, WhatsApp, RCS and Voice side by side — you set the per-channel rates (SMS can use a real country reference rate), ranked by total campaign cost. Cost is only one factor.
Open toolTwo-Way SMS Keyword Designer
Design inbound-keyword auto-reply rules (STOP, HELP, START and custom) for a two-way SMS number and simulate the conversation, with segment counts and compliance warnings. A design tool — it does not send real messages.
Open toolA/B Test Sample-Size Calculator
Enter your baseline conversion rate, the lift you want to detect, confidence and power to get the audience size each variant needs — so your SMS/WhatsApp A/B tests are statistically valid. Exact math; your baseline.
Open toolWhatsApp 24-Hour Window Calculator
Enter when a customer last messaged you to see when the WhatsApp 24-hour service window closes, with a live countdown and what you can send inside (free-form) vs outside (template) it. Reflects public Meta policy.
