Full supplier and route analysis (direct vs aggregator)
Grey route and grey traffic identification
OTP channel benchmarking (SMS vs WABA vs RCS)

Number Verification API
Stop paying for messages that can't be delivered

HLR (Home Location Register) real-time number validation
MNP — current operator after number portability
Active/inactive status before message send
Roaming status for cost-aware routing
Bulk verification for database cleansing
🧹
Typical result
15–25% saved by removing dead numbers
Why DewTelco
We're not a platform. We're your messaging profit centre.
Most SMS vendors want you to send more messages. We want you to spend less per outcome — and we stake our reputation on the numbers.
🎯
Outcome-first consulting
Every engagement starts with your cost and conversion goals, not our product catalogue. We recommend the right channel mix, even if it means sending fewer messages.
🔗
Carrier-level relationships
Direct connections to MNOs and Tier-1 aggregators mean better routes, real-time delivery receipts, and rates that platform resellers simply cannot match.
📐
Channel-agnostic advice
SMS, WABA, RCS — we work across all three and help you allocate budget to the channel that delivers the lowest cost per conversion for each use case.

Most businesses reduce OTP delivery costs by 40–70% when switching from A2P SMS to WhatsApp Business API (WABA) OTP. The exact saving depends on your current SMS routes, volumes, and geography. DewTelco offers a free SMS spending audit to calculate your specific savings opportunity before you commit to any migration.
An SMS spending audit is a consultancy engagement where DewTelco analyses your entire messaging operation — including your supplier contracts, routing configuration, volume breakdown, grey traffic exposure, and channel mix. You receive a 30-page savings roadmap that identifies every cost-reduction opportunity, prioritised by impact and ease of implementation. Audits typically uncover 20–60% in recoverable spend.
RCS (Rich Communication Services) is the next-generation messaging standard built natively into Android devices. Unlike SMS, RCS supports verified brand sender IDs, images, video, carousels, CTA buttons, and read receipts — with no app download required. RCS does not directly reduce your messaging costs, but it dramatically improves campaign performance: businesses consistently report 3–5× higher click-through and engagement rates compared to plain SMS. The same send budget simply delivers far better results.
Number verification via network APIs — including HLR (Home Location Register) lookup and MNP (Mobile Number Portability) checks — validates whether a phone number is currently active, which network it belongs to, and whether it has been ported to a different carrier. By removing inactive or invalid numbers before you send, you eliminate charges for undeliverable messages and reduce fraud risk. Businesses that clean their lists first typically save 15–25% on their messaging bill immediately.
A2P messaging delivers the highest ROI for e-commerce, fintech, banking, healthcare, logistics, and retail — any business that needs to reach customers at scale with OTPs, order confirmations, delivery updates, appointment reminders, or promotional campaigns. DewTelco works with businesses across all sectors, from early-stage scale-ups to enterprise teams sending hundreds of millions of messages per month.
A standard WABA OTP migration — from BSP selection and Meta verification through to template approval and live traffic — typically takes 1–2 weeks. DewTelco manages the entire process, including Business Manager verification, WhatsApp Business Account setup, template submission, and parallel running with your existing SMS to ensure zero downtime during the switchover.
Yes. The initial SMS spending audit — covering route analysis, supplier benchmarking, and a preliminary savings estimate — is provided free of charge with no commitment required. If you choose to engage DewTelco to implement the recommended changes, we work on a shared-savings or fixed-fee basis depending on scope. You only pay once savings are measurably delivered.
