As Satya Nadella once said, “Every company is a software company.”
In 2026, it feels more accurate to say every company is also becoming a communication infrastructure company.
Telarvo provides hardware equipment for SMS marketing and enterprise-grade bulk SMS marketing infrastructure designed for businesses that want control over deliverability, routing, and long-term scalability. The global A2P SMS market is projected to exceed 70 billion USD. SMS open rates still hover around 98%. Voice notifications can increase response rates by 30–40% in sectors like finance and logistics. Those numbers explain why businesses are no longer satisfied with simple cloud APIs.
With over 18 years in telecom and long-term cooperation with operators worldwide, Telarvo has built certified Voice & SMS gateway systems and multi-IP proxy network solutions that move messaging from “marketing tool” to “core infrastructure layer.”
Why Infrastructure Matters Before Marketing
Most companies start with SMS marketing channels provided by aggregators or cloud API services. It works at the beginning. Then throttling starts. Then blocking. Sometimes entire IP ranges get blacklisted. Carrier filtering tightens without warning.
This is the hidden layer behind SMS marketing channels.
Cloud-only systems offer convenience but limited control. Businesses relying purely on third-party routing cannot manage IP diversification, SIM rotation, or local number strategies.
Owning hardware changes that equation. It introduces routing control, SIM management, IP rotation, and traffic shaping. To control delivery rates, companies must first understand how to build multiple IP networks.
How to Build Multiple IP Networks for Scalable Messaging
What Is a Multi-IP Network Architecture?
A multi-IP network architecture distributes outgoing traffic across multiple public IP addresses. In practical deployment, this is achieved through SIM-based gateways connected to proxy routing devices.
Telarvo’s PROXY Gateway solution allows racks of devices, each operating with its own public IP via SIM cards. The system supports:
lPublic IP distribution through multiple SIM cards
lIP rotation logic
lProxy gateway infrastructure
lAnti-blocking mechanisms
lSOCKS5, HTTP, HTTPS proxy forwarding
This structure enables businesses to avoid overloading a single IP endpoint. It spreads traffic intelligently.
Why Multiple IP Networks Improve SMS and Voice Stability
Carriers monitor unusual traffic spikes. A single IP sending high-volume SMS or voice traffic triggers scrutiny. Multi-IP switching reduces this risk.
SIM rotation improves continuity. If one SIM reaches usage thresholds, traffic shifts automatically. Regional SIM deployment allows local routing. For cross-border campaigns, local SIM-based gateways reduce filtering probability and increase trust.
It is not complicated, but it requires proper hardware.
Hardware Required to Build Multiple IP Networks
Telarvo offers:
lMulti-IP Proxy Gateway devices
l4/8/16 Channel 4G LTE Proxy Routers
lRack-based SIM infrastructure
lSupport for SSH / SOCKS5 / HTTP & HTTPS proxy
Practical deployment looks like this:
lInsert SIM cards
lAssign routing rules
lConfigure proxy output
lConnect to SMS or Voice platform
Hardware Equipment for SMS Marketing: What Actually Matters
Hardware equipment for SMS marketing refers to SMS gateway devices, SIM pool systems, and routing servers that physically send and receive traffic through mobile networks. Telarvo provides enterprise-grade hardware supporting up to 5,440 SMS per minute and up to 512 SIM cards per system.
SMS Gateway vs SMS Modem vs Voice Gateway
SMS Gateway
lSMPP / HTTP API integration
lUp to 5,440 SMS per minute throughput
lAuto SIM rotation
l512 SIM capacity
lReal-time SMS receive
This is designed for large-scale messaging operations.
SMS Modem Pool
lUSB 2.0 / 3.0 connection
l8–64 ports
lDirect PC sending
lSuitable for verification codes
GSM MODEM pools break the old rule that multi-port devices require desktop-only setups. Laptops can now operate them.
Voice Gateway
lUp to 32 concurrent calls
lIVR support
lCall statistics including ASR, ACD, PDD
lSIP v2.0, RFC3261 support
lCodecs G.711, G.729, G.723
Voice and SMS integration under the same infrastructure avoids fragmented systems.
Technical Indicators Buyers Must Evaluate
lSMS per second throughput
lSIM capacity
lHot swap support
lAnti-SIM blocking mechanism
lIMEI modification capability
lFirmware upgrade options
lReal-time SIM status monitoring
Telarvo hardware holds CE and FCC certifications. Deployment spans over 200 countries. API, SMPP, and SIP support are standard. These are not marketing lines. They are compliance realities.Businesses using Telarvo hardware have scaled up to 5,440 SMS per minute throughput, proving cost savings and increased deliverability over time.
Hardware alone, though, does not complete the system. The next step is how to send bulk voice messages efficiently.
How to Send Bulk Voice Messages Efficiently
Bulk voice messaging requires a stable voice gateway infrastructure.
Telarvo’s Voice Gateway supports mobile-to-VoIP routing and VoIP-to-mobile termination. It integrates with call center systems and supports automatic voice response.
Step-by-Step Voice Campaign Flow
lUpload contact list
lConfigure call intervals
lSet SIM rotation rules
lLaunch campaign
lMonitor ASR and call completion rate
Call statistics matter. ASR and ACD determine whether traffic is profitable. The system supports up to 32 concurrent calls with automatic SIM switching.Upload your contact list, configure call intervals, and use SIM rotation rules to avoid throttling with specific examples of logistics or financial campaigns.
Common Use Cases
lLogistics notifications
lPayment reminders
lEmergency alerts
lE-commerce order confirmations
lSchool or hospital broadcast systems
Voice reminders have increased repayment rates by more than 25% in financial operations. That number is not trivial.
SMS and voice complement each other across SMS marketing channels. A hybrid strategy tends to outperform single-channel campaigns.
SMS Marketing Channels: Cloud vs Hardware-Based Models
SMS marketing channels fall into four categories:
lDirect operator routing
lCloud API providers
lSIM-based local gateways
lHybrid multi-IP models
Cloud APIs are easy to start with. Hardware-based systems offer control and long-term cost efficiency.
Hybrid infrastructure reduces cost per SMS, allows IP flexibility, diversifies carrier exposure, and supports local number deployment. Local SIM cards increase message acceptance rates in many markets.
Telarvo supports two models:
Solution 1: Purchase Telarvo hardware and connect to its routing platform.
Solution 2: Use existing equipment and connect through Telarvo’s technical configuration.
The hybrid model reduces cost per SMS and avoids the throttling issues common with cloud-based APIs.
SMS Modem Providers
Telarvo modems come with anti-blocking mechanisms and real-time SIM monitoring, which provide better stability in high-volume traffic than competitor solutions.
Common Market Problems
lUncertified devices
lLimited firmware updates
lNo technical support
lIP instability
