Roaming used to be a deeply manual, fragmented, and high-touch operational domain for mobile operators. Even though today’s roaming solutions ecosystem runs on standardized protocols, automated signaling exchanges, and well-defined partner procedures, the commercial side of roaming has not kept pace with that automation. Every operator still faces the same gap: the network processes are digital, but the revenue processes are not.
By 2025, roaming traffic has surged back to pre-pandemic levels and surpassed them, growing 18–25% YoY globally due to increased international travel and widespread adoption of eSIM-enabled devices. Despite robust signaling standards (Diameter, MAP, IR.21, IR.85, IR.73), operators report that 20–30% of potential wholesale roaming margin is lost due to silent roamers, incorrect partner distribution, anti-steering behavior, and commitment misalignment. The commercial layer of roaming is now one of the last un-automated areas in the telco value chain.
Wholesale roaming economics continue to depend on two fundamentally different pricing models; commitment-based and quality-based. Commitment traffic is predictable and easy to reconcile. Quality-based revenue, however, requires constant monitoring of KPIs, partner performance, subscriber behavior, and steering outcomes. Operators still rely on human teams to watch dashboards, interpret signaling anomalies, intervene in near real time, and prevent revenue leakage. But no matter how experienced the teams are, humans cannot react at the speed at which roaming traffic shifts, partners change their routing logic, probe patterns evolve, or eSIM-based arbitrage appears.
With more than 1.5 billion eSIM devices in active circulation, attachment patterns have become highly fluid, making revenue protection exponentially more complex. Operators increasingly acknowledge that 60–70% of margin-impacting roaming events occur within the first 30 seconds of network attach—far too fast for manual processes.
This is where the industry hits its operational ceiling. Traditional roaming platforms automate the transport, but they don’t automate the judgment: the high-frequency decisions that actually influence revenue, margin, and partner economics.
Bankai Infotech’s Unified Roaming Suite Was Built to Close The Gap
Unified Roaming sits above standard roaming implementations and turns roaming into an intelligent, revenue-maximizing layer. While most roaming platforms stop at enabling mobility, Unified Roaming adds the decisioning and value-added services operators need to protect margin, optimize partner distribution, react to evolving subscriber behavior, and automate actions that previously required manual monitoring.
With Unified Roaming, operators don’t just run roaming; they govern it. Commercial logic, steering intelligence, signaling analytics, welcome messaging, fraud detection, usage control, and wholesale economics all operate in one unified system, allowing real-time actions instead of post-event corrections.
The result: roaming stops being a cost center managed through periodic clean-up and becomes a revenue engine driven by automation, context, and intelligence.
Here are some of the salient features of Bankai Infotech’s Unified Roaming suite:
Dynamic Steering of Roaming
Unified Roaming delivers a complete Steering of Roaming system that supports 2G to 5G, including IoT and M2M traffic, and is fully IR.73 compliant. The platform handles both Static Steering and Dynamic Steering, giving operators granular control across roaming retail teams, wholesale teams and customer experience teams.
Static Steering uses LBTR (Large Value Transfer System) and SRDC (Sender/Receiver Data Center) based rules where preferred, non-preferred, forbidden, and percentage-based routing ensures baseline control of outbound traffic.
The real value emerges in Dynamic Steering, where Unified Roaming applies Retail Steering, Wholesale Steering and Subscriber Based logic in real time.
Retail Steering: uses pack based and usage-based conditions so consumer roamers attach to networks that best match their bundle or live consumption.
Wholesale Steering: applies commitment based and DIOT (Direct Inward/International Outbound Termination) based routing to protect commercial obligations and distribute traffic intelligently across partners.
Subscriber Based steering: applies specific profiles for prepaid, postpaid, VVIP, VIP, HVC (High Value Customer), MVC (Medium Value Customer) and LVC (Low Value Customer) users, allowing the operator to safeguard high-value customers and manage segment-wise QoE.
Operators adopting AI-driven dynamic steering typically report:
- 8–12% uplift in wholesale margin through optimized commitment usage.
- 20–40% reduction in anti-steering losses via real-time anomaly detection.
- 5–7% QoE improvement for high-value roamers.
As operators transition into 5G Standalone (5G SA) roaming, steering must evolve to support:
- Network slicing–based steering
- QoS- and SLA-based routing for enterprise roamers
- IoT-specific profile steering where device context shapes routing
Unified Roaming is architected to support these next-generation requirements.
Unified Roaming strengthens all of this with customer experience management features such as low time to attach, subscriber tracing and VVIP or VIP monitoring, while maintaining 99.999% operational accuracy for national and international steering. The decision engine is supported by AI analytics that interpret attachment behavior, usage trends and device patterns to guide stronger decision making and give operators clear visibility into how steering choices influence commercial and network outcomes.
The system can be further expanded using powerful Add Ons including:
- Commercial Plugins for live commercial inputs
- CRM Plugins for subscriber context
- Border Roaming Controller Plugin for accurate routing near borders
- Commitment-Based Steering for automated traffic balancing
- Roaming Automation for policy execution
- Roaming Insights for deep reporting and partner intelligence.
Together, these capabilities turn Unified Roaming into a complete roaming VAS platform designed to control, optimize and evolve outbound roaming for every subscriber category and every network generation.
Welcome SMS and Service Demarcation
When a subscriber roams into a new network, they need immediate confirmation of connectivity and cost awareness. At the same moment, the operator faces a critical cost challenge: every signaling event and data session generates MSU (Message Signal Unit) and DSU (Data Service Unit) charges through IPX/GRX networks, regardless of whether the activity is revenue-generating or not. For operators with 8-12% of subscribers roaming, these costs scale quickly and can exceed $1–3 million annually for mid-size operators.
Unified Roaming triggers Welcome SMS based on destination level wholesale costs, partner priorities. and live steering rules. Messaging aligns with commercial exposure, bundle mapping, routing preferences. and partner tier so operators control what is communicated at attach. Delivery uses SMS, app channels. or captive portals and supports multi-lingual formats.
Service Demarcation addresses the MSU-DSU cost leakage by monitoring subscriber wallet balance and credit status. When a user has insufficient balance, our Unified Roaming proactively sends an SMS notification prompting recharge and temporarily blocks outgoing SMS and data services. This prevents low-balance subscribers from generating unrecoverable IPX/GRX signaling charges.
Operators frequently see:
- Significant reduction in unrecoverable signaling charges
- Higher prepaid recharge conversions triggered by low-balance notifications
- 30–40% lower bill-shock complaints when Welcome SMS is cost-aligned
Snapshot
- Welcome SMS aligned with wholesale costs and partner context
- Multi-lingual message support for subscriber communication
- Service Demarcation prevents MSU-DSU charges for subscribers with insufficient balance
- Proactive balance notifications with SMS and data blocking
- Cost protection by eliminating unrecoverable IPX/GRX signaling charges
AI-Powered Signaling Analysis
Signaling patterns don’t follow simple rules. A subscriber probing multiple networks could be a phone scanning for signal, a user testing steering logic, or a device set up specifically to exploit rate differentials. Traditional rule-based systems cannot differentiate these because the behavior appears similar.
Our AI implementation solves this by recognizing deeper behavior patterns such as probe frequency, attachment timing, and switching intervals that reveal intent.
The platform learns what silent roaming looks like versus legitimate low-usage travel. What anti-steering tools do versus normal network selection. What eSIM arbitrage looks like versus someone legitimately managing multiple profiles for work and personal use.
What Unified Roaming’s AI models detect:
- Silent Roamers: Subscribers with valid roaming packages who avoid chargeable events, producing signaling load without revenue..
- Anti-Steering Tools: Visited networks manipulating attachment flows override home-operator steering.
- eSIM Arbitrage: Instant profile switching, silent churn indicators, unauthorized secondary SIM usage, and adoption trends.
This intelligence feeds directly into steering. The platform spots the behavior, routes that subscriber to partners where your agreements account for variable patterns, protects your margin before the first call gets rated.
Industry data indicates:
- Silent roamers make up 25–35% of roaming SIM activity in some markets.
- eSIM-based arbitrage is projected to grow 3–5x by 2026, driven by travel eSIM apps.
- Anti-steering is becoming increasingly sophisticated as visited networks attempt to retain inbound volumes.
Unified Roaming’s intent-level analytics give operators a decisive edge over legacy systems relying on static thresholds.
Border Roaming Gateway (BRG)
In border regions where subscribers can inadvertently latch onto neighboring country networks with or without crossing the border, operators face revenue leakage and customer dissatisfaction from unintended roaming charges.
Modern 5G macro-cells worsen this, with studies estimating up to 20% of unintended roaming originates from border propagation effects.Regulators in South Asia, GCC, and Eastern Europe have elevated unintended roaming to a top-three consumer complaint category, increasingly requiring operators to demonstrate proactive prevention measures.
Bankai Infotech Unified Roaming ‘s Border Roaming Gateway identifies devices operating in designated border zones and removes them from roaming services, preventing false roaming events. By correlating subscriber location with network attachment patterns, BRG distinguishes genuine cross-border movement from proximity-induced connections. This protects subscribers from billing disputes while ensuring operators maintain accurate revenue attribution.
BRG acts as a “customs and immigration checkpoint” for roaming traffic: validating identity, context, and compliance, before allowing signaling and data to cross borders.
Additionally, BRG provides insights into border-region mobility behavior, helping operators optimize commitments, negotiate better IOT terms, and evaluate coverage enhancement opportunities.
Call Correction
Inbound roamers often misdial international numbers due to incorrect country codes missing digits, or habits tied to their home network’s dialing conventions. Unified Roaming’s call corrector intercepts these calls, reads the home country context, figures out what they meant to dial, and completes the call correctly.
This capability prevents churn among high-value customers—particularly enterprise roamers who account for 12–18% of roaming revenue globally—and reduces customer care volumes for dialing-related issues.
Capabilities include:
- International dialing corrections
- Emergency number translations
- Home operator support routing
Convergence is the Future of Roaming
The telecom technology market has a critical gap. Service Demarcation, AI-powered signaling analytics, intelligent probing detection: these are the needs the industry recognizes but no platform delivers in a unified suite. Most operators still patch together legacy vendor systems that cannot share context, operate in real time, or transform detection into action.
UNIFIED ROAMING closes that gap.
Unified Roaming prevents revenue leakage by design. Service Demarcation reduces unrecoverable MSU-DSU operational costs. AI detects silent roamers, anti-steering, and eSIM arbitrage in real time. BRG eliminates false roaming disputes. Dynamic Steering protects margin on every attachment.
The industry is shifting toward Roaming 3.0. A convergence of real-time charging, AI-driven partner intelligence, eSIM mobility behavior, and context-aware decisioning. Operators that succeed in this era will treat every attach, every probe, and every anomaly not just as a network event, but as a commercial decision point.
We built our Unified Roaming suite with a conviction: stopping losses and generating new revenue are not separate goals. Silent roamers trigger retention offers. Border proximity reveals coverage expansion opportunities. Low-balance detection drives prepaid bundle conversions. Probing behavior informs wholesale pricing negotiations.
Every prevention mechanism becomes a revenue channel.
