Independent assurance for ambitious MVNOsMVNOs must deliver exceptional customer experiences while protecting margins and brand reputation. BluGem provides independent testing, fraud detection, roaming assurance and real-world service monitoring to help MVNOs validate performance, reduce risk and build customer trust.

Stop revenue leakage before it costs youEvery change to your systems, contracts or rates is a potential leak in your bottom line—and in today's complex environments, those leaks add up fast. Our end-to-end test solutions trace the full revenue journey, from device usage through switch and mediation to the customer bill, pinpointing exactly where margin is slipping away. Take immediate, targeted action to protect your profits and secure long-term growth.

Interconnection assurance, end to endInterconnection is where revenue, compliance and customer trust all meet and where a single misrouted call or mispriced rate can cost you dearly. Our test solutions give you the power to interrogate networks and routes with precision, exposing fraud, verifying billing accuracy and ensuring full regulatory compliance. Launch next-generation services like eSIM and OTT voice and messaging globally with total confidence.

Protect your network from fraud, scams and evolving threatsFraud is constantly evolving. From SIM boxes, OTT bypass and CLI refiling to scam messaging, spoofing and firewall evasion, operators face growing pressure to protect revenues, customers and brand reputation. BluGem provides global threat intelligence and real-world monitoring solutions that help identify vulnerabilities before criminals exploit them. Whether you need active fraud detection, SMS honeypot intelligence, firewall validation or assurance against international traffic abuse, our solutions help you detect threats faster, reduce losses and strengthen your defences.

Get to market faster, get it right first timeIn a fiercely competitive market, every product launch is a chance to win loyalty—or lose it. A single missed customer journey, miscalculated tariff or broken notification can derail months of work. We partner with Product Managers and Go-To-Market teams to build rigorous test plans that cover every scenario, pre-live and live. From promotions and tariff refreshes to roaming zones and spend-caps, we make sure your launch lands perfectly, on time and on brand.

Transform with confidence, not compromiseEvery new system, platform or migration brings opportunity and risk. A single discrepancy between legacy and new environments can disrupt service, corrupt data and damage customer trust.

We help you transform with confidence, rigorously verifying the accuracy and functionality of new systems against legacy benchmarks in both test and production, so change delivers progress, not problems.

Independent evidence. Regulatory confidence.Regulators expect proof, not assumptions. Communications providers face increasing scrutiny over billing accuracy, service performance and consumer protection. BluGem delivers independent, quantitative testing that provides clear evidence of compliance, validates customer outcomes and helps organisations demonstrate transparency, accountability and trust.

Independent oversight for national authoritiesSelf-reporting only goes so far, national authorities need independent evidence to verify that communication providers are meeting their regulatory obligations. Our test equipment interfaces directly with the network to deliver impartial, verifiable proof of compliance. From exposing SIM box fraud and interconnect bypass to tracking emerging schemes targeting internet and OTT services, we help regulators safeguard consumer interests and recover the tax revenues rightfully owed.

Precision testing for law enforcement supportNational security and law enforcement agencies rely on accurate network information to do their critical work and any inaccuracy can have serious consequences. BluGem's automated test solutions verify that network data is being supplied and interpreted exactly as it should be giving agencies the confidence to act on intelligence that's been independently proven.

Independent testing for quality and service assuranceDelivering reliable communications services requires more than laboratory testing. BluGem helps QA and test management teams validate voice, messaging, data, roaming and digital services using real devices, real networks and global test resources. Our independent testing solutions help identify issues earlier, improve service quality and increase confidence before launch.

Avoid surprises after launchThe cost of finding issues after deployment is always higher than finding them before release. BluGem provides independent testing that helps release teams validate services under real-world conditions, uncover hidden defects and gain confidence that new products, updates and platform changes are ready for customers.

Global app assurance, local user insightYour app needs to perform flawlessly on every device, every operating system and every network your customers use wherever they are in the world. Our scripted, repeatable tests validate functionality and usability in the live environment, while our global network of international testers delivers language validation and unbiased user feedback across countries and carriers. Launch with confidence that your app meets customer expectations everywhere it matters.

Real test events on real devicesAudits are only the beginning. BluGem’s Test Call Generation platform combines a global network of real devices with TÜV SÜD BABT approved timing and byte accuracy to execute strategic test plans that protect networks, billing integrity and customer experience. From 5G and VoLTE to satellite and IoT services, BluGem targets the areas where issues are hardest to detect, delivered either as a fully managed service or a system operated by your own team.

Testing and assurance for roaming and international servicesWhen customers roam, your reputation travels with them. BluGem assures roaming and international services across more than 100 countries using automated TCG units and a global Crowd Network of real users on real devices. Roaming zones, tariffs and welcome messages are validated against real customer journeys, with rapid results delivered through a fully managed service.

Every byte measured, every charge verifiedWhen customers pay for data services, every byte matters and so does every billing decision behind it. BluGem’s data assurance platform measures exactly what reaches the handset and compares it against network records to identify missing CDRs, incorrect byte counting, failed usage caps and mistimed allowances. Gain the independent insight needed to resolve issues quickly, protect revenues and maintain customer trust.

Timing accuracy you can certifyWhen CDR timing is off, bundles misfire, durations distort, and revenue leaks. Whether you need regulatory proof or operational peace of mind, BluGem's TÜV SÜD BABT approved timing system provides an accurate point to compare like-for-like against your network records across multiple feeds. Spot the discrepancies others miss and resolve them with confidence.

Every tariff, every bundle, validatedBill shock drives churn faster than almost any other complaint, and in a world of complex tariffs, bundle stacking, roaming zones and free app traffic, mistakes are easy to make and costly to fix. BluGem's approved tariff modelling system independently re-rates your mediated CDRs to expose discrepancies fast. Paired with our Test Call Generator, it gives you a true end-to-end view of billing accuracy, with expert analysis and real-time reporting.

The end of plastic SIMs, the start of new risksThe plastic SIM is on its way out, and your customers are already expecting a seamless eSIM experience at home and abroad. BluGem's global network of genuine eSIM-capable Android devices puts your provisioning to the test, comparing physical and eSIM journeys side by side, validating rating, profile changes and notifications, and surfacing any fraud risk before it reaches your customers.

Check the accuracy of notifications sent to customersSMS messages are far more likely to be read than email, making them one of your most valuable channels, and one of the most costly to get wrong. BluGem's global network of real devices automatically captures and validates your notifications, from roaming welcome messages and geo-fenced promotions to fraud alerts and balance statements. Verify delivery, content, timing and triggers with real-time screenshots of exactly what your customer sees.

Bypass detection fraudsters can't predictFraudsters are faster, smarter and more relentless than ever, bypassing interconnects, refiling CLIs and shifting traffic onto OTT platforms to evade detection and steal revenue. BluGem fights back using real subscriber SIMs, fixed lines and SIP clients across the globe, combined with a Global Crowd of 100,000+ users that continuously rotates traffic sources so fraudsters cannot predict or track testing activity. Detect bypass, CLI refiling and OTT fraud quickly with instant alerts and clear pass/fail reporting.

Independent intelligence on scams and spam targeting your networkScammers and spammers are constantly targeting your customers, and operators need an independent view of the threats reaching their networks. BluGem’s honeypot service quietly captures unsolicited voice calls and SMS, classifies activity against known scam and spam patterns, and provides the evidence needed to strengthen defences, support law enforcement and demonstrate regulatory compliance.

Are criminals finding ways around your firewalls?Deploying a firewall is only the beginning. Even with major investment, scams, bypass attacks and evolving threats still reach subscribers, and without independent validation it's hard to know how effective your defences really are. BluGem combines proactive controlled-traffic testing with passive monitoring to reveal how your firewalls perform against real-world attacks and highlight where updates are needed.

The most important calls on your networkFew obligations are as critical as connecting the public to police, fire and ambulance services, and failures have tragic, real-world consequences. BluGem independently verifies that emergency calls route correctly across CS, VoLTE, VoWiFi and 5G, at home and while roaming, on physical SIM, eSIM and no SIM. With affordable monthly programmes, location-ID checks and network fallback testing using real handsets worldwide, we help you prove every emergency call connects when it matters most.

The internet of things, assuredConnected devices are reshaping every sector, but a single glitch can stall adoption and erode confidence in your network. BluGem independently verifies the usability, functionality and communication accuracy of IoT services, from pre-launch snapshots to long-running heartbeat monitoring. With expert CDR analysis and a global testing footprint, we help you launch and grow your IoT proposition with confidence.

SIP, VoLTE and VoWiFi assuredPacket-switched voice gives customers a richer experience, but the more protocols you support, the more places errors can hide. BluGem methodically tests every combination of SIP, VoLTE, VoWiFi, GSM and PSTN at both origination and termination, on real Android devices and across our global network. From CS fallback and missing CDRs to roaming partner failures, we catch the issues before your customers do.

Broadband and PSTN assurance you can trustHome working, streaming and online gaming have pushed broadband usage to record highs, and at that scale, even the smallest billing error multiplies into serious revenue impact. BluGem independently validates ADSL, PSTN and broadband services with approved timing, full CDR reconciliation and accurate data tracking, so you can be confident every customer is billed correctly, every time.

Be ready when the authorities callWhen the authorities request subscriber data, there's no room for missing records or mismatched IPs. A single gap can mean fines, reputational damage or a criminal walking free. BluGem's IP Address Resolution confirmation product runs scheduled 24/7 data events across mobile and broadband, tracking internal and external IPs and correlating them to each SIM, so you can prove your Lawful Interception system delivers complete, accurate records every time.

Same product, different platform, real riskRoughly half your customers are on iPhone, yet iOS can behave very differently from Android. Different APNs, tariff configurations and app protocols all create platform-specific problems that can quietly cost you revenue and goodwill. BluGem's globally distributed iOS testers run any test plan you need on real Apple devices, fully reconciled against your network CDRs, so the experience is consistent whichever phone your customer chose.

Validate system functionality through defined test journeysUndetected errors don't just frustrate users, they can stop your product working altogether. BluGem combines automated test event generation with experienced multi-lingual crowd testers to validate scripted journeys against your specification, on real devices, in the locations and networks that matter. With evidenced defects, risk categorisation and a dedicated project manager, you launch faster and with confidence.

Unbiased end-user feedbackYou've invested in a great product, but does it actually feel right to the people who'll use it? Skipping usability testing risks missing your target audience, frustrating customers and damaging your brand. BluGem's international crowd network delivers unbiased, real-world feedback from a wide demographic, with evidenced reports and a dedicated project manager, so you go to market with confidence and the insight to keep improving.
