About the company

An enterprise operating in both Asia and the U.S. approached Rayobyte with a challenge: their existing residential proxy options were no longer reliable enough, available enough, or scalable enough to support the volume of publicly available data they needed.

Demand was growing fast, residential IP availability was shrinking, and detection tools were increasingly flagging residential IP ranges, making long-term investment in their pipeline unstable.

They needed a future-proof alternative.

The challenge

Mobile proxy buildouts are complex by default, and South Korea added several extra layers of difficulty. Most business stakeholders primarily operated in Korean, which created communication and contractual hurdles from the very start. Hardware imported into the country must meet strict telecom certifications before it can be used, so every device had to be vetted and approved.

Local carriers also impose firm rules on what they can sell to businesses, meaning we first had to understand each carrier’s limitations and then design our approach around them.

The technical landscape added its own complexity. Our infrastructure needed to support around ten different mobile hardware types, so we built custom software to standardize performance and ensure compatibility across all devices.

Carriers also enforce both hard and soft traffic thresholds per plan to prevent congestion on local towers, which requires careful planning. To maintain full compliance and avoid affecting consumers, our software continuously monitors traffic patterns and automatically scales usage down whenever necessary.

On top of this, the client needed:

• A stable long-term supply of high-quality mobile IPs
• Performance consistency at scale
• Compliance with all local telecom requirements

This wasn’t a plug-and-play deployment. It required custom engineering, regulatory diligence, and deep carrier-level understanding.

Our solution

Rayobyte built a fully compliant, carrier-approved mobile proxy infrastructure in Korea and the U.S., designed to give enterprises a stable, scalable alternative to shrinking residential IP availability.

Our approach focused on:

1.  Carrier-aligned hardware and network design

We worked directly within each country’s regulatory framework, sourcing certified devices, building infrastructure that met telecom requirements, and designing a deployment model that adapted to each carrier’s constraints.

2.  Custom software across 10+ hardware profiles

Because mobile hardware varies significantly by vendor, chipset, and carrier configuration, we developed our own orchestration layer to unify traffic management, monitoring, and performance controls across all devices.

3.  Intelligent traffic throttling

To avoid tower congestion and adhere to all carrier policies, our system actively monitors usage and automatically moderates bandwidth. This maintains compliance, prevents local overload, and ensures long-term stability.

4.  A future-ready replacement for residential supply gaps

The industry is reaching a breaking point with resi IPs. Detection tools monitor known residential ranges and block them more aggressively over time.

Mobile networks, by contrast, offer shared IP environments where a single IP often supports more than 10,000 real users. Blocking these IPs indiscriminately would disrupt genuine mobile customers, meaning this model provides much more sustainable long-term reliability.

5.  Replicable international deployment

Once we proved the model in Korea, one of the most complex telecom environments in the world, we replicated the system in the U.S. The same blueprint is now ready for any region, as long as a client has the need and the budget.

The results

These buildouts delivered immediate impact for both Rayobyte and our enterprise clients.

• Ultra-low latency for SERP scraping and AI workloads because our mobile hardware sits in the same rack as our scraping servers.
• Higher success rates thanks to carrier-native IPs that provide clean, compliant access to publicly available data.
• Massive scalability, with the infrastructure ready to support millions of daily requests across multiple countries.
• Full operational control, eliminating reliance on third-party residential networks with shrinking supply and unpredictable quality.

This combination gives our clients a competitive edge, especially in fast-moving sectors like retail and AI.

The impact

These deployments validated that mobile proxy infrastructure is not only viable but essential for the next generation of scraping, search analysis, and AI training pipelines.

They also proved that Rayobyte can:

• Build a compliant mobile proxy infrastructure in highly regulated markets
• Overcome language and carrier-level barriers
• Standardize operations across complex hardware ecosystems
• Deliver low-latency performance at enterprise scale
• Replicate this model globally

With two major international buildouts complete, we’re now equipped to deliver this capability anywhere our clients need it.
