RoxyProxy shows a live counter on its homepage: how many mobile lines are currently available, out of how many exist.

That is the most honest thing a mobile proxy provider can display, and almost nobody does it.

Why a Stock Counter Is Genuinely Rare

Mobile proxies are physically constrained in a way residential pools are not.

Each dedicated line is a real SIM in a real device. There is a finite number of them, and when they are all rented, there are none left until somebody stops or more hardware arrives.

Most providers hide that. You buy, and then discover you are waiting, or that what you got is shared rather than dedicated.

Showing the number, including when it reads zero, means admitting the constraint publicly. A provider willing to display an empty shelf is a provider not quietly overselling.

One City, Deliberately

The infrastructure is private and located in Bordeaux. That is the entire map.

Naming a single city is about as specific as a mobile provider can be, and it tells you the hardware genuinely exists somewhere rather than being a line in a country list.

For anyone who needs a French or EU mobile address, that concentration is a feature. It is a limitation only if you needed somewhere else, in which case you know immediately rather than after a purchase.

Unlimited API Rotation

Rotation is driven through an API with no cap on how often.

API driven rotation matters for automation. If your system can trigger a new address at the moment it detects a problem, rather than waiting for a timer or a person, you can build recovery into the workflow rather than handling it manually.

Both SOCKS5 and HTTP are supported on dedicated lines.

Benchmarks and OS Fingerprint Handling

The site publishes benchmarks and describes OS fingerprint features.

Worth understanding what that addresses. A mobile address tells a site your traffic comes from a phone. If everything else about your connection says desktop browser, the story does not hold together, and inconsistency is exactly what detection looks for.

Aligning those signals is a real technical concern. Our user agent checker shows a slice of what your own setup currently announces, which makes the point quickly.

Private Infrastructure Means Something Here

The phrase private infrastructure is doing real work, because a large share of this market resells.

A reseller buys capacity from whoever operates the hardware, adds a margin and sells it on. When something breaks at the device level, they report it upward and wait, exactly as you would.

Running your own modems in your own location means you fix it. On the day a line goes down, that is the difference you actually feel, and it is invisible on every other day.

Who It Fits

RoxyProxy suits anyone needing a French or EU mobile address, automation that benefits from API driven rotation, users who want to know stock is real before paying, and people whose targets check more than the IP.

Who Might Look Elsewhere

One city is a narrow map. If you need addresses anywhere else, this is not your provider.

Limited stock also means availability is genuinely finite, so plan around the counter rather than assuming capacity.

Final Verdict

RoxyProxy is a small, honest operation that publishes the constraint most of this category hides.

Dedicated French 4G lines from real infrastructure in one named city, unlimited API rotation, both protocols, published benchmarks and a live stock counter.

There is a short trial available. Take it, and if the lines are in stock when you need them, you have found a provider that is not overselling what it has.
