Coronium Review 2026

Coronium (coronium.io) is a mobile-proxy specialist that takes a deliberately different approach from the big residential-pool vendors. Instead of selling access to a shared, rotating pool of millions of IPs, Coronium rents you a dedicated physical 4G/5G/LTE modem with a real SIM card, located in a specific country and often a specific city. According to the site, each device belongs to a single user for the duration of the rental, so the IP history on that line is yours alone. The company says it has operated since 2020 and serves several thousand customers; its headquarters is not clearly stated on the site, and the main public contact channel is Telegram (@coroniumio) alongside live chat and email.

The product line is narrow by design. The core offering is dedicated mobile proxies; alongside that, the site references a residential VPN, IPv4 proxies, a fully managed device-rental tier ("Service Core"), pre-configured hardware sales, and a reseller program with a white-label REST API and USDC payments. There is no general-purpose residential, datacenter, or ISP proxy pool here, and no scraping/SERP API product. If you specifically want raw mobile carrier IPs with reputation control, this is the lane Coronium plays in.

On coverage, Coronium's own pages are inconsistent: the homepage advertises 10+ countries, the buy page says 20+, and other pages reference 30+ with city-level targeting. Treat the conservative 10+ figure as the safe floor. The buy page lists per-country monthly rates including USA $99, UK $69, Germany/France/Spain/Portugal/Netherlands/India $79, Italy $89, Australia/Japan $129, Poland $69, Brazil/Canada $99, Ukraine $34, Ireland $59, Georgia $50, and New Zealand $119. The marketed entry point is "from $5/day," and the site also offers weekly and 24-hour billing in addition to monthly, with a stated discount of up to 10% on orders of five or more ports. No total IP-pool figure is officially fixed; the site references roughly 10,000+ IPs per country, and third-party writeups cite varying numbers (one mentions 150,000+ IPs), so an exact pool size cannot be confirmed.

Feature-wise, the standout is control and isolation. You rotate IPs manually, on a schedule, or via API, with each rotation taking roughly 10-20 seconds and no cap on rotation frequency. The proxies support HTTP(S), SOCKS5, and OpenVPN, and the site advertises unlimited bandwidth, average speeds in the 10-30 Mbps range, and city- and carrier-level targeting (for example, Play, Orange, T-Mobile, and Plus in Poland). There is a dashboard with real-time monitoring, an API for rotation and port management, and a free proxy trial so you can test before buying. Payments are accepted via credit card (Stripe), Bitcoin, USDT TRC20, and account balance, which makes it crypto-friendly. A money-back guarantee is advertised, though the exact number of refund days is not clearly specified on the page, so the precise terms are worth confirming with support before purchase.

The dedicated-device model is the whole pitch: because the line isn't shared, the site advertises trust scores of 95-99% on major platforms, which is why the natural audience is multi-account operators, affiliate marketers, ad-verification and QA teams, social-media managers, and anyone who needs human-looking mobile traffic that survives risk checks. It is far less suited to large-scale scraping where you want millions of rotating IPs cheaply.

The caveats are real and worth weighing. This is a premium, comparatively expensive way to buy proxies on a per-IP basis, and the network is small relative to mainstream residential providers, so it does not scale to massive concurrent-IP workloads. Independent testing reflects this: ProxyBros reported roughly a 99% success rate on a test server and around 95% across nine major sites, but with average response times near 2 seconds (faster in Europe, notably slower in the US at around 2.6 seconds) and a network that strained under heavy load. Trustpilot reviews are mixed: several customers praise stable sessions and a clean dashboard, while others report functionality breaking and unresponsive support. The country count varies across the company's own pages, there's no browser extension, and the offering is mobile-only with no datacenter, ISP, or residential-pool fallback. We have not lab-tested Coronium ourselves; the figures above are vendor-published specs and third-party reports, not our benchmarks.
