Coronium review: dedicated 4G/5G mobile proxies with unmetered data

What is Coronium?

Coronium is a mobile proxy provider operating since 2020. Instead of a shared pool of IPs, it rents you a dedicated line: one physical 4G or 5G modem or phone with its own SIM on a real mobile carrier, hosted by an independent operator. Websites see a normal carrier IP that many ordinary phone users share through the operator's network, which is why mobile IPs are among the hardest to block.

What you get with each line:

• Unmetered data: traffic on a dedicated line is not counted, so heavy sessions cost the same as light ones.
• IP rotation control: change the IP on demand or automate it through the API.
• Protocols: HTTP(S) and SOCKS5, with OpenVPN listed in the technical specifications.
• Country and carrier choice: US lines on T-Mobile, Verizon and their 5G networks, the UK on Three, Germany on 1&1, O2 and Vodafone, and more.
• Extras: free proxy tester, proxy checker and DNS leak test, plus an MCP server for AI agents.

Support works by email, Telegram and dashboard tickets.

Who Coronium is for

• Multi-account management: a dedicated mobile IP per social or marketplace account, usually paired with an antidetect browser such as the one in our Dolphin Anty review.
• Ad verification and SERP checks: see ads, search results and AI answers as a phone user in the US, UK, Germany or another stocked country.
• Scraping strict targets: sites that challenge datacenter and residential IPs often treat carrier IPs more gently.
• Testing apps and local offers: a stable country-level mobile connection for QA.

If you need many countries at once or pay-per-GB rotation instead of a fixed line, compare our 711Proxy review and MarsProxies review, or browse the best proxy services.

Coronium pricing

You pay per dedicated line for a fixed period; the price depends on the country and carrier. Starting prices for lines in stock on 29 October 2026 (USD):

Carriers within a country differ: in the US a 30-day T-Mobile or Verizon line starts at $139 and T-Mobile 5G at $149. Data is not metered on any plan.

Stock moves fast: on the same day Spain, Italy, Canada, Brazil, Australia and several other countries showed "Out of stock now", and Coronium itself says most countries sell out within days. Confirm the carrier, region and final price in the dashboard before paying.

Why choose Coronium

The line is yours alone, so no other customer burns its reputation, and you are not counting gigabytes. The 24-hour plans (from $7) let you test a country and carrier against your real target before committing to a month. Rotation by API makes it practical for automation, and the 5G options in the US give you a choice of networks.

Good to know: refunds, stock and rules

• Refunds are narrow. Purchases are non-refundable if support confirms the proxy works; a refund is possible only when the proxy does not work and cannot be replaced. Money added to the account balance is not refunded.
• Prohibited sites: PayPal, banks and government websites; no refund if they are unreachable.
• Verification: Coronium may ask for ID and proof of payment if it suspects misuse, and may suspend accounts that ignore KYC requests.
• Stock: many countries are often out of stock; you can ask hello@coronium.io about availability.
• Use: legitimate tasks only; illegal use leads to suspension without refund. The terms are governed by Lithuanian law.
