An underground online market sells European SIM cards from €5 to €80 in tightly regulated countries. Behind the price tags lies a structured grey economy.
Prepaid SIM cards from multiple European countries are circulating on a parallel market, sometimes legally obtained, often via fraudulent channels. Buyers—ranging from cybercriminals to privacy-conscious individuals—use them to validate online accounts, hide identities, or bypass restrictions. This trade reflects a complex interplay of national regulations, scarcity, and the growing demand for disposable digital identities. Prices vary sharply: from €5 in Poland or Portugal, where controls are weak, to €80 in Switzerland, where regulations are strict. Beyond resale, renting SIMs through “SMS gateways” generates recurring revenue streams for vendors. This economy exposes both the gaps in telecom oversight and the high value of anonymity in digital ecosystems.
Price Geography Mirrors National Regulation
Resellers’ price charts show a clear pattern: SIM card value is driven by the legal restrictions of its country of origin.
-
Poland / Portugal: €5–6, no systematic ID checks.
-
UK: €7 despite tighter rules.
-
Spain / Romania: €8–10.
-
France: €22 with strict ID verification.
-
Italy: ~€45 under reinforced registration.
-
Belgium: €55.
-
Switzerland: up to €80 with rigorous oversight.
Low-regulation countries make SIMs cheap and abundant. In stricter markets, scarcity turns them into a prized commodity for those seeking discretion.
A Business Built on Margins and Rentals
The model is simple: buy cheap, sell high. A Polish SIM may cost under €1 from a local carrier and resell for €5–10.
But renting SIMs is far more profitable. Vendors store hundreds in specialized modems and grant remote access for sending/receiving SMS. This “SMS gateway” model transforms each SIM into a recurring revenue asset. The longer a SIM stays active, the more income it generates.
Prices fluctuate by country and logistics. Delivery delays through services like SDEK or PEP reveal a fragile yet organized cross-border supply chain. Russia-bound deliveries cost more due to sanctions and monitoring.
This rental model appeals to spammers and cybercriminal groups automating account creation. Thousands of active numbers can be generated on demand without ever handling the SIM physically.
Uses at the Edge of Privacy and Fraud
Legitimate uses:
-
Extra privacy layer for individuals wary of tracking.
-
Businesses testing localized services.
-
Circumventing geo-restrictions.
Criminal uses:
-
Account validation on Google, WhatsApp, Telegram, Facebook, fintech platforms.
-
Mass phishing campaigns and spam.
-
Banking fraud.
-
Identity spoofing via foreign anonymous SIMs, which complicates investigations.
High-priced SIMs from France, Belgium, or Switzerland are more attractive for fraud. These numbers pass credibility checks more easily compared to low-cost Polish SIMs.
A Grey Zone Expanding Despite the Law
The anonymous SIM trade exposes persistent gaps in Europe’s telecom oversight. While states enforce stricter rules, uneven national legislation creates exploitable loopholes. Traffickers exploit these inconsistencies to fuel a cross-border trade.
Every new regulation simply shifts supply to more permissive countries. EU harmonization efforts are slow and fragmented. Meanwhile, thousands of cards flow unchecked, escaping both carriers and regulators.
At its core, this market highlights the strategic value of digital identity. In a world where a phone number remains a gateway to countless services, controlling distribution is becoming a key cybersecurity challenge.
Behind the advertised prices, the anonymous SIM market reflects a fragile balance between privacy needs and criminal exploitation. Until the EU enforces strict KYC harmonization, these cards will continue fueling underground networks. The open question: can European cybersecurity neutralize this trade without eroding ordinary users’ freedom?
