Overview
Simsup is a privacy-focused telecommunications vendor specializing in anonymous SIM cards and eSIM profiles that require no identity verification. Operating since 2019, the service caters to users seeking pseudonymous phone numbers for calls, texts, and mobile data without surrendering personal documents. The shop stocks three core product lines: physical anonymous SIMs priced between €8.95 and €38.95, data-only eSIMs spanning €1.80 to €413.00 depending on data allowance, and a premium €80 simsup-branded SIM capable of storing up to 15 eSIM profiles. Delivery claims are ambitious, physical cards reportedly ship globally within days, while eSIM activation is instant after payment confirmation.
The platform emphasizes ownership over rental: users buy numbers outright rather than subscribing to recurring carrier contracts. This model resonates with privacy advocates, journalists, travelers, and crypto-native individuals who treat phone numbers as disposable operational security tools rather than permanent identifiers.
Privacy & KYC
Simsup sits at KYC Tier L1, fully anonymous. No government ID, passport, selfie, or even email address is mandatory. The checkout flow accepts pseudonymous payments in Monero, Bitcoin, Lightning Network, fiat, and cash, letting users complete transactions without linking financial identity to telecom service.
However, the privacy picture contains sharp contradictions. The site's own privacy policy discloses collection of "personal identification information (Name, email address, phone number, etc.)" during order placement, newsletter signup, and browser cookie activity. Data is stored in an Icelandic data center and retained for three months post-order before deletion, with anonymized accounting records preserved indefinitely. The policy explicitly mentions marketing emails and data-sharing with unnamed "partner companies" for promotional purposes, language that clashes with the homepage's "no invasion of privacy" branding.
- IP logging: Confirmed via cookie and browser data collection
- Email requirement: Optional for orders; mandatory for newsletter
- Tor access: Available, though effectiveness against stated logging is unclear
- Jurisdiction: Unknown operator location; domain registered through NameCheap with Cloudflare proxying
This disconnect between marketing claims and documented practices explains the directory's stark 0/100 privacy score, the anonymity of payment rails is undermined by backend data collection that many no-KYC competitors simply do not perform.
Supported assets & payments
Simsup's payment flexibility is a genuine strength. Monero features prominently as the recommended option for confidential settlement, with Bitcoin and Lightning Network offered for faster, lower-fee alternatives. Traditional fiat and cash payments accommodate users outside crypto ecosystems or those needing plausible deniability in funding sources.
Product pricing is straightforward: entry-level data-only eSIMs start at €1.80, anonymous physical SIMs begin at €8.95, and the dedicated-number anonymous eSIM runs €29.95. Top-up credits for existing lines range €5.00–€14.00. Notably, several items including the €29.95 anonymous eSIM and €80 multi-profile SIM show as out of stock intermittently, suggesting inventory constraints or supplier dependency.
Community reports indicate simsup may function as a reseller rather than direct carrier, with one user noting 180-day number lifespans and pricing markups consistent with white-labeling from established roaming providers. This is not inherently problematic but affects support responsiveness and number longevity expectations.
Security & custody
As a non-custodial telecom service, simsup does not hold user funds beyond immediate transaction settlement. SIM cards ship physically or deliver as QR codes for eSIM provisioning, placing operational control entirely with the purchaser. The multi-profile SIM supports Cloud Enhance, SIM toolkit, and Android OMAPI configuration methods, appealing to advanced users managing multiple numbers.
Third-party validation offers mixed signals. Scam Detector assigns an 86.1/100 trust score citing valid HTTPS, six-year domain age, and absence from blacklists. Conversely, Cunicula's directory notes "unknown jurisdiction," "none on record" audits, and self-funded operation, transparency gaps that elevate counterparty risk. The 1/100 trust score in this directory reflects these structural opacity concerns rather than active fraud evidence.
User experiences diverge significantly: physical SIM buyers praise fast shipping and responsive support, while eSIM customers report activation failures, QR codes failing to render post-payment, and numbers that support internet but not voice/SMS routing. The discrepancy suggests physical fulfillment may be more reliable than digital provisioning.
Who it's for, verdict
Simsup occupies a niche for users prioritizing pseudonymous acquisition over long-term privacy architecture. It suits travelers needing temporary numbers, journalists sourcing SIMs without institutional billing traces, and crypto holders spending Monero on practical infrastructure. The open-source tooling and no-signup checkout lower barriers for technically capable privacy practitioners.
Yet the service is poorly matched to threat models requiring robust data minimization. The privacy policy's explicit data collection, marketing consent framing, and opaque corporate structure create liabilities that pure no-KYC competitors avoid. Users seeking anonymous SMS verification specifically should note community reports of inconsistent WhatsApp compatibility and 180-day number expiration, limitations that dedicated verification services like Crypton.sh or sms4sats may not share.
At 7/10 overall, simsup delivers functional anonymity at the point of purchase but falls short of the privacy guarantees its branding implies. Treat it as a convenient reseller for physical SIM procurement, not a hardened operational security platform.
