The base device is free and always will be. Pro adds professional plugins, managed relay infrastructure, encrypted cloud storage, industrial IoT integration, and enterprise-grade connectivity - operated by IT and More Systems under German contract law.
All plugins are bound to your ESP32-S3 eFuse chip ID via Secure Boot. Subscription covers all updates and security patches for the selected period.
Upgrade from 128 to 512, 1024, or unlimited contacts. All ratchet states in PSRAM, zero-latency switching.
On-device AI via Anthropic, Mistral, or self-hosted. Smart replies, summaries, context awareness - all E2E encrypted.
Send messages at a set time or on recurring schedules. Encrypted at rest until send time. Offline queue support.
Hidden contact list behind a secret key combo + PIN. Both lists independently encrypted, forensic-resistant.
Device boots into a realistic SSH terminal. Enter a command sequence + passphrase to reveal the messenger.
Early access to releases, 24h security patches, beta channel, and rollback to any previous signed firmware version.
Dedicated support hotline, guaranteed response times, setup assistance, ongoing operations support, and guided updates.
Quantum-safe cloud backup for message history and contacts. AES-256-GCM with ML-KEM-768 key exchange. German servers.
Zero-Knowledge queue auth, Shamir's Secret Sharing across relays, and steganographic transport to resist censorship and seizure.
Retrofit electronic payment into existing vending machines and automats via UART, RS-485, RS-232, USB, I2C, SPI, or Power over Ethernet.
4G/5G data SIM operated by ITMS. Multiple data tiers, hardware-isolated baseband with physical kill switch.
Voice flatrate (national/international) + data. ITMS handles carrier interaction. M.2 LTE module required on device.
No monthly billing surprises. Pay once for 12, 24, or 60 months of updates and access. Connectivity and cloud plans are billed monthly or annually with volume discounts.
One upfront payment covers all security patches and feature updates for the plugin for one full year.
Two years of continuous updates. Save compared to two annual subscriptions. Recommended for regular users.
Five-year coverage. Best for enterprise deployments where long-term stability and predictable costs are required.
Private relay networks ensure that no message, no data point, and no metadata ever leaves your organization's controlled environment. Combined with biometric authentication, every action is accountable and every transmission is attributable - without exposing identities to the relay.
Retrofit any existing vending machine, automat, or point-of-sale terminal with encrypted electronic payment. The SimpleGo Payment Module connects via standard industrial interfaces and turns legacy hardware into a modern, secure payment endpoint.
The customer tops up their digital wallet online or in-store at the vendor's website. At the vending machine, they tap their device via NFC or connect via Bluetooth to pay. The transaction is encrypted end-to-end and verified against the customer's biometric identity (fingerprint or Face ID) plus a PIN as two-factor authentication.
For age-restricted products (tobacco, alcohol), the integrated AVS (Age Verification System) confirms the buyer's age through biometric identification before authorizing the dispensing mechanism. No personal data is stored on the vending machine itself - verification happens against the encrypted identity token in the customer's wallet.
All transaction data is transmitted via encrypted SMP relay. The vending machine operator receives real-time sales data without ever seeing customer identities. Full audit trail for tax compliance, zero personal data liability.
Business customers only. Payment retrofit requires a commercial contract with IT and More Systems. Installation, certification, and ongoing maintenance included in the service agreement.
IT and More Systems operates as your telecommunications service provider. We lease SIM cards, manage carrier relationships, and deliver pre-configured devices with 4G/5G connectivity - all under a single contract. One KYC, unlimited devices.
Your company completes identity verification once with IT and More Systems. After that, order any number of SimpleGo devices - each pre-configured with a 4G/5G data SIM registered to our company. The baseband processor on each device is physically separated via USB (no DMA) and disconnectable via hardware kill switch.
Employees receive fully configured devices ready to use. No individual SIM registration, no carrier contracts per person, no personal data shared with mobile network operators.
KYC required. All connectivity contracts require identity verification. Business and private customers accepted. Commercial telecommunications service under German law (TKG).
Dedicated relay servers operated by IT and More Systems - from a single shared-tenant SMP relay to a fully isolated multi-server GoRelay deployment with Shamir's Secret Sharing. All under German contract law, full SLA, DSGVO-compliant by architecture. Pricing and rental models coming soon.
All managed infrastructure contracts are concluded under German civil law (BGB), with a formal written agreement, clear SLA, and defined termination rights. Data processing agreements (DPA / Auftragsverarbeitungsvertrag) included as standard.
Relay rental pricing is structured in tiers based on server dedication, message volume, and security features (Triple Shield, Shamir distribution). Contact us for a tailored offer.
KYC required. Managed infrastructure contracts require full identity verification. Business and private customers both accepted. No anonymous contracts.
The SimpleGo App Store will allow you to install, purchase, and manage plugins directly from the device - verified by your unique chip ID, no account required.
Each plugin is signed with a key bound to your device's eFuse ID. Free plugins are available for all registered devices. Paid plugins are verified against your chip ID on every boot. The store itself is accessible via your SimpleX address - no email, no account.
Pro features ship as the base device reaches production readiness. Follow development on GitHub or get in touch to discuss managed infrastructure, fleet connectivity, or industrial IoT deployment.
