What works in Cuba — 2026 platform list under the US embargo

Inside Cuba, the main bottleneck for overseas services is international bandwidth cost and latency, not political enforcement. ETECSA mobile plans remain expensive relative to Cuban wages — the real cost of using a network access tool is data charges, not the tool itself. For exit nodes, Miami / Mexico City / Bogotá deliver lowest latency (60-150ms) as nearby Caribbean-NA hops; European exits run 200ms+ but stay more stable during politically sensitive periods. OFAC-restricted services (Netflix, Apple, ChatGPT) need an overseas exit so the target sees a non-Cuban IP; payment is the harder problem — Cuban cards are blocked at every major payment gateway, so users rely on overseas bank accounts or crypto workarounds. Telegram MTProto proxies are the most common speedup inside Cuba. AI services need overseas phone numbers (Cuban prefixes globally blocked by AI providers). During major political events (e.g., July 2021 protests) ETECSA shuts down connectivity outright — no tool overcomes infrastructure-level blackouts.
