Which Ubigi plan should you pick?
For a short city break of 3–6 days, the cheapest plan at $29 will cover Maps, WhatsApp and casual browsing. If you’re spending one to two weeks travelling around Sao Tome and Principe, step up to a mid-tier plan — usually the strongest value on a per-GB basis in Ubigi’s Sao Tome and Principe lineup.
If you plan to work remotely, stream video daily, or use your phone as a hotspot, lean towards a larger bundle. The unlimited plans cost a premium but make sense for heavy users who don’t want to track usage.
One thing to note: Ubigi Sao Tome and Principe plans are data-only. You won’t get a local number, but your existing SIM handles calls and texts as normal — messages, WhatsApp and FaceTime all work over data.
