MicroEsim does not offer a plan that provides truly unlimited high‑speed data for Saint Barthélemy. The plans whose names include “Unlimited” give a fixed daily allowance of 1GB and, once that allowance is used, the speed drops to 5000kbps. Travelers who require a larger quantity of data can choose one of MicroEsim’s fixed data plans, such as the 60GB for 60 days or the 30GB for 30 days, which continue to provide data at a reduced speed of 128kbps after the high‑speed allocation is exhausted. These fixed plans give a set amount of data that does not expire until the validity period ends.
