Best eSIM for Port Louis in 2026
— Ranked by Real Performance

Port Louis operates on a surprisingly mature LTE network for Sub-Saharan Africa, with Mauritius Telecom (operating as My.t) and Emtel delivering genuine 4G LTE coverage across the capital's port district, financial centre, and caudan waterfront — typical real-world speeds of 20–45 Mbps down are achievable in central areas. For business travellers attending AFDB meetings or remote workers based in the Cyber Tower precinct, eSIM connectivity is reliable enough to support video calls without a backup SIM. The non-obvious insight: most international eSIM MVNOs route Mauritius data through Mauritius Telecom's wholesale arm rather than Emtel, meaning your roaming eSIM and a local SIM are often hitting the same congested backhaul during peak hours — provider choice matters less than plan structure.

• →Mauritius Telecom's My.t network covers approximately 98% of Port Louis's urban footprint on 4G LTE, with 5G trials launched in 2023 but not yet commercially available to roaming or eSIM subscribers.
• →Emtel, the second major carrier, runs its own independent fibre backhaul and is less congested than My.t during business hours — but fewer international eSIM providers hold direct Emtel wholesale agreements, making it harder to access via consumer eSIM.
• →Real-world LTE speeds in the Port Louis CBD typically range 20–45 Mbps download and 10–20 Mbps upload, but drop noticeably in the Central Market and Bus Station areas due to network density and older tower infrastructure.
• →Mauritius sits outside most pan-African regional eSIM bundles — providers offering 'Africa eSIMs' frequently exclude Mauritius or charge a significant per-MB overage, so a Mauritius-specific or Indian Ocean eSIM plan avoids costly surprises.
