    You can check coverage maps on the official websites of 3, Vodafone, and Eir. Additionally, Roami provides a coverage checker tool on our product page. For real‑world performance, refer to Ookla Speedtest Connectivity Report which shows city‑level data – e.g., Limerick achieved 128.48 Mbps mobile download speed.

    Yes, Roami allows you to purchase multiple data packages in advance. You can store them in your account and activate sequentially via the app or QR code. Each package starts when you activate it, not when purchased.
  • Q4: Will I have a network signal with the eSIM in subways, deep valleys, or remote areas of Irland?

Deep valleys and remote areas (e.g., parts of Connemara) may have reduced coverage – Vodafone offers the best rural reach. For most tourist spots, 3 and Vodafone provide reliable service.
