Each tier maps to a specific plan and provider for Antigua and Barbuda.
Light user
Maps + messagingIf you only check maps and send messages in Antigua and Barbuda, budget 4GB for 7 days. Airalo offers the 5GB plan at $40.80 on FLOW. Airalo provides the best app experience for tracking your light data budget in real time. Per-GB cost is higher than Nomad.
Moderate user
Social + browsingThe moderate profile (1.5GB/day for social media, maps, and light browsing) needs 11GB over 7 days in Antigua and Barbuda. Airalo routes through FLOW's 4G LTE network with the 20GB plan at $164.45.

Buy one tier above your estimate if you add video calls or camera translation.
Heavy user
Streaming + callsHeavy travelers in Antigua and Barbuda (streaming, video calls, hotspot) use 21GB+ over 7 days at 3GB/day. Holafly's unlimited plan at $18.00/day on FLOW's 4G LTE network removes the data cap. Total cost: $126.00 for 7 days. Holafly wins this tier on unlimited availability and 24/7 live chat support.
