MicroEsim does not provide a true unlimited‑data eSIM for Jersey. The only options for high‑speed data are fixed‑data plans that carry a hard cap, such as the Jersey Island eSIM – 30 Days / Total 30 GB or the Jersey Island eSIM – 30 Days / Total 20 GB. These plans allow 30 GB or 20 GB of 5G data over 30 days and then throttle speed to 128 kbps. Plans with “Unlimited 5Mbps” in the name give 1 GB per day of high‑speed data; once the daily quota is reached, the speed drops to 5 Mbps, so they are not unlimited either. For travelers who need a large amount of data without a hard limit, a fixed‑data plan may be more cost‑effective.
