eSimfly does not provide a plan with a true unlimited data allowance for Jersey – every plan listed has a hard data cap, even those labelled “Unlimited.” Plans such as Jersey Unlimited 30 Days give 3 GB per day for 30 days, and O2 Unlimited (International) offers 35 GB for 30 days before speed is reduced.
Travelers who need a large amount of high‑speed data can choose from several fixed‑data options. For example, Jersey Unlimited 30 Days supplies 3 GB/day for 30 days at $112.40, while Bouygues Telecom 120 GB delivers 120 GB for 30 days at $42.47. These plans provide substantial data and are valid only for their stated period, allowing users to plan usage accordingly.
