simpleSIM offers 15 single‑country plans and 5 multi‑country plans for the Isle of Man. The single‑country choices provide a range of data from 1 GB up to 50 GB, with prices spanning from $4.46 to $100.67 and validity from 1 to 60 days. The multi‑country options deliver similar data ranges—1 GB to 50 GB—within the same price spectrum, though they cover additional destinations beyond the Isle of Man.
If a plan is labeled a “daily data cap” it limits the amount of data that can be used each day, resetting the allowance at the beginning of every day of the validity period. A “fixed data cap” plan allows the total data amount to be used at any time during the validity period, without daily resets. Both types appear among the available single‑country and multi‑country options.
