ByteSIM does not provide a truly unlimited high‑speed data eSIM for the Isle of Man. Its “Unlimited Data” plans actually give 1GB of high‑speed data each day, and once that daily cap is reached the speed drops to 10240kbps. The plans range from 1 day up to 30 days, all with the same daily 1GB allowance.
Travelers who need more data without daily throttling can choose one of ByteSIM’s fixed‑data options. For example, the 50GB for 30 days plan costs $54.90 USD and the 20GB for 30 days plan costs $25.90 USD. These plans provide larger data allowances that may be more cost‑effective for heavy data users.
