No, 4S eSIM does not provide truly unlimited high‑speed data options for North America. Every plan listed under the “Unlimited” label has a concrete data cap—ranging from 3GB to 50GB over the validity period. Once the cap is reached, the plan’s speed drops to a reduced rate of 1000kbps.
Travelers looking for large data allocations can choose one of the fixed‑data plans available, such as the 50GB Unlimited 5‑Day plan priced at $68.42 USD or the 30GB Unlimited 15‑Day plan at $83.87 USD. These options offer a substantial amount of high‑speed data before the throttled speed applies, which can be more economical for most users unless extremely high data usage is anticipated.
4S eSIM does not offer any North America eSIM plan with a phone number or SMS capability. The provider sells only data‑only eSIMs for the region. Travelers who need voice or text services can generally use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to check the availability of the desired services before purchasing a plan.
The Global plan includes Canada, Mexico and the United States of America as its North American coverage, and the North America plan is dedicated to the same three countries: Canada, Mexico and the United States of America.
