SeferESIM does not provide a truly unlimited data eSIM for the United States of America. The plans titled “Unlimited” actually offer 1GB per day of high‑speed data for a fixed period—7 days or 30 days—and after the daily limit is reached the speed is reduced to 512 kbps. For travelers who need larger amounts of unrestricted data, SeferESIM offers fixed data plans such as a 100GB bundle valid for 10 days or a 50GB bundle valid for 30 days. These fixed plans keep high‑speed 5G access for the entire validity period and can be more cost‑effective for users who consume large volumes of data.
SeferESIM does not offer United States of America eSIM plans that include a phone number or SMS capability; only data‑only eSIM plans are available for that destination.
Travelers who need to make calls and send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. Some destinations, however, may block or restrict certain VoIP services, so it is advisable to check that the apps you rely on are accessible in United States of America before purchasing a plan.
SeferESIM currently offers 75 single‑country data plans and 92 multi‑country data plans for the United States of America. The single‑country options cover a mix of fixed data‑cap plans, which provide a set amount of data for the entire validity period, and daily data‑cap plans, which allow a daily quota that replenishes each day. The multi‑country plans similarly include both fixed and daily data options, but with coverage that extends beyond a single nation. In general, the plans range from about $0.60 to $703.56 in price, while data caps vary from 100 MB up to 100 GB, giving travellers a broad spectrum of choices that cater to short trips, daily usage limits, or longer‑term stays.
