USA eSIM provides a range of unlimited data plans for the United States of America, covering both 4G and 5G networks. Plans start at $3.50 for a 1‑day validity and extend to $90.00 for a 90‑day period, offering flexibility for short‑term travelers or longer stays. While the data allowance is unlimited, speeds may be throttled after heavy usage in accordance with a Fair Usage Policy, and tethering is permitted on all plans. If avoiding potential speed restrictions is important, travelers should contact USA eSIM to confirm the details of the FUP and expected speed limits for their specific use case.
