Checking communication area

When choosing a SIM card in the United States , check the area that covers the vast territory of the country. Ideally , you should choose a SIM card that provides stable communication not only in urban areas but also in rural areas. If you are traveling to multiple countries, it is convenient to have a SIM card that can be used in other countries.  

Data volume and speed

In the United States, 5G is being rolled out, especially in major cities, and 4G is also widely covered. Choose the appropriate data amount and speed according to your travel schedule and usage. If you plan to upload videos or download large amounts of data, we recommend a large-capacity data plan.  

Rate plan

Choose the most cost-effective plan based on the length of your stay in the U.S. and your data usage. A daily plan is often better for short trips, while a monthly plan is better for long stays or multiple uses.
