SIM Card Registration & Activation Process for Tourists in United States

Tourists in the United States can purchase and use SIM cards without mandatory registration or ID verification, unlike many countries. Most prepaid SIM cards are sold over the counter at stores, kiosks, or online, and can be activated instantly without providing personal identification. However, certain carriers may request optional registration for service management or eSIM activation. While ID is not legally required, some retailers may ask for one as a precaution. This leniency reflects the U.S.’s more relaxed telecom regulation for prepaid users.
