We recommend using the bonus JumpySIM card provided for the best cellular service in the US. Alternatively, choose a SIM from your preferred mobile carrier. Spacetalk suggests a cellular plan with unlimited talk and text and at least 1 GB of data.
JumpySIM plans include unlimited talk, text and data*, with roaming coverage to Canada and Mexico. JumpySIM plans start from just $18 a month. Note: JumpySIM plans are designed for Spacetalk devices. Using JumpySIM in other devices may result in limited service or cancellation. Please note, upon activation, JumpySIM incurs ongoing charges.
