US Mobile 30-Day Free Trial: 30GB Data for Port-Ins

US Mobile currently gives eligible new customers a 30-day free trial when they transfer an existing phone number to its Warp or Dark Star networks. The official offer includes 30 GB of data for the full trial, unlimited talk and text, and 5 GB of hotspot data. This is a port-in offer: customers taking a brand-new number instead are directed to a separate paid introductory promotion. US Mobile requires a valid credit card to create the account and activate the free trial, and AutoPay must remain enabled during the 30 days. Trial lines are set to renew on Unlimited Premium unless the customer changes the plan or turns off AutoPay before the promotional period ends. The offer is limited to one eligible line per new customer, cannot be combined with other introductory promotions, and prior US Mobile device/number usage can affect eligibility.
