What is RedEx?
What is RedEx?
RedEx is a travel eSIM provider operated by Autosense Inc that allows purchasing and activating data and sometimes voice plans without a physical SIM card. The eSIM is digitally installed on a compatible device via a QR code or directly from the app, then connects to the local partner network upon arrival in the country. RedEx offers local, regional, and global plans mainly focused on data, with prepaid formulas of various durations and volumes. Some plans combine voice and data, with coverage announced in over 207 countries and regions and operation on 4G and 5G networks depending on local availability. The RedEx app for iOS and Android allows buying, installing, and managing eSIMs, tracking usage, and topping up a plan when data volume is almost used up. The service also highlights the ability to keep the main SIM active to continue receiving your usual number and bank verification codes while using RedEx data.
