Great question. If you’re in Austin, TX, you’ll install 2 new SIMs. The REALLY nationwide SIM as your first SIM, which will give you voice / text & data on the nation’s largest and fastest 5G network powered by T-Mobile®. Your 2nd SIM will give you access to the REALLY DeWi network in Austin, TX, which you’ll prioritize when available so that you get even faster speeds and better coverage. Depending on your device, you may be able to install eSIMs via a QR code.
