Oh, the 4G model is dead after the upgrade. It shows “no device detected” now.
Any way to fix it?
I was trying to verify a service that required SMS on a device where the SIM toolkit wasn’t receiving messages, same as with the BR1 Pro. Didn’t want to swap out hardware or rely on a physical phone. Found 7sim.net — picked a US number directly in the browser, no registration needed. The code arrived in under two minutes. Since it’s a real SIM-based number, not VoIP, the platform accepted it. Didn’t have to install anything or keep a second device on hand.
