Monitoring

AT&T’s announced 2G/3G Shutdown is occurring on Tuesday, 2/22/22.

Particle 2G/3G devices in the United States with available T-Mobile service are expected to connect via T-Mobile (until T-Mobile completes its own 2G/3G sunset - see the link below for more information). US 2G/3G devices dependent on AT&T coverage only will no longer be able to connect.
