Aircards not Communicating US - AT&T Issue

AT&T has been progressively turning off 2G cell towers in the US on a regional basis as part of data migration to 3G.   If your GSM aircard was connecting primarily to an AT&T tower and does not have a T-Mobile tower nearby for good connection, you may be off-line at this time.   If you believe you are experiencing this issue, contact support@weathermatic.com or call our support desk for a resolution.
