I am seeing much shorter data session times with Hologram since AT&T killed their GPRS support, leaving us with TMobile.

Here's a summary of the data session records from Hologram.

Looking at the past 20 days, I'm not seeing increased data use, but I'm also seeing much spottier reliability in terms of being able to connect to OVMS, even when the car is out of our metal-roofed garage.

I'm looking forward to the new hardware so I can get back to using AT&T.

Anybody else seeing anything like this?
