DEA

How would I set up with AT&T? (I assume that means OnStar uses the AT&T network, I didn't know that.) I let our service lapse after the initial trial because it didn't seem to be worth the $25 or per month, when everyone in the fam has cell data. (My T-Mobile cellphone hotspot is very slow, however (<1M) so not good enough to run a laptop. Very frustrating. Technology, my A$$!)
