Like I mentioned earlier, the average high speed internet bill is around $30. I know people who spend $14.95 or $19.95 a month on AT&T high speed DSL that is perfectly good for their internet needs. On the other hand, you can get Verizon high speed DSL at 54 mbps for $20.
One-day use by anyone (OnStar subscriber or not) costs $5 a day for 250MB. A 12 month, 10GB âbucketâ of 4G LTE service will cost $150 for OnStar subscribers or $200 for nonsubscribers. Existing AT&T customers can add GM vehicles to their Mobile Share plan for $10 a month.
