Onstar phone

We use ours now and then and up till now, it was as good as a regular cell phone. However, they have switched carriers and gone from Verizon to Sprint, so I am anticipating that the service will go downhill quickly. We have NO Sprint service in most of the south Texas area where we work and very spotty service in both Idaho, our home and Nevada, where the family ranch headquarters is located.

OnStar systems installed after 2015 will be serviced by the AT&T 4G network but everything installed before 2015 will continue to be serviced by Verizon.

OnStar uses the cellular system. How does it work when cell service is not available? I had it on all three of my vehicles, but with Bluetooth I dropped OnStar and just use my cell phone.

OnStar uses a "high output amp" that is NOT available to you or I. I have heard 3W, but am not real sure. As long as there is "some" signal, even one you can't see, it will work.

Something like the old bag phones we had in the early years of cell phones. Thanks for responding.

I use it to call Canada and when I am in Canada. Verizon has Canada Calling but it is always a hassle to get that set up and then cancelled after a month.

I wish there was a keypad. I find it hard to make a call--it doesn't hear my voice very well.

OnStar IS Verizon in most of the US, Bell Mobility in Canada. They may fill in the gaps by roaming onto other CDMA networks.

OnStar Phone VS Verizon, in the US you are simply choosing to pay General Motors for Verizon voice service.

OnStar Phone thus cannot work where there is no cell service. However the phone in the car might work better than the phone in you hand, because its antenna is outside, not shielded by the metal shell of the vehicle.

If true that GM is switching carriers from Verizon to Sprint, expect bigger coverage gaps, depending on roaming arrangements.

My mistake, it isn't Sprint, but is AT&T that got the contract starting with the 2015 models. Seeing as how Verizon and AT&T technology is NOT compatible, I expect our OnStar system to go the same way as the older analog went, like the Dodo bird....

I use my OnStar occasionally when needing to make a call while driving. I purchase 100 minute blocks about every 12 months or so. I also get an email once a month from OnStar that provides a status report on the vehicle maintenance issues. Twice in the past 6 1/2 years I've had to call OnStar and have them unlock my truck when I locked the keys inside. I happy with the service.

There is a large area of NM where it does not work. I used it in WI when we were camping and did not have cell service. However, I had 360 min of time left and if you do not buy more time each year they cancel your previously paid for minutes. So they STOLE 360 minutes of my time and my money. I will not renew when the time is up. They are nothing more than a more powerful cell phone. They do not hook up to satilites like one may think.

OnStar can't roll over minutes if the cell company doesn't roll over. If you want roll over, contract with ATT. But even that plan has expiration at 12 months, limiting accumulation on roll over.
