Is it possible to put onstar's phone onto my ATT cellphone family plan? I know it will work with Verizon.

Nope. Onstar uses CDMA. AT&T uses GSM. The 2 technologies just aren't compatible. But you would think it could technically work with Sprint, but they won't do that. Sure it's a contract thing.

 

With Onstar, it's Verizon or nothin'.

Onstar uses AMPS (advanced mobile phone service which is an AT&T /Verizon conglomaration) as the primary carrier and CDMA as the secondary. However AT&T considers it to be two different services and will not allow you to share minutes. I have asked this question of AT&T and it seems to be a contractual agreement between Verizon, AT&T, and Onstar.

I pay an extra $10 per month on my verizon bill to have my truck as a second phone line. The minutes are shared between my truck and my handheld cell phone.

 

Just FYI.

I actually considered switching to Verizon/Onstar just for the hands-free phone service awhile ago. But Sprint lowered my bill even more and I didn't feel like paying the extra $$$ for Onstar minutes. But I'm sorta curious what Onstar is going to do when GM starts offering Bluetooth in all of their vehicles fairly soon. I don't see the non-Verizon customers sticking around just to pay $40 for 100 minutes + the monthly service fee. At the very least, they'd ditch the expensive phone package.

 

Perhaps they'll lower prices or "find a way" to open their network to other service providers ?

Can you give a little more details on this bluetooth adapter for the factory radio. I'm interested.

I know you can do that I said

 

However AT&T considers it to be two different services and will not allow you to share minutes. So where did I mess this up?

 

Best thing to do imho is to find out if the emergency button is still enabled once you cancel your service with Onstar or how do they shed themselves of the responsibility of calling for help if you have an airbag or emergency on the road then work around it, then buy an in car repeater for you current cell phone with a bluetooth portal that will allow your phone to connect while still on your side but allow you to talk to the remote microphone on the visor or in your ear.

I have a fully integrated bluetooth kit on mine (Navigation HU). It uses the GMX-320 lockpick along with the Raytel bluetooth kit to send video to the screen and audio over the factory radio. I'm not sure how the interface for the audio part works but the Onstar indicator on the radio comes on when I use the phone with this kit. Scoshe and Coastal are both supposed to have video kits coming out that are compatible with the GMX-320 and Nav radios like the Raytel kit. If you don't have Nav you can still use a Parrot (or other non-video output) bluetooth kit and have it hooked up to use the factory speakers but I don't know what other adaptors you might need to do this.

Ah, I see what you mean, I misunderstood your comment.

How do you go about activating the onstar phone. I already have verizon. Thanks

 

Just call Verizon and tell them what you want to do. They will hook you up.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
