OnStar requires update due to 3G end of life

I was wondering if anybody has had the update to their TV to handle 4G? My Silverado required a hardware change from 2G to 3G but apparently the change to 4G is "over the air". Haven't driven the truck in the last two years but I'm thinking about it now.

My 2015.5 Denali came with 4G, no need to have the over the air update. but different models had different switchover dates to 4G

My understanding is that if the vehicle needs the "over the air update" to 4g it should be transparent to the user, and likely has already happened.

If it needs an over the air update to use 4g I hope it happened last week before 3g went away!

ALL 3G is not gone. I think it was just ATT.

Google: T-Mobile announced that it will finish shutting down Sprint's 3G CDMA network by March 31, 2022 and Sprint's 4G LTE network by June 30, 2022.

Time to go for a drive.

I think Verizon is December. I had one 3g device and they notified me that it would have to be replaced by sometime in December so I assume it is for all uses of 3g. Not sure if all 3g OnStar like systems can be upgraded. A friend said his car that was less than 2 years old wasn't upgradable. But then maybe he just wanted an excuse to trade up without the wife discussion :-)

Both my phones need replacement.

Mobily owners report no issues with the 3g dying on Feb 22, 2022

ALL, REPEAT ALL 3G is going away ATT first, others a few months later or some already. It went away in Canada a few years ago. Last of Verizon will be shut down by end of December 2022

And for the last few years there were lots of places that 3G transmitters were shut down, coverage is sporatic.

Perhaps I should have said: I'm in Canada and 3G isn't going away until 2025. I only use the truck in USA but I can get an over the air update here before I cross the border.

My Silverado is 2011 - built before 4G went into service here - it came from the factory with 2G. The truck is old in years but it only has 110,000km (~65,000 miles) after 11 years - it's just broken in.

I just wondered if anybody here has gone through the process.

Hi ktmrfs,

3g for data disappeared--but for voice, it is alive and well in Canada.

Probably would have but I haven't snowbirded for two years. The truck has essentially not been driven for two years and I turned off Onstar when I thought I wasn't going to drive the truck for one year. Who knew....

OnStar is satellite, turn by turn traffic avoidance is via cell tower. I understand OnStar will make the updates needed via satellite. Most things other than up to date traffic will not be affected.
