Change WiFi carrier on 2021 yukon

[Jon rogers]

Anyone know where the SIM card is for the factory att WiFi? I want to change it to t-mobile. Much cheaper

It’s a built in Esim, or at least it was in my 2020 truck. You’re married to AT&T for life. GM and ATT have an exclusive contract is what I was told.

I was paying $25 for an unlimited plan on my own ATT account (not through OnStar).

I have Google Project FI (basically TMobile sold through Google) so I put a router with one of my data only sim cards in the glove box. You could probably do the same.

Not sure how much T-Mobile's connected car service costs, but you find that AT&T ends up being your only option, you could potentially negotiate the monthly price down if you're an AT&T subscriber of any of their services. I'm already an AT&T subscriber for my personal and work phones, and TV streaming service, so I used that to negotiate a lower monthly for in-car wifi service (unlimited data plan, 25% discount).

We went with the AT&T option. was cheap enough doing the longer prepay vs some of the others... but you could find one of the older "free" tmobile hotspots on ebay for $20 last time i checked. and as someone else mentioned put it in the console or something

Also, if you are an AT&T mobile customer you can add your vehicle for $10.00/mo as another shared device on your plan. I have a chevy, jeep, and ram on my plan. You can do the vehicle adds either through AT&T or OnStar in the GM vehicle case. They will coordinate with each other. You need to know your AT&T pin code.

I use a hotpsot in my truck with tmobile, it's powered by usb you can get a hardwired 12v to 5v usb adapter and hide it anywhere, some hook & loop fastener and it can be hidden under the dash and take no space at all. out of sight out of mind. If you have a tmobile data plan already you can just put the sim in and go there like $40 on ebay
the linkzone has pretty good reviews I have had mine running 24/7 for over 2 years I think I had to reboot it maybe twice, from the center console the signal will reach about 40 feet or so.

I saw a post on a Bolt forum where they soldered a SIM socket to the communication box, and also change some micro resistances to different positions

The diagram on the Tahoe would be different no doubt so the resistors position won't be the same, but its a start!
