You can use the SIM out of the MCU in other applications.

So I part out Tesla cars and recently one of the screens was damaged. I decided to see if the SIM would work outside of the MCU. I purchased a modem off of Amazon that can support a SIM. The modem arrived and I plugged the SIM in and it works great. A whopping 12 Mbps though but not bad. The next test is to see if there is a data limit or throttling.

I am surprised they are not locked to an IMEI list or range

Yeah I was not expecting it to work. I heard someone trying to use it in a cell phone but had no luck.

With a nice view of the SIM card number it wont be long before it stops working.

That's the SIM type I believe.

Interesting
Would that also mean that a similar Sim from ATT with a fast data plan would work in the MCU?
Somehow I doubt it.

Probably. The device may be SIM locked, but that is usually by carrier, and I think Tesla uses AT&T anyway, if I recall.

My Audi used AT&T, but I swapped in a T-Mobile SIM for faster data and a cheaper plan. The device was not SIM-locked, so it worked with any carrier on compatible bands. Unlike Tesla, the SIM slot was easily accessible. It's a moot point though for legacy owners - since we don't pay for data, there's no motivation to change carriers unless AT&T is particularly horrible in your area.

Bingo, it's ATT.

I haven't pulled apart an MCU yet, but is the SIM easy to access?

You have to take the screen apart but it's fairly simple.

Do you know what data plans cost for non-legacy?

I don't pay anything but I am 2nd on a 2017. Not sure if it is different for older model years.

And I am 2nd on a 2013. Same. No pay. And happy as a Lark too!

According to this:

Frequently Asked Questions - Connectivity

How much do Standard Connectivity and Premium Connectivity cost?
There is no fee for Standard Connectivity. Pricing for Premium Connectivity will be announced soon, which we expect to be approximately $100 (USD) per year.

MCUs are not sim locked too. I'm using my country's carrier sim in my MS.

Did you swap the SIM yourself?
Did you have to reconfigure software to use your SIM?

 

[iamhtoo]

Did it myself. No need any reconfiguration.
