Hi,
Anyone have any idea how can I swap SIM card in EU/UK model3.
In the service manual shown the Simcard slot location is under the MCU computer over passenger footwell.
Unfortunately after Tesla rollouts autopilot hw3.0 the slot is no longer there.

But usually the European model S/X have external SIM card module easy to access. I suspect model3 would have the same thing.
the reason I am switching the SIM card is to get LTE connectivity in my city I am a grey market customer outside Tesla core market.
I would be greatly appreciated for any suggestions
thank you.
Brian

That right angle connector looks like a high speed coax RF connector, not a digital connector one would use for the serial connection to the sim card...I hope they don't want the computer removed to get access to the sim card!

From my observation Model S/X external sim module also used the similar HSD connector.

Here are few pictures from my Model 3 (Europe, VIN 376xxx).
It is definitely HW2.5 (as written on one of the labels), and similarly does not contain SIM card slot and does have that additional green coax connector.

Thank you for take the metal flap cover out. They must moved the sim card module somewhere or is it an eSIM on newer cars?
I just found out that the green connector is a emergency call antenna.

I would assume they are now at using e-sim´s This far more easy and can be changed via software and remotely changed as well. T-Mobil is one of the first telecom companies using it (e-sim) here in Europe and makes in my opinion more sense anyway.

Given there's much of interest on SIM replacement topic here in Ukraine, fellow Tesla owners were able to confirm with Tesla that:
- Model 3 indeed uses eSIM now
- Physical SIM slot is still there
- Physical SIM can be inserted and used, but that may require Tesla service assistance to activate.

Someone over in Russia got a hold of a US spec Model 3 with the -NA Telit LTE Connectivity board and posted info on replacing the eSIM (if needed)
with a regular SIM from a local telco. Source www.drive2.ru, rough Google Translate robo-translation follows:

"Found how simple and cheap to solve the problem. I share: de-solder the eSIM chip and instead of it solder in an extension cord with a SIM card slot (online for $1).
Insert a regular activated SIM card and everything works. The whole procedure takes 30 minutes.
I’ll lay out the whole process separately."

I'm confused.

I thought hardware 3.0 was only the autopilot computer. Why would the SIM be part of that?
Are you sure you have the correct component?

I took it myself but nothing happens after fully inserted the sim card.
As far as I know (from people who actually replaced the SIM card in their car), Tesla service still needs to reconfigure car software to use physical SIM instead of built-in eSIM.

Hello guys, just bought a m3.
I am living in Morocco and need to activate the physical SIM card since the esim is not activated in Morocco.

i have tried to insert the physical one in the HW3 , but nothing changed ? Do you have an operation mode to make it activated ? Thanks for your help
