iPhone 11 Pro Your SIM Sent you a message?

[oeagleo]

Okay, I'm trying to decide which setup I like better, and in the course of this, I switch the SIM from the iPhone 11 PRO to the Samsung Galaxy S20 Plus. My carrier (TracFone) doesn't register the EISN for their purpose, only the number on the SIM, so this is not only possible, but very convenient.
In the course of this, when I take the sim out of the Galaxy, and put it in the iPhone, I always get a message "Your SIM has sent you a message", with an (accept/cancel) option at the bottom. I've tried to see what this message is, but cannot find it in either Messenger, or the native iOS message app. Has anyone else seen this, or am I the only one who'd daft enough to try to decide between two phones?
TIA

There is a file on your phone called a carrier file that you do not have direct access to. It is used for configuration items set by a carrier. A lot of them are network specific. When a carrier needs to make an update to that file for whatever reason, they resend that carrier file to you phone. I would get that message a lot when I was on cricket without messing with my SIM. I've seen it once since I've changed to verizon. There is nothing you can do about it and it is not a sign of a problem with your device.

Since you get it every time you reinsert your SIM, it MAY be something else or the carrier may be updating the carrier file each time you insert a SIM.

Hope this helps.

Okay, that makes sense, perhaps it's just telling me that it's reestablishing contact with TracFone.. I can sleep comfortably now.. .
