New SIM - says SIM currently being used with a device I don't recognise

[thisismyorange]

My iPhone was very recently stolen, I got an IMEI bar and lost/stolen bar applied, and ordered a new SIM, which I've now got (up and running) in my new iPhone.

However, if I look at Your SIM > Bar and divert > IMEI and PUK in Myo2, it says:

Device: Samsung Korea Galaxy S10+

This is the device that your sim’s currently being used with.

I believe this is a device used by a thief who must have inserted my (old) SIM to make a few international calls before I managed to block it and before I got my new SIM/phone.

Is this just an error with the system updating or should I be worried?

Thanks

The system can take a while to update with the correct data, so this isn't something to worry about, as only one sim card can be used at a time, and that is the one you currently have.

You can't have 2 sims with the same number as I said in your previous thread here https://community.o2.co.uk/t5/Pay-Monthly/Stolen-phone-barred-SIM-question/td-p/1616296 

As long as your sim is working with your number, that is all that is in use currently.

Thanks so much - just freaked me out seeing that unknown device seemingly linked to my o2 account!

Thank you!

Don't worry @thisismyorange 

Your sim is safe.
