Samsung galaxy s23 FE. My physical sim stopped working. Attempted to install esim, but that didn't work. Just visited a Currys to get a replacement physical sim. I've inserted it, logged in to ID account and, when prompted, typed in the new SIM number. I get an error message saying the sim is already activated. I've gone through the activate process several times and get the same message.

To install and activate an eSIM, you’ll need an active data or Wi-Fi connection. This could explain why it didn’t work for you.

 

If you’d prefer to get that replacement SIM activated as soon as possible, you can chat with a live chat agent using the link below.

I have an active wifi connection. How else would I have logged in to attempt to activate the sim, and place a question in the community?

Hi ​@celerman when you use the SIM, does it call with your number? The store may have got it activated already for you. Thanks.

You don’t need to log in to activate an eSIM; you simply scan a QR code, and the phone does the rest. For all I know, you’re posting here using a laptop or tablet. I was just pointing out that many people don’t realise they need an active internet connection to activate an eSIM and that’s why it fails and could be the reason why you had issues with yours prior to picking up a replacement physical SIM. I’m not sure why, but the activation process on THREE/iD is incredibly slow and clunky! It took me five minutes and a couple of reboots before my eSIM activated successfully.

 

As mentioned above, you can contact a live chat agent using the link above. They should be able to activate the physical SIM for you. Alternatively, you could wait for a reply from an iD Mobile employee, but this method may take a few days.

Once I got through the chatbot stage and got on to a real person, the issue should now be resolved. I had previously ordered an esim to try and resolve the original issue of my physical sim not working anymore. I was never able to activate the esim despite lots of support and attempts. Turns out you can't replace a physical sim if you have an esim awaiting activation. Hopefully, everything is sorted now. Just waiting for the activation to go through.
