Physical SIM not working after using eSIM abroad

Brian_Lee — Sun, 04 Jan 2026 02:56:39 GMT

I used a few eSIMs while travelling recently and when I returned to Canada, my physical SIM isn't working. I believe I may have accidentally “deleted” my primary, as I have no SIMs associated to a Primary on my iPhone. It says “No SIM”, but I believe the issue is with whatever I did by chance when trying to set multiple eSIMs.

Is there anything I can do to get my physical SIM to work properly?

hi @Brian_Lee

make sure you remove your travel esim, delete it

and then go to PM sim, enable Turn on this line and set it as Primary

you can then Reboot phone and Reset network settings

Thanks! Unfortunately I’m not seeing any option to turn on this line. I deleted my eSIMs, and when I go to Setting > Cellular, I just have a “Business” line with no number and when I try to set that as primary nothing happens.

hi @Brian_Lee

simply reboo the phone and reset network settings

if that does not work. Turn off the phone first. Remove the PM sim card. Turn it on for a minute. Turn it back off, put in the PM sim card, turn it on. then Reset network settings

Thanks so much! I’ll try that when I get home and have access to something to open my little slot for the SIM.

It does sound more like an iOS configuration issue than your physical SIM being “deleted,” especially after juggling a few travel eSIMs. I’d still follow the advice above: remove any leftover eSIMs, power off, eject/reinsert the physical SIM, then do a full network settings reset and reboot. Somewhere in the middle of all that, it helps to think like those carrier guides that keep an error solution page for SIM‑related glitches—step‑by‑step, change one thing at a time, then test again.
