This morning a funny thing happened. I had previoiusly configured my Cosmo to use an esim but when I opened it to use it outside the wifi coverage the first time I found I had no cell bar or 4G indicator. esim was still enabled in cosmo settings but I went to the esim wallet and it was empty - no error, just my esim had gone.
I got the activation code again and scanned it but the wallet crashed which I remembered from my first attempt seemed to mean that it could not communicate with the chip.
I used the Save and Exit button which disabled the chip, then I reenabled. Still no sim. Repeated the process and the sim returned.
I noted that after the sim was displayed, I no longer had the save and exit button.
I will try to see what causes it to lose the SIM. I had replaced the SD card and launcher as well as done several restarts without paying much attention as wifi was working.
