what is the status of voip carriers and esim support on #linuxmobile?

theres fonus mobile which seems to be supported worldwide for a pretty good price. its voip, so will it interact with the same cell towers responsible for regular text/call? already talked to the rep, and they said only android/ios is supported, but im willing to bet that the rep doesnt care

also since sim cards are being phased out, how does esim support look on linux mobile rn? easy to use and transfer to diff devices?

@Logical_Error The eSIM support is handled by lpac. @z3ntu posted patches to lpac to make it work on QMI/QRTR modems and wrote lpa-gtk for a graphical interface.

I'm using my own custom service to set the SIM slot on every boot, and had to enable my eSIM from the command line. Otherwise, you can use your phone as if there's a regular SIM.

@flamingradian @z3ntu oh cool! i remember reading about https://lucaweiss.eu/post/2024-06-24-esim-manager-for-mobile-linux/ when it first came out but havent heard much since

there seems to have been no updates since then and no pmOS wiki page either about it so was curious if there were any updates regarding this

rereading that article, curious if QRTR can be simulated via software if an old qcom soc doesnt support a built in esim chip

@Logical_Error @flamingradian The eSIM support works on Qualcomm devices, so not sure what kind of update you're expecting.

Regarding postmarketOS wiki page, please feel free to write/update pages that need updating.

Your last question doesn't really make any sense, QRTR is the way to talk to the modem to send APDUs to the eSIM chip (eUICC) to enable/disable/install eSIMs. If there's no eUICC, you cannot talk to it. But there's eUICCs in nano SIM form factor that you can slot into the device.
