Modem can't dial out

[wibble]

then why is this phone shipped with this dysfunctional pmos???!!!

None of the OSes are fully functional yet, and they're all moving quite quickly. This means that whatever OS they picked to ship would be outdated by the time it arrived. It's only meant as a starter so you don't have to use an SD card to boot the first time.

I wish Pine64 would make it more obvious what the software state is in the product descriptions, as well as making the separation between them making the hardware, and the software being a community effort. Some people seem to be buying it expecting a fully working phone out of the box, while a bit of reading in the forum should show that's not a realistic expectation.
