The unlock of SIM is done.
Unlock of Galaxy A20’s SIM has been done!
Docomo’s smart phones are difficult and complicated to unlock.
I’m wondering what this device should be used for.
To install Ubuntu Touch in Galaxy A20 seems to be impossible.
I’ll try to install the latest Android OS, Droidian, postmarket OS, or Lineage OS.
CHIIKAWA’s stickers are on my mobile phone’s back.
