I just learned about the Volla 22 phone and starting to do the research on this. I reside in the USA and my carrier is AT&T and have been an Apple iPhone user for 20 years.

Is the Volla 22 a plug and play for USA users? Or will it require configuring it with my AT&T carrier? I don't care for the apps like most users like and enjoy. I want a good phone which has privacy and security in mind. Any information one preferably in the USA can provide will surely benefit in making my decision if this phone is right for me. I do have a Linux Mint Debian Edition OS on my desktop and laptop with limited terminal command skills. What is the time once an order is placed and paid for before the phone is received?
As stated any information provided negative or positive would be appreciated. Thank you very much and very pleased to be a member of this community.
