Any AOSP ROM would suffice.
The queation pertains to having a sense from how someone talks if they sound like they can configure network services or if they only read about it but not having the skills/experience to work for random customers and explain the work to them.
I think you’re mainly speaking from a place of percieved opinion than tech knowledge but I would suggest for you that you only use a landline for phone service. Have you ever had a job working with various network services for random customers and speak to customers to answer questions?
Why does a phone need to be in a ferriday bag when phone does not have a SIM card because it uses web-based VoIP service? The phone only needs an internet connection, like wi-fi, and can’t talk to cell towers. Remove SIM from phone, connect phone to wi-fi to get online to access phone service through the internet, GPS can’t function. If a phone without SIM calls 911, it will go through, but dispatch sees no number, no location, no name.
How can cell towers track your location if phone does not have a SIM due to using web-based VoIP service?
If you get a cell number with a SIM, then port that number to a VoIP, how does KYC matter since you are going.to have to give that number to people with your name, so businesses or offices can call you through VoIP service?
It is possible to get a real cell number from a big name carrier and then port the number to VoIP company to use VoIP service with an original cell number.
Switch phone service to VoIP, cancel cell service, all tracking capabilities is gone.
I know the SIM gets some information when the phine is turned on. I have never had data service on phone before, and I gave up cell service entirely awhile ago, so I was wonding how the iPhone could stay connected for service that has never existed or been used on phone.
Does that also work for people who never had data service and is a wi-fi only phone for calling, no cell/mobile service?
Your argument is purely ideological and reflection of your lack of experience travelling various countries that do not speak English. For example, go to a country where 100% of all business, companies, and offices, use Whatsapp because it’s the most stable form of phone service they have so they don’t have to pay for each phone call and pay for each text message.
Stick with only having a landline until you can get over yourself and your self aggrandizment.
