It is somewhat useless because there is a good chance that your mobile phone's IMEI has your name attached to it in some database.
Most countries now record owner details when you buy a new phone.
If you want to make anonymous phone calls, I suggest creating a skype account and funding it with gift cards, and use a VPN to conceal your IP.
Tip: use a VPN location close to︀ you, or there will be delays / bad quality when calling.
In terms of VPN,︁ if you are tech-savy, run your own VPN and pay for your server via crypto.︂
There are quite a few server providers out there who accept crypto.
Easy run your︃ own VPN Solution: Enterprise VPN Server
For a safe VPN, I would recommend PIA︄ (Private Internet Access). You can pay with crypto and give fake name/details for your account.︅

Regarding Data Protection:︆
I need a bit more context, to give you a tailored solution
f you're worried︇ about being raided by the authorities and want a single-click button to lock all your︈ drives or something like that?
But for general data safe keeping, I recommend having your︉ data encrypted.
Windows: Turn on bitlocker, do not use microsoft account to unlock the drive.︊ Instead, store the encryption key in a safe place.
Mac: Turn on File Vault, do︋ not use iCloud to unlock the drive; instead, store the keys in a safe place.︌
Cloud Storage encryption: Boxcryptor Security for Your Cloud
^ This acts as an additional layer︍ of encryption on top of Google drive or Dropbox. So even if anyone gets access,︎ they need your encryption key to view the files.
Private internet access has a dedicated IP solution︀ to your VPN location of choice. (Extra add-on feature)
No one else will be using︁ the IP besides you.

In terms of detection, streaming sites like Netflix or Amazon prime will detect your right︃ away but you will have no issues with Paypal or any other website.
