Dual SIM Phone

I have a Dual SIM phone. Therefore has 2 phone numbers. One number is on Sky (Virgin O2) other is on Lebara (Vodaphone)  -

  1. How best to install? 
  2. Is each SIM (phone number) treated as a seperate device? (Laptop + dual SIM phone = 3 devices?) 
  3. I have several email accounts Work (NHS.net) + pivate, community group, charity volunteer account = all Google  - are these treated as seperate devices? (3 devices with 4 email accounts on each) NB: All accounts are on the phone and the laptop. Is subscription each account acoss ALL devices? OR - Per device - all Google/email etc accounts?

Thank you. 

1.  Installing Norton on your device is not tied to any phone numbers. So you would just download and install normally from your Norton Account.

2.  As noted above, it is just one device and would only take up one activation from your subscription.

3.  The only email account that matters to a Norton installation is the email account associated with your Norton Account. From that email you can install to as many devices as you are allowed on your subscription. Accessing other email accounts on each of you devices does not affect your Norton Account.
