Can't access my second account

[Swift]

I have two contracts I can access my one phone but can't access the second one on three to check if it's due an upgrade, isit possible to have both contracts put on my three so I can manage them easier

Hello. 

You can have two numbers set up with 1 sign in on My3. To do that, you'll need to be the account holder for both numbers. If you head through to the Support Team and ask them to merge your numbers into 1 account, they'll be able to get that done for you.
