View old iphone text messages on computer?

So there's a specific set of messages from October 2012 i want to read between my current boyfriend and I. He had an iphone and I had a regular non-smartphone type phone, so they were texts, not imessages. A few months back he switched mobile carriers and pawned his iPhone, so we don't have the phone, Is there any way to find the messages, using his apple ID or anything like that?

IF you have the sim card you can go on the website (Apple's) and make an account using your sim card

With the advent of the cell phone and the automated billing and payment systems most cellular providers permit, many cellular providers only provide an online glimpse of your cell phone usage and the usage of all phones under your top-level plan. Although most cellular providers don't record actual text messages, the majority will provide you, for a small fee, a print-out copy of dates and times text messages were sent.
instructions:
I. Visit your local cellular provider's main office and take along your individual cellular account information so the representative may bring up your information during your visit.
II. Provide your cellular representative with the precise dates for which you desire a printed copy of your account transcript.
III. Pay any fees requested of you by the cellular representative for the print-out and be sure to look at the top of the front page to ensure the transcript provided to you is in fact for your account and not someone else's.
