You cannot play without a time limit on online chess. If you want more time, you can choose when setting up a game, how many days you are allowed for each move. If you accept an open seek, you need to check how many days time limit there is before accepting, especially if you don't have a lot of time.
If you're talking about LIVE chess (games that you play in one sitting), then you can also choose how long you have. In live chess, you choose for each game, rather than each move. Chess.com does not offer un-timed games in live chess or correspondence chess as of yet.

Hello, I am new (2 games) to this venue. Never played online before.
I have now "lost" both on time. One game the opponent was 1 pt ahead, the other we were tied. How do you play without time restraints?
