When you buy a local SIM card you are on one network only in this country. So if you buy Orange, you will be on Orange only, not on Bouygues. They are competitors on the French market. Only very few networks have "national roaming" like the "free" network in France and they charge you more for that. It`s different, when you have a non-French SIM roaming out of its home country. Then the operator has mostly contracts with many local networks for "international roaming" and the device can switch between them if you enable automatic network selection.
