Next time be careful what you buy and from where you buy it and the status of the product. As I understand it iPhones lock themselves to the first network on the first SIM card inserted and stay that way. Apple make unlocking difficult to prevent and deter theft. And they generally only allow the original purchaser to make changes
The other consideration is that the activation lock may still be on. If so you would have to contact the previous owner to get him to go to iCloud and log in to his account to erase the iPhone and remove it from his account.
“As I understand it iPhones lock themselves to the first network on the first SIM card inserted and stay that way.“ I believe this is true only if you buy the iPhone from a network provider. If you but the iPhone directly from Apple is does not become locked to any network. I have always bought my iPhones unlocked directly from Apple and used them with various networks worldwide.

It's possible to get it unlocked by iD, just depends on whether it is in contract or not.
Son bought a 2nd hand phone, was locked to iD (was very cheap!) we contacted iD via there website, they checked the phone IMEI, reported it out of contract, and sent us the unlock code free, took a couple of days, but one happy son. Think their i-phones are slightly different, but check out this from their website.
