Sprint unlocked my phone but no data

[panxpany]

Hey there,
So I called sprint and told them I need them to unlock my phone for international travel and they did. I tested it with AT&T and it worked for phone connections but not for data. Any idea how to make ATT data connection to work?

APN settings?

So I need to enter specific APN settings for each sim card/carrier I use?

Depends on provider. On ting.com I did, now on byowireless it just works. Both resell T-Mobile.
Google for your carrier's apns settings, and add them.
