Change the APN settings on a samsung SGH A817

The simple answer is your settings are wrong, you can go to your carrier to fix it or a local repair shop.
The setting that is likely needed to be added or changed is called "apn" which is access point network.

If you feel comfortable with changing things in your phone; Go to settings > more.. > apn (if on screen) or mobile network > apn > menu button > Add or New > The next part will depend on the carrier you are on.

Yes, on an unlocked phone you can easily switch SIM cards. All you can do is put the T-Mobile SIM card in the phone and it should show signal bars on the top of the phone. If not you can call up T-Mobile and ask them for correct network settings and they should be able to help you out with this.

If the phone is not unlocked it wont work with any other sim card except the original carrier SIM card. In this case you first need to unlock it.
