activate my phone

To activate with Wi-Fi, you'll need:

• Your iPhone
• A Wi-Fi network (or a cellular network for iPhone 4S)

Simply hold the On/Off button and follow the onscreen instructions. If you don't have access to a Wi-Fi network, you can activate with the latest version of iTunes.

To activate with iTunes, you'll need:

• Your iPhone
• The latest version of iTunes - Download
• Your Apple ID - What is an Apple ID?

Just connect to your computer and iTunes will guide you through activation, as well as sync your music, video, bookmarks, and contacts.

You will need to have a SIM card to connect to the carriers network. Contact you're carrier to have a replacement SIM sent out to you.

Yes

Yes, you can go to the store and have them give you a sim card with your plan. I hope you paused the cell service when the phone was stolen, otherwise the thieves may be using your data and costing you more money.
