The iPhone 4S is a CDMA and a GSM phone. You need to have an international plan activated for the sim to be active in our network. If you don't have an international plan the card is really just a piece of plastic and does not have provisioning/programming on it. If you plan on international travel you can contact international services at 888.226.7212, option 2 to have it activated.

Your answer is incorrect, imoddr.
Both Sprint and Verizon phones actually have SIM card slots. If you ask anyone who has a CDMA iPhone to show it to you, you'll find the slot in its usual place. They are there for those customers who travel overseas. Both Sprint and Verizon have international roaming plans for the iPhone. These would be pointless if the device didn't support GSM networks (as vast majority of mobile telephony overseas is on GSM).
In other words, every CDMA iPhone actually has two radios: CDMA and GSM. For GSM, radio, there is also a micro-SIM slot, together with a Sprint-issued micro-SIM card. Normally, this does nothing when within the US. However, once the phone is taken overseas, the GSM radio will discover a network and, if there is a roaming agreement, connect to it.
When Sprint first started selling iPhones, they didn't bother locking the micro-SIM slot, which allowed people to use micro-SIM card from ANY operator (including AT&T and T-Mobile). Later on, they begin locking the slot for the US-based GSM operators. I'm not sure, but I believe the slot is still unlocked for foreign micro-SIM cards.
I think Sprint is junk and I am going to move my service to another service that will serve me better because Sprint never able to help anything with their customers.. they should always put their customers first.. I just bought Sprint iphone 4 and trying to send over sea but when I look at it, there is no sim card which just ****** me off so bad. Thanks to Sprint I wasted another $$ to buying their products.
I'm very sorry to see that you feel this way, I assure you that we would hate to lose you. Unfortunately the iPhone 4 is not an international device, however we do have other device capable of international use. Have you looked into any of our other options to use overseas? Please let us know, we are here to help.

Awesome. That only took sprint 3 months to reply to. I like sprint. Never had an issue but I am quite upset I have an iPhone I paid for and it's basically worthless. A fancy iPod. What a [inappropriate word removed] we all took on the sprint iPhone.
