CNET'S QUICK GUIDE: Unlocked phones

How can I get an unlocked cell phone?

If you think an unlocked cell phone sounds like a great idea you'll be pleased to know that new unlocked handsets aren't difficult to find. Just remember that since carriers sell only locked handsets, you won't be able to pop into your local AT&T store for unlocked models. Instead, you'll have to shop in independent cellular store, or you can look online. But keep in mind that because you're not getting any carrier rebates, you will pay full price for most unlocked models. Higher-end phones such as the Nokia N95 can run you as much as $700.


In stores
Though you won't find an unlocked phone in a carrier store, they are widely available in retail locations run by a third party. It may be difficult to determine whether a store is affiliated with a carrier, so it's easiest to just ask if they sell unlocked models. Also, an unlocked phone can make a nice souvenir from a trip to Europe and Asia. Since unlocked models are more common in those regions, it's easy to find a wide selection.

Online
Unlocked phones are widely available form online retailers. Just pick out the model you like, then click the Purchase button. You also can buy unlocked phones on eBay or other auction sites. But be careful with what you buy online, particularly from anonymous sellers.

What about a SIM card?
If you have an unlocked phone and need service you sign up with a GSM carrier as normal. Just tell them you'll be using your own phone and that you only need a SIM card. Carriers love new customers so you shouldn't have a problem. But if a customer service rep tells you (incorrectly) that using an unlocked phone is not allowed, then try another carrier store. Or better yet, sign up on the service provider's Web site.

Can I unlock a phone purchased from my carrier?
The good news is that you can unlock a GSM handset--all you need is an unlock code. The bad news is that it's a bit more complicated than just flipping a switch. Also, it's important to note that not all functions will work right away. See the next page for details. Here are the most common methods.

Get it from your carrier
Believe it or not, carriers will unlock phones for you. It all just depends on who and how you ask. As far as we can see, no carrier has a set policy; it all just depends on the circumstances. You may get a nice customer service rep who is willing to give you the code or you may talk to a more strict one who's not so cooperative. One good piece of advice is that if you're off your contract, they'll be much more likely to do you the favor. And if you're successful at getting the code, you may have to pay a fee.

Try online
Unlock codes are available form online sources, sometimes for a fee. CNET's Download.com has a selection of options.

Other sources
Independent gadget shops can also unlock a phone, but we can't make any recommendations. Again, we can only say caveat emptor.
