If you are a customer of T-Mobile,or AT&T you can upgrade phones without signing a new contract. My favorite way to shop for new phones is on eBay. I log on first to my cellular company's website to see what the latest and greatest is. Once I have an idea of the type of cellphone I want I look around on eBay for good deals. With over 220,000 listing's showing right now you are sure to find the deal that is right for you. Most phones sold on eBay are GSM phones which means if unlocked they will work with either network.
If you decide to use eBay for the purchase of your new mobile phone there are some things to consider. Try to find cellphones that are still in the box. Used cellular phones could have problems so its always better to just buy new. Make sure of the seller's feedback. I try to only buy cellphones from power seller's with a 95% or higher feedback rating. Read through the comments so you can make sure of the type of business a power seller conducts.
When a cellphone that uses a SIM card is unlocked any active SIM card placed in it will allow you to make calls. This feature is popular with customers who travel abroad and like to use a pay as you go SIM card from that country without the cost of buying a new cellphone. Countries overseas primarily use GSM for digital mobile phone service.
You can easily tell if a phone is unlocked by borrowing a SIM card from a different network. If you place the SIM in your phone and turn it on and the phone acts as if it belongs to your friend then the phone is unlocked. A cellphone that is unlocked will still show a logo from another provider if it was previously locked. However it will still allow you to place calls on another network and use any other capabilities it was designed for.
If the cost of paying for a new phone gives you the blues there is a bright side. In April 2010 Ymax the company responsible for the Magic Jack will be selling a new version that will essentially give you free outgoing and incoming calls on your cellphone. You must be within 3,000 sq. ft. of the device but, who doesn't like free?
