What Is The History Behind Unlocked Cell Phones?

An unlocked cell phone is a phone that will recognize any SIM card

. When you buy a cell phone from a provider the phone is locked to the providers network. Even though the phone may be compatible with other networks, it cannot be used on another network as long as it is locked. However, more cell phone businesses are catering to the unlocked cell phone market. Unlocked cell phones can be used on any GSM network with interchangeable SIM cards. Normally, the unlocked phones that are sold by online sellers have been unlocked using special software.

When a cell phone is purchased on a carriers service plan, the SIM card in the phone is linked to the subscriber's personal information for billing. Most carriers lock the phone by programming the software so that it will only work with their SIM card. At one time, unlocked phones were only available in certain markets where people bought cell phones from overseas. A person traveling in Europe would buy the unlocked cell phone to prevent incurring roaming charges, or have every local call billed as long distance by the North American cell phone carrier. They would just purchase the local European carrier's card and inserted it into the phone. Recently, more manufacturers have started making unlocked cell phones available in North America and are selling them in their stores and on their websites.

Cellular providers all over the globe, including carriers based in the US and Canada, rely on GSM technology for their networks. GSM phones come with a slot for a SIM card. When unlocked, you can replace the carrier provided SIM card to allow you to use the phone on another GSM network. Unlocking the phone has many benefits. You do not have to buy a new phone and can take your data with you. It is helpful when you travel and switch between carriers as you can use the same phone, instead of multiple phones and accessories. You may also be able to save money through your carrier of choice rather than the manufacturers.

If a cell phone is unlocked, it can recognize any SIM card, in spite of which cellular service provider issued it. The most popular reason why consumers will acquire an unlocked cell phone is to increase their options when it comes to selecting a new cell phone service provider. The other reason why people will get an unlocked cell phone is to keep their current cell phone when they switch to a new cellular service provider. If you are considering unlocking a GSM cell phone, the provider will normally unlock the phone for a fee. You can contact the network provider to find out if unlocking the cell phone must be done in person at the store. Many people who are frequent international travelers are buying unlocked phones as they benefit the most from using these devices. There are more options available now than ever before, so make sure you are educated and do your research to find the best deal.
