Want To Know What Unlocked Cellphones Are?

If you have heard the term unlocked cellphone before and are wondering what exactly that means, then you have come to the right place.  Unlocked cellphones are phones that are free from being used on one carrier on their network.  What does this mean you might ask?  Well basically if a phone has been unlocked it allows the phone to be used on any network that uses a Subscriber Identification Module (SIM) Card.  The SIM card is a device that is provided to a customer by the service provider and is what allows the phone, the card is installed in, to function on their network.  When you have a locked phone it will only recognize the SIM card from the carrier the card came from.  With an unlocked cellphone it will recognize the SIM card from any carrier that uses a GSM network.       

Advantages of an Unlocked Cellphone

 There are some very good reasons why people prefer to have a cell phone that is not proprietary to a certain carrier.  It allows an individual to buy a phone that they like that their service provider does not offer and use it on their current phone plan.  The service providers feel that they must keep the phones they sale proprietary to their network because of the low cost of buying a phone when signing up for calling plan.  Without keeping the phones proprietary the carriers feel they will lose money.  This is not necessarily in the best interest of their customers as they don’t offer all the phones available on the market.  The second advantage is that it allows a customer to be free of a service contract.  They can purchase an unlocked phone and never have to resign a 1 or 2 year contract again.  The third advantage is that you can often times purchase phones that are not even available in the United States and you would be able to use it with your current calling plan as long as the phones band is supported by your carriers network. 

Disadvantages of an Unlocked Cellphone

There are some disadvantages to purchasing this type of phone.  The first being that they tend to be fairly costly.  In most cases you do end up paying almost the full price for the phone if you purchase one brand new, unlocked and ready to go.  If you don’t purchase one brand new there are two other options.  One being to ask your carrier to unlock your phone.  They might do this for a service fee, but this does not always mean your phone will have full functionality afterwords.  Some features of your cell phone make not work.  The second being to hack your phone.  There are many websites on the Internet that offer instructions on how to hack a mobile phone.  This tends to be a very risky option because if you don’t know what your doing you can fairly easily cause your phone to not operate any longer.  If you can get it to work properly this can be the cheapest option you have available to you.  The highest risk offers this highest reward in this situation. 

In the United States the only networks that operate on the GSM network are AT&T(formerly Cingular) and T-Mobile.  If you use either of these networks as your service provider then you have the option for an unlocked mobilephone.

    Hello, I am traveling to the Yucatan next month and due to family illness MUST be able to be contacted. I am told that if I unlock my prepaid cingular motorola it will work on the TelCel network in Mexico.
    Is this true? Thanks very much for any info!
