Prepaid Global Roaming Sim Card
In order to understand, let us look into the GSM classifications very briefly.
Global System for Mobile Communications (GSM), is a world leading standard, first adopted in Europe and then spread through Asia, Africa and Australia, New Zealand, etc. GSM coverage maps are available for nearly all courtiers. It is a digital technology and uses Time Division Multiplexing methods in communication. There are three categories of GSM phones that are available:
The dual band GSM phones operate on 900MHz or 1800MHz. These phones will not work with the service providers operating on 850MHz.
The tri-band phones have operating frequencies of 900MHz, 1800MHz and 1900MHz bands. These phones will work around the world including North America, but will not work in places where the service providers support only 850MHz.
The quad band phones, on the other hand, operates on 850MHz, 900MHz, 1800MHz, and 1900MHZ and therefore would work every where around the world with all the service providers.
Therefore, for your international travel, it is necessary that your GSM mobile is a quad band handset for it to work world-wide. Or else, it should atleast support tri-band frequency ranges. If you do not own such a phone, you can always rent one for your travel abroad. Please visit www.planetomni.com/RENT_INFO.shtml for more details.
A pre-paid SIM card activates your GSM mobile, without you having to enter into any contract with the service provider. It already has airtime credit included in it, when you purchase such a card. When you have reached the limit of your airtime credit, you may re-charge the card with re-charge vouchers, to extend your credit. The SIM card has a life expectancy of 6 months, after which a you need to purchase a new SIM card. With some service providers, this life expectancy of the SIM card can be increased indefinitely by keeping on recharging the card for your airtime credits.
With the pre-paid global SIM card, you get the benefit of having the same number, which you can carry through your journey in different parts of the world. On top of that, the calls that you receive are free of cost, no matter where it is generated from. You save on the charges that you would need to pay for roaming, which you have incurred, if you would take your usual mobile with you. Further, it is doubtful whether your phone would work in the countries you visit, if you do not have a quad band handset. In this scenario, imagine the charges that you would pay to call your business associates or your family at home, from your hotel room. A pre-paid global roaming SIM card has that much saving for you.

These SIM cards can be re-charged for new airtime credits when-ever you need it. There are many countries, where the service providers allow incoming calls even if you have used up all your airtime credits, which become an important feature with these prepaid SIM cards.
