Did you know that you can be instantly contactable on your usual number in over 100 countries world wide, when you travel with your GSM phone using your own number?
The major advantage of GSM technology is that it allows you to use your GSM phone when you travel outside your own country or region. This is known as roaming.
Roaming is the ability to use your own GSM phone number in another GSM network. You can roam to another region or country and use the services of any network operator in that region that has a roaming agreement with your GSM network operator in your home region/country.
A roaming agreement is a business agreement between two network operators to transfer items such as call charges and subscription information back and forth, as their subscribers roam into each other’s areas.
