International Roaming Facility.

International roaming means whenever you are visiting another country with your mobile phone, you can receive incoming calls and you can dial any desired number just as calling from your home country. This is called roaming and it may bring you unexpected heavy bills.

International Roaming facility is available for the Sri Lanka people if they are taking their mobile phones with them abroad. This facility will allow them to receive calls to their mobile phones and also allow them to make calls to the phones of their relatives, friends and businesses from their own mobile phone very easily. But the charges may be little high as the service is coming through your service provider's partner. You are paying to your local mobile phone service provider and his foreign partner too.

The international roaming allows you to send and receive SMS text messages which will be also higher then your local rates.

The following mobile phone companies offer this service for Sri Lankans.
Airtel
Mobitel
Hutch
Dialog
Etisalat

If you have planned to travel a foreign country, contact your mobile phone service providers nearest office and ask them about the tariff (call charges). Roaming from some countries may be giving you heavy phone bill. Not only for the calls you may make but also for the incoming calls you will be charged.

If you are having a smartphone with 3G service option be careful, as your smartphone may try to check for your emails for every 15 minutes and because of this you may run in to heavy mobile phone bill, when you reach home. The bill may be mostly for the internet connectivity charges through the roaming partner.

Also some packages need to be activated by the service provider for international roaming.
