International roaming is a service offered by mobile operators enabling you to use your mobile phone when abroad. All mobile operators in Malaysia, depending on your tariff package, provide international roaming. When you travel to a foreign country and your mobile phone keeps working that’s mean, you are roaming. You can make & receive mobile phone calls, write text messages (SMS) or surf the internet and download content.
Your calls, SMS and other data services are operated by a foreign network because your home provider does not normally operate in that country. For providing this service, the foreign network operator charges your home operator and your home operator passes this additional cost on to you. This is why some people having so called heart attach when receiving shocking expensive phone bills whenever they reach home

An email is normally between 1 and 50KB; a page of your favourite online newspaper can be 100KB or more. To download a song you would have to transfer 2 to 5MBs of data. Your operator will charge you a price that also includes the fee that the visited network charges the home operator to provide the service
Above 3 roaming activities might cost you a lot if you don't have proper roaming plan and packages and a wise precaution. Some might get shocked by thousand ringgit bill even they made only few minutes call from oversea. That's is why, Flexiroam is a wisest choice for frequent travellers especially those who gonna make and receive a number of calls who, in many cases are business travellers
Instead of making direct connection from oversea to Malaysia, Flexiroam acts as middle man and establish the connection between this two destinations. Thus, you just need to pay local call forward charge for example Digi to Digi while both of you in Malaysia. The fact that you're using international sim and making call and get charge as if you're in Malaysia isn't a joke. Yes, you transfer your call to Flexiroam and Flexiroam forward the call to your friend. Plus, he/she will get incoming call FROM YOU NUMBER instead of oversea.
You just need to pay flat rate RM10 perday! No more shocking bills :)
