What is Roaming

Roaming , also called roaming , is a term used in mobile telephony to refer to the service that allows users of an operator to remain connected to the network, even outside the location where they contracted the service.The roaming can be used nationally to regions with different area codes, or outside the country. Generally, charges for roaming services are higher than within the contracted coverage area.

How does roaming work ?

When a mobile phone user leaves the coverage area contracted with his operator, the network transfer takes place . This transfer can take place between the same operator or between different operators.

If the operator has coverage at the user’s location, it only transfers the signal from one antenna to another.

But if it does not have coverage in the region, it lends the infrastructure of another operator and, thus, keeps the services running. The roaming works for national and international transfers.

National roaming

The roaming national happens between the different regions of the country , defined by their DDD (direct dialing in the distance). If you leave the area of ​​the DDD where you contracted your service, you can remain connected while roaming .

This means that you can continue to receive and make calls and use the internet, but you will be able to pay additional fees for these services – these fees vary depending on operators and plans.

Roaming voice and roaming data

According to Anatel (National Telecommunications Agency), within the country, data roaming will not be charged if you are within your operator’s coverage area.

This means that the price for using the internet on your cell phone will be the same anywhere in Brazil – as long as your operator has coverage in that location.

In the case of calls it is different, as they will be more expensive whenever you are in another region. See how charges work in the event of commuting:

Case 1: You are in a different city than yours, but with the same area code.

If you make or receive calls, there will be no extra charge, the cost will be a local call.

Case 2: You are in a city with a different area code than your region.

  • If you receive a call, you will pay the travel fees – the person who pays for roaming is the person outside the coverage area.
  • If you make a call to an area code for the city where you are located, that call will be considered local and you will not pay extra fees for it.
  • If you make a call to your city or any other city with a different area code, you will pay travel fees.

International roaming

The roaming international is also possible. This means that you can leave this service activated on your cell phone and when you arrive in another country, with a different international direct dialing (DDI), you will be connected to the network of an operator that has a roaming agreement with yours.

In general, the costs for using international roaming are very high . If you need to use your cell phone for calls or the internet in another country, it is preferable to buy a local chip.

To avoid unplanned expenses, it is even recommended to check if the roaming option is enabled. If you do not want to use the service, simply disable the option in your phone’s settings.
