Hello MI Fans,
Hope you were enjoying this Summer!!!
  • When we were talking about Roaming it always comes to our mind that using two mobiles in different countries.
In this tech class, we will discuss Roaming in details. So, Let's start.

To work of Roaming smoothly, there are two things appropriately involved, the Mobile and the carrier.
The Phone is the fundamental need to use roaming service by connecting to the network, and the device should be compatible with the carrier to provide roaming services.
In other words, CDMA carrier devices may not connect to the GSM and all GSM networks will not work under the same band. So all GSM handsets cant be used anywhere in the earth.
But be sure that upgrading to 4G service does not mean that not all LTE handsets will have 4G LTE coverage wherever LTE support is available.
To use the roaming service you need two carriers to make roaming work, your home carrier, and the visited carrier.

Calls and Messages on roaming
In many locations, there are cellular phone systems operated by more than one carrier. A cell phone will connect to whichever tower offers the strongest signal.
  • If the service from that tower is provided by the same company which provides the cell phone, the connection is said to be ‘on-network’.
  • If the cell phone connects to a tower providing service by some other company, the connection is said to be in ‘roaming’ mode.

What you need to check before you visit abroad.
  • First of all, you need to check whether your service provider that your mobile subscription allows you to use your phone in another country.
  • You should check the operator have a roaming agreement with any network in the country you are visited.

How mobile will work outside the home country?
  • When someone visited another country, your operator does not have any coverage but you are still able to get call messages, and this happens only because of the home operator has a 'roaming agreement' with an operator in the visited country that enables you to use its network.
  • When your device will device connects to the operator it will authenticate your mobile phone with your home operator; If everything looks good, then your mobile phone is ready for use.
When do I want to make a call when roaming, what happens?
  • When you are roaming, and you are trying to make a call, the operator in the country will analyse the dialled number and decides the best route the request.
  • If you are calling back to the home country, then the visited operator will connect the call back to your home country.

How will you receive a call?
  • When someone calls you on your mobile, the call will usually be routed to your home country and your home operator. Your home operator knows where you are roaming.
  • And will then forward the call to the operator whose network you are using in the visited country. The visited network will then connect the call to you.

How can the billing be done when you are on roaming?
  • While you are on roaming the operator of that country where you have visited will record your call and send them, along with the corresponding charges. All these will reflect within your next bill.
Data on Roaming
Data roaming is same as you are using Call and messages in the roaming network. There are also some common services that will be counted as data roaming, and These are like :
  • Searching for an address on Google Maps
  • A web search
  • Visiting any web page
  • Watching videos online
  • Opening an app that connects to the Internet

Xiaomi introduced an app called Mi Roaming which allows using the roaming service across the world which out purchasing any new SIM card. You can enjoy it by paying some amount mentioned by Xiaomi.
The function can only be activated once you reach your destination. Activation will fail if you are not at your destination. After activation, billing will start. It will take some time to connect to the local service provider after activation.
Speed is limited when you exceed a specified data usage limit.

Hope you will get knowledge about Roaming and how it works

Thanks to being here.
