VoLTE & iRoaming


Data roaming is using the Internet on your phone when you’re abroad, whether it’s browsing the web or sending an email. Smart phones are permanently connected to the Internet so you could use data without realizing it. However, it is pricey, we suggest you turn it off when you`re abroad.

1. Go to Settings>(Dual cards and) Mobile network, click iRoaming to download & install this app;

2. Enter iRoaming, select and purchase the data network service you need before going abroad;

3. After going abroad, go to iRoaming>Order, touch Activate to activate the data network service you purchase. Then you can use the data network to surf the Internet.

Warmly Tips: Please try to activate the data network you purchase within one month, or it will expire.

You can go to Settings>(Dual cards and) Mobile network to turn on VoLTE HD Call.

Warmly Tips: For some phones, VoLTE is enabled by default or can be found in Settings>Phone.

Go to Settings>(Dual cards and) Mobile network>iRoaming>Service>Hot Regions>touch See All, select the country or region you are going to, then choose the most appropriate Data Package. Touch Buy to purchase it.

iRoaming is a virtual SIM service that allows you to use the local data network without having to purchase a local SIM card when traveling abroad for a short period of time. Before going abroad, first purchase the overseas data network service through iRoaming, then activate it after going abroad.

Please don`t worry, perform these steps as below for a try:

1. Make sure your SIM card and phone support VoLTE;

2. Insert your SIM card to another phone which supports VoLTE to check if there is the same issue. If yes, we recommend you ask your carrier whether VoLTE network is covered where you live;

3. Insert another SIM card from the same carrier into your phone to check if there is the same issue. If not, we recommend you change an SIM card;

4. Upgrade your phone to the latest version;
