Upon arrival of your destination, insert your AIRSIM into the mobile phone. Please switch on the Data Service and Data Roaming in your mobile phone (Steps 1 & 2 below).
Please wait for about 3 minutes, AIRSIM will search for the network automatically, some notices will be popped up and please click OK to move onto next step.
After 3 minutes, the setup should be completed. The phone should display the signal and the Carrier Name. You can use the internet service. If you cannot have access to the internet, please restart the mobile phone.
APN will be set automatically in most Asia regions. If you cannot access the internet, please check if the APN is correctly set. Manual APN setup may be required in some destinations such as Europe. Please refer to steps 3, 4 below and the APN and Carrier list. For example you are in Singapore, the APN should be 3gnet. If you are in Europe, the APN should be uinternet. Please enter the corresponding APN according to the list.
If the connection fails, it may be due to the poor coverage at the current location, please restart the mobile phone at other location.
When you travel across the border to another country, you may need to restart the mobile phone twice for some mobile phone models.
For some mobile phone models, they cannot search and select the network automatically, you need to select the Carrier network manually, please refer to steps 5, 6 below and the APN & Carrier list. For example you are in Vietnam, the carrier is VIETTEL (according to the list).
If you still cannot use the data service or connect to the 4G network (if applicable), please restart the mobile phone.
After using AIRSIM or switch to other SIM card, please remember to turn off data roaming function, in order to avoid unnecessary roaming charges.
