WiFi Calling allows you to use your existing U Mobile number to make and receive calls using a WiFi connection. Your WiFi hotspot effectively becomes a U Mobile network tower. Enjoy huge savings while overseas when calling Malaysian numbers at a local call rate with no roaming surcharge.
To activate WiFi Calling, follow these steps:
Step 1: Insert U Mobile SIM into your iPhone.
Step 2: Activate the service. Text < WIFICALLING ON > via SMS to 28118.
Step 3: Enable WiFi Calling. Select Settings > Phone > Wi-Fi Calling > toggle to ON.
Step 4: Connect to a WiFi network.
Step 5: If WiFi Calling is activated, you will see “U Mobile WiFi”. All calls will then be made using WiFi Calling.
Most devices and phones can support WiFi Calling. Kindly check with the device or phone manufacturer for compatibility.
Yes, it does. You will need to update to the latest iOS firmware and install the latest “carrier bundle”. To install the bundle, go to Settings > General > About > Install.
All U Mobile subscribers on postpaid and prepaid plans are eligible for WiFi Calling, as long as your rate plan supports “voice call”. It is not available for “data only” plans such as Postpaid MB.
All you need is a private or public WiFi network that is connected to the Internet. However, the recommended wireless LAN is either the 802.11n or 802.11ac standards as they provide a better data quality connection.
Yes, a valid and active U Mobile SIM card is required. If your line is barred, suspended or terminated, you will not be able to make a call. If you have a dual-SIM phone, please insert your U Mobile SIM into Slot 1.
You can retry setting up WiFi Calling again. If it still doesn’t work, try out these steps instead:
Step 1: Connect to a different WiFi network with a stronger signal.
Step 2: Turn the WiFi Calling OFF and ON again
Step 3: Restart your phone
Note: Some corporate networks may block WiFi Calls. If this continues, call your network administrator for assistance.
There are a few possible reasons:
WiFi Calling requires an adequate Wi-Fi signal strength before initiating the automatic connection to WiFi Calling. Move to an area where the signal’s connection is stronger.
If the WiFi network has a captive portal (Eg. Starbucks which requires log in), you may have to launch your browser and sign in to the network with the provided username/password.
You do not need to register for IDD or IR service in order for you to use the WiFi Calling service when abroad to call back to Malaysia. However, if you need to make any outgoing IDD calls, you will need to enable IDD services.
To make a call abroad without using the WiFi Calling service, you will need to enable the IR service as well.
No, you will not be charged for incoming calls while using WiFi Calling abroad.
Yes, your WiFi calls will be disconnected if you move out of the WiFi coverage area. You will then need to make another call when you are in a WiFi coverage area again.
Yes, you can make calls to any number through U Mobile WiFi Calling as per usual.
Yes, you can access the *118# menu when you are on WiFi Calling. But if you have any issue accessing the menu, please turn off the WiFi Calling and try again.
Yes, you can send an SMS even though you are connected to WiFi Calling. However, the SMS will be sent through your mobile network instead of the connected WiFi network.
We are working to enable SMS to be sent over WiFi networks. Please re-visit our website at https://www.u.com.my/business/plans/data-services/wifi-calling for the latest information and updates.
Emergency services number 112 and 999 are routed through your normal mobile network service. If you turn on WiFi Calling and cellular service isn't available, the emergency call will use WiFi Calling to route you to a Malaysian emergency service number.
When your phone is connected to a WiFi hotspot, the call you make will be sent to the U Mobile network via the internet. From here, U Mobile will then connect your call to the recipient.
