To make a call using your United Global SIM you’ll need to dial the full international number no matter what country you are calling from, or what country you are calling to. When dialling both locally and international remember to dial the full international format for all numbers.

 

Step 1. Dial the number you wish to call in full international format. For example, to call an Australian Mobile press + then enter the country code and drop the zero. You would dial on your Global SIM +61 491 570 110

To call the Canadian number 604-259-1641. You would dial +1-604-259-1649

Step 2. Press the call button. In a few seconds your phone will ring and you need to answer this call.

Step 3. Your call will be connected. At the end of the call you will receive a message with the cost of your last call.

 

Tip!  To make it even easier to dial, make sure you change your favourite contacts into the international format. You’ll be able to dial them using this format when you return to Australia so you won’t need to switch the numbers back.

 

Troubleshooting calls

If you find that you are dialling correctly but still cannot make a call, please manually select a different carrier in your phone Settings. To do this on most phones you can go to Settings > More Network or Carrier > Switch Automatic Off and select another network available.

 

If you still have difficulty making the call, try replacing the + with a * and adding a # at the end. For example, *61 491 570 110# for the Australian number or *1-604-259-1649# for the Canadian number. 

To call you directly from a mobile:

  • enter ‘+’ (plus sign)
  • then your Global SIM number starting with 44

Example: from any mobile phone dial: + 44 ### ### ####

Note:  the + sign is recognised by all networks in the world as the universal exit code for mobiles instead of dialling a exit code.

Hint: Generally you will find the '+' sign on either the '0' button, or one of the buttons either side of the '0' button, by holding the 0 down it will convert to a + or press the respective button on your phone.

To call you directly from a landline: 

  • enter International Exit Code
  • then your Global Sim number

Example: from an Australian landline dial: 0011 44 ### ### ####

Hint:  International Exit Codes or International Direct Dialling Codes (IDD) are required to dial internationally out of a country. 

People calling you on your Global SIM will be charged for a call to the UK. It will vary on the carrier and agreements the person has with their provider. You can also log in online and activate a United Global SIM Local Number service to alleviate these costs. 

A Local Number will allow your friends and family to contact you by using a Local Number instead of your Global SIM phone number. This means that they will be charged at a local rate.

To find out more about Local Numbers please see the Common Questions tab on Local Numbers.
