Use the full international number format starting with + and dropping the first 0.
For example to text the Australian number 0491 570 110, you would enter +61 491 570 110
If you are using an iPhone, you may receive jumbled messages due to a feature in your iPhone called iMessages or FaceTime.

You may also be incurring charges related to iMessages and/or FaceTime. You should switch both of these OFF in your settings when using your Global SIM.  

To switch iMessages OFF
Step 1. Go to Settings on your iPhone 
Step 2. Scroll down to 'Messages' 
Step 3. Switch off 'iMessage' at the very top 

To switch FaceTime OFF
Step 1. Go to Settings on your iPhone
Step 2. Scroll down to 'FaceTime'
Step 3. Switch 'FaceTime' off at the very top of the page

Anyone sending you a text message would dial as they would for any international number (starting with + and then the full international number).

As you have been given a full international number, you simply just need to add + in front of the Global SIM number. The same format is used for calling and sending texts to the Global SIM.

Example: To text the Global SIM number 44 ### ##### they would send it to +44 ### #####

You can also send text messages to the Global SIM for free online. Use Cover-More Global SIM's free texting service.

If you are already using the correct SMS format and the messages are still not going through, please go to your Contacts list and edit the contact manually, changing the number to the full international format by including a +, international code, state code and dropping the first 0. 

Example: Instead of having the contact saved in the national format 0491 570 110 you should change it to +61 491 570 110 

This is a standard format around the world and you will not be required to change it again when you return home. Some smart phones will recognise the number you are trying to text and they will reformat the number and send the message from your contacts automatically.

Note: Some smart phones also keep a record of text messages in one single conversation. This means that because you previously messaged this number in local format, your smart phone will continue to revert the phone number into local format which blocks you from sending international SMS. Note that this issue is common among iPhones and you must follow the steps:

Step 1. Select the person you are messaging and delete the SMS history

Step 2. Make sure they are not saved in your contacts in the local format

Step 3. Make sure they are not saved in your favourite contacts

Step 4. Please ensure that the local format phone number is removed from any part that your smartphone may be picking up the number from

Step 5. Please retry sending the SMS. If issue persists please try deleting this contact altogether and then re-adding them to your contact list in international format.
