Exactly the same way you send a text to that mobile if it's in America.
Yes, provided that the mobile user has enabled international roaming. You just enter the Australian mobile number exactly the same way you do when it is in Australia.
For American numbers, prefix with country code +1
To send a text to a North American (USA, Canada, etc.) mobile phone from an Australian mobile phone (or any GSM mobile anywhere in the world), simply prefix the North American area code and number with country code +1. For example, to send a text to (212) 555-0123, send it to +12125550123.(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
Virgin Mobile Australia's population is 2,008.
If calling from the UK, dial the same number in the same format that you always use. If calling from Australia, you'll need +44 to be added to the beginning of the UK number, and remember to omit the leading 0 from that 07 mobile number.
I used code 0061 to text Australia
