If a Nigerian mobile phone is roaming in the United States (or anywhere else in the world), you can call it by dialing the Nigerian mobile number, beginning with country code +234. Drop the trunk prefix '0' from the beginning of the Nigerian domestic number and replace it with country code +234.
If a mobile from anywhere in the world besides Nigeria is roaming in the United States, you cannot reach it by dialing a Nigerian number.
To call a mobile phone that is roaming in the United States, you dial the number the same way that you would if the mobile is in its home country. The same is true no matter what country you're roaming in.

If his provider has an overseas roaming agreement, then all you have to do is call his number just as usual.
In most cases, just dial the US number the way you normally would, although the cell phone's owner may pay very expensive international roaming charges, depending on the terms of their contract.
You can call them. If they answer, the phone is on.

Dial the Australian mobile number, exactly the same way that you do when the mobile is at home in Australia. The mobile phone network will automatically route the call to the mobile, wherever it is roaming, and the roaming user will pay any applicable surcharges.
Because it is not using the home tower. In my zip code (CDMA market), Verizon and US Cellular are the two providers. My Tracfone should be using Verizon towers, but it is using the US Cellular towers and showing roaming on the phone in the home area. Whenever the home towers are not being used, the Tracfone will show roaming on a CDMA phone. GSM phones are a different story.
you call them then you scream on the phone
