Is there any way AT ALL to make a cell phone that IS NOT compatible in the USA to be compatible in the USA? - usa to australia phone card

There are many cell phones are operating only in the circles of the foreign networks. I really want a phone that says it will work with all SIM cards in Germany / Europe and Australia. Is it even possible, maybe even some of the engineer wiriring work, so that the phone supports a SIM card from the United States? All technical phone there?
