If you do not have a Social Security Number (SSN), you will be required to make a deposit before being allowed to sign a contract with a mobile phone company. You will not be able to get an SSN until you have employment. To avoid the deposit you may wish to purchase pre-paid service.
Be sure to check rates carefully, international calls are billed differently than calls made within the country and can quickly cause your bill to grow to very large amounts.
To set up your service, whether it is pre-paid or contract, you will need to visit a provider in person. There are several different mobile phone carriers in Kokomo. Below is a listing of some of the most common carriers and their locations in the area.
