We recommend all students have a cell phone while at UWM. You can either bring a phone with a plan from home or arrange to have services here in the U.S. Although international students sometimes encounter problems enrolling in a cell phone plan without a social security number, some providers are willing to offer services without it. Explain your situation with an employee at one of the provider stores and they should be able to work something out.
Information on cell phone provider stores that are located near campus is below:
