I'm sorry about the issue. Have a phone number would require a carrier's service. Do you if your iPhone 5s belongs to a wireless / phone service carrier, such as AT&T or Verizon, or Sprint or T-Mobile, etc.?
Have you checked with any phone service carrier?

Can you go to a local AT&T store or call AT&T wireless in order to obtain a phone number / service?
