What to have ready before you call Assurance Wireless

Your enrollment or application ID, the phone number on the account, and the exact wording of any error or status you are seeing. Call from a different phone than the Assurance Wireless line if the handset itself is the problem. For a stuck application, the fix usually lives with the National Verifier documents rather than the carrier, so have your benefit letter to hand and check its date is inside 12 months.
