You should be able to access your cell phone records either through your monthly phone bill, if you have one, or your online account. If you no longer have a copy of your phone bill or are unable to find your records in your online account, contact the phone company.
Your cell phone records offer information such as the date and length of a phone call. If you are seeking information that is not available in your phone records, you may need to contact your cell phone provider for assistance. For example, if you are receiving phone calls from a blocked number, your phone provider should be able to provide help in identifying the number.
