First I would check the phone to see if it saved the greeting to its files. Some phones do and some don’t. If you are unable to find the voicemail greeting file, google the question for your type of phone. If you’re unable to find it or do it, call youe cell phone carrier to see if they can help. Some carriers still save voicemail greetings on their systems. It’s a great reminder though that if you have a greeting you really want to keep, to make sure you record it and save it to your computer and to a flash drive or cloud drive for good measure. Hope that helps! Laura
