When I brought my Samsung A20 phone over from Walmart Family Mobile prepaid to Verizon prepaid a few years ago, I was given a Verizon branded SD card. Now, after a few years more, I want to expand the SD card up to 512GB which is the most this phone will accept. My questions are
1. The new SD card is SanDisk branded. Will this new SD card continue to work on the Verizon network so the phone will continue to receive uninterrupted service?
2. Will everything on the old SD card remain in the phones internal memory be automatically switched to the new SD card once installed?
3. Is there something else that needs to be done before the actual switch out of the SD card to make sure nothing is lost? (apps, contacts, photos, ETC)
