I'm not to tech savvy so please don't judge! I just upgraded from my S7 Active to a S20FE. I put my old SIM card in the new phone. Some of my contacts transferred over but not all of them. Is there any way to get them in there without putting the ones that didn't transfer in one by one? Any help would be appreciated!
If you get your contacts back, I recommend creating a contact back up that saves as a CSV file, then save it on the cloud, or transfer it to you PC and back it up again as you alter your contacts.
