I have a Samung s10 and constantly losing service and have no data. Replace 4g card then replaced phone all together still have the same problem. My wife has a iPhone 10 with the exact problem and did the same with the 4g card and phone replacement with the same results. Most of this started with about a year ago but got worse when 5g was introduced. Just need to find out what can be done because I do not want switch carriers. I've had Verizon since '96 (bell telephone then) and love to keep them because living in jersey and working in NYC I've seen all kinds of disasters first hand (9/11-Hurricane Sandy ect.) and always had service.
