I purchased a Samsung Galaxy S20 Plus yesterday and whoopsed on the activation. In the past I've transferred my old SIM card to the new phone and activated without trouble, but this I forgot to turn off my S20 before inserting my old SIM, and I'm pretty sure I broke the internet. I tried using the new SIM card as well, but to no avail. Unfortunately, neither phone now works, and neither will activate on Verizon's network.According to my account, the S20 is active, but for some strange reason, the SIM card ICCID number associated with the S20 on my account is neither the old SIM number nor the new SIM number. I've tried reactivating my old Moto G6, but that doesn't work either. To add insult to injury, Verizon keeps trying to verify my account by sending a verification code to the number that doesn't work. Fortunately I have a second line I can use for account verification, but I don't know what else to do at this point.Verizon's automated response says their service hours begin at 8am eastern, but I've been trying since then, and no answer, and every time I try online chat I get an error. I'm hoping the forums are more active and I can get a tech support rep to contact me. Thanks in advance to any help anyone can provide!

Any idea just how long I should "rest" (assured or otherwise) without having my backup system for smartphone communication up and running?

Your customer service folks and tech support people are aware there's a problem as other customers have been calling in for assistance and complaining that what used to work on the Verizon website works no longer.I have failed each and every time I've attempted to use the online "Activate device on an existing line" process to go from one of my phones to another (8+ to 6+, 8+ to S5, and the reverse of each). And I have succeeded every time I've called in and had your techs or customer service people perform the switch.As best I understand what I've been told, your folks are having to override inaccurate SIM identification somewhere in your computer system. They can "see" the ICCID of the (replacing) device in question on their "live" display, but that's not the SIM the computer has in its records. I suspect someone got lazy or careless and miscoded the process by which one device/SIM pairing is replaced by another, completely different device/SIM pairing. Per your documentation, the expected switching mode is to take the SIM from the "old" phone (was activated) and install it in the "new" phone (to be activated).Please note that I've tried using both the New and the Previously Known (I forget the exact phrasing) forks to designate the replacing device. Neither route provides joy.

So did this ever get fixed? I'm having the same issue. Bright over an unlocked s20 ultra, byod too shows it's compatible with the network, reps have checked dmd which also shows it's compatible, however when we try to activate a sim card with device id a error message stating that sim is incompatible with device appears.Using a provisional id will get the sim card activated and I can use voice and text but no data.

@akwill25 Thanks for clarifying what you're experiencing. I have personally switched devices on my account via my My Verizon online account. Does this happen when trying to switch to one specific device, or does this happen no matter which device you choose? We may need to submit a ticket to our IT Department if we can determine this is an issue with your specific online My Verizon account. AnthonyTa_VZW

My main phone is an iPhone 8 Plus. My primary backup phone is an iPhone 6 Plus. My secondary backup phone is a Samsung Galaxy S5. All phones were either purchased directly from Verizon or purchased independently and only ever activated on Verizon.My problem, as stated, is that the ONLINE "Activate device on an existing line" process does not work. I know both backup phones CAN work as I've called in and had Verizon reps MANUALLY switch me over (and back). That does NOT change the fact that I can no longer do this myself using your 24x7 online process. Instead I must hope that my need for a backup phone doesn't present itself after hours, during holidays, or when you're short-staffed due to viruses, cutbacks, or general orneriness.So, what help can you provide to solve my problem?

@akwill25 I'm sorry to learn you're experiencing problems activating your spare device on your wireless account. I'd love to assist. What model phone are you trying to switch to and activate? What exactly happens when you attempt the switch? AnthonyTa_VZW

No data is no good. I understand a great deal of time has been put into this this far. To step back, what are the results of entering in the IMEI here?

That page won't load for me. But if that link is supposed to take me to the byod check device page, I answered that in my first comment
