TLDR: Sent my phone in to Samsung for repair, comes back without the ability to use as a phone due to network lock. Sent it back in to get it unlocked, they sent it back saying they can't fix it.
Purchased my S10+ when it was released in 2018 from Mobileciti, last year the phone had extensive water damage and Samsung agreed to fully fix it. 7 months later (I got another phone in the meantime), tried to use it and noticed there was still water in the cameras but the main issue is that now my phone is not able to take any sim cards. It shows the error message " Enter network unlock code. Your phone isn't allowed to use this SIM card ". Obviously, the phone was unlocked when I purchased it, I've tried a few SIMs and now the technicians have tried a few SIMs and nothing works.
The case manager has replied with "they can try to wipe the device to see if that resolves the issue but the technicians believe that it is a network issue lock." I said they can do whatever they like as long but I will not accept it back if it's not working. The next day I get a text saying 'your phone has been despatched to the store', so I immediately called up Tecworks (their repair centre) and asked them to double check that its working as I just got an email the previous day saying it's not. Called back and was reassured, yes its fixed we've tested it with a few SIMs.
Went all the way back there today, and since I had a bad feeling about it, I inserted in my SIM and straightaway 'SIM card invalid'. Called Tecworks and they said 'oh we can't fix this, Samsung needs to fix it'. Now I'm pissed AF as I didn't say yes to sending the phone back in the first place when they asked. Called the Samsung VOC number and after an hour they just said, ask the store to send it back to Tecworks and then we'll see what we can do if it's not fixed. She offered me some loyalty discount in lieu of it but I said no, I want a working phone.
If it can't be fixed, what would be a reasonable solution that I can push for? I mean, I realise that its unrealistic for me to ask for a new S23+ as the phone would be in it's 5th year by now. I don't want credits and all that as I don't need another TV/tablet/watch and we just got the s22 and s23 ultra recently. I don't want to use the credit towards another phone as I would still need to outlay money for another one unless its low tier.
Thanks for reading, been a real frustrating day.
Sorry can't help you, but feel your pain. This seems like another failed Samsung after market support story.
