Thanks for the post Osborne42 and welcome to our community.
So we can do more checks for this, do you know the IMEI number? Please don't post this publicly I just need to confirm you have this to hand and then I'll pop you over a private message to pass security so we can get an unlock code for the handset in question.
Hi. I have just recievied a new sim that Virgin sent out. When I put it into my phone all I get is a Sim Not valid error message. I have power cycled many times and tried to reseat the sim many times. It has no effect. Typing in the unlock code also did nothing other than clear the screen and give me "sim not valid again". I have tried this code only 1 time.
I put my old sim back in and my phone works fine again.
My device is a nokia 2310 purchased from Virgin. (its old) I have my IMEI and account details.
I have tried calling 789 multiple times and just end up sat listening to a voice telling me to try the internet.
Hello - Is "SIM not valid" the same as "Network Key?" I posted a separate message about this problem with a new sim on my elderly neighbours phone last Wednesday but haven't had a reply but I see Virgin team members are active on this thread. Sorry to but in but can someone help please? thanks
I did a lot of looking into the Nokia unlocking issues as it affects me. Affected Nokias are hardlocked using software. An unlocking code won't work on these and repeated attempts will disable the phone. The only way to unlock these Nokias is to download new software into the handset (it's probably easier to just get a new handset). I don't think VM understood this about locked Nokia handsets.
We found the only way for the new sim to work was to purchase a newer model phone for my 91 year old grandmother. We ended up getting a Nokia 105 (2019). Virgin sent 2 SIMs this did not resolve the issue with the old phone. I thought I would post this incase it helps anyone else as I wasted a lot of time trying to resolve it.
