N78 Persistent 'Sim Card Registration Message'

Question

 I have scoured the internet for answers on this problem, and i cannot find anyone with the same problem as me, so hopefully one of you could shed some light on this problem;
I recently purchased the N78 from my sister in November-ish of last year, it was a SIM free one, so i was able to put my Three (3) SIM card in (She was recently on 02 if that helps)  it worked fine for say, about a month maybe, until the message 'SIM card registration failed' kept appearing, i just ignored this for a while as i presumed it was something to do with it being on 02 for a bit.  after a few more weeks it kept appearing more and more, at that point all the signal bar went to 0 and i couldn't make or receive calls, unless i switched it off then back on again, after that it worked fine, and i was able to call and send/recieve texts (until the message appeared again).  After a few more weeks this kept happening more and more and I kept missing important calls and texts (as I did not know when it would happen, it just happened at random intervals)I contacted 3 about this problem, and they said it was due to the faulty SIM card, so they sent me a new one, which worked for a while, then the same thing happened again.  So I eventually gave up using this phone altogether, and used it solely for the connection to wireless internet and for the music player, which both worked fine.
Yet, earlier I attempted to put my SIM card back into the phone and it stopped working altogether, the message appeared all the time and i could not make a call or send a text whatsoever.I put the same SIM card into 2 different phones, and it worked fine, except my old Nokia 6288 'SIM Card Registration Failed' kept coming up, and has done for quite some time, but it didn't interfere with sending texts or making calls at all.I put a different SIM card into the Nokia N78, and it works perfectly fine, the message does not appear!
So, in short i cannot use my SIM card in my N78, but i can use it in other phones, yet I can use other SIM cards in this phone with no problem.
Any help at all would be greatly apprecaited.

sees like you have had exactly the same problem as me. my second-last phone was a 6288 and after about a year of use, I had that SIM registration failed message come up. had nothing to do with my network (i am on 3 Australia), and i am sure it was just the firmware of the phone playing up. i just ignored it and restarted the phone when i had to. after a while, it went away. I haven't had the same problems on my N78 that i purchased about six months back, but if you have early firmware version on your N78 (say the original 10.136, 11 or 12.046(, I would suggest seeing if there is an upgrade for your phone. there should be, as 20.149 and 21.002 has been rolled out pretty recently. I am still with 3 and haven't used any other network's SIM card so can't vouch for the experiences you have with other network providers. But as happened with 6288, i don't think its the SIM card or 3 or O2, i think its the phone itself.
if you can't find a firmware update for your phone via NSU or FOTA, then take your phone to a local Nokia Care Centre and they'lll be able to upgrade your firmware for you. hopefully it all goes well for you , tell us how it all goes.
If you found this or someone's comments helpful or like what that person has to say, please give some Kudos to their post!
