[Q] Provider Problem with Custom Rom - LG Optimus Black

Hello !
I have an Optimus Black with Cyanogenmod 4.1.2. The Phone works well, i have the same SIM Card inside which i bought with the Phone from my Provider.
Now i want to gift the phone to my son, but for that i want my Optimus to accept another SIM Card/Provider.
I thought the Phone is open when i flash the ROM and wipe any Data.
Using any other SIM Card, except my Providers card, causes a Network error.
No Network scan can be made in the Configuration menu.
Or is it a ROM Bug ?
Any idea ?
regards VirtuAl

rebooting with new sim card

Hy
I have a little problem!
I got a new sim card in my motorola milestone. But the phone keeps rebooting all the time! sometimes i am able to write a text but if i wanna call its too much and a reboot starts!
i have tried another sim card in my phone and it works!
i have tried another phone with my card and it works!
i dont understand if its a sim card problem or phone problem.
i have 2.3.7 kernel 2.6.32.9 cyanogenMod 7.2.0
does anyone help me out?
Tell your carrier that your phone keeps rebooting with the SIM card they gave you and they unless they replace the SIM for free, you see no reason to continue service.
the problem is that my sim card works in other phones.
Now i got my milestone back to the stock and it seems to work.
I think it was the cyano 7 but now without it my phone sucks!

[Q] LG P990 sim card no inserted

Hi gys! I need your help!!! I run official ICS on my LG P990 with my vodafone sim card.
I wanted to gift my phone but when i put cosmote sim(other network) phone doesnt see it, its like no sim card.
I enter menu to manually change the network to cosmote but says "sims doesnt allow it). Do you know whats happenig? It a hardware faulure or it is locked to a network? I already try (and payed too) to unlock my phone with code with no success.
Please help!!!!!
Is your phone network branded? If so you could download and install an European open stock rom and flash that to get around the network permissions.

It was a hardware error! Sim card reader fails and i have replace it. Now everything working fine!
Now that it works well now, cong! I've meet this problem before and it was cause by the rom.

[Q] No simlock but no network

Hello I have an unlocked samsung ace. I got him rooting and I installed a custom rom. Everything works fine but now I placed a SIM card from another provider. The phone starts completely without error but I have no network. The SIM card is good because he does it in other phones.
Does anyone know the solution?

Hello,
I bought a new sim card in Amsterdam because I will have to stay there for a while. However, when I insert card in HTC desire C it doesn't find any networks. It recognizes that it is 'lebara' sim card, but when I try looking for networks it just says 'error while connecting to networks'.
Frequencies are the same as in my old country (Lithuania) and my old sim works perfectly. What could be the reason and a fix?
by the way, im using cm 11 rom, RC2 or RC3 release, i dont remember
question solved - i was given outdated card. expired date...

Mi3W SIM not recognised - peculiar case

Hi All. I have quite a strange case of my SIM card not being recognised by my Xiaomi Mi3W.
Here's what happed.
1) Purchased phone off friend with stock MIUI - all working
2) Inserted my SIM with mobile carrier A (still with stock MIUI) - all working
3) Flashed Cyanogenmod 12.1 Cancro on phone - all working
4) 3 days later, changed mobile carrier to carrier B - not working
Original SIM card from carrier A was in phone when my account with carrier A was erased.
Since my number was ported from carrier A to carrier B, the phone has had issues recognising SIM cards.
5) SIM card from carrier B not working, and neither are other SIM cards
6) I have checked with carrier B and my phone is definitely compatible with their network.
7) My SIM card is working on all other phones
8) The weird bit is that at the shop of carrier B, the shop assistant SIM worked, but a brand new SIM didn't.
9) I have tried reflashing Cyanogenmod. - not working
10) I have updated Cyanogenmod. - not working
11) SIM tray looks clear of dust/obstacles - still not working
System details: imgur dot com/zwiD3pR <--(sorry new acc)
Not to sure where to go to next. I guess I can try back to MIUI or stock android, but I'd love to hear what you think.
Try doing a factory reset (assuming you haven't as mentioned in post)
If still not working, remove the sim, flash the stock miui back through fastboot, guides of which can be found in more detail in the miui forums
See if the sim works or not, if it does try rooting and installing recovery
Then flash the cyanogenmod and see if the issue still persists
