unlocked phone suddenly says 'invalid sim' - Upgrading, Modifying and Unlocking

I broke and replaced the screen in my unlocked upgraded flashed-ROM wallaby and the unit now starts up and reports invalid SIM.
Is there any solution or should I re-flash the rom again and see if that works, hope for the best?

Try the SIM in a different (unlocked) phone, to make sure the SIM isn't fried. If the SIM is fried, you can get a new one from your provider. SIMs do get fried sometimes -- it happened to me a couple months back. Fortunately my provider (Cingular) has a shop just down the road from me, and they burned a new SIM in 5 minutes.

I apologise, I should have said
Sorry, I should have said, it does work in another machine and as I said, it did work immediately I used the xda flashing process to upgrade the ROM in this very unit before I dropped it.
Everything else in the new ROM seems to work which makes it infuriating that it wont recognise the SIM. I even tried calling T-Mobile and asking them if they could see the SIM on their network and they couldn't.
(I even have one of those SIM copying devices they send you free for some unknown reason when they want you to upgrade your service to some kind of higher level SIM card. I was wondering if I should try to use it again but as mine does work, this, like the whole copying device, seemed a bit academic)

T-mobile Dash Sim Card Error...

Are you sure the phone is SIM unlocked? Or if the SIM card is the right one for the phone? There's really only one correct way to insert a SIM card....Are you sure this isn't an ID10T error? PEBKAC error maybe?

What network do you have, and where did you get your phone from. I can try to help you out from here just let me know the network and where you have your phone from. Also tell me if the phone is tmobile branded (if it says tmobile on it in the front).

I have the same problem. When I was running WM6, I would get this error multiple times throughout the day and I'd have to turn the PHONE function off then back on or sometimes I'd even have to do a soft-reset to get my Dash to recognize my SIM. Now that I have flashed my to Kavanna's WM6.1 I only get this error once a day, but I'd like to know how to stop it from happening.
Network: T-Moblie
Bought From: Ebay
Branded: Yes
Sim Unlocked: No
App Unlocked: Yes
WM 6.1 Standard
Radio Version 4.1.13.51_03.07.90
RIL Version 2.002
CE OS 5.2.19700 (Build 19700.1.1.0)
Thanks in advance.
If you have not exchanged your SIM in a while it could just be that the SIM is old, yeah it happens. It is free to swap out your SIM card at any T-Mobile retail store. I had this problem about a year ago and I simply went to T-Mobile and they gave me a new SIM (they just copy the contents of your SIM to a new one and program it with your number. Solved my SIM error message.
Also your SIM may be inserted wrong, it could be dirty (the contacts can 'gloss over') or there is dirt / dust in the SIM holder.. blow it out.
If all the above fails then it is the device, if under warranty have it replaced.
I had the SIM card replaced by T-Mobile about a month ago and that solved the problem for a couple of days, but now it's back. I made sure it is aligned right and clean.
Any other ideas?

Sim Failure

I am using the Dopod version of this device on T-Mobile's network. My sim worked fine for quite a while, but now most of the time when I power the phone on is does not detect my sim. Sometimes it will, but later I check my phone and see that the sim is no longer working. I've tested other sims, and the sim is not faulty. I've also flashed a few different roms to see if I'd have any luck and did not.
Maybe the sim is moving out of place??? Something like that used to happen with one of my older Moto Q's. I used a piece of paper to keep it in place, maybe you can try that? Just a suggestion!

Weird situation: No service after installing Lovebabyjing ROM

The reason I say this is a weird situation is because I'm actually using an old Suncom SIM card. My girlfriend's phone finally died after going through numerous drops/abuse for the past few years, so I was going to give her my old Dash. Now, the official ROM does that "network is locked" thing, so I figured I would a custom ROM. Well, I was able to start up the phone successfully and use it fully with the Suncom SIM inserted, but it does not find the T-mobile signal.
Is there a way around this, or is she going to have to go to T-mobile and have her SIM converted over to a T-mobile one?

is your phone sim unlock? In order to use other provider< you phone must be sim unlocked>
good luck
That's the thing though, it's not being used by a DIFFERENT provider, but actually by the SAME provider. The only problem is that the SIM card is from the old company before the two merged, so I'm guessing that makes a difference.

Maybe as we have company's that use same carrier yet the sims can't be used without unlock phone.
Eg: BT, Asda both use Vodaphone yet can't have a Vodaphone or Asda SIM in a BT phone without unlock...

Problems with new SIM card LG G3

Hi there,
I am a so far satisfied owner of a G3 but since 10 days I have been having an issue with my G3 and I wanted to ask around if someone here has an idea or some thought that could help.
My situation is the following:
About 2 weeks ago I switched my mobile service provider. When my new SIM card from my new provider arrived I tried the SIM card in my G3 but there was just the massage "no sim card found" and no possibility to type in your PIN. So I thought maybe I got a defective SIM card, it happens. I ordered a new one but the problem remained with the new card in my G3 aswell, still no pssibility to type in my PIN. So I tried troubleshooting and started trying the SIM cards in diffrent phones. In other phones the SIM card from the new provider worked perfectly and I was able to type in my PIN like it should be. When I tried putting other SIM cards in my G3 (from my Mom, Dad etc. and also from different providers) none of them worked in my G3. Even my sisters SIM card from the same new provider AND she has also a G3. So far it seems that the my G3s SIM card reader is broken.
The weird thing is that when I put in my G3 my old SIM card from the old provider the prompt to type in my PIN appears as normal as ever. If I type in my PIN the phone accepts the PIN normally. There is just no reception which is normal because I am not with my old provider anymore. I also have to add that the phone appears not to have SIM lock. I bought it from a private seller but he bought the G3 with a vodafone contract and I was with O2 at that time and the phone worked perfectly. Just until I switched from O2 to Congstar (Telekom) the problem began.
So I thought I just send it back to LG because I still have warranty on the device. The phone is rooted so I need to admit that it was not that clever to send the phone in without rolling back the rooting. Today I got a letter from the repair service from LG with an estimate of cost which means no surprise, no warranty for me. You guess right, the reason is the rooting they write they need to change the whole mainboard. For me this sound like plain bull**** because on the document they send it seems like the first thing they check is a rooting and if the device is rooted then thats the cause. But ok it was pretty stupid from me not to unroot it, I know.
Now I wanted to ask you if someone had a similar problem with their G3 or has an idea what the cause could be. Like mentioned above with my old SIM card the phone worked normally. Just the new cards and all other cards, even another O2 card did not work. Is it possible that just one and only one SIM cards gets accepted from the phone?
Sorry for the long post. I am thankful for any advice.
Best regards,
Patrick
I'll have my phone back tomorrow. If someone still has an idea I would be very thankful about some thoughts or suggestions.
Thanks!

It seems your phone is Sim locked.
You need to find the unlocking code that you need to put in the hidden menu.
Google for LG G3 Sim unlock.
Sent from my phone
Hi,
thanks for your reply! Iam not sure it is because of sim lock- Because the phone came with a vodafone contract but when I bought it I was with O2. And with my old sim card from O2 the phone worked perfectly. Weird is that when I put in a different O2 sim card the pin prompt also did not appear. Same with any other sim card ...
Thanks,
Patrick
Or did maybe someone have a similar experience with a different phone?

Hi again,
I tried some more things but still nothing helped.
The things I tried were:
- unrooting the phone and factory reset
- reflash radios
- try completely diffrent rom (CM)
Still I have no idea what the cause could be. Maybe the sim card reader is just broken. Just weird that it reads my deactivated sim card.
I would really appreciate it if someone has an idea or some similar experience..
Thanks!
You can buy an unlock code for 3.5-4€ , works for any LG G3 variant
Try it
Ok, thanks! I will try it!
So I just looked at what I have to do and tried the combination 2945#*855# to see where I have to type in the code. The thing is when I choose any one of the appearing options like netlock etc. the phone says "this phone is permanently locked" and there is no possibility to type in any code...
How the hell is my phone completely locked...

Galaxy S4 T-Mobile (SGH-M919) SIM Not Detected

I have started having SIM card issues about a year ago, and it started with their new SIM cards. They advised me to get a new one, so I could use tethering. Since I have, I kept randomly getting "No SIM detected, please restart to detect your SIM" randomly, and it has been really annoying. I have replaced the SIM slot, and cleaned it multiple times, sometimes it works afterwards sometimes not. It seems to me like this would be a hardware issue, but could it possibly be software?
I notice on the different SIM slots I have bought, there are different revision numbers. What is the latest revision, that has the best contacts? Taking one apart, I noticed the contacts are crap. VERY small, that barely make contact. I was thinking of de-soldering the crappy SIM tray, and finding an SMD that has ball-bearing contacts, has anyone ever done this?
Last month, I accidentally left my SGH-M919 in my pocket and the motherboard was fried when it got put in the wash. I tried resurrecting it with the RIFF, but the eMMC was dead. Anyways, I managed to find a new motherboard with a clean IMEI, and got the lowest android version possible (so I could use "CF Auto Root" and "Region Lock Away").
I can insert my SIMple mobile SIM and it detects it, and it detects my old T-Mobile SIMs, but it will not detect my active one. The version I had that partially worked of Android was 4.4.4, this "new" motherboard has 4.3.
Is it possible that, since the board has older baseband, it will not detect new SIMs? I am afraid to upgrade to the latest OTA as then I most likely cannot use "CF Region Lock Away". Can I root it first, then use the latest custom MOD, or must I do the OTA to get the baseband and low-level radio / SIM interface upgraded?
I was told by T-Mobile that this is a known issue on the S4, and should buy a new phone (of course). I haven't the means, and am trying to get this fixed, as it's really annoying. Anyone have this same problem, and have any ideas?
Thanks,
-Rob
