My S8 does not forget the last network it was used on. I tried from forgetting the network, to hard reset and complete phone reset with cache clean. Since it does not forget, it also does not require phone to be restarted when I insert the Verizon sim card in it.
I have a strange issue and the way to fix it involves either my device forgetting the cellular network, or at least requesting me to restart the device when I insert the sim card. It appears Samsung/Google have become too smart (or collecting too much data).
Is there any way that I can achieve the above? Thanks

I brought a 8125 from ebay it had a cracked screen. So I had an PPC 6700 that had a bad radio so I took the screen out of it and placed it in the 8125. Everything worked great but when I turned it on it cam up with the message " Invalid or missing SIM card". I placed my Tmobile SIM card in I turned on the device and it reads the same thing. I read all the posts that I can find about this and they really didn't have much about it. I noticed that its searching for the network buy looking at the signal indicator but I also noticed the the led to sho that the phone was on doesn't blink. On some of the posts that I read it stated that if someone put the wrong code in to many times that the phone will be "counter blocked". I think maybe thats what happened with the last owner of the phone did. I at first unlocked the sim with the sim unlocker thinking that was the problem was but it still didn't work. My question is if it goes in to the counter blocked mode does it prevent the software from unlocking the sim. My other question is what is the file's name that when you place a sim in the phone that it runs to enter the unlock code on the phone? I was thinking maybe if I run that file manualy that maybe it will get the phone out of the counter blocked mode and then I can try running the software unlock again. Things that I have done to try to get it to work was sim and cid unlock, flashed tmobile rom to the device checked the contacts in the sim holder to make sure they are touching the sim card. Any ideas?
Sounds like it may not be a software problem. If the device was legitimately software blocked, it would display that, instead of 'invalid/missing SIM'. If it's IMEI blocked, it would have accepted the SIM but been unable to connect to the network.
The problem is most likely either the SIM itself or the onboard SIM reader. Try obtaining another SIM card and seeing if the device will read it.
Hi, Just bought my phone yesterday. After unpacking and going through the tutorial, i am not able to use any of the phone features on my HD2.
In the settings menu there is a switch to turn on the phone functions but that seems to freeze and after pressing nothing happened.
Everything else works except the phone features.
Can any one help.
make sure you have the right network provider selected (auto or your provider) maybe trying to connect to the wrong one or since you have not installed anything yet you might as well try a hard reset
Apologies if this comes across as a stupid question but have you put the SIM card in the right way? From memory, it goes in backwards with the clipped corner pointing out.
Sim card old
Thanks for all your help.
I went to ask my provider why my sim card wasn't working and why the phone was running slow and crashing.
The reason why it wouldn't recognize is because the sim card is about 6 years old and it needed updating. The HD2 didn't recognize the old sim card.
It works perfectly now and I am so happy i picked the right phone
Thanks for all your help
Hello All,
I am using HTC touch for a while and would use different ROM versions quite often. Recently i put in the some ROM which event i don’t remember which one i started getting this error below. I checked and made sure that there is nothing in the SIM card i also put in the SIM in different Cell phone to make sure its blank. I also reverted the device to the Factory Image but still the same issue. There is no pattern on when i get this error it would some time come twice in 1 hour and some time it would be couple of hours. Once i get this error and select Ok my network will go to searching and often end up enable Flight Mode and then disabling it.
"SIM card full. The SIM card is full. You must remove some messages from your SIM card to receive incoming SIM messages."
Any pointers are greatly appreciated.
Thanks,
Jasjit
it will be necessary for you to call the carrier to locate a retail location near you that has a Cellebrite device... not all locations have one as they are quite expensive... using the Cellebrite it is possible to wipe/edit your SIM...
this happens sometime with my device also.
but in my case i just clean simcard and reinsert it.
may be u have faulty simcard or sim socket .
i have a g1 but it doesnt made the unlock code request.
and it show a message
NO SIM CARD have NO SERVICE.
the sim is working perfectly on another phone.
how can i check the sim card reader..?
or any tip....
no body...????? heeeeeeeeeeeeelp....
Go to Settings > Wireless Controls > Mobile Networks > Network Operators.
Select the new network, and you'll be prompted for the code.
Also (for your silly simple checks) ensure the sim card is inserted in the correct orientation.. the key on the sim needs to match the diagram on top of the sim slot.

Unless something's broken, it won't even be able to go in backwards. The key cut needs to be in the right place in order for the BATTERY to be installed.

Why so it is (my fault for never actually trying.. had someone say they tried backwards [and it failed] but they also previously opened the phone without the right tools and the plastic of the battery case was a bit of a mess..)
hi to all, thank you by your help.. but i still with the same problem.
1. the sim is install in the correct positions
2. if i try to search my network it show,,,
your sim card does not allow a connection to this network, and never ask for the sin network unlock PIN
3. i installed 3 or 4 diferents sim and the same history, doesnt asl for sim network unlick pin

i try all but noting...
hello, me too i try to use my but i can't when i put the sim card it always shows "no sim card in phone" now what can i do to display the enter code screen?
food for thought
Just curious, have you gone to Settings-Applications-Manage Applications and searched for Google Apps and cleared the cache.
I had a similar issue with the unlock screen and my calls never ring through, they went right to voice mail. I cleared the cache and that resolved the issue. Not sure if it will take care of the network issue, but give it a try.
any update about..???? no body know the problem..?
Yesterday I upgraded to a gs3 which came with a micro sim. I wanted to see if I could keep my old phone as a backup. Would the lte micro sim work in my non-lte full-sized-sim captivate/gs1?
After 3 trys i managed to properly align the micro sim in the full sized sim slot and it worked. But then the weird part. Without powering down the phone I plucked out the sim (possible because the micro sim is so small). To my surprise the phone did not give any error and both data and voice calls continued to work without a sim actually in the phone.
How was that possible? Further, what would have happened if I had booted up my new phone with the sim card that my old phone still thought it was using (I was too afraid to try)? Would both phones continue to work? Would they both ring when someone calls?

any sim should work as long as its activated and its the same size.
and no they both wont work, the phone that has no sim will show "no sim" upon reboot

Perhaps I was not clear. I removed the sim without turning the phone off and it continued to work. I know it should not, but it does. That is what I am asking, how is that possible? Does the phone only check for a sim when it boots, and from then on the sim is not needed?
Then what would happen if I boot up phone #2 while phone #1 still thinks that the sim card is in it.
I'm interested, try it and let us know what happens.

I'm not an expert, but I think all the SIM provides is a string of numbers that identifies the phone with a phone number. This is most likely cached in the device while it is on and it might not need the SIM card after it has already gotten the information. This might not pertain to all phones, maybe the Galaxy S3 was programmed slightly differently.
If you power down the phone and restart without the SIM, the phone will most likely ask you for a SIM.
It is an S1/Captivate that is working without a sim. And yes, when I reboot the phone it stops working. I'm not brave enough to try both phones at the same time. That seems like something that the phone company would notice.
I tried removing the SIM from my captivate while it was running, and for a short time it still showed signal. Soon after I got a message asking to put in a SIM and restart. I don't have an LTE SIM or microSIM to test with, but it doesn't seem likely that the cappy will continue to work without one. Or at least without starting with a regular SIM.

i Know that this is an old thread but i just wanted to say that with some networks, you can take the sim out and still use the phone locally. they only use the sim for international or roaming outside the country. thats what i got from Sprint before. i dont know about other networks
Pease cany any body tell me who can download apps frpm this software
