Hello and thank you for using Q&A,
maybe the SIM-Card is broken. Are you able to try another SIM-Card in your Samsung Galaxy S4?
Kind regards

My sim new. Brought only 1 month before.other 2 sim card differant provider working fine.only my new vodaphone have error.
If all other SIMs are working, your SIM is broken.
Maybe you can send it back to Vodafone.

Hey all
One of my friends bought for me a Samsung Galaxy J5 6 from Germany and I am out of Europe and as I checked there is a limitation for European sim cards only.
I have not access any European sim card so I can not make a test call.
I tried to find a way to unlock and I found unlockunit dot com now I have two questions:
1 - Is this web site real and can I trust it?
2- For 'Galaxy J5 6' should I select 'Galaxy J5 2016'?
3- It asked me about Network of origin. I do not know the origin network. I just know he bought it from Germany. Is anyway to figure out?
i unlocked my wife´s phone with a 5 minuts phone call with a sim from teh original location as per samsung orientaions (via live chat) i think the best option if for you to get your hands in a german sim somehow do you know anybody in DE that could buy a sim and send you one?

S6 Edge Plus Sim not detecting

Hello everyone,
Having a few issues with a s6 edge plus i recently just purchased from a person on eBay. He said that he put the sim card in the wrong way and got it out and now it doesnt detect the sim card. Any ideas how i would be able to fix that? Get Error 'Not Registered on Network', Should i replace the sim card reader or any tips i could try to fix it before i do that.

If knox is not tripped it means you are on stock rom and no manipulated device so yeah hardware issue got to nearest service centre
Probably, Sim reader is damaged. But to make sure not to overcomplicate the matter, check with different sim card. S6E+ is using micro sim and your card in question may be damaged itself. But chances are, your SIM reader is damaged. Are you able to make emergency calls?

SIM not found (only specific one)

Hi
I have a really strange problem and havent found a solution for this:
My son has a S3 Mini and recently got a new Galaxy S4.
Because the S3mini doesnt use the micro-sim formfactor I ordered a new micro-sim from my provider (Bob-Austria).
I have rooted the S4 and installed the Omega Rom V40 (same problem with V42)
I activated the SIM card by phone and put it in the new S4, but the S4 doesnt recognize the sim, it always says "no sim found".
But the really strange thing is: The new SIM card works fine in my Galaxy S5!! AND the SIM card from my S5 works fine in the new S4!!
(I tried a third SIM from my wifes S3 and this one works fine as well in the new S4)
Could this be a modem problem ? All SIM cards are from Bob, only that the one in my S5 is a year old. I have tried two different modems (one recommended from the omega download site)
thanks for your help
regards
Erich
