Hello people, I'm trying to use a Claro sim card on my Personal phone (both carriers are argentinian), but can't get it to work.
The Claro card works on other phones. Mi xt925 is running CM 10.1.3 and the correct baseband (100700.220.62.33p).
It even showed me the gsm menu from Claro but no option worked, and still have no signal and get "Network not available" error.
I get something about the sim can be registered in Claro Argentina (as I said, the sim is working with no problem on other phones) when tryng to choose network.
I already have and unlock code, and don't have another sim (from a different carrier) to test it.
Is there anyway to force the phone to ask for the code?
EDIT: In case someones gets to this post, I fixed it going back to stock rom by using http://forum.xda-developers.com/showthread.php?p=38190729.
I put my sim card in and automatically asked me for the code.
so i have this s6 verizon phone that was given to me. i use tmobile network and put the sim and made the APN changes for data. but i cant get rid of the " not a verzion sim card" message in the alerts.. is there a way to disable that?
I purchased a S6 on EE a week ago. Has been working fine with an ee sim, however I have not made any calls or texts yet, just using the phone for Internet on wifi etc.
I have a regular three sim which I would like to use so I have trimmed it down with scissors and this made me cut part of the gold contact bit off (I read online this shouldnt affect the sim).
I'm guessing this phone is locked as when I insert the sim it detects a new sim has been inserted, it makes me restart too. Upon booting up however it says no sim card/ emergency calls only however I see a solid connection. I cannot make any calls as it says not registered to a network or something.
Now my question is that is the phone picking up the sim card? If yes why is it not prompting me with a sim unlock code screen? Secondly is my phone not detecting the sim card at all? Is that the reason why I am not prompted with a unlock code screen? All help is appreciated. Thank you.
Go onto settings, then onto Mobile Networks, then Network Operators, then Search Networks then click the Three carrier. It will take a few mins to search for all the networks so do not back out.
Hi, I recently got an Infinix HOT 3 LTE. It's a really great phone, but I have a problem with it, my 3G SIM card isn't working properly.
When I insert it and start the phone, the card is detected, I enter my PIN code, then when I try to make a phone call it says "Cellular network not available". I tried switching the SIM card slots, both didn't work for my card. Then I tried to change the network provider manually and all and I also tried changing other cellular network options over and over again but nothing worked, I also tried switching airplane mode on and off. I got frustrated with this problem and I decided to factory reset my phone, but the problem was still there. After that I tried using someone else's 4G SIM card, and it worked, so there's no problem with my phone or SIM slots. My 3G SIM card is fine I think, it works on my old phone, as well as others.
Please help if you can.

Greetings and welcome to assist. Are you sure the phone is compatible with your carriers bands? If you are sure try asking your network provider for a new sim
Good Luck

hello, I have a Samsung s6 edge+ from sprint (SM G928P). It was working fine with all the carriers in my country (El Salvador) But after a Reset, it did not recognize any sim card. It shows a message saying to insert the UICC sim card provided by my carrier.
The weird thing is that, sometimes, it barely gets signal, but no data. This is just for a minute and then, no signal with any carrier.
Is there a solution? I have the MSL code in case I can use it. I tried to activate global mode , but it did not work.
thanks a lot in advanced
