Resolved Question

Samsung GT-S5600/Galaxy Mini2

When I changed the SIM card for another network provider it is no longer recognised.( Insert SIM error message)

(a) I have tried 4 different cards including the original and they all raise this SIM Missing error message
(b) I have cleaned the PCB pins and they appear OK
(c) I tried the trick of packing out the SIM card with a piece of paper to make a more adhesion with the pins
All of these failed
However before this saga I used Keis to update the firmware which went OK. It wasnt until a few days later when I wanted to change the SIM this error occurred
Also now Keis throws up this error " failed to retrieve device information" when I attempt to get it to talk the the Samsung
The phone works 100% using my Wi-Fi network
I wonder if its possible to uninstall the firware update, trouble is I cant get Keis to talk to it any longer
Help !

This has prior discussions when

It sounds like the phone was locked. TracFone, ATT and others are locked and do what you noted. Too bad we didn't know what carrier you got this from.

Samsung Sim

Firstly I have the model of the phone incorrect it should read "GT-s6500"

The carrier is T mobile in the UK
The problem only manifested itself when I took out the original T Mobile sim and inserted a Virgin sim in order to change the carrier
This was not accepted, so I went back to the original T mobile SIM and now it wont recognise any SIMs I insert

It sounds like it needs repair now. Try a full reset as well as heading to a Tmobile counter to get it back in service.

I don't see any notes online of how to provision this one but the no sim sounds like a hardware failure. Now I don't usually point out or share I've found folk forcing the sim into the wrong socket or direction but try these sims in another phone as a test to see if the sims are OK.

I had a long conversation with Samsung UK today and the technician had never heard of such a problem.
He has arranged for me to be supplied with a post paid box in a few days so it can be returned to them for investigation.
He said there would be no charge, but I will check on this before I send it back
Its not worth spending £££`s on it

I also spoke to T-Mobile, but as I was at the end of my contract and within the "upgrade" period they would supply me with a new phone.
Trouble is that would start up another 24 month contract and the reason for this SIM change was to get away from EE as the signal locally is very poor

Aha. My bet is the phone was locked.

That's why I would be testing this sim on another phone. Frankly I cringe when folk tell me they never heard of such a problem. Too easy to find this on Howard's Forums or the web today.

Cell carriers are all over the map on deals, renewels and such but this sounds like a locked phone. You can get many answers about that such as "I don't think it's locked" but having been around the block a few times I'm wondering if it's locked.

There's also bugs galore in these phones. Don't get me started. Next month I'm going with a GSM move but here, it's different than there. Wish me luck.
