Sim Card Icon with Exclamation Mark on Samsung Galaxy Y Phone

[Anonymous]

Hi, I bought the Samsung Galaxy Y GT-S5363 phone back in March this year. I put my SIM card that was in my old phone into the Samsung Galaxy phone but every time I turn it on I get a full signal but the SIM card icon keeps displaying an Exclamation mark on it. I have took the SIM card out and replaced it with a new one and I still get the same problem. I took it into the O2 shop today and they did another sim swap and once the sim swap was completed, I still got the SIM card icon with the explanation mark. Does anybody know what the problem could be? Thank You xx

Is the phone locked to a different network other than O2? Do you get any other carrier branding when you start the phone or are there any other network apps installed?

I asked the same questions in the other thread. Sounds locked.

It's not locked to any other network apart from O2. Every time I start the phone with my O2 SIM card in, I still get the SIM card icon with the exclamation mark on it and there are no other network apps Installed on it. When I check the phone status the network says 02.

Where did you get the phone from?

I bought it from an O2 shop.

Take it back and get it exchanged for a working one
