SIM card
My phone’s data isn’t working anymore so I canceled the company and got rid of the SIM card but where you check what carrier you have it still said searching. I’ve put in a new SIM card from another company but it isn’t doing anything. I’ve tried turning it off , restarting it , resetting network settings, cleaning where you put the SIM card, everything. I also can’t update it which I think is the problem but it says I’m not connected to the WiFi when I am and I have good WiFi. Help.

    "...it says I’m not connected to the WiFi when I am..."

    If it says you're not connected, how can you know that you are connected? And why are you using WiFi for your cell phone? Why not use the cell connection instead? What does your cell carrier support group tell you about using their SIM card in that phone?

    With unlocked phones, you can always switch your phone service between different phones as easily as popping out the SIM card and moving it. ... In contrast, only SIM cards from a specific cell phone company will work in its locked phones.

    That means you need to get one that your service provider supports.

    In the US, Sprint, Verizon, and US Cellular use CDMA. AT&T and T-Mobile use GSM.

    Most of the rest of the world uses GSM. The global spread of GSM came about because in 1987, Europe mandated the technology by law, and because GSM comes from an industry consortium. What we call CDMA, by and large, is owned by chipmaker Qualcomm. This made it less expensive for third parties to build GSM equipment.

    Your phone is probably locked to a specific company network, like Todd suggested.

    If the SIM is not accepted by the device, I doubt updating it will make any difference.

    Since the previous SIM stopped working, and now you can't even to connect to WiFi (If the phone says you are not connected, you are most likely not connected), then the device might be damaged.

    I would try resetting it to factory settings, and if that doesn't solve it, would consider getting a new device.
