OEM unlocking option disappeared after inserting Cricket SIM Card

[OutNumbered]

I have a Samsung Galaxy S9 GSM + Verizon Unlocked device. The oem bootloader was in the developer settings at first, but i inserted a Cricket Sim Card and on the screen it said "Changing Carrier Settings" , and it rebooted and ever since then for about 2 months now it always has the Cricket Startup Image & OEM unlocking has been tooken off the settings . I've tried everything. Please assist me

Try putting another sim such as the one before you inserted Cricket sim. See if this will make OEM unlocking appear again.

Trust me, i have literally 15 different sim cards that are different carriers (don't ask) . Nothing seems to work. I have a laptop but something is wrong with the drive so i can't root it. I factory reset it and it still has the same boot image .

What about flashing the firmware(without sim in it) to the one that came with the phone or to an unlocked model which allows oem unlocking?

Can you please explain how? I don't have root access or access to a laptop, so is it still possible

Search for XDA developers website and pick a section with your model and post your question about flashing in an appropriate section. Users will help you out.

I recently received a sim card from truconnect and it says sim is locked. What do I need to do

You can Google the SSID codes for your type of device and it should give you a code to type into your phone dialer
