Chosen Solution
I dropped my phone last night, and now it thinks it doesn’t have a sim card. How can I fix this? I’ve tried restarting it, but it cannot make calls, texts, or go online.
if the sim card is not reading, there is a high likelyhood something got damaged in the drop. either the sim reader itself, or, more likely, the logic circuit for the sim reader. if you replace the sim tray, and it doesnt fix the issue, then the logic circuit is failing, and that would need to go.
I solved this same issue, this might work for you too. Shut off your phone. Pop out the SIM card and place it on a thick piece of paper, use an exacto-knike to cut an outline of the SIM card on the paper. You can also draw an outline with a pen/pencil of the SIM and cut the outline. Try to be as precise as possible and dont exceed the outline, trim excess if needed. Then place the paper cutout in the SIM tray, place the SIM above the cutout on the SIM tray and pop it back in. Turn on your phone and you should get signal. If the SIM cant be popped back in, use a thinner paper, likewise, if this solution doesn’t work, test it out with a thicker paper/multiple layers of thin paper.
i just wiggle my sim card in and out and continue to turn my phone on and off
