Not getting texts from others anymore

I switched about a year ago. I was receiving texts from others even those with the same company and different companies as well.

It’s been months now but I did receive texts from my friends and family with androids who have US Cellular, Verizon, Cricket, AT&T and they used to get my texts before as well.

now I can’t receive their texts anymore which now I have to contact them through social media or WhatsApp, even international texting is the same as well. 

I have turned off IMessage and reset the network settings and as well did reset my phone as well. I turned on and off my phone multiple times, did the airplane mode many times as well. 

I went to my local store and all they told me was to contact Apple Support which I haven’t done yet. I wanted to ask here first and see if anyone can help! 

I can text back and forth with my husband who has an android but I’m assuming I can do that because he is on the plan as well.

I have IPhone 13 Pro
