Interesting..? I couldn't find a definitive answer when I did a search on supported networks; but several results did mention Android 10 and above and also very little on Apple/ios?... Strange. If you do want to try visible for a month I can give you a referral code for a $5 month unless you already have one. Let me know.
Do not want to sound like a broken record, but have you tried to contact visible customer support? Wonder if they could answer the question for you rather than 'trying' the service?

Customer support was the first thing I tried. Visible requires a IMEI #, which I don't have since my new phone hasn't arrived yet. Very frustrating system that I can't get by the automated system to ask a simple question. Guess I will wait for the phone to arrive so maybe I will be able to finally "Chat" with a human.
People ask me why/how is Visible so cheap (skepticism)? Well... when you don't have physical stores or a call center it really helps keep costs down. I have found that after I have my sim card installed I really don't need any help from Visible staff. With that said I don't see many benefits to eSIM??... That's my skepticism..
