As the tittle sais, i was trying to create an instagram account and it is not possible without a phone number. Same with discord. Obviously i dont want to provide mine. Any working solutions to bypass this? not looking for alternative private service, i already use them.
You just need a number that doesn't show up as VoIP, it doesn't actually need to be a SIM card. So if you have a Google fi number, you can use Google messages to access it over the web, even when the phone is off. Because when Carriers look the number up it doesn't come over as VoIP it shows up as an actual mobile number.
You can get numbers from twilio in countries that don't report voip status. That also works.
If you need a number in a country that does report VoIP status, you can use the phone number providers I posted in a different comment in this thread, to get a temporary number that is not VoIP, and receive your SMS verification
