I do not think its a problem with your 4g ranges.
Those are too big to be blocked.
When you used your fathers phone, did you use all those extensions? Because that is the reason the creation fails.
If Instagram sees you are blocking too much they wonât let you create the account.
If you use your fathers phone without any extensions or anything it should work. Like a normal user would do.
You wonât be able to create many accounts thoughâŠ
yup, still works and a good method. But really, did you saw anyone buying empty, 1month old accs for 2-3$? Thatâs really expensive
