IG Ban with Real Number

To check my account I bought 10 o2 sim. massplanner and use an iPhone to receive the verification text message.
3 account for sim.
all right for the first 10 account, now also changing sim other accounts are banned (1 for proxy accounts). Solutions?

it could be due to:

-proxies
-your settings
-your account provider
-is there a link in the account bio?
-do you use spamwords
-did you copy all your accounts so they are the same?


a lot of factors to consider do you have any others account that are running successfully?

maybe your phone number or proxy flagged
