Should I delete the number after PV?

Hello, right now I have 50 instagram accounts in Followplanner software. I do not receive blocks, usually I only get about 2 PV a day and I check with smspva.

Today I was hit by a PV. But unfortunately the instagram did not let me change the number. Result: I lost my account.

My question is: Should I delete the number after PV?

Sorry for my english.

Yes if you will not have access to that number any more or use real sms service that you get get the sms code again every time

Why not but real SIM card.
For 50 acc you will need 20 SIM card 1 SIM/2-3 acc and your acc will be much stable and safe.
And is one time cost.

Use EV instead of PV
