Hi!
I have been trying to download a list of phone numbers that are subscribed to our notifications. I downloaded the csv list to see how many active numbers are there.
Then i have decided to devide the initial list in random groups of 1K of phone numbers to send them sms.
But when i started downloading those groups og 1K it didnt download and just said there duplicates that can't be uploaded to the new lists.
Now I have deleted the initial list and cant upload any numbers anymore because of duplicates.
How do i create lists of 1K phone numbers thet were already in the database but i cant downloan them now? Problem is I cant even do the segmentation, because phone number is all i have.
