Your file should be in Excel (.xlxs) or .csv format.
If you have more than one phone number per line (row), you will need to run the file multiple times. For example, if you have three columns of phone numbers, you will need to run the file three times. Each time you run the file, you will have to specify which column contains the numbers that you want to use for that run.
Don't forget that, for Carrier247 (International), you will need to include the country code before the rest of the number.
The maximum file size that can be uploaded is 20 Megabytes.
