Question: how to know if someone is using your data on glo?
Answer: To do that, you can text the word 'List' to Glo's number, 127. Remember this number, as you will be using it quite a lot for activating and deactivating Glo products and functions. Alternatively, you can execute a USSD command to see your share list. Just dial *127*00#, and the list will appear on your screen.
