Question: how to transfer data from airtel to another airtel line?
Answer: Data Me2U (aka Data Share): You can “share” or "transfer" from the data allowance of an already purchased data bundle to another customer. For example, if you have purchased a 1.5GB Monthly, you can transfer 100MB to another customer. To share/transfer data, simply dial *141# and select the option for Gifting or Me2U.
