I have just singed up for the auto-refill option for my feature data package (for my smartphone). I understand that it will auto-refill in 30 days by taking the money out of my account balance. My question is will I loose my data balance (which is quite high) if it is renewed on the 30th day as scheduled....or should I refill it myself on the 29th day? I don't use a lot of data at this point in time and that is why I have a large reserve of data built up. However, I do not want to loose any of my balance in case I really do need to use a lot of data in the future. Any suggestions or clarifications would be appreciated.
You might. It's kind of risky to set up auto renewal with data remaining on your data package. I would suggest to manually refill your data package yourself on the 29th day. I would rest much more assured rather than having to worry about if the existing data balance will be kept or forfeited.
