MTN XtraByte is a newly introduced service that lets eligible active prepaid customers borrow data on credit when they run out of data while browsing and pay back on their next recharge.
I see this as a welcome idea knowing that similar service was launched by MTN some years but was only for airtime (call cards) so giving its subscribers the option to borrow data is a good innovation because many people now prefer to have data on their Smartphones than having call airtime. Am one of those that prefer data to airtime. I don't know about you.
Interesting thing about this offer is that you can borrow airtime through MTN XtraTime, also borrow "data through XtraByte" as long as you are eligible for the services. So both voice and data options are there for you.

IMPORTANT THINGS YOU NEED TO KNOW ABOUT MTN XTRABYTE DATA
1. You can borrow data once you are eligible
even if you have an existing airtime loan that
you are yet to pay back and can and also
borrow airtime once you are eligible even if you have an existing data loan that you are yet to pay back as long as you are within your credit limit.
2. The XtraByte data will be loaded into a
special XtraByte account and not the usual
normal data account.
3. To pay back the borrowed data, MTN will
deduct your airtime when next you recharge on that line (equivalent to the price for the
borrowed data bundle) it can also be deducted
via Share N Sell or any other means For instance, if a customer owing N110 XtraByte does a recharge of N400, the N110 owed is first deducted from the recharge, then N290 will be loaded into the customer’s main account.
4. You are allowed to borrow XtraByte data as many times as possible as long as you has no outstanding XtraByte payment and is eligible for the service.
However, you have to pay up all outstanding
XtraByte data to be eligible to use the service
again.
