LTE roaming charge

<p>I've read an article where research was done . Where the top cell networks had airtime put into the same phone and only wifi was used for one month. Turned out that all other cell networks had same balance as startup only MTN balance for depleted . MTN charged for LTE roaming where the device search for LTE network although mobile data was turned off . This article was published in the Sunday Tribune Magazine dated 30 July 2017. So as a contract subscriber whose data mysteriously disappeared now I know why . Only MTN charged for this service not any other network. Your airtime balance slowly decrease due to MTN charging for this . How will you make this up to all your loyal subscribers. I'm saving this article as MTN said that it will adjust its prices. And they were supposedly not aware that there competitors don't charge for that . </p>
