I just purchased a Techno L3 android phone for my dad, who loves to surf and read online. within the first one week of use, he complained that the phone isn't data friendly or data economic. He's an MTN subscriber and wouldn't wanna change that for any other network. Please which data plan would u suggest or recommend for him. he currently surfs via his airtime. I don't know much about mobile data plans. Your suggestions are most welcomed.
