I use Globacom for my food business calls and data, and everything works fine. Network coverage is strong even in the mainland where I sell, and the data packages are reasonable for my pocket. My only small complaint is when I went to their Ikeja office last month to sort out my billing issue, I waited almost 2 hours before someone attended to me. To be fair though, the lady that helped me was polite and fixed everything well. Overall I'm satisfied with the service, no be lie.
