I'm really surprised that you have such a high rating here, when everyone is actually complaining about this company. I'm not going to say my story, but I will advise you to check why they don't have a google profile (so no-one can share their frustration, obviously), and trustpilot - is flooded with their own reviews, but if you check sites like reddit (where Unitel doesn't really have any power to delete or influence the comments) - you will see their real reviews.
Recommendation: Stay away.
