Few facts to add to the discussion.
Dialog 4G LTE is not actually from Dialog. It is from Suntel. Honestly speaking, I have very good expereince with Suntel. It is a company that helps to shape the customer service for telephone operators in Sri Lanka. There was a time that SLT was dominating the field and I remember how harsh they treated the customers especially me who was in a very young age. I then decided to buy a Suntel line (I was among the first set of customers those days) and I came to know how customer service should be in a company from them. That type of high quality service had been given to me. Later on I came to know that due to competition they couldn't service with private users so they started to aim mostly at corporate customers.
When Dialog and Mobitel announced on their 4G LTE packages, I came to know that the Dialog one is far more better than Mobitel in terms of technology used. So I went with them. I knew that Dialog customer service isn't that good anyway. However, for an online billing issue, I called them and came to know the full story from an agent. According to him, the who engineering part is done and maintained by Suntel. Only the billing, customer service and advertising part is done Dialog.
So in conclusion, Dialog 4G LTE = Suntel
I have used Mobitel 3G broadband and the quality was very good. However I do have to tell you that Mobitel customer service is the worst I have ever seen in this country. I think it should be 100% privatised and left out to competition
Airtel 3G Broadband, I used this too. I highly advised to stay away from this completely. Worst technology + worst customer service.
SLT has the lowest cost per GB
This is not true.
Entree 1.5GB Rs. 499, Rs. 332 per GB
Web Starter 5GB Rs. 740, Rs. 148 per GB
Web Pal 8GB Rs. 999, Rs. 124 per GB
Web Family 20GB Rs. 1490, Rs. 74 per GB
Web Family 25GB Rs. 2690, Rs. 107 per GB
Web Family 35GB Rs. 4890, Rs. 140 per GB
* I'm not going to mentioned the free GB they have mentioned which I think is an effort to trick the innocent people of this country. One of the worst strategies I have seen from a fully government owned company.
Here comes the Dialog 4G LTE rates.
Lite 25GB Rs. 1490, Rs. 60 per GB
Ultra 60GB Rs. 3900, Rs. 65 per GB
I think you are clear on the fact now. As far as I know, Dialog 4G LTE is the most convenient and cost effective internet package in Sri Lanka. I'm very happy about the performance of the line quality. However if an official is seeing this post, I would like to ask them to further decrease the router fee. If they can do this, I'm sure they will be able to kick SLT off the race. As said about Mobitel, SLT must be 100% privatised and let to compete with the private sector. This has become a white elephant to the country. At least the Billing and customer service must be privatised. Otherwise even thought it is government owned, it will never do anything useful for the people of our country.
