Link3 vs AmberIT vs Dot Internet vs Carnival: ISP Comparison
By BDIX Editorial · Updated
Link3 Technologies Ltd, AmberIT, Dot Internet, Carnival / Nagordola and Circle Network are compared here on the facts that decide the choice between them: BTRC licence category, coverage, networks, contact details and published internet packs. Between them these providers publish 40 internet packs, read live from the ISP directory as the page renders.
Two facts decide this comparison, not the price lists. The Coverage row says which of these providers can reach your address, and in Bangladesh that is what rules a provider in or out. The BDIX server row says whether the connection comes with local content: Link3, AmberIT and Dot Internet each run a server recorded as reachable over BDIX peering, while Carnival and Circle Network are recorded as reachable on their own network only. All five publish fixed-line packs, so the tie-break between the three that peer is coverage and price rather than who runs a server.
Link3, AmberIT, Dot Internet, Carnival and Circle Network are the fixed-line providers Bangladeshi buyers compare most often. This page puts their BTRC licence category, coverage, contact details and published packs side by side, together with the BDIX server each one operates and who can reach it.

The Two Rows That Decide It
Most ISP comparisons in Bangladesh are decided before the price tables are read, and these five are no exception. The Coverage row above is the first gate: a provider that does not serve your area cannot serve you, whatever its packs cost, and the five records here describe noticeably different footprints. Read that row against your own address before reading anything else on this page.
The second gate is the BDIX server row, which is the one figure on this page that no other kind of comparison site can show you. Three of these five providers run a media server that is recorded as reachable over BDIX peering. Two run one that is recorded as reachable on its own operator's network only. That difference is not a quality judgement about the providers, it is a statement about routing: a local-network server is one you can reach when that operator supplies your line, and a BDIX-peered server is one that a wider set of connections can route to.
What Each Of The Five Actually Is
- Link3 Technologies is the oldest of the three that peer into BDIX alongside AmberIT, and it runs Link3 FTP, also published as CineHub. Its published packs start lower than any other provider on this page and stop lower than the other two that peer, so it reads as the entry-level choice of the three.
- AmberIT runs AmberIT FTP and publishes the largest number of separate packs here, spanning the widest price range on the page. Its coverage record describes Dhaka plus nationwide enterprise service, so a reader outside Dhaka should treat the Coverage row as the question to settle first.
- Dot Internet runs D-Flix and publishes the highest speed ceiling of the five, against the highest entry price on the page. Its coverage record is written as a hedge rather than a coverage statement, which is the honest reading of it: confirm your own address with the provider.
- Carnival is the only provider here in the Divisional licence category, though its coverage record lists Nationwide. Its server is recorded as reachable on its own network only. That category and coverage pair is the one to check carefully if nationwide reach is what you need.
- Circle Network runs Circle FTP, the largest BDIX movie server by catalogue volume, and publishes the fewest packs of the five. Its record describes nationwide reach via BDIX peering, and its server is recorded as local-network only.
Why The Reachability Split Is Worth More Than The Price Gap
The price difference between these providers is real but small next to the reachability difference, because the two do not fail in the same way. Choosing the slightly cheaper pack from a provider that cannot route to a server you want means buying a connection that will not open it. Choosing a marginally dearer pack from a provider that peers means the local content arrives with the line.
That is also why the three that peer are not interchangeable with each other despite similar headline speeds. If your reason for comparing these providers is BDIX content, the peering column is the shortlist and the price column is the tie-break, in that order. If your reason is ordinary internet for a home or an office, coverage is the first gate and the BDIX row matters much less.
Reading The Category Column Correctly
The BTRC category is a licence class, not a coverage promise, and this page contains a good example of why that distinction matters. Four of the five are recorded in the Nationwide category. Carnival is recorded as Divisional while its coverage field lists Nationwide reach. Neither figure is wrong, they answer different questions, and the one that decides whether you can subscribe is coverage.
Treat the category as a signal of scale and the Coverage row as the fact. Where the two appear to disagree, the coverage is the one worth confirming with the provider directly, which is also where you will find current pricing that has moved since the pack table was recorded.
How To Choose
Work through the page in this order. Start with Coverage and cross out anyone who cannot reach your address. Then, if BDIX content is why you are here, keep only the rows where the BDIX server column shows a server that is not restricted to its own network. Among what remains, compare the pack tables for the speed and price tier you actually want, and check membership and support details on each provider's own page before you commit.
If nothing survives the first gate, the answer is not a different provider on this page but a different shortlist, because no amount of price advantage makes a provider that does not serve your area into a choice.
Why These Figures Can Be Trusted To Be Current
Nothing in the tables is typed into this page. The licence category, coverage, contact details, established year and published packs are read from the ISP directory as the page renders, and the BDIX server row is read from the server records, so a provider that adds or drops a server, or changes a pack, appears here corrected on the next page load. This page is edited only when the reasoning changes.
