If you’ve been watching the Sri Lankan internet space recently, you know things are heating up. Hutch just disrupted the market with their affordable fiber options, but the giant has awakened. SLT-Mobitel has revamped its unlimited lineup, and for the first time in a long time, “Unlimited” might actually mean Unlimited.

Whether you are a heavy downloader, a work-from-home pro, or just tired of counting GBs, here is the breakdown of SLT’s new unlimited ecosystem for 2026.

1. The Game Changer: “Fibre Unlimited Home”

This is the package everyone is talking about. Previously, SLT’s “unlimited” plans (like the Flash series) had daily limits (e.g., 10GB/day) before slowing down.

The new Unlimited Home changes the rules. It gets rid of the daily limit entirely.

• The Speed: Flat 100 Mbps Download / 50 Mbps Upload.
• The Data Cap: None. (True Unlimited).
• The Price: Rs. 5,900 per month (excluding taxes).
• Why it wins: You no longer have to worry about “finishing your daily 10GB” by noon. You get a consistent 100 Mbps connection 24/7. For most households streaming Netflix in 4K or downloading games, this is the sweet spot.

Pro Tip: With taxes (approx. ~23.5%), your final bill will likely be around Rs. 7,300 – 7,500.

2. The Premium Tiers (For the Speed Freaks)

If 100 Mbps isn’t enough for you, SLT has introduced higher tiers for power users.

Package Name	Speed (Down/Up)	Monthly Rental (Excl. Tax)	Best For
Unlimited Home	100 Mbps / 50 Mbps	Rs. 5,900	Families, Streaming, WFH
Unlimited Plus	200 Mbps / 100 Mbps	Rs. 9,900	Large files, 4K Video Editing
Unlimited Twin	200 Mbps / 200 Mbps	Rs. 14,900	Content Creators (Symmetrical Uploads)

3. The “Old Guard”: Flash Unlimited

You might still see the “Flash 10” and “Flash 25” packages.

• Flash 10: Gives you 10GB/day at max speed, then throttles to 1 Mbps.
• Flash 25: Gives you 25GB/day at max speed, then throttles to 1 Mbps.

The Verdict: With the arrival of the Unlimited Home package (100Mbps flat), the Flash 10 package has become largely obsolete for most users. Why deal with a 10GB daily limit when you can have 100Mbps all day long for a similar price?

4. No Fibre? No Problem (SLT 4G LTE Unlimited)

If you are in a rented house or an area without Fibre coverage, SLT’s 4G routers offer a different kind of unlimited. These are “Speed-Capped” plans. You get unlimited data, but the speed is fixed.

• Unlimited 2 Mbps (~Rs. 2,950): Good for WhatsApp, Facebook, and light browsing.
• Unlimited 4 Mbps (~Rs. 5,150): Can handle standard YouTube streaming (480p/720p) and Zoom calls.
• Unlimited 8 Mbps (~Rs. 7,090): The best 4G option for HD streaming and multiple users.

5. The Secret Weapon: Night Data

Don’t forget, if you are on a standard “Anytime Data” package (not the unlimited ones above), you still get Free Unlimited Data from 12:00 Midnight to 07:00 AM.

• Hack: Schedule your massive game downloads or backups to run at 1:00 AM. It costs you nothing!

Final Thoughts: Which One Should You Pick?

• The Best Value: Go for Fibre Unlimited Home (Rs. 5,900). It is the most balanced package for a modern family. 100 Mbps is fast enough for almost anything, and the lack of a daily cap is liberating.
• The Budget Choice: If you are on a budget and don’t need speed, the 4G LTE Unlimited 2 Mbps is a cheap way to stay online 24/7.
• The Professional: If you upload videos to YouTube or send large files, the Unlimited Twin offers rare symmetrical upload speeds (200 Mbps Upload).
