Step-by-Step: Getting a 4G Connection in Sri Lanka

Sri Lanka's mobile market is competitive. Three main operators offer 4G: Dialog Axiata, Mobitel (SLT), Airtel. Here's how to get connected.

1. Check Coverage at Your Location

• Dialog: dialog.lk/coverage
• Mobitel: mobitel.lk/coverage
• Airtel: airtel.lk/coverage
• Or ask neighbors/colleagues which works best.

2. Choose a Plan

Compare data allowance, validity, price, throttling policy.

Postpaid plans offer better per-GB value for heavy users.

3. Get a 4G-Ready Device

• Phone: Must support LTE Bands 3 (1800), 8 (900), 20 (800) — all three used in SL. Check GSMArena.
• Router/MiFi: For home/office. Dialog 4G Router, Mobitel MiFi, generic (Huawei, TP-Link) Band 3/8/20 compatible.

4. Acquire & Activate SIM

• Tourists: Buy at airport (Dialog, Mobitel kiosks) or city outlets. Passport + photo. Tourist packs: 10–20GB, 30 days, ~Rs. 2,000–3,500.
• Residents: Any dealer. NIC + photo. Register via SMS/app.

5. Top Up & Subscribe

• USSD: Dialog: #678# | Mobitel: #170# | Airtel: *123#
• App: MyDialog, MyMobitel, Airtel Thanks.
• Reload: Scratch cards, eZ Cash, Genie, FriMi, bank apps, dealer.

6. Configure APN (Usually Auto)

If no data: Settings → Mobile Network → APN → New:

• Dialog: dialogbb / dialog4g
• Mobitel: mobitel / mobitel4g
• Airtel: airtelgprs.com

7. Test & Optimize

Speedtest. If slow: toggle airplane mode, restart, check band lock (apps like Network Signal Guru), relocate router near window.

Tip: Dialog generally has widest 4G coverage; Mobitel strong in towns; Airtel cheapest. Dual-SIM phone = best of two.
