Warranty Terms & BTRC NEIR Verification

Handsets designated with the Official National Distribution badge are imported or locally assembled under official authorization granted by the manufacturer and the Bangladesh Telecommunication Regulatory Commission (BTRC).

• Includes 12 months comprehensive warranty for parts and labor, provided directly by the respective manufacturer service network (e.g., Samsung Bangladesh, Xiaomi Service Center, Vivo BD, OPPO Care).
• Includes standard manufacturer battery and charger warranty (typically 6 months).
• Customers may present their official OASIS sales invoice at any authorized service center nationwide.

To offer regional flagship variants not officially distributed in Bangladesh (e.g., Snapdragon variants, global camera trims, specialized gaming editions), OASIS imports authentic global units directly.

• 7 Days Instant DOA Replacement: If the unit develops any authentic factory hardware malfunction (e.g., touch digitizer failure, dead pixels > 3, cellular modem defect) within 7 calendar days of receipt, OASIS will replace the handset with an identical unit.
• 1 Year Service Warranty: Covers free technical diagnostic and repair labor at the OASIS Dhaka technical lab for 365 days. If component replacement is required (e.g., replacement IC, battery), only the cost of genuine parts is billed without labor markup.

In compliance with BTRC regulatory guidelines and the National Equipment Identity Register (NEIR), every handset sold on oasisit.tech contains an authentic, non-blacklisted, manufacturer-programmed 15-digit IMEI number printed on the invoice.

Warranty coverage strictly protects against authentic manufacturer defects. Warranty will be void under any of the following occurrences:

• Physical Damage: Shattered glass, cracked display panels, dented aluminum frames, broken camera lenses, or excessive bending.
• Liquid Damage: Water ingress, moisture corrosion, or triggered internal liquid contact indicators (LCIs), regardless of manufacturer IP68 rating.
• Unauthorized Modifications: Bootloader unlocking, custom ROM flashing, root modifications that brick the boot partition, or repair attempts by uncertified third-party technicians.
• Tampered Serial/IMEI: Altered, defaced, or missing IMEI labels, or mismatched system software IMEI.
