The Tecno Spark Slim is one of the slimmest phones Tecno has ever made — a 5.9 mm-thin body with a 6.78-inch 144 Hz AMOLED display, a 5160 mAh battery and 45 W charging. It was announced on 2 September 2025 and released in October 2025.

- One of the slimmest phones around: at 164.2 x 75.9 x 5.9 mm and 156 g, it is one of the slimmest curved phones at 5.93 mm thick.
- Centre punch-hole selfie camera and a horizontal pill camera module with two lens-style circles — the camera itself is single; the module also carries the status-light LED on the back.
- Under-display optical fingerprint sensor for unlocking.
- IP64 dust and water resistance (water splashes) and MIL-STD-810H compliance* — *the standard does not guarantee ruggedness or use in extreme conditions.
- Fiberglass back with a status-light LED on the rear.

Price in Pakistan
The Tecno Spark Slim is priced at an expected Rs. 43,999 in Pakistan. MobileDokan lists no price rows for this phone — only the glance “Expected price ৳30,000” (which converts to about Rs. 66,999), which is not a sourced price and sits above the Pakistan market. The Pakistan price is a seller- and PTA-dependent range of Rs. 43,999–52,999: zmobiles and mymobile agree on the range, whatmobile’s headline is “Expected Rs. 43,999”, and hamariweb lists Rs. 43,999. The price entered for this listing, Rs. 43,999, is the bottom of that range. PTA status is not yet confirmed — confirm via DIRBS before buying.
| Model | Price |
| Tecno Spark Slim | Rs. 43,999 |
| Display | 6.78″ AMOLED, 144Hz |
| RAM | 8GB |
| ROM | 256GB |
| Released | October 2025 |
Buying in Pakistan
- Check the IMEI and the exact model number (KM7k) before paying.
- Confirm the warranty with the seller.
- Confirm PTA status via DIRBS — PTA status is not yet confirmed for this phone.
- Check the price before paying — the range spans Rs. 9,000 by seller and PTA status.
- Do not confuse it with the Pova Slim (Dimensity 6400, dual 50MP, 5G), the Spark 40 Pro (Helio G100 Ultimate, single 50MP, 5200mAh) or the Spark 40 Pro Plus (Helio G100 Ultimate, dual 50MP, KM7).
Final Verdict: A 5.9mm-thin AMOLED phone with a 5160mAh battery, priced by the seller rather than by Tecno
The Tecno Spark Slim is a design-first phone: a 5.9 mm body, a bright 144 Hz AMOLED display and a 5160 mAh battery with fast 45 W charging are genuinely hard to find at this price. The trade-offs are a single rear camera and 4G-only connectivity, and the Pakistan price is set by sellers and PTA status rather than by Tecno — so the Rs. 43,999 figure is the floor, not a fixed official price. If slimness and display matter more to you than a multi-camera setup, it is a strong option; check the IMEI, PTA status and the final price before you buy.
