Mascom International stocks the Tinsik T90 at KSh 1,300, a brand new and sealed Dual SIM keypad phone with a camera, a wireless FM radio and a 12-month warranty. The Tinsik T90 has a black body and a round navigation key framed by a gold ring, which gives it a neater look than most phones at this price. Dual SIM is printed on the box, so you can run two lines from one handset. Walk into our shop at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, or order for pay-on-arrival delivery anywhere in Kenya.
Designed for people who juggle two numbers, the Tinsik T90 handles a work line and a personal line without a second phone in your pocket. Boda boda riders often keep a Safaricom line for customers and an Airtel line for cheaper calls home. Small-business owners in Eastleigh, Kariobangi or Kisumu's Kibuye market do the same with a business number and a family number. The Tinsik T90 lets them switch between both from the keypad. Its wireless FM radio also plays without earphones, so a rider waiting at the stage can catch the news between trips.
Where most Nairobi electronics shops push a pricier branded handset for Dual SIM, Mascom International offers the Tinsik T90 at KSh 1,300 with the same written warranty we give every phone. At Mascom International, we're seeing riders and traders buy two at a time, one for daily use and one as a spare. If you prefer a better-known brand, the Tecno T102 is in stock at KSh 2,050. Visit us on Kimathi Street to try the gold-ringed key yourself, or send a WhatsApp message and we will deliver the Tinsik T90 to your door.
Common Questions About the Tinsik T90
How much does the Tinsik T90 cost in Kenya?
The Tinsik T90 costs KSh 1,300 brand new and sealed at Mascom International, Kimathi Street, Nairobi CBD. That price includes the handset, battery and charger, a 12-month warranty against manufacturing defects and pay-on-arrival delivery to all 47 counties. The Tinsik T40 and Tinsik T80 cost exactly the same, but the Tinsik T90 is the one of the three with Dual SIM printed on its box. If two lines matter to you, it is the clear pick at that price.
Can the Tinsik T90 hold a Safaricom line and an Airtel line at the same time?
Yes, the Tinsik T90 is a Dual SIM phone, so it holds two SIM cards at once, such as Safaricom and Airtel Kenya, or Safaricom and Telkom. You can use one line for M-Pesa and customer calls and the other for cheaper calls to family. It is a calls, SMS and USSD phone, with no 4G or internet features listed on the box. Mobile money runs through USSD codes such as *334# for M-Pesa, with no data bundle needed.
Should I buy the Tinsik T90 or the Tecno T102?
The Tecno T102 costs KSh 2,050 at Mascom International, KSh 750 more than the Tinsik T90. That extra money buys the Tecno name, which many Kenyan buyers know, and access to Tecno's own service network across the country. The Tinsik T90 gives you Dual SIM, a camera and a wireless FM radio, as listed on its box, for much less. Choose the Tecno T102 if brand backing matters most; choose the Tinsik T90 if you want two lines at the lowest cost.
Is the Tinsik T90 a good phone for boda boda riders?
The Tinsik T90 suits boda boda riders who need a cheap phone they can take on the road without fear of losing an expensive smartphone. Dual SIM lets a rider keep a customer line and a personal line in one handset. Physical keys are easier to press with cold or gloved fingers than a touchscreen at a busy stage. Tinsik publishes no water resistance rating, so keep it in a zipped pocket during heavy rain on the road.
What does the gold-ringed navigation key on the Tinsik T90 do?
The round navigation key on the Tinsik T90 moves you up, down, left and right through menus, and the centre press selects an option. The gold ring around it is a design touch that sets this black handset apart from plainer keypad phones. A single large key is easier to find by feel than small arrow buttons, which helps when you scroll through contacts quickly. It also makes the Tinsik T90 easy to spot among a pile of similar black phones.
Which should I choose: Tinsik T90, Tinsik T40 or Tinsik T80?
All three cost KSh 1,300 at Mascom International, so the choice rests on features. The Tinsik T90 is the only one of the three with Dual SIM printed on its box, plus a gold-ringed navigation key. The Tinsik T40 lists Bluetooth and a colour screen on its box, while the Tinsik T80 has a rounded classic shape and a rear camera with flash. Pick the Tinsik T90 for two lines, the Tinsik T40 for Bluetooth and the Tinsik T80 for an older relative.
Is the Tinsik T90 worth buying in Kenya?
The Tinsik T90 is worth buying if you want a sealed Dual SIM keypad phone with a warranty for KSh 1,300. Two lines, a camera, a wireless FM radio and a 12-month warranty at that price make it strong value for a spare or work phone. It is less suited to anyone who wants long published battery figures, because Tinsik does not release talk-time or standby numbers. Buyers who care about brand resale value may lean towards Tecno or Nokia instead.
Who should buy the Tinsik T90, and who should skip it?
Buy the Tinsik T90 if you run two SIM cards and need a low-cost keypad phone for calls, SMS, USSD mobile money and FM radio. Skip it if you need WhatsApp, Google Maps, ride-hailing apps or banking apps, because it does not run apps. Riders who take orders through apps will need a smartphone such as the Itel A100c 64GB 2GB at KSh 8,300 at Mascom International. Keep the Tinsik T90 as the dependable second phone beside it.
Technical Specifications
Display
- Screen above the keypad on a slim bar body — easy to read call logs and messages held in one hand.
- Display size and panel type are not published by Tinsik — inspect the handset in our shop before buying.
- Keypad-only input with no touchscreen — the phone responds to firm key presses, even with damp fingers.
- Black front panel framing the screen — a tidy look that hides everyday smudges better than a light colour.
- Menus move with the round navigation key — scrolling through contacts and messages takes only a thumb.
Processor and Software
- Lightweight keypad operating system — switches on fast and handles calls and texts without lag.
- Chipset not published by Tinsik — the hardware is matched to calls, texts, camera and radio rather than apps.
- Dual SIM settings in the menu — choose which line makes calls and which line sends SMS by default.
- USSD support from the dialler — mobile money menus, airtime top-ups and balance checks run without data.
- No app installs possible — nothing runs in the background, and nothing can be downloaded by mistake.
Memory and Storage
- Tinsik does not publish internal memory or card-slot figures for the T90, so no capacity is quoted.
- Contacts saved to the handset — numbers from both SIM cards can sit together in one phonebook.
- On-phone SMS storage — texts and payment confirmations remain on the handset until you delete them.
- Camera photos stay in phone memory — confirm on WhatsApp whether your unit accepts a memory card.
- Intended for contacts, messages and occasional photos, not for storing songs, films or large files.
Camera
- Camera shown on the box — capture quick photos of a delivery address, a receipt or a parcel.
- Megapixel figure not published by Tinsik — image quality is basic and suited to reference photos.
- Works best in good light — outdoor daytime shots come out clearer than photos taken indoors at night.
- Launched from the main menu with the navigation key — a couple of presses and you are ready to shoot.
- Photos saved on the handset — view them later from the gallery menu without any app or data bundle.
Battery and Charging
- Battery icon printed on the box — the handset runs on a battery supplied in the box with a charger.
- Battery capacity and standby hours are not published by Tinsik, so we do not quote figures for either.
- Keypad hardware with no apps — two SIM cards add some drain, but far less than any smartphone.
- Charge fully before first use — a full initial charge helps you judge how long it lasts with your calls.
- Use the charger supplied in the box — it suits the handset better than an unknown roadside replacement.
Connectivity
- Dual SIM — two SIM cards in one handset, so a work line and a personal line share one phone.
- Wireless FM radio — listen to stations without earphones acting as the antenna.
- Voice calls and SMS on standard SIM cards — talk and text on either line without a data bundle.
- No 4G or internet features listed on the box — the T90 is a calls, SMS and USSD handset.
- Bluetooth is not listed on the T90 box — choose the Tinsik T40 if wireless earpieces matter to you.
