G-Tab Mega 12 256GB 8GB is now in stock at Mascom International for KSh 22,000, sold from our Nairobi CBD store at Old Mutual Building, First Floor Room 4, Kimathi Street. This 12-inch tablet pairs a 2000x1200 INCELL screen with the MediaTek Helio G99 octa-core chip, 8GB RAM, 256GB of storage, and an 8800mAh battery. It runs Android 15 out of the box, takes two 4G LTE SIM cards, and supports MicroSD expansion. At KSh 22,000, the G-Tab Mega 12 gives Kenyan buyers a large screen and current software without the price of a name-brand slate.
The G-Tab Mega 12 suits university students at Kenyatta University, JKUAT, and USIU who read PDFs, join Zoom classes, and take notes on one device. It fits remote workers who split time between spreadsheets and video calls, and parents who want one shared screen for homework and cartoons. The 12-inch panel solves the cramped-phone problem: e-books, past papers, and split-screen work all fit without squinting. Dual SIM means the tablet doubles as a big-screen phone, so field staff can carry mobile data and calls without a second gadget.
At Mascom International, we're seeing steady demand for 12-inch Android tablets from buyers who want laptop-sized screens at tablet prices. The G-Tab Mega 12 answers that with 256GB of onboard storage, roughly double what many rivals near this price offer. Users report that the wide screen and dual speakers make it a strong pick for Netflix, YouTube, and long study sessions. Unlike other electronics retailers in Kenya, Mascom International lets you test the G-Tab Mega 12 in person before you pay, then ships it countrywide on pay-on-arrival terms.
Common Questions About the G-Tab Mega 12 Tablet
Is the G-Tab Mega 12 worth KSh 22,000 in Kenya's market?
Yes, for buyers who want a big screen and lots of storage without paying top-tier prices. The G-Tab Mega 12 gives you a 12-inch 2K display, 256GB storage, 8GB RAM, and an 8800mAh battery for KSh 22,000. Comparable 12-inch tablets from Samsung or Lenovo start well above KSh 40,000. You give up brand-name polish and guaranteed multi-year updates, but you gain screen size, storage, and dual-SIM calling. For students and home users, that trade lands in your favour.
Who should buy the G-Tab Mega 12?
Students, home users, and light remote workers get the most from this tablet. The G-Tab Mega 12 is built for reading, streaming, video calls, browsing, and note-taking rather than heavy editing or console-grade gaming. University students use it for e-books and Zoom lectures during late JKUAT and Egerton study sessions. Families use it as a shared screen for homework and shows. Small-business owners use the dual SIM to keep a data line and a call line on one device. It is a media-and-study slate, not a laptop replacement for demanding software.
How long does the G-Tab Mega 12 battery last on one charge?
The 8800mAh battery holds up to around 8 hours of continuous screen time, per G-Tab's rating. In everyday mixed use some reading, some video, some browsing most owners get through a full day before recharging. Streaming video and gaming drain it faster than reading or note-taking. The battery charges over the USB-C port using the included charger. For a screen this size, 8800mAh is a sensible capacity.
Can the G-Tab Mega 12 make phone calls and use mobile data?
Yes. The G-Tab Mega 12 supports Dual SIM 4G/LTE, so you can insert Safaricom, Airtel Kenya, or Telkom Kenya SIM cards and make calls, send texts, and use mobile data. This turns the tablet into a large-screen phone, useful for boda and field workers who prefer one big device over a phone-plus-tablet combo. It also runs dual-band Wi-Fi for home and office networks. You can hotspot other gadgets or stay online through your own SIM when Wi-Fi is out of reach.
How much can you store on the G-Tab Mega 12?
The G-Tab Mega 12 comes with 256GB of built-in storage, and you can add a MicroSD card for more. In practice, 256GB holds roughly 40,000 photos, dozens of downloaded films, and hundreds of apps and documents at once. Students can keep entire course libraries offline; families can download shows for road trips to Nakuru or the coast without burning data. If you fill it, a MicroSD card extends space further. This is one area where the G-Tab Mega 12 beats many cheaper 64GB and 128GB tablets outright.
Does the G-Tab Mega 12 run current apps and Android 15?
Yes. The G-Tab Mega 12 ships with Android 15, the current major Android version, so the Google Play Store, banking apps, M-Pesa, WhatsApp, Zoom, and Microsoft 365 apps install and run normally. The Helio G99 chip with 8GB RAM keeps several apps open at once for split-screen study and work. Heavier 3D games run at lower settings rather than maxed out, since this is a mid-tier chip. For reading, streaming, calls, browsing, and office documents, day-to-day speed stays smooth.
What are the G-Tab Mega 12 cameras like?
The G-Tab Mega 12 carries a 16MP rear camera and an 8MP front camera. The front camera is the one that matters most on a tablet: it handles Zoom lectures, Google Meet calls, and WhatsApp video clearly at close range. The 16MP rear camera scans documents, snaps whiteboards, and captures quick photos, though tablet cameras never match a good phone. For a study-and-work slate, the pairing covers the jobs most buyers actually do video calls and document capture without pretending to be a camera phone.
How does the G-Tab Mega 12 handle streaming and movies?
The 12-inch 2000x1200 screen and dual speakers make the G-Tab Mega 12 a comfortable device for Netflix, YouTube, Showmax, and downloaded films. The large panel shows more detail than a phone, and the wide body is easy to prop up on a desk or lap. Sound comes through the built-in K-Class speaker box.Download shows over Safaricom or Airtel data before long upcountry trips.
