Infinix Smart 20 with 64GB storage and 4GB RAM is available at Mascom International for KSh 15,700, brand new and sealed in its retail box. The Infinix Smart 20 pairs a 6.78-inch 120Hz display with a 5200mAh battery, the MediaTek Helio G81 chip and Android 16 with XOS 16. Its body carries an IP64 rating against dust and splashes, and Infinix rates it to survive drops of up to 1.5 metres. You can see and handle the Infinix Smart 20 at our shop in the Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, before you pay a shilling.
Built for first-time phone owners, university students, boda boda riders and small traders across Kenya, the Infinix Smart 20 covers the daily basics without drama. Many budget phones die by mid-afternoon or crack after one fall from a matatu seat. This one answers both problems: the 5200mAh cell carries a full day of calls, WhatsApp and M-Pesa, while the IP64 body shrugs off road dust and a sudden downpour on the walk home. A dedicated microSD slot lets you add storage later, so the 64GB model grows with you instead of forcing a new phone next year.
Unlike other electronics retailers in Kenya that sell grey imports with no paperwork, Mascom International stocks the Infinix Smart 20 with a 12-month warranty and the charger in the box. Customers across Nairobi tell us they want a phone that simply works for calls, mobile money and school WhatsApp groups, without paying for features they will never open. The Infinix Smart 20 64GB fits that need and costs KSh 2,800 less than the 128GB version. Walk into our Kimathi Street store to try it, or order on WhatsApp and pay on arrival anywhere in Kenya.
Common Questions About the Infinix Smart 20
How much is the Infinix Smart 20 64GB in Kenya?
The Infinix Smart 20 64GB with 4GB RAM costs KSh 15,700 brand new at Mascom International in Nairobi CBD. That price includes the charger in the box, a 12-month warranty and pay-on-arrival delivery to all 47 counties. If you want more room for photos and apps, the 128GB version sells for KSh 18,500, which is KSh 2,800 more, and the 256GB version costs KSh 20,500. All three share the same screen, battery, chip and cameras, so storage is the only real choice.
Should I buy the Infinix Smart 20 64GB or pay more for the 128GB version?
Choose the 64GB Infinix Smart 20 if your phone mostly handles calls, WhatsApp, M-Pesa and a few social apps. Both versions have 4GB RAM, the same 6.78-inch 120Hz screen, 5200mAh battery and Helio G81 chip, so speed and battery life match. The only difference is built-in space: the 128GB doubles it for KSh 2,800 more. Heavy photo takers and TikTok users should pick the 128GB. Everyone else can buy the 64GB and add a microSD card later through the dedicated slot.
Does the Infinix Smart 20 work on Safaricom, Airtel and Telkom 4G networks?
Yes, the Infinix Smart 20 runs on 4G LTE with Safaricom, Airtel Kenya and Telkom. Its spec sheet lists LTE bands 1, 3, 8, 20, 28, 38, 40 and 41 among others, a wide spread that covers 4G service from all three Kenyan networks. It holds two nano-SIM cards at once, so you can keep a Safaricom line for M-Pesa and an Airtel line for data bundles. The phone does not support 5G, which matters little at this price, since 4G reaches far more Kenyan towns.
How long does the Infinix Smart 20 battery last on one charge?
The Infinix Smart 20 carries a 5200mAh battery, enough for a full day of calls, WhatsApp, M-Pesa and some YouTube for most users. Light users who mainly call and text can often stretch into a second day. The phone charges at 15W through USB-C. Infinix does not publish a full-charge time, so plan an overnight or long lunchtime top-up. The 720p screen draws less power than sharper panels, which helps the battery last on long matatu rides or days away from a socket.
Can I run M-Pesa and Kenyan banking apps on the Infinix Smart 20?
Yes, the Infinix Smart 20 runs the M-Pesa app and Kenyan banking apps from the Google Play Store on Android 16. Its 4GB RAM keeps a banking app, WhatsApp and the browser open together without constant reloading. The side-mounted fingerprint sensor unlocks the phone quickly, and many banking apps let you use it to sign in. For small traders, Lipa na M-Pesa and Pochi la Biashara payments work as on any Android phone, with clear notifications on the 6.78-inch screen.
Is the Infinix Smart 20 a good phone for an elderly parent?
The Infinix Smart 20 suits older parents well because its 6.78-inch screen shows large text and big icons clearly. Android settings let you raise the font and display size in a few taps. The 5200mAh battery means fewer worries about a dead phone, and the IP64 rating guards against dust and splashes in the kitchen or shamba. The 3.5mm headphone jack and FM radio keep familiar habits alive. Our staff can set it up in store before you send it upcountry to Mum or Dad.
Can I add a memory card to the Infinix Smart 20 64GB?
Yes, the Infinix Smart 20 has a dedicated microSD slot, so a memory card does not take the place of your second SIM. You keep both lines active and still add storage for music, photos and downloaded videos. A memory card is the cheapest way to stretch the 64GB model. Keep apps on the phone's own storage for speed, and send photos, voice notes and documents to the card. Mascom International sells genuine microSD cards, so ask for one when you buy the phone.
Who should buy the Infinix Smart 20 64GB, and who should skip it?
Buy the Infinix Smart 20 64GB if you want a dependable phone for calls, WhatsApp, M-Pesa, Facebook and light YouTube on a tight budget. It also makes a sound backup phone or a first phone for a teenager. Skip it if you play heavy 3D games, shoot a lot of video or want sharp photos at night, since the 8MP camera and entry-level chip have limits. Those buyers should look at the Infinix Hot 70 or Tecno Spark 50 4G, both stocked at Mascom International.
