Cheapest Data Bundles in Kenya: Safaricom, Airtel, Telkom and Faiba Compared

Buy the wrong bundle on a Friday night and you can burn through KSh 500 by Sunday without ever opening YouTube. The cheapest data bundles in Kenya right now come mostly from Airtel and Telkom on cost per GB, Faiba wins if you need serious volume for hotspot or streaming, and Safaricom stays in the picture mainly because it reaches places the others do not.

Quick answer: As of the latest check, Telkom’s Mambo 99 (7.3GB for KSh 99) and Airtel’s Smarta bundles (45GB for KSh 1,000, 90GB for KSh 1,500) sit at the very top for cost per GB, both under KSh 22 per gigabyte. Faiba is close behind and pulls ahead on raw volume for heavy users, with monthly bundles up to 210GB. Safaricom rarely wins on price but has the widest 4G and 5G reach, which is worth something if the “cheap” bundle drops to 2G the moment you leave your estate.

Last updated: 15 July 2026. Bundle prices below were verified in March 2026 and spot-checked again this month. Telcos change offers often, so confirm the exact price and data amount in the provider’s app or USSD menu (*544# on Safaricom, Airtel and Telkom, *544# or *111# on Faiba) before you buy.

Quick Comparison: Cheapest Data Bundles in Kenya at a Glance

How Do You Calculate Cost per GB on a Kenyan Data Bundle?

Cost per GB is the bundle price divided by the total data, and it’s the only fair way to compare a KSh 99 bundle against a KSh 2,000 one. A real example: Airtel’s Smarta 1000 gives 45GB for KSh 1,000, so KSh 1,000 ÷ 45 works out to about KSh 22 per GB, roughly a fifth of what Safaricom’s standard KSh 1,000 monthly bundle charges for the same money.

Two things this formula hides, though. First, some bundles bundle in minutes and SMS (Safaricom’s All-in-One range, Airtel’s Smarta plans), so a “higher” cost per GB isn’t wasted if you actually use the voice minutes. Second, cost per GB says nothing about coverage. A pesamarket.com comparison of 65 bundles across all four carriers is a useful starting point for the numbers, but it can’t tell you whether Faiba reaches your specific street in Ruaka.

What Are the Cheapest Daily Data Bundles in Kenya?

For a single day of browsing, Airtel and Telkom usually beat Safaricom by a wide margin, though Safaricom’s daily bundles still sell well simply because M-Pesa and the app make topping up painless.

Buying daily bundles every single day adds up fast (KSh 99 a day is close to KSh 3,000 a month), so treat these as a top-up for one heavy day, not your main plan.

What Are the Cheapest Weekly Data Bundles in Kenya?

Weekly bundles suit anyone who wants more breathing room than a daily bundle without committing to a full month, and this is where Faiba pulls clearly ahead if it covers your area.

Telkom also runs a Friday-only “Freedom Friday” promo (5GB for KSh 100) that beats everything else on this list when it’s active, but promo bundles like this come and go, so check the app before you plan around it.

What Are the Cheapest Monthly Data Bundles in Kenya?

Monthly bundles are usually the best value for anyone online daily, and right now the gap between the cheapest and most expensive monthly options is enormous.

Don’t judge Safaricom’s All-in-One bundles on cost per GB alone. They pack in voice minutes and SMS, so someone who calls a lot gets real value even though the headline data price looks weak next to Airtel or Telkom.

Safaricom Data Bundles: Paying for Coverage, Not the Cheapest GB

Safaricom rarely tops a price comparison, and that’s fine, because most people on Safaricom are paying for reach, not the lowest shilling per gigabyte. Communications Authority of Kenya data puts Safaricom at close to two-thirds of the country’s mobile broadband subscriptions, which tells you plenty about how many Kenyans value coverage and M-Pesa convenience over shaving a few shillings off every gigabyte.

Its no-expiry bundles (200MB for KSh 100, 500MB for KSh 250) are the standout for occasional users who hate watching data vanish unused, even though the cost per GB on those is the worst on this whole page. For daily users, the All-in-One range makes more sense once you factor in the bundled voice and SMS. Safaricom is the safer pick if you travel between towns often, need strong signal in rural areas, or simply don’t want to think about which SIM has coverage today.

Airtel Data Bundles: The Value Leader Right Now

Airtel has spent the last year genuinely closing the price gap with Safaricom, and as of March 2026 it’s arguably ahead. The Smarta bundles were quietly upgraded to 45GB for KSh 1,000 and 90GB for KSh 1,500, on top of thousands of Airtel-to-Airtel and cross-network minutes, SMS, and a 100% Airtel Money transaction fee cashback as airtime. Data on Smarta bundles is allocated daily and rolls over to the next day if unused, which beats Safaricom’s stricter “use it or lose it” pattern on similar plans.

Airtel is the strongest pick for students, heavy social media users, and anyone in an area with decent Airtel 4G. The catch is coverage depth outside major towns, so check signal in your specific area before switching your main line over.

Faiba Data Bundles: Best for Heavy Users With Coverage

Faiba, run by Jamii Telecommunications, competes hardest at the top end. Its monthly bundles scale all the way to 210GB for KSh 6,000, and its Family Monthly plan gives 135GB shareable across four lines for KSh 2,500, which works out cheaper per person than almost anything else on this page if you’re splitting it with family.

The catch with Faiba is that it’s a 4G-focused network with patchier coverage than Safaricom or Airtel, so it rewards Nairobi and other urban users far more than someone upcountry. Confirm coverage at your home or office before buying a Faiba SIM specifically for the price, because a cheap bundle on a weak signal is not actually cheap.

Telkom Data Bundles: Worth Checking If You Have Signal

Telkom’s Mambo 99 (7.3GB for KSh 99) is, on paper, the cheapest cost per GB on the entire market, and its Freedom Friday promo occasionally beats it. Telkom’s problem has never really been price, it’s coverage and consistency. Independent quality checks in the past have scored Telkom noticeably below Safaricom and Airtel on network reliability, so treat Telkom as a strong second-SIM candidate rather than your only line unless you already know your area has solid Telkom signal. I’ve kept a Telkom line as a backup for years mainly because Mambo bundles this cheap are hard to walk past, but Safaricom stays my main line for the reasons above.

Which Network Has the Cheapest Data Bundles in Kenya?

There’s no single permanent answer, because bundles change monthly and coverage varies street by street, but based on the current lineup: Telkom and Airtel lead on cost per GB across nearly every category, Faiba wins for heavy users who need volume, and Safaricom wins on reach even though it’s rarely the cheapest.

Which Data Bundle Is Best for Students in Kenya?

For most students, a weekly or monthly bundle beats buying daily bundles on repeat, because the cost per GB drops sharply once you move past 24-hour plans. Faiba’s Weekly 8GB (KSh 300) or Airtel’s Smarta 1000 (45GB, KSh 1,000) cover WhatsApp groups, Google searches, YouTube tutorials and Zoom calls without the constant top-up anxiety.

If you’re in a hostel and need enough for hotspot use on a laptop too, jump straight to a 40GB-plus monthly bundle rather than stacking smaller ones, since the per-GB cost improves the bigger the bundle gets. If you’re also thinking about paying for your own data through a side hustle rather than relying on pocket money, our guide on starting a small business in Kenya with KSh 10,000 is a good next read.

Which Data Bundle Is Best for TikTok, YouTube and Streaming?

Video eats data faster than almost anything else on your phone, so streaming needs a bigger bundle, not necessarily a “special” one. An hour of HD YouTube can use over 1GB, and TikTok’s autoplay format quietly racks up usage even when you think you’re just scrolling for ten minutes.

A few habits stretch any bundle further: drop YouTube to 480p when you don’t need full HD, turn on TikTok’s Data Saver, disable WhatsApp’s automatic media downloads, and save big app updates for Wi-Fi. If streaming is your main use case, Airtel’s Smarta plans or Faiba’s larger monthly bundles handle it better than Safaricom’s smaller data-only options, purely on volume for the price.

Which Data Bundle Is Best for Online Work and Small Business?

Online workers and small sellers need stability more than they need the absolute cheapest shilling per GB, because a dropped call during a client meeting or a failed upload while listing stock costs more than the data saved. A monthly bundle in the 40GB-plus range, on a network with solid coverage where you actually work, beats a cheaper bundle that keeps dropping to 2G.

If you’re managing WhatsApp Business, uploading product photos to Facebook Marketplace, or handling M-Pesa transactions all day, budget for a backup SIM on a second network too. It’s worth reading our roundup of online jobs in Kenya if remote work is new to you, or our guide to e-commerce opportunities in Kenya if you’re planning to sell online.

Are No-Expiry Data Bundles Worth It in Kenya?

No-expiry bundles are worth it only if you use data rarely and hate losing it, because the cost per GB is roughly ten times higher than a normal monthly bundle. Safaricom’s KSh 100 for 200MB and KSh 250 for 500MB both work out to about KSh 500 per GB, against roughly KSh 22 to KSh 100 per GB on standard expiry bundles.

I’d genuinely be careful trusting these bundles to stay put, too. Safaricom quietly halved its no-expiry allocations in late 2025, effectively doubling the price per MB overnight, and only reversed the cut after public backlash and reinstated the original rates in December that year. It’s a reminder to check your balance after buying, not just assume the bundle you paid for is the one you received.

How Do You Choose the Best Data Bundle in Kenya?

Picking the right bundle comes down to matching it to where you are and how you actually use your phone, not just chasing the lowest headline price.

1. Check which network has strong, reliable coverage where you live and work, not just where you’re standing right now.
2. Decide whether you need daily, weekly or monthly data based on how consistently you use your phone.
3. Compare cost per GB, not the sticker price, using the tables above as a starting point.
4. Check the expiry window and whether unused data rolls over.
5. Check whether the bundle bundles in WhatsApp, SMS or voice minutes you’ll actually use.
6. Confirm the offer is available to everyone, not a personalised Tunukiwa deal shown only to some numbers.
7. Watch for out-of-bundle charges once your data runs out.
8. Turn on your phone’s built-in data saver mode regardless of which bundle you buy.
9. If you’re a heavy user, price out a home fibre or 5G router plan against your monthly mobile spend.
10. Recheck your usage every month or two and switch bundles if your habits have changed.

Final Verdict: Which Data Bundle Should You Buy?

If you want the lowest cost per GB and your area has decent signal, check Airtel and Telkom first, both are currently undercutting the rest of the market by a wide margin. If coverage and convenience matter more than shaving shillings, Safaricom remains the practical default, especially outside major towns. Faiba is the one to check if you need serious volume for hotspot or streaming and you’re within its urban coverage zones.

None of that is permanent. Prices here were current as of this update, and telcos in Kenya revise offers often enough that “the cheapest bundle” from six months ago can quietly become the most expensive one today. Check the app or dial *544# before you commit.
