A Signal Across Three Continents: How Safaricom's Quiet OneApp Update Reopened the Money Door for Kenyans Abroad

On a Wednesday afternoon in north-west London, a Kenyan nurse named Wanjiku tried, for the eleventh time that month, to open the app her mother in Murang'a now relies on for everything. The icon loaded. The spinner turned. Then the screen blinked back to the white welcome page, asking, once again, that she insert her Safaricom SIM and use Safaricom mobile data to verify her identity. Wanjiku's Safaricom SIM was in a drawer in her Wembley flat, exactly where it had been since she landed in Britain four years ago. She closed the app, swore softly in Kikuyu, and opened the *334# menu instead.

That small, daily indignity has been the texture of life for thousands of Kenyans abroad since Safaricom replaced the familiar M-PESA app with the consolidated My OneApp in April. This week, almost without fanfare, the telco quietly rolled out the change those users had been demanding. According to the technology publication TechCabal, which first reported the update on 23 May, the app can now stay logged in when a phone hops from a Safaricom signal to Airtel Kenya — or, crucially, to the foreign mobile networks that the diaspora actually carry in their pockets.

It is the kind of fix that does not make a press release, but it changes how a Kenyan in Doha pays a school fee in Eldoret.

A super app that forgot the diaspora

When My OneApp went live, Safaricom presented it as the next step in a strategy of consolidation: a single front door to M-PESA, airtime purchases, fibre, customer care and a growing shelf of mini apps. The company has told reporters it intends to retire the standalone M-PESA and MySafaricom apps within six months of the OneApp launch, making the new platform the only path into its consumer ecosystem for the millions of people who use Safaricom services daily.

For users inside Kenya, the migration was almost invisible. The app simply appeared one morning, pushed by an over-the-air update. For users outside Kenya, the experience was very different. The new platform leaned on a security feature called SIM-binding, which checks that the physical Safaricom SIM or eSIM associated with the account is present and active on the device. The check is reasonable in principle. The implementation was not. As HapaKenya laid out in mid-April, the handshake required cellular data on a Safaricom network — Wi-Fi, no matter how stable, was blocked.

That single design choice turned a routine login into a small monthly tax. A Kenyan in New York who wanted to top up airtime for a relative had two choices: switch on international roaming and burn a roaming bundle to satisfy the app, or fall back to the older USSD route. Several users reported a second sting: even when activation succeeded, the session expired within roughly twenty-four hours, demanding the roaming dance all over again the next day.

What changed this week

The TechCabal report, citing the publication's own tests, says My OneApp will now remain active when a device switches between Safaricom and other mobile networks, including Airtel Kenya. Users who previously found themselves logged out the moment they wandered into an area with weak Safaricom coverage — or who carried a dual-SIM phone with Airtel as a backup — should, in theory, no longer be punted back to the activation screen.

For diaspora customers, the practical consequence is bigger than the headline suggests. Once a user has gone through the initial activation, the app should now survive on a Vodafone-UK signal in Manchester, an STC connection in Riyadh, a Telstra tower in Sydney, or a hotel Wi-Fi link in Dubai without dropping the session. That is the part that matters: the app is no longer a citizen of the Safaricom network alone.

One restriction, however, has not gone away. Initial activation still requires Safaricom mobile data. A diaspora user who needs to set the app up for the first time, or to reinstall it after changing phones, cannot do that over Wi-Fi from a sofa in Toronto. They must either travel home, borrow a Safaricom-rooted device, or pay for roaming data to complete the handshake. The wall has been moved, not demolished.

Why a login flow is a remittance story

It is tempting to file this as a small product note. It is not. The United States remains the single largest source of remittances flowing into Kenya, accounting for more than half of the inflows that the Central Bank reports each month. The United Kingdom, Saudi Arabia and the wider Gulf supply most of the rest. The Central Bank projects diaspora remittances will reach about 5.24 billion dollars in 2026, with monthly inflows now routinely above 400 million dollars. A meaningful share of that money lands, in the final mile, inside an M-PESA wallet.

When the front door to that wallet behaves badly for the people sending the money, the consequences are not theoretical. They show up as a missed school fee deadline, a delayed hospital deposit, an emergency airtime top-up that fails at the wrong moment. They also show up as a slow erosion of trust in the brand. The Consumer Federation of Kenya, COFEK, has already asked the Communications Authority to look into what it called the forced migration to OneApp; the diaspora friction was one of the headline complaints.

This week's update does not resolve every grievance, but it removes the friction users described most often: the silent logout that happened the moment a phone left the comforting blanket of a Safaricom mast.

What still hurts, and the workarounds that remain

Until Safaricom opens initial activation to Wi-Fi and any reliable internet connection, the workarounds the diaspora has been trading on WhatsApp groups for the past six weeks will stay relevant. The USSD code at *334#, accessible while a foreign SIM is roaming, has been the most quietly reliable channel. The classic M-PESA menu in the SIM Toolkit also still works on a Safaricom SIM, even one that is dormant in a drawer at home, provided someone there is willing to turn the phone on. And users with dual-SIM handsets have found that setting the Safaricom line as the primary data SIM before launching the app can occasionally rescue an activation attempt that would otherwise fail.

None of these are dignified. All of them are testimony to how heavily the diaspora has come to lean on a Kenyan telco that, until this week, kept treating distance as a security problem rather than a customer problem.

A small fix, a clearer signal

There is no triumphant announcement attached to this rollout, no executive quote about putting the customer first. The change appeared, as such changes often do, in the release notes that nobody reads. But its arrival matters. It is the first concrete sign since the OneApp launch that Safaricom has internalised what its diaspora users have been saying since April: that the people who keep the remittance corridor warm at three in the morning Nairobi time are not edge cases.

For Wanjiku in Wembley, the next test will come the next time her mother asks for help with a chemist's bill in Murang'a. If the app opens, stays open, and lets her send the money without first asking her to fish out a SIM card she has not used in years, the silent update of 23 May will have done its real work. If it does not, she still has the USSD menu. But the direction of travel, at least, has finally turned outward.
