Cross-network mobile transfers carry an interoperability fee, charged on both sides and visible only after the recipient is selected.
In Sub-Saharan Africa, every cross-network mobile money transfer carries an interoperability fee that same-network transfers do not. The fee is built into every licensed payment framework across Nigeria, Kenya and Ghana, but disclosed only at the confirmation screen, after the recipient is already selected.
Cross-network fees appear only at confirmation
Mobile money networks in Sub-Saharan Africa processed over $1.6 trillion in transactions in 2024, according to the Global System for Mobile Communications (GSMA) Mobile Money State of the Industry Report 2025, the largest volume of any region globally. The majority of those transactions cross at least one network boundary, moving between a wallet on one provider and an account at a competing network or commercial bank. That boundary has a cost.
Same-network transfers (M-Pesa to M-Pesa, MTN to MTN) are free or carry minimal fees in most markets. Cross-network transfers apply an interoperability fee set by the infrastructure operator. In Kenya, Nigeria and Ghana, this ranges from 1% to 1.5% of transaction value, according to each country's payment system operator fee schedules published in 2024–2025.
The disclosure gap compounds the cost. Most apps display the interoperability fee on the confirmation screen, after the recipient's number is entered and the destination network identified, but before the user confirms. This places the fee disclosure after the user has committed to a recipient, reducing the practical window to choose a lower-cost alternative.
A separate charge applies on the receiving side in certain markets. Some Nigerian commercial banks deduct a receiving fee before crediting the beneficiary's account. The sender completes a transfer and receives a success confirmation. The recipient receives less than was sent. Neither party sees a combined fee disclosure before the transaction is initiated.
Regulatory frameworks in all three markets require interoperability but do not yet standardise pre-transaction disclosure of the combined fee. The Central Bank of Nigeria, Bank of Ghana and Central Bank of Kenya each publish fee schedules for licensed payment service providers. These documents are public. They are not displayed inside the transfer flow at the moment the user selects a cross-network recipient.
Senders can cut costs using existing devices
The most direct action is to check the fee on the confirmation screen before pressing confirm. Every major mobile money app in Kenya, Nigeria and Ghana displays the transaction fee at the pre-confirmation step. Reviewing it takes three seconds and allows the sender to cancel and choose an alternative if the cost is higher than expected.
Where the recipient uses the same mobile money provider, same-network transfers cost less. For regular transfers to family members, suppliers or landlords, confirming which network the recipient uses and routing through the same network where possible is the simplest available cost reduction. Most frequent senders have more flexibility here than they realise.
For larger transfers, direct bank-to-bank routes may carry lower fees than mobile money interoperability. The Nigeria Inter-Bank Settlement System (NIBSS) Instant Payment system processes bank-to-bank transfers at a capped fee of NGN 50 (approximately $0.03) regardless of amount, more cost-efficient than a percentage-based mobile money fee for transfers above a certain threshold. Equivalent low-cap systems operate in Kenya and Ghana.
Households making regular cross-network transfers can calculate their annual interoperability fee cost in under five minutes. Multiplying the typical transfer amount by the applicable fee percentage, then by the number of monthly transfers and 12, converts the per-transaction cost into an annual household figure that is often larger than expected when stated in aggregate.
Fee schedules for all licensed mobile money operators are published on central bank and regulator websites. In Nigeria, the Central Bank of Nigeria (CBN) maintains an updated schedule at cbn.gov.ng. The Central Bank of Kenya publishes charges at centralbank.go.ke. The Bank of Ghana publishes equivalent disclosures at bog.gov.gh. All are publicly accessible at no cost.
Checking confirmation screen before sending recovers real money
The interoperability fee is a designed feature of every cross-network payment framework in Sub-Saharan Africa, not an error and not an exception. Households that check for it before confirming, route transfers within the same network where material cost differences exist, and use direct interbank systems for larger amounts recover real money on every transaction without changing how they bank.
