Subscriber ownership
The subscriber, the SIM, the number and the wallet stay yours.
Custody
Recipient balances are to be held by a licensed custodian and accessed through Saleem's interfaces; keys do not sit on the handset. This is the target operating model at launch.
Channel role
The operator provides USSD, SIM Toolkit and the SIM estate as a channel. Licensed partners perform regulated money movement, custody, conversion and payout as required in each jurisdiction. Saleem provides instruction validation, screening orchestration, routing, records and reconciliation under the agreed operating model.
Compliance responsibility
Saleem answers for screening and for the record regulators require. The operator answers for subscriber identity and its own licence conditions.
Integration
Where the operator runs a wallet, Saleem credits it by API and the operator's own menus carry the session. Where it does not, short-code sessions route to Saleem's handler over a secure connection, and where SIM Toolkit is used the applet is provisioned over the air to SIMs already in the field. No core network change is required.
