Service Providers e.g `airtime_providers` (and similarly `data_providers`, `cable_providers`)
Modify the list of **Network Brands** (e.g., MTN, Glo, Smile) that provide Airtime for the current country. Note: This filter modifies the available _brands/networks_, not the underlying API gateway.
**Before:** `[‘mtn’, ‘glo’, ‘9mobile’, ‘airtel’]` (Pulled from `country.json` based on the active country)
**Hook Example:**
```php
add_filter('airtime_providers', function($providers) {
// $providers is a simple array of network string IDs
if (!in_array('smile', $providers)) {
$providers[] = 'smile'; // Adding a new network brand to airtime
}
return $providers;
});
```**After:** `[‘mtn’, ‘glo’, ‘9mobile’, ‘airtel’, ‘smile’]`
