Direct answer
Choose a VTU platform by testing fulfilment, wallet behaviour and support with small live transactions. Do not rank platforms from blog scores unless every cell has a source.
Criteria that matter
Inventory
Which networks and which plan types? SME, gifting and “corporate” routes are not the same product even when the gigabyte number matches.
Funding
Bank transfer, card, USSD or manual confirmation all create different delays. A platform that is cheap but slow to credit a wallet will stall a reseller during peak hours.
Reliability
Ask for a transaction reference after a test purchase. Confirm the value on the handset. Repeat at a busy time of day.
Support
Live chat volume is not evidence. Measure time-to-resolution on a failed order.
Reseller and API tools
If you need automation, read the actual API documentation. “We have API” is not documentation.
Fees and limits
Minimum wallet funding, transfer fees and reversal policy should be written. If they are not, treat them as unknown — not as zero.
