UzobestGSM

Telecom wholesale VTU platform for resellers and agents

UzobestGSM is a telecommunications wholesale and VTU platform in Nigeria — offering cheap data, airtime, cable TV (DStv, GOtv, Startimes), electricity bill payments, bulk SMS, and educational PINs. ScalerDev built the web platform at uzobestgsm.com and the Android mobile app, serving resellers and end users with wallet funding, secure PIN transactions, and developer API access.
