Simple answers about telecom APIs and VAS
A telecom recharge API is a set of programmable endpoints that lets a website, app, or POS system top up prepaid mobile, DTH, and data connections in real time, without building direct connections to every operator yourself.
VAS are services layered on top of a carrier's core voice and data network, such as bulk SMS, missed call alerts, OTP delivery, HLR lookups and SIM hosting, that give businesses extra ways to reach and verify customers.
An HLR lookup queries a mobile network's Home Location Register to confirm whether a number is active, which operator it belongs to, and whether it can currently receive calls or texts, helping clean contact lists and reduce failed sends.
A long code is a standard ten-digit number used for two-way SMS conversations, while a short code is a five- or six-digit number for high-volume campaign messaging; both let a business send and receive SMS at scale under a dedicated number.
A bulk SMS API lets a business send large volumes of text programmatically, commonly OTPs, transaction alerts, reminders and promotions, directly from its own software instead of a manual dashboard.
A multi-operator recharge platform connects one API or dashboard to every major mobile, DTH and data operator, so a retailer or distributor can process recharges for any network from a single login instead of separate operator portals.
