Frequently Asked Questions

SMSCity is a white-label Bulk SMS Gateway Billing platform designed for anyone who wants to build and operate their own SMS gateway business — resellers, aggregators, ISPs, telecom startups, and IT companies in Bangladesh and beyond. You get the full software stack to own the business, not just use it.
No hardware is required for the Starter or Professional plans — you simply connect your existing operator API keys or SMPP credentials. For the Enterprise plan, SMSCity also supports SIM boxes and dedicated trunks if you want to own the physical infrastructure.
You create reseller accounts and assign a custom credit balance and per-SMS rate to each one. When a reseller sends an SMS, the credit is deducted instantly from their balance. You can top up their credit manually or set up automated balance alerts. Auto-generated invoices track all transactions for both you and the reseller.
Yes — fully. Professional and Enterprise plans include complete white-label support. Your resellers and clients log in to your domain with your logo, brand colours, and company name. All outbound emails (invoices, alerts, OTPs) are sent from your SMTP with your brand. SMSCity is never visible to end users.
SMSCity supports Masking (branded sender ID), Non-Masking (MSISDN sender), OTP/Transactional, and International routes. It connects via REST HTTP API or SMPP v3.4 protocol. Multiple gateways can be configured with priority order and automatic failover routing.
All plans include initial setup assistance and documentation. Professional plan customers get priority support via WhatsApp & Telegram (24/7). Enterprise customers receive dedicated account management, on-site or remote training, and optional source code access with custom feature development.
