Ejoin SIMPOOL-512: 512 Ports SIM Bank Device – Centralized Control for Multi-Gateway Deployment
Couldn't load pickup availability
The Ejointech SimBank is a remote SIM card management solution designed to work seamlessly with Gateway. With this solution, SIM cards are centrally managed on the SimBank, while Gateways can be deployed in different locations without requiring local SIM card insertion.
What is a SimBank
SIMBANK is like a "SIM Card Vending Machine" for your SMS/VoIP gateways.
The Problem It Solves:
Imagine you have:
- 1000 SIM cards (from T-Mobile/Vodafone/EE/etc.)
- 10 gateway devices spread across different locations
Without SIMBANK:
🔧 You'd manually insert SIM cards into each gateway
🔧 Need to change cards? Physically swap them one by one → HUGE hassle!
With SIMBANK:
- All SIM cards live permanently in the SIMBANK (like a "card hotel")
- Gateways borrow SIMs remotely → no physical swapping needed
- Smart rotation:
- Gateway 1 needs a SIM? Automatically checks one out
- Done sending? Returns SIM to pool for others to use
Real-World Example 🌰:
Before:
Your team spends hours inserting 1000 SIM cards into 10 SMS gateways... then repeats tomorrow.
With SIMBANK:
- All 1000 SIMs stay safe in the SIMBANK
- 10 gateways auto-draw SIMs as needed
- Zero manual work → 100% Proceed via Cloud
Key Benefits:
✔ No more SIM card juggling (save 90% time)
✔ Central control (manage all SIMs from one dashboard)
✔ Scale effortlessly (add more SIMs/gateways anytime)
Tech-Free Summary:
"It's like Netflix for SIM cards – your gateways 'stream' SIMs on demand!"
(Need it simpler? Think of SIMBANK as the "brain" that feeds SIMs to your gateway "workers.")
