1. Core Capacity Rules 
● Physical SIM Mode: 1 physical SIM slot per port, total 64 physical SIM cards; all eSIM profiles are disabled and cannot be used.
● eSIM Mode: Each port supports up to 8 eSIM profiles for cyclic use, reaching a maximum of 512 eSIM profiles across 64 ports; all physical SIM slots are locked and unavailable in this mode.
This device adopts 4G LTE full-band module (FDD/TDD LTE, backward compatible with global 2G GSM network) and maximize SMS/MMS transmission efficiency. It integrates full-featured bulk SMS, automated USSD, SMPP 3.4, open HTTP API, remote SIM Bank and eSIM lifecycle management functions. It is the ideal core hardware for global cross-border SMS aggregators, cloud eSIM service providers, large enterprise notification systems and IoT alarm platforms. The built-in web management panel supports multi-browser access (Chrome, Firefox, IE, Opera) for global operation teams.

2. Exclusive Dual Running Modes
The physical SIM and eSIM resources are completely independent and non-simultaneous — enabling one mode will automatically disable the other. The web page corner has a dedicated eSIM status indicator to identify the current mode intuitively:
2.1 Physical SIM Mode (Blue "eSIM" Label on Web Page)
Status Indicator: The word "eSIM" in the upper right corner of the web page shows Blue, meaning eSIM function is disabled.
Resource Configuration: Insert 1 physical SIM card into each of the 64 slots, total 64 physical SIMs for SMS/USSD services.
Hardware Status: All physical SIM slots are active; eSIM profile storage area is locked.
Applicable Scenarios: On-premises IDC computer rooms, local SMS business with fixed physical SIM cards, and scenarios requiring on-site SIM maintenance.
2.2 eSIM Mode (Green "eSIM" Label on Web Page)
Status Indicator: After enabling eSIM and rebooting, the "eSIM" label turns Green, meaning eSIM function is fully activated.
Resource Configuration: 8 eSIM profiles per port for cyclic scheduling, total 512 eSIM profiles; supports remote over-the-air (OTA) provisioning.
Hardware Status: All physical SIM slots are disabled; eSIM profiles are stored in the device’s local onboard chip.
Applicable Scenarios: Global remote deployment, cross-region SMS business, cloud eSIM pool operation, and scenarios that frequently replace operator numbers without physical SIM plugging.

3. Core Functional
 ● eSIM Management
（1）eSIM Activation & Provisioning: Extract LPA activation string from eSIM QR code (Format example: LPA:1$rsp-eu.simlessly.com$8DBE8D00EA45CC75249C90E2F), select target port & slot, paste the code and click Write; after success, green ICCID/EID will be displayed on the eSIM Status page.
（2）eSIM Modification & Deletion: After writing eSIM profiles, the "Write" button changes to "Delete"; delete old profiles and rewrite new LPA codes to switch eSIM remotely.
（3）Per-port 8 eSIM Scheduling: Configure automatic cyclic rotation for 8 eSIM profiles on a single port to disperse traffic and reduce blocking risk.
（4）eSIM Status Monitoring: Real-time view EID, ICCID, online status and signal of all 512 eSIM profiles on the dedicated status page.
Note: eSIM OTA activation requires temporary network access; after successful provisioning, eSIM can work 100% purely offline.
● Powerful Bulk SMS & MMS System
（1）Dual SMS Encoding: Support PDU & TXT global standard formats, compatible with all global carrier SMS centers.
（2）Diversified Sending Modes: Instant bulk blast, timed scheduled SMS, conditional trigger sending (trigger by accumulated SMS / consecutive failed SMS); single SMS supports up to 300 ASCII characters, multiple recipients separated by semicolons.
（3）Multi-path SMS Forwarding: 4 mainstream forwarding protocols: SMS→HTTP (POST/GET), SMS→Email, SMS→SIP, SMS→GSM mobile number.
（4）SMS Control & Filter: Set daily/monthly/total SMS quota for each physical SIM/eSIM; custom number prefix blacklist and sensitive keyword filter to block spam.
（5）Full MMS Support: Custom MMSC, MMS Proxy and port per carrier; max 5 attachments (300KB each), support bulk MMS sending via web or API.
（6）SMPP 3.4 Dual Mode: Work as SMPP Client (connect upper SMS platform) or SMPP Server (accept third-party access); support delivery report and custom failed SMS retry rules.
● Automated USSD & AT Command Management
（1）Manual Batch USSD: Select any ports to send USSD commands in bulk for balance inquiry, package checking and service activation.
（2）Auto USSD Trigger: Three trigger rules: fixed cycle timing, accumulated SMS volume, custom time period; automatically extract balance data from USSD replies and display on the dashboard.
（3）PIN Management: Bulk PIN unlock for locked physical SIM/eSIM via web panel.
（4）AT Command Support: Built-in AT command terminal for device and card debugging.
● Intelligent Anti-block & Automatic Rules
Over 8 built-in auto-switch/lock policies applicable to both physical SIM and eSIM:
（1）SMS-based triggers: Accumulated SMS count, consecutive failed SMS, inbound warning SMS with keywords, SMS module error codes.
（2）Time-based triggers: Max continuous online duration limit.
（3）Port Inter-Call Keep-alive: Periodic internal dummy SMS between ports to simulate normal user behavior and avoid operator risk control.
（4）Custom lock duration: 0 (no lock) / custom seconds / -1 (permanent lock until replacement/rewrite).
● IMEI Customization
Support independent IMEI configuration for physical SIM and eSIM:
（1）Fixed IMEI: Manually input 15-digit IMEI (system auto-completes the check digit).
（2）Dynamic IMEI Pool: Define starting IMEI and batch quantity; device randomly selects IMEI when switching cards/profiles.
● Remote SIM Bank & Network Functions
（1）SIM Pool Docking: Native support for remote SIM Bank, active/passive SIM allocation modes, switch UDP/TCP for cross-border unstable networks.
（2）Network Protocols: Support Static IP, DHCP, PPPoE, PPTP VPN for NAT traversal.
（3）Remote Management: ERMS/ETMS remote cloud management, SNMP protocol support.
● System Management
Multi-user & role permission division, configuration backup/restore, remote/local firmware upgrade, log export and network packet capture tools.
