YX 4G LTE 8/16/32/64 ports SMS Modem Pool Bulk Send SMS IMEI Change AT Command

Product Overview

This 4G LTE high-capacity SMS modem pool is built around one idea: a single USB connection to a PC and many independent 4G radios working side by side. Choose the frame that matches your volume — 8, 16, 32 or 64 ports — and every port takes its own SIM card and handles its own sending and receiving over the mobile network. Nothing is routed through a hosted service or an internet connection, so messages leave from hardware you own and control. It is a desktop unit: plug in the USB cable and your software sees each port as its own device. Messaging companies, telecom integrators and enterprise communications teams are the usual owners. If you are replacing an ageing pool or stepping off a rented sending route, the day-to-day setup stays the same.

Port Configurations

• 8 ports — eight SIM cards working at once; a sensible size for a first sending desk, a pilot campaign or a small team that shares one pool.
• 16 ports — a middle step for agencies that send SMS in large batches daily and want spare capacity for a second brand or client.
• 32 ports — the volume tier for platforms running campaigns, OTP traffic and alerts side by side through the working day.
• 64 ports — the largest single box in the range, for operations that would otherwise stack several smaller units.
• A switch on every port — each slot has its own power switch, so you can swap a card, top up a balance or take a faulty line out of rotation while the rest of the pool keeps sending.
• Density that saves space — one chassis replaces a desk full of dongles and their separate cables, and a single power adapter covers the whole pool.

Network Coverage & Module Options

The pool runs on 4G LTE networks, with GSM, CDMA and WCDMA kept in the mix for markets where the mix of coverage is different. Because the SIM cards live in the unit rather than in a separate appliance, the pool itself can serve as the hardware SMS gateway behind your own sending software, leaving routing, templates and reporting in the platform you already run.

Module choice follows where you operate. EC25 is the broad-coverage option, EC200A suits regional builds outside the US, Canada and Japan, and EC20 covers India, Russia and parts of Europe and Asia. Tell us the country and carrier you will be sending on and we will confirm the right module and the exact band list for that network before your order is packed.
