YX 64 ports Bulk Send SMS 2G GSM Modem Pool IMEI Change AT Command

Product Overview

Sixty-four SIM slots sit in one chassis, linked to your computer by a single USB cable. Each slot carries its own SIM, and every port behaves like a separate phone, so this multi-SIM SMS modem pool suits messaging teams that have outgrown a shelf of individual modems: SMS platforms and aggregators, enterprise messaging desks handling campaigns and verification codes, and IoT operations that push a steady stream of notifications. In daily use it stays beside the computer that drives it, with the SIM cards left in their slots and the bundled software handling the work from one screen.

Key Features

• All 64 slots live at once — every SIM stays registered and ready to work, so a campaign never has to wait while cards are swapped in and out by hand.
• Throughput built for volume — with all 64 ports busy the chassis can send SMS in large batches at roughly 96,000 messages an hour, which turns a job that would take a night into an afternoon's work.
• Ports work independently — each port is managed on its own, so a number that runs out of credit, hits an operator limit or simply needs a pause does not stop the other 63.
• Modular port design — each port can be lifted out and replaced on its own, so servicing one slot never means pulling 64 SIM cards out of service.
• One chassis, one cable — 64 SIM cards sit in a single unit that plugs into your computer over USB, replacing a bench of separate modems and the cable mess that comes with them.

Network & Coverage

This is a GSM modem for high-volume SMS built around quad-band 2G frequencies, and both module options, M26 and M35, cover the same four bands with full 2G frequency support. The point worth checking before you commit is the network itself: Australia, South Korea, Japan, the United States and Canada have shut down 2G, so a 2G-only unit cannot register there and buyers in those markets are better served by a 4G LTE model. Wherever 2G is still running, each of the 64 ports registers on the mobile network like a normal handset, and the slots accept whichever operator covers your traffic. If you are unsure which band your carrier uses, ask them before you order — a module matched to a live band is what gets the pool registered and working first time.

Software & Control

• SMS Caster and SMS Deliverer included — the sending software is part of the package, so there is no separate licence to buy before the first message goes out.
• AT command access — the pool answers standard AT commands, letting your own application schedule sends and check the state of individual ports instead of relying on the desktop tool alone.
• STK and USSD handling — carrier menus and USSD requests can be run from the pool, which is useful for prepaid balance checks and operator services across a 64-SIM setup.
• IMEI change — values can be set or changed port by port, from the bundled software or over AT commands.
