Our stocked model
The 64-Port 2G/3G GSM Modem Pool: 64 SIM channels in one chassis
Sixty-four independent GSM modem modules, each with its own SIM slot and SMA antenna connector, mounted in a steel desktop chassis and presented to your computer over USB.
The unit is split into two banks of 32 channels. Each bank connects to the host by its own USB-B port and every channel enumerates as a separate serial port, so any software that speaks standard AT commands can send and receive SMS on all 64 channels at once. Modules are individually switched and removable, which makes swapping SIMs or isolating a faulty channel straightforward.
It runs from 100 to 240 V mains and draws around 60 W. Antennas, a mains lead and a USB cable are in the box, and our USB setup guide takes you from unboxing to the first message. Full details, live stock and secure ordering are on the product page.
64 SIM channels
One modem, one SIM, one antenna per channel. Standard and micro SIM sizes fit.
USB 2.0 host link
Two USB-B ports (one per bank) plus USB-A ports for chaining a second unit.
AT-command control
Works with Windows and Linux SMS software that drives serial GSM modems.
2G/3G hardware
Registers on UK 2G networks now that 3G is switched off, and keeps 3G for other countries. Compatibility notes.
Why buy the 64-port model rather than a smaller pool
The 8, 16 and 32-port 2G models are available to order from supplier stock with a 3 to 5 week lead time. The 64-port unit is the one we hold in the UK, it ships within a working day, it is the only unit with 2G/3G modules, and per channel it is far cheaper than any of the smaller units.

View and buyGSM modem pool, SMS gateway, multi-SIM gateway: different names, similar hardware
Buyers search for this equipment under many names. GSM modem pool and SMS modem pool describe the hardware itself. SMS gateway or GSM SMS gateway describes what it does once software is attached. Multi-SIM gateway, multi-port GSM modem and 64 SIM modem all point at the same class of device, and 64 channel is simply another way of saying 64 ports.
Whichever term you arrived with, the unit we hold in stock is a 64-channel 2G/3G modem pool that works as a USB-connected SMS gateway. We have written short guides on the terminology so you can be sure you are buying the right thing:
Professional uses for a 64-channel modem pool
- Business notifications: appointment reminders, delivery updates and service alerts sent from your own SIMs, under your own control.
- Two-way SMS: inbound replies, keyword responses and customer service queues that need many concurrent channels.
- Machine-to-machine and monitoring: alarm, telemetry and status messages from equipment in the field.
- Telecoms testing: network, handset and SMS-routing test beds that need many simultaneous registrations.
- Broadcast, events and transport: sectors the UK government lists as having a good reason to hold multi-SIM equipment.
This equipment is supplied for lawful business, technical and communications use only. We do not supply it for unsolicited bulk messaging, fraud or evading platform controls. Our lawful use policy explains what we ask at checkout.

Questions buyers ask before ordering
Is the 64-port GSM modem pool in stock right now?
Yes. The 64-Port 2G/3G GSM Modem Pool is held in UK stock and the live quantity is shown on the product page. The 8, 16 and 32-port 2G models are available to order and are dispatched from supplier stock in 3 to 5 weeks.
Is a GSM modem pool the same thing as an SMS gateway?
Often, yes. A GSM modem pool is the hardware: a chassis holding many GSM modems, each with its own SIM. When that hardware is driven by SMS software it acts as an SMS gateway. Some people also use "SMS gateway" for cloud messaging APIs. We explain the overlap in GSM modem pool vs SMS gateway.
Will a 2G/3G modem pool work on UK networks?
UK 3G networks have been switched off, so in the UK the unit registers on 2G. EE, Vodafone and O2 (and the MVNOs that use them) continue to run 2G until at least 2029. Three has no 2G network, so Three SIMs will not register. Full detail is in our UK network compatibility guide.
Do I need to prove a lawful use to buy?
From 29 October 2026 the Crime and Policing Act 2026 makes it an offence to possess a device that can use five or more SIMs without good reason or lawful authority, and requires suppliers to verify buyers and keep records. Our checkout collects a short declaration and business details for that purpose. See lawful use and buyer verification.
How is the unit connected to a computer?
By USB 2.0. The chassis has two USB-B host ports, one for each 32-channel bank, and each modem channel appears as its own serial (COM or tty) port that accepts standard AT commands. Our USB setup guide walks through it.
Can I order more than one unit or ship outside the UK?
Online checkout covers UK mainland delivery for up to ten units. For larger quantities, non-mainland addresses or export, use the trade enquiry form and we will quote.
