How to add SMS to 3CX? Comparing the solutions available in Poland

Companies that want to send and receive SMS in a 3CX PBX have several options in Poland. They differ in architecture, cost, and where the messages actually "live":

SolutionHow it worksHardware / platform requiredWhere you see the SMSRollout
ACTIO SIP Trunk with native SMSSMS handled directly by the operator, on the same number as voice callsNone – zero hardware, zero extra platformsIn the 3CX app's chat window (desktop and smartphone)Certified template, a few dozen minutes; ACTIO configures it for you

Hardware gateway (e.g. SMSEagle)Physical device with SIM cards connected to the company's networkDevice purchase + SIM cards + maintenanceDepends on configuration – usually the gateway panel or an integrationHardware installation and configuration on the company's side
Custom API integrationA developer connects the PBX to an SMS gateway via API (e.g. the 3CX API + SMS API)Developer work + code maintenanceDepends on the implementationA development project – days or weeks

The conclusion is simple: only ACTIO's carrier-based solution delivers two-way SMS natively in the 3CX chat, on your business number, with no hardware to buy and no second system to work in. Voice and SMS from a single operator also means a single contract, a single technical support line, and a single invoice.

SMS in 3CX – frequently asked questions (FAQ)

No. With ACTIO's carrier-based solution, SMS works at the SIP Trunk level – no devices, SIM cards or extra infrastructure required. A hardware gateway remains an option for installations that require a physical SIM card on site.
