Defaultech Ltd
SMS marketing, hosting, and custom software — built to be reliable, economical, and ready for real traffic. From a single website to cloud, APIs, and bulk messaging across Greece, Cyprus, and beyond.
What we run
The original Defaultech brief still holds: reach customers on their phones, keep their sites online, and ship the software that ties the business together.
Reach customers the economical way. Opt-in lists, promotions, delivery reports, scheduled campaigns, Unicode, Sender ID, HTTP API, and SMPP for resellers who need speed at volume. Greece, Cyprus, and international routing with quality delivery — not the cheapest hop that disappears.
A wide portfolio, tailored instead of boxed. Shared and reseller packages, dedicated servers, domain names, and cloud when the workload outgrows a single box. Built for sites that actually have to stay up — including PHP stacks, control panels, and mail.
Offshore-grade delivery with short feedback loops: internet and Microsoft stacks, open source, UI/graphic design, mobile, databases, frameworks & CMS, third-party APIs, and networking. Qualitative, on time, cost-effective — the unglamorous version of “it shipped.”
Mobile marketing
The same path that has always worked for retail, services, clubs, and field teams — now on a modern gateway.
Step 01
Consent first. Clean lists beat rented ones every time.
Step 02
Promotions, reminders, name-days, stock alerts — scheduled or instant.
Step 03
Quality routing, concatenation, and delivery reports you can audit.
Step 04
The message becomes a visit, an order, or a booked slot.
How we build
Defaultech Limited has shipped software and infrastructure for years: consulting inside organisations, then staying to operate what we build. If you already use iSMS.gr, you are in the same family of platforms — bulk SMS, white-label reseller stacks, automations, and server monitoring baked into the messaging layer.
Contact
SMS route, a box that needs to behave, or a system that should have existed last quarter. Send a short brief. We answer like operators, not a ticket bot.
