Services

Your network, your tariffs, your operational rules. We build telecom products around how your business actually runs instead of adapting a template we resell to every operator. That means native iOS and Android apps for your subscribers, internal tooling for your teams, and the services connecting them — designed so a new market or a new plan type doesn’t mean a rewrite.

Voice, video and messaging inside your product. We integrate SIP and WebRTC stacks, handle number provisioning, call recording and call quality on weak mobile networks, and build the in-app calling experience on top. Whether you’re adding calling to an existing app or building a softphone from scratch, the hard parts are codec handling, reconnection and battery — that’s the work.

End-to-end eSIM products: profile provisioning, activation, plan lifecycle and the customer-facing app your users actually touch. We work with GSMA-compliant provisioning and connectivity aggregator APIs, and we’ve shipped the activation flows — QR, activation code, deep link — where most eSIM apps lose their users.

Your app connected to the billing, CRM and provisioning systems already running your business. Real-time balance, usage counters, top-ups and subscription state stay consistent across every channel, so support agents and subscribers see the same numbers. We handle the retry logic and reconciliation that keeps that true when a third-party API goes down.

Aging telecom systems rarely allow a hard cutover. We modernize incrementally — replacing modules, extracting services and adding test coverage behind the scenes — so your service stays online while the codebase becomes something a team can work in again.

Release isn’t the finish line. We handle store submissions, OS and SDK migrations, monitoring and alerting, plus ongoing feature work. For products where downtime means unreachable subscribers, we agree response times up front.

SOLUTIONS

  • Build voice and video calling into your product with SIP or WebRTC — in-app calls, softphones, business calling, call recording, and quality that holds up on mobile networks.

  • Let customers install and manage eSIM profiles in a few taps: activation by QR or link, multiple profiles per device, plan switching, and transfer to a new phone.

  • Sell connectivity to travellers with a country and region plan catalogue, instant activation on arrival, data usage tracking, and top-ups without leaving the app.

  • Give subscribers their own account: plans, balance, invoices, top-ups and support requests — cutting the call volume your support team handles manually.

  • Payments, auto-renewal, promo codes and referral logic wired to your billing system, with local payment methods for each market you sell in.

  • Manage SIM and eSIM fleets at scale: bulk provisioning, usage limits per device, alerts on unusual consumption, and dashboards for your operations team.

OUR DEVELOPMENT PROCESS

  1. Discovery

    For every project, we discuss your problem, your subscribers, and your must-have features. Then we study your market, competitors and budget, and create a Discovery Report covering the development nuances, timeline and cost. Everyone stays aligned from day one.

  2. Requirement Analysis

    We go through features, user flows, security and compliance, and document every detail before development starts. For telecom products this is also where we list every carrier, provisioning and payment integration you depend on, so nothing surfaces as a surprise mid-project.

  3. Architecture & Planning

    At this stage we pick the right technology and plan the main steps. We design how your app talks to billing, provisioning and third-party services, then split the work into milestones you can follow and participate in — which lets us take your feedback in early.

  4. Development & Testing

    We build in two-week sprints and show you a working version at the end of each one. Every release is tested on real devices and real networks, because connectivity products behave differently on weak signal than they do in an emulator.

  5. Launch & Support

    We handle store submission, monitoring and alerting, then stay on for maintenance and new features. When your users can’t reach the network, they can’t wait — so we agree response times before launch, not after the first incident.
