Who we are





Global Telco Consult (GTC) is an independent and trusted A2P business messaging consultancy with deep knowledge and experience in launching, optimising, and accelerating messaging services and strategies. GTC provides tailor-made messaging strategies to Enterprises, Messaging Service Providers, Operators, and Voice Carriers. The GTC team has expertise in multiple messaging channels such as RCS, Viber, WhatsApp, Telegram, and SMS for the wholesale and retail industry.

Customers can select from GTC’s unbiased consultancy, managed services or revenue assurance offerings. GTC supports its customers from market strategy through service launch, running the operations, and supporting sales and procurement.

GTC CEO & Founder José García encountered many companies that wanted to invest in mobile messaging solutions – but didn’t know how to start. This is how GTC came to life in 2016 – with a mission to guide Operators and Telcos to embrace this exciting opportunity and make the most out of business messaging.

Committed to the success of each customer, GTC has grown since then with Giovanni Benini as COO & CFO and a team of widely recognised industry experts, all of whom have decades of experience working in the messaging industry for various successful market players. GTC is proud to be independent of any specific player’s product or agenda.
